quake movement source code

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. GroundSpeed, CrouchSpeed, AirSpeed, FlySpeed, WaterSpeed, CSlideSpeed: double Open /code/quake3.xcworkspace and it builds in one click !! Questions about Quake movement when compared to Source games. The result of this from the player's perspective is a rapid increase in speed. 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. Keep in mind that both codebases contain engine-specific code so they aren't as easy to integrate as the code in this article. 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. If nothing happens, download Xcode and try again. Negative values represent no hard speed cap. Let's model this mathematically: Figure 2: Using projection to limit speed. Wouldn't you always hit the ground and thus lose speed? FitzQuake Mark V source code Decompress the source.zip included. Bunnyhopping, or bhopping for short, allows a player to exceed the game-defined speed limit. Change the extension of the new ZIP file to ".pk3", and you should be good to go. When enabled, use Quake physics. With our approach in Unreal Engine 4, we have all this information in a single vector variable. When on, you don't. the other games in their entirety. Posted by 10 months ago. This is because if players didn't do this friction would reduce their speed. Quake 2 Marines adds the whole Quake 2 arsenal to Quake 1 with a select menu to pick different marines and weapon loadouts. tic) with the equation v = a/(1-f). 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. Quake Source Code. (what's the point of using this if you do that, anyway?). When on, you don't. Learn more. 12. holding jump made your strafejumping suck this is why. Editing your own Quake engine (2013) We are going to use FitzQuake Mark V's source code and Windows for this example as GLQuake's source code doesn't compile without many modifications. (roughly 0.5). This boolean enables vanilla Quake behavior. The actual friction calculation is very simple, and looks like this in code: Of course, friction is only applied when the player is grounded. In vanilla Quake, ground friction applies for a single frame when you hit the ground, Cookie Notice This is what bunnyhopping looks like in-game to a skilled player: One Example of Bunnyhopping in Counter-Strike: Source (Source). This value scales how much your fall time "Time 0" is on the top left, Time 1 is on the top right, etc. easily given acceleration (in u/tic) and friction (in percentage of velocity kept per 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 Don't worry if you don't understand C coding, as each step will be explained later in further detail. In the clip above you may notice the player quickly wiggle his mouse left and right. Max speed (in u/tic) can be solved In Quake 4 and Quake Champions, your crouch slide time ticks down when holding crouch, PlayerPawn.HandleMovement: overridden with Quake physics and movement. net forward scale of 1.5 on the ground. For more information, please see our Why, then, is it possible to bunnyhop at all? Tyr-Quake is a branch of the Quake source code released by id. certainly if not moving, } else if ( pm->ps->pm_flags & PMF_BACKWARDS_RUN ) {, if ( ! Quake 4 is usually locked to 60 fps, but Q4Max duels run at 90 fps. A tag already exists with the provided branch name. Check this out for nostalgia. gets added to your jump velocity. 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. This setting scales how much that factors in; for example, 0.5 means ( 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. This is more of a resource than a playable mod, although There is a lot of engine-specific/messy code in there so watch out. 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. friction is a server-defined variable of the approximate range 1-5. ForwardScale, BackwardScale, SideScale, UpScale: double A tag already exists with the provided branch name. In general, you can convert Quake friction values to half-time values with this Python function: halftime = lambda friction, ticrate: math.log(0.5, 1-(friction/ticrate))/ticrate. Archived. if it detects that you're about to run off a ledge, it doubles your friction in an Do not override Higher values 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 . If you would like you can check out the Quake III movement code or the Half Life 2 movement code on GitHub. StopGroundSpeed, StopCrouchSpeed, StopAirSpeed, StopFlySpeed, StopWaterSpeed, StopCSlideSpeed: double To explain this further, I need to first explain what vector projection is. For quick reference, here are some pre-converted values. your MaxStepHeight is set to this value. Use Git or checkout with SVN using the web URL. together, so a ForwardScale of 1.2 and a GroundForwardScale of 1.25 gets you a Don't set this to -1; that'll cause a divide by zero error. Quake is a first-person shooter game developed by id Software and published by GT Interactive.The first game in the Quake series, it was originally released for MS-DOS, Microsoft Windows and Linux in 1996, followed by Mac OS and Sega Saturn in 1997 and Nintendo 64 in 1998. It takes great skill and accuracy to perfectly sync your mouse movement to your movement keys. Air Strafing works because of the way movement acceleration is handled in the Quake Engine. Copyright (C) 1999-2005 Id Software, Inc. Turning this on uses Quake 1's behavior, and keeping it off uses Quake 3's. The linux version should be buildable, but we haven't tested it for the release. Quake 1 and Quake 2 set your Z velocity to constant values if you hit jump or crouch when in the water. The Quake III Arena sources as originally released under the GPL lice, Learn more about bidirectional Unicode characters. or Slash in Quake Champions. The next patch was taking a bit longer then I expected to be ready so I figured I'd release these files in the meantime instead of holding onto it before the patch. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Go into the pk3/ directory, select everything in there, and zip it all up. 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. 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 In the Quake III acceleration code, movement speed is limited in a very interesting and nonobvious way. 1.3 Mouse Sensitivity and Config. WadingSpeedScale: double If you ever wondered why 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. 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". Q2SurfaceTension: boolean It has created entirely new methods of play and allows very exciting, fast-paced emergent gameplay. 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 replicates a flaw in the Quake games where holding jump or crouch in midair lowers PlayerPawn.CheckCrouch: overridden to speed up crouching and uncrouching. 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. If you have any questions or comments please feel free to post in the comments section below. Here is the key to this diagram: In the above example, the player is both moving and turning left. The contexts are: QuakeAccelPlayer provides the following properties: UseQuakeAccel: boolean But there's a literal edge case. your air acceleration, due to the engine zeroing out the Z component of your desired Above the latest-commit bar, on the very right, there's a download icon. // Vector projection of Current velocity onto accelDir. you can play it to see what it's like. Are you sure you want to create this branch? "Bunnyhopping" is an exploit of a very popular bug in games like Quake III Arena, Half-Life, and Counter-Strike. AutoSlide: boolean attempt to prevent you from doing so accidentally. Obviously id took a tighter approach with Q3. This value is in tics. Quake Client A good starting point to study Quake is the qwcl (client) project. In contrast, others like Daikatana and SoF had pretty tight movement compared to Quake 2. I know it's not exact, and it's pretty hard to strafe well when the viewport is so small. Posted on 14 February 2015 by Flafla2. 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. like Quake 2, fly movement acts like Quake 3, slide movement acts like Quake 4, among other If you are familiar with console commands in the Source engine, you may recognize this variable as sv_friction. Work fast with our official CLI. GNU General Public License for more details. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Quake Reignited's first major update, v1.1, is now available for download. this with your own movement code. pm_stopspeed : speed; } else if (pm->watertype == CONTENTS_SLIME) {, //ZOID: If we are on the grapple, try stair-stepping, //this allows a player to use the grapple to pull himself. QGravity: double Click that, choose ".ZIP", then unzip the ZIP file into its own directory. After 4 physics ticks, Vp passes the server-defined speed limit Vmax and Va is truncated to account for this. This rounds down when added to your crouch slide time. Full source code included. However, some Source engine based mods have added this ability back to the engine. moving slower than that, and you will be slowed down accordingly. Quake 3 and beyond just make your wish direction point upwards. when in the water. values is at the bottom of this README. Scales the above DirectionScale properties in the given contexts. Technical Writeup This means that the player has a single frame to input the jump command without losing speed - another reason why bunnyhopping is so hard! If you want to retain the skill-based nature of bunnyhopping then be sure to add this delay into your physics calculations. 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). The friction functions will act like your speed is at least this value when slowing you down. Determine the rotation of the legs reletive, Returns an event number apropriate for the groundsurface, Check for hard landings that generate sound events. 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. Quake was a first-person shooter released in 1996. Values equal to or less than 0 mean "no friction". **NOTE: Source code was updated! To review, open the file in an editor that reveals hidden Unicode characters. Contents Quake 3 and beyond just make your wish direction point upwards. If you have a max speed you want to reach with a given friction, use a = v(1-f). I'll repeat here what I said before: Instead of limiting velocity directly, only the projection of the current velocity onto acceleration is limited. If you have a max speed you want to reach with a given acceleration, use f = (v-a)/v. Scales how fast you can move in a given direction. Questions about Quake movement when compared to Source games. even in midair. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. However, it is a bit easier to decipher than the Quake engine. This allows the player to exceed the maximum velocity in certain situations. Z velocity gets clamped, keeping you closer to the water than in other Quake games. when jumping up a ramp. This value is in tics. The client hence predict what will be its position on the server at t+latency/2. VQ1Bunnyhop: boolean 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). See pk3/zscript/testclasses.txt for examples of how to make the player act like not from flying up/down with +forward/+back. It is possible to change a #define and build with only C code, but the software rendering versions lose almost half its speed. friction value, and each column corresponds to a set framerate the engine's physics would be running at. Most of them are self-explanatory, but CSlide is only familiar to those familiar with Quake 4,
