Scales how fast you can move in a given direction. 1.3 Mouse Sensitivity and Config. or Slash in Quake Champions. That's it! The term Source port comes from source code as after the release of the specific game's source code by the developers, third party developers and progammers began to create their own engines for the main game. When this is on, crouch slide only ticks down when actually sliding. GoldSrc, Source and Source 2 are based off of Quake code. WadingSpeedScale: double Most of them are self-explanatory, but CSlide is only familiar to those familiar with Quake 4, Thank you for reading! Basically this means that if the player is moving fast, and they try to accelerate backwards, it will read interpret the velocity as negative, and allow acceleration to counter it, and then accelerate up to the movement cap in the reverse direction. You should have received a copy of the GNU General Public License, along with Foobar; if not, write to the Free Software, Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA, Handles both ground friction and water friction, // proper way (avoids strafe jump maxspeed bug), but feels bad. Libretro Tyrquake [libretro/tyrquake] Mirrors: QuakeEngines , Other forks Libretro port of Tyrquake (Quake 1 engine) qengine [klaussilveira/qengine] Ground{Forward,Backward,Side,Up}Scale, Air{Forward,Backward,Side,Up}Scale, Water{Forward,Backward,Side,Up}Scale, Fly{Forward,Backward,Side,Up}Scale, CSlide{Forward,Backward,Side,Up}Scale: double This is what bunnyhopping looks like in-game to a skilled player: One Example of Bunnyhopping in Counter-Strike: Source (Source). the folder, not its contents. Most of them are self-explanatory, Tyr-Quake is a branch of the Quake source code released by id. Most of this is covered in quakeaccel.txt as well. result in less friction. in half-times (in seconds): that is to say, the values represent how many seconds it published by the Free Software Foundation; either version 2 of the License, Quake III Arena source code is distributed in the hope that it will be, useful, but WITHOUT ANY WARRANTY; without even the implied warranty of, MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Questions about Quake movement when compared to Source games. This means that the player has a single frame to input the jump command without losing speed - another reason why bunnyhopping is so hard! Quake and Quake 2 have a physics quirk where jumping adds to your Z velocity if it's Unlike Quake which later received a official Source port by Id themselves allowing the game to run in OpenGL, Quake II's engine already had built-in OpenGL . CodeBlocks + MinGW (75MB) or Visual Studio Express 2012 (5 GB). net forward scale of 1.5 on the ground. quake movement code | Co-Packing You Can Trust. QGravity: double Notable features of Quake III include the . a halftime value of approximately 0.2012. 1.2 Rocket Jumping. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. The contexts are: QuakeAccelPlayer provides the following properties: UseQuakeAccel: boolean "Bunnyhopping" is an exploit of a very popular bug in games like Quake III Arena, Half-Life, and Counter-Strike. even if you jump immediately. VQ1Bunnyhop: boolean PlayerPawn.CheckCrouch: overridden to speed up crouching and uncrouching. Max speed (in u/tic) can be solved Acceleration and max speed are scaled and our Archived. Quake 3 and beyond just make your wish direction point upwards. Here is the key to this diagram: In the above example, the player is both moving and turning left. Quake 3 and beyond just make your wish direction point upwards. There are five contexts where acceleration, max speed, friction, and stopping speed can differ. LH's Quake 1.06 qc source: id1qc; LH's Quake 1.06 qc Multiplayer only: mponlyqc; Scourge_of_Armagon mission pack 1 src: hipqc; . friction is a server-defined variable of the approximate range 1-5. To explain this further, I need to first explain what vector projection is. holding jump made your strafejumping suck this is why. They multiply Here is what all of this looks like in code: Those of you who are familiar with the Source engine may once again recognize the sv_accelerate, sv_airaccelerate, and sv_friction convars in this code. friction value, and each column corresponds to a set framerate the engine's physics would be running at. Main Page; Our Services; Visit Us; Partners and Resources; Contact Us; quake movement code . This is more of a resource than a playable mod, although Bunnyhopping, or bhopping for short, allows a player to exceed the game-defined speed limit. Thus, it may be useful to you as a game developer to "implement" bunnyhopping into your game. That is, when he moves the mouse to the left he holds the a (left movement) key, and when he moves the mouse to the right he holds the d (right movement) key. 50% of your Z velocity from running up a ramp gets added to your jump velocity. Full source code included. Turning this on uses Quake 1's behavior, and keeping it off uses Quake 3's. The code is all licensed under the terms of the GPL (gnu public license). CrouchSlideTime: int This replicates a flaw in the Quake games where holding jump or crouch in midair lowers You signed in with another tab or window. GroundFriction, CrouchFriction, AirFriction, FlyFriction, WaterFriction, CSlideFriction: double Wouldn't you always hit the ground and thus lose speed? In Quake 4 and Quake Champions, the amount of time you fall has a positive and direct Quake III Arena source code is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. tic) with the equation v = a/(1-f). 1.1 Strafing. Source Engine movement code - This code was based off of the Quake engine code. For example, a value of 200 means that you'll be treated as moving at 200 u/s if you're Z velocity is added to your jump velocity. This concept is illustrated below. Keep in mind that both codebases contain engine-specific code so they aren't as easy to integrate as the code in this article. Regular friction values (such as Doom's 0.90625 friction above, and what you get from It is possible to change a #define and. EasyCrouchSlide: boolean For example, 0.5 means 50% of your Z velocity These values are in u/s. These values are in u/s. quake2.plg readme.txt readme.txt This is the complete source code for Quake 2, version 3.19, buildable with visual C++ 6.0. Quake 1, and to my knowledge none of the other Quake games, has a nice feature where Open /code/quake3.xcworkspace and it builds in one click !! you can play it to see what it's like. adds to your crouch slide time; for example, a value of 2 means for every tic you fall, When Quake physics are enabled, your Player.JumpZ value is set so that you jump It's intended to support Quake and Quakeworld while fixing little bugs that have come up over the years. Quake Client A good starting point to study Quake is the qwcl (client) project. gets added to your jump velocity. Quake 1 and Quake 2 set your Z velocity to constant values if you hit jump or crouch but UpScale only applies to the thrust you gain from +moveup/+movedown/+jump/+crouch, The projects have been tested with visual C++ 6.0, but masm is also required to build the assembly language files. 2 ways to go about it you can set the material type of the collider to have a "slippery" collision with a material like "Ice" or "ZeroFriction". Its Single Player segment is almost identical to multiplayer fights, although other players are replaced by bots. I know it's not exact, and it's pretty hard to strafe well when the viewport is so small. The projection of a vector a onto a vector b (also known as the component of a onto b) is "The orthagonal projection of a onto a straight line parallel to b" (To quote Wikipedia). This is preferable because it is faster to perform than a cosine calculation. This value Quake 1.5 source code, mapping FGD for trenchbroom and map sources Here is the release of the Quake 1.5 source code, modified map sources, and FGD made for the mod.

The result of this from the player's perspective is a rapid increase in speed. The actual friction calculation is very simple, and looks like this in code: Of course, friction is only applied when the player is grounded. certainly if not moving, } else if ( pm->ps->pm_flags & PMF_BACKWARDS_RUN ) {, if ( ! Architecture Above the latest-commit bar, on the very right, there's a download icon. PlayerPawn.DeathThink: extended to apply Quake style friction when dead. ===========================================================================. when in the water. From a code perspective, this is done in the CL_PredictMove method, first Quake engine decide the sentime limit for playable commands: cl.time = realtime - cls.latency - cl_pushlatency.value*0.001; When Quake physics are enabled, your Gravity value is set to this. acts the same as the standard Gravity property. Questions about Quake movement when compared to Source games. InstantZAdjust: boolean FlawedAirMove: boolean When disabled, use Doom physics. Your maximum acceleration in the five contexts. 2. Its creator, Id Software, licensed the engine (now retroactively referred to as IdTech 2) to many companies, including Valve. Quake 1 and Quake 2 set your Z velocity to constant values if you hit jump or crouch when in the water. to build the assembly language files. Yes, I know there's an official version released alongside the Quake remaster, but I was almost . Doom's default friction value is 0.90625, which at its fixed ticrate of 35 translates to easily given acceleration (in u/tic) and friction (in percentage of velocity kept per You can change the movement_scale variable to tune how fast you can accelerate or change direction in air. MaxGroundSpeed, MaxCrouchSpeed, MaxAirSpeed, MaxFlySpeed, MaxWaterSpeed, MaxCSlideSpeed: double And the original movement properties are preserved as well. Let's model this mathematically: Figure 2: Using projection to limit speed. This value scales how much your fall time The client hence predict what will be its position on the server at t+latency/2. In the clip above you may notice the player quickly wiggle his mouse left and right. The code behind Quake's movement tricks explained (bunny-hopping, wall-running, and zig-zagging) 45,990 views Jan 10, 2021 Explanation of how the player movement code in Quake gives. quake movement code takes for friction to reduce your velocity to half of its current value.

The dot product notation works because a dot product is equal to |a| * |b| * cos(). It is possible in any game that is based off of the Quake engine, such as Source. Quake was a first-person shooter released in 1996. Bunnyhopping earned its name because the player literally has to hop in order to gain speed. Figure 1: Projecting vector a onto vector b. Vector projection can be represented by the equation: Above, represents a dot product and b is the unit vector of b (that is, a vector in the direction of b and a length of 1). What you need: 1. Nevertheless it is still interesting to see the origins of the mechanic. your MaxStepHeight is set to this value. If you have a max speed you want to reach with a given acceleration, use f = (v-a)/v. If you are familiar with console commands in the Source engine, you may recognize this variable as sv_friction. Quake Source Code. Basic tips about weapon code:.touch is the function called when a projectile hits something (in this function self and other refer to the projectile and the hit entity, respectively), T_Damage and T_RadiusDamage are . Change the extension of the new ZIP file to ".pk3", and you should be good to go. not from flying up/down with +forward/+back. The Quake engine introduced many of the concepts still used in Source today, such as the modern variant of the . Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. if it detects that you're about to run off a ledge, it doubles your friction in an Higher values Scales the above DirectionScale properties in the given contexts. When he does this, he syncs his mouse movement with his movement keys. Work fast with our official CLI. without getting a sqrt(2) distortion in speed. Technical Writeup Explanation of how the player movement code in Quake gives rise to these three different player movement \"bugs\", with a quick look at TAS movement mechanics at the end.Big thanks to the Quake Speedrunning Discord for helping me out with getting TASQuake running on my machine, and for clarifying terminology.Here are the original C versions of the acceleration functions:https://github.com/id-Software/Quake/blob/master/WinQuake/sv_user.c#L190Chapters00:00 Introduction01:13 Acceleration on ground03:05 Zig-zagging03:54 Circle jumps04:17 Wall-running04:46 Acceleration in the air05:18 Strafe-jumping / power-bunnies06:21 Tool-assisted techniques07:23 Outro This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. together, so a ForwardScale of 1.2 and a GroundForwardScale of 1.25 gets you a Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. See the GNU General Public License for more details. Posted on 14 February 2015 by Flafla2. Contents Are you sure you want to create this branch? Do not override In vanilla Quake, ground friction applies for a single frame when you hit the ground, Latest package: http://jinotra.in/downloads/mods/doom/quakemovement/quakemovement-v1.2.pk3, Packaged downloads: http://jinotra.in/downloads/mods/doom/quakemovement. There was a problem preparing your codespace, please try again. The entry point WinMain can be found in sys_win.c.A quick summary of the code is as follows: WinMain { while (1) { newtime = Sys_DoubleTime (); time = newtime - oldtime; Host_Frame (time) { setjmp Sys_SendKeyEvents IN_Commands Cbuf_Execute /* Network */ CL_ReadPackets CL_SendCmd /* Prediction//Collision */ CL . The most important component of bunnyhopping is the concept of Air Strafing. Posted by 10 months ago. Determine the rotation of the legs reletive, Returns an event number apropriate for the groundsurface, Check for hard landings that generate sound events. Here is my implementation of the above concepts in code: Friction also plays an important role in bunnyhopping as well as Quake-style movment in general. This simulates that. I'll repeat here what I said before: Instead of limiting velocity directly, only the projection of the current velocity onto acceleration is limited. For the player character class, I recommend setting air control to 0 and adjusting the walk speed to your own preference. Check this out for nostalgia. Copyright (C) 1999-2005 Id Software, Inc. If you can hear the song in the background, it's Baby Got Back cove. // Accelerated velocity in direction of movment, // If necessary, truncate the accelerated velocity so the vector projection does not exceed max_velocity, // accelDir: normalized direction that the player has requested to move (taking into account the movement keys and look direction), // prevVelocity: The current velocity of the player, before any additional calculations, // accelerate: The server-defined player acceleration value, // max_velocity: The server-defined maximum player velocity (this is not strictly adhered to due to strafejumping), // ground_accelerate and max_velocity_ground are server-defined movement variables, // air_accelerate and max_velocity_air are server-defined movement variables, Creative Commons Attribution 4.0 International License. **NOTE: Source code was updated! This mini-project is a modding resource that allows you to quickly and easily add For quick reference, here are some pre-converted values. The linux version should be buildable, but we haven't tested it for the release. You can grab it here.You can check out some of the changes outlined in the previous rundown article.Included is improved weapon balance, an overhaul to the game's difficulty to bring it up across the board, further improvements and tweaks to monsters, and some new co-op features. After 4 physics ticks, Vp passes the server-defined speed limit Vmax and Va is truncated to account for this. Similarly to double jumping, jumping while moving up or down a ramp added your jump velocity Quake III movement code - This is the original Quake engine movment code that "started it all". your air acceleration, due to the engine zeroing out the Z component of your desired Scales your speed when wading through water (waterlevel = 1). Quake 2 Marines adds the whole Quake 2 arsenal to Quake 1 with a select menu to pick different marines and weapon loadouts. It is 20% more physically accurate!So I spent quite a while trying to figure out how to get a character to move around a wor. 12. This explains in part why bunnyhopping is such a skill-based mechanic. Cookie Notice If you want bhopping to be accessible to new players, you can add auto-bhopping where the player can simply hold space to automatically jump frame-perfectly. the f = (v-a)/v equation above) can be converted to half-time values with this function: halftime = lambda friction, ticrate: math.log(0.5, friction)/ticrate. A tag already exists with the provided branch name. If, in the ZIP you created, everything's still in the "pk3/" folder, you zipped Your maximum speed in the five contexts. If you would like you can check out the Quake III movement code or the Half Life 2 movement code on GitHub. In the game, players must find their way through various maze-like, medieval environments while battling monsters using an . Quake QuakeC source This is a list of all the QuakeC modules included in the QuakeC 1.01 source code released by John Carmack in 1996. ( pm->cmd.buttons & BUTTON_WALKING ) ) {, bobmove = 0.4; // faster speeds bob faster, Generate sound events for entering and leaving water, Generates weapon events and modifes the weapon counter, This can be used as another entry point when only the viewangles, Can be called by either the server or the client. FitzQuake Mark V source code Decompress the source.zip included. This should be all you need to implement bunnyhopping into your game. Don't worry if you don't understand C coding, as each step will be explained later in further detail. It differs from the other games in the Quake series (not counting Quake Live) in that it sacrifices the Single Player mode to focus on multiplayer. When off, you need to let go and re-press crouch between slides. Don't set this to -1; that'll cause a divide by zero error. QuakeAccelPlayer overrides the following methods: Thinker.Tick: extended to enable/disable Quake physics when Q_UseQuakeAccel changes. When Quake physics are enabled and you're in midair (not when you're swimming), Because the movement in Quake 3 and Quake 3 engine-based games is different, the method of gaining speed is also different; it's not possible to use the Half-Life style of strafing to gain speed. https://github.com/id-Software/Quake-III-Arena/blob/master/code/game/bg_pmove.c, https://github.com/ValveSoftware/source-sdk-2013/blob/56accfdb9c4abd32ae1dc26b2e4cc87898cf4dc1/sp/src/game/shared/gamemovement.cpp. The projects have been tested with visual C++ 6.0, but masm is also required. More info: https://minecraft.curseforge.com/projects/squakehttp://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2181015-squake-quake-style. Sets the minimum amount of time you can crouch slide when hitting the ground. A table to quickly convert Quake friction values to half-time To review, open the file in an editor that reveals hidden Unicode characters. This value is in units. In Quake 2, when swimming on the surface of a body of water and holding jump, your Negative values represent no hard speed cap. This process is done later in Source's code, for each movement mode, where forward and side move values are translated to vector form, and then split up into the unit vector and magnitude, for wishdir and wishspeed. By default, QuakeAccelPlayer is configured so that all of its movement styles act similarly Learn more. However, some Source engine based mods have added this ability back to the engine. When on, you don't. CrouchSlideTimeMax: int MidairStepHeight: double The higher friction is, the less slippery surfaces become. When enabled, use Quake physics. Quake Reignited's first major update, v1.1, is now available for download. When set to a value greater than Values equal to or less than 0 mean "no friction". to the game they first appeared in - so air movement acts like Quake 1, crouch movement acts (roughly 0.5). StopGroundSpeed, StopCrouchSpeed, StopAirSpeed, StopFlySpeed, StopWaterSpeed, StopCSlideSpeed: double Close. As a decidedly skill-based mechanic, competitive players love bhopping because it is so hard to master. This allows the player to exceed the maximum velocity in certain situations. Turning this on uses Quake 1's behavior, and keeping it off uses Quake 3's. Q2SurfaceTension: boolean Both are free. VectorScale( wishdir, wishspeed, wishVelocity ); VectorSubtract( wishVelocity, pm->ps->velocity, pushDir ); VectorMA( pm->ps->velocity, canPush, pushDir, pm->ps->velocity ); Returns the scale factor to apply to cmd movements, This allows the clients to use axial -127 to 127 values for all directions. See pk3/zscript/testclasses.txt for examples of how to make the player act like Go into the pk3/ directory, select everything in there, and zip it all up. If nothing happens, download GitHub Desktop and try again. A tag already exists with the provided branch name. The purpose of this article is to define what bunnyhopping is, why it is important to consider as a game developer, and how to implement it mathematically into your FPS movement code. For more information, please see our quake movement code | Co-Packing You Can Trust. This value is in tics. Are you sure you want to create this branch? With our approach in Unreal Engine 4, we have all this information in a single vector variable. Although it doesn't *perfectly* model the Q3 movement physics, it feels mostly the same. Seen in: Quake (1996) How to do it: Simultaneously tap jump and a strafe key in a repeating pattern alternating between left and right strafes. Air Strafing works because of the way movement acceleration is handled in the Quake Engine. This actually is not true in the Quake or Source engines because there is a 1-frame window where friction is not applied when the player hits the ground. The Quake III Arena sources as originally released under the GPL lice, Learn more about bidirectional Unicode characters. If you have a max speed you want to reach with a given friction, use a = v(1-f). necessary, but every Quake game has fast crouching, so I'd recommend keeping this. 1.4 CPMA Movement. If you have any questions or comments please feel free to post in the comments section below. RampJumpFactor: double Having its source code, in version 2.0, released on May 18, 1996 by John Carmack, this was the official editor used for the vanilla game as well as the first Quake editor to be released in some form to the public; the QuakeED's source code was available about a month before the first shareware . MagneticLedgeScale: boolean Quake III Arena source code is free software; you can redistribute it, and/or modify it under the terms of the GNU General Public License as. PlayerPawn.HandleMovement: overridden with Quake physics and movement. Sets the maximum amount of time you can crouch slide. DoubleJumpFactor: double Recall that in order to airstrafe you must sync your movement keys with your mouse movement. Autohop: boolean the other games in their entirety. It is possible to change a #define and build with only C code, but the software rendering versions lose almost half its speed. You will need the Quake III Arena baseq3 (not the demo version) and be sure to use the parameters "+set vm_game 0 +set vm_cgame 0 +set vm_ui 0" in order to use the dylib virtual machines. If you want to retain the skill-based nature of bunnyhopping then be sure to add this delay into your physics calculations. For Quake II a number of Source ports were created by third-party progammers and developers after the release of the source code by Id Software.A number of ports were also made for specific platforms, below is a list of them all. All code examples are open-source and free to use, as always. It takes great skill and accuracy to perfectly sync your mouse movement to your movement keys. This does not include any engine code, which was released separately in 1999 and was written in C. defs.qc subs.qc fight.qc ai.qc combat.qc items.qc weapons.qc world.qc client.qc player.qc monsters.qc doors.qc this with your own movement code. This is the complete source code for winquake, glquake, quakeworld, and glquakeworld. to position, then friction is applied to velocity. as high as this value says. (what's the point of using this if you do that, anyway?). to however fast you were going up/down the ramp, allowing for dramatically boosted jump heights Backing up that theory of being a design choice could simply be because Quake was rigid with player movement as it wasn't as developed. It has created entirely new methods of play and allows very exciting, fast-paced emergent gameplay. These values are Jump type: Strafe jump. when jumping up a ramp. examples. In Quake 4 and Quake Champions, your crouch slide time ticks down when holding crouch, In both Doom and Quake, acceleration is applied to velocity, then velocity is applied Obviously id took a tighter approach with Q3. This setting scales how much of your starting you can crouch slide for two more tics. Have you looked in the source code at all? In contrast, others like Daikatana and SoF had pretty tight movement compared to Quake 2. The Top 142 Quake Open Source Projects Topic > Quake Vkquake 1,381 Vulkan Quake port based on QuakeSpasm most recent commit a day ago Pbcharactermovement 820 HL2-style, classic FPS movement for Unreal Engine 4 implemented in C++ most recent commit 11 days ago Vkquake2 718 Each row corresponds to a Quake positive, rather than simply setting it. This is because if players didn't do this friction would reduce their speed. These values are in u/s. GroundSpeed, CrouchSpeed, AirSpeed, FlySpeed, WaterSpeed, CSlideSpeed: double Add short mouse swipes in . It's easy to read, I would start with the source one as it's code is way less messy. Privacy Policy. Quake Champions' tick rate isn't certain, but it's around 77 fps. 1.5 Crouch Sliding. Click that, choose ".ZIP", then unzip the ZIP file into its own directory. You signed in with another tab or window. Quake 3 and Quake Live typically run at 125 fps. This boolean enables vanilla Quake behavior. values is at the bottom of this README. attempt to prevent you from doing so accidentally. AutoSlide: boolean This value is in units. This setting scales how much that factors in; for example, 0.5 means "Time 0" is on the top left, Time 1 is on the top right, etc. Controls how quickly your speed degenerates in the five contexts. In the Quake III acceleration code, movement speed is limited in a very interesting and nonobvious way. See the. moving slower than that, and you will be slowed down accordingly. In Quakeworld and every Quake afterwards, ground friction never applies when bunnyhopping. Q2SurfaceTension: boolean Instead of limiting velocity directly, only the projection of the current velocity onto acceleration is limited. This rounds down when added to your crouch slide time. The friction functions will act like your speed is at least this value when slowing you down. However, it is a bit easier to decipher than the Quake engine. control = speed < pm_stopspeed ? Take some time to tweak these server-defined variables to your liking as they determine the feel of your game's movement. Note, however, that Vc still substantially exceeds Vmax! This value is in tics. Z velocity gets clamped, keeping you closer to the water than in other Quake games. QuakeEd is the level editor designed by John Romero and John Carmack to create the levels in Quake.
