From 4af42625a02fe9f3f9917b713e1cad862301de2c Mon Sep 17 00:00:00 2001 From: RHY3756547 Date: Sat, 24 Mar 2018 23:50:10 +0000 Subject: [PATCH 1/4] Initial implementation of Nitro Particles - Drifting particles and mini turbo (sans extra spark particles) - Slowdown particles (grass/sand/water) - Itembox collect particle - Wall collide particle (this is really extreme and there should probably be others) - Shader improvements, such as dithered shadows for alpha and reduction of artifacts. The best way to remove all artifacts would be generating normals for courses and using the diffuse direction as a more reliable indication of shadowed/not. - Fixed checkpoints not resetting on new laps. - Fixed me not being able to count to 3. (now 3 laps instead of 4) - Fixed battle mode courses crashing on load and during due to AI being funny (above 31, eg 36 for block fort) --- code/engine/cameras/cameraIngame.js | 2 +- code/engine/cameras/cameraIntro.js | 2 +- code/engine/cameras/cameraSpectator.js | 1 + code/engine/collisionTypes.js | 30 +- code/engine/controls/controlRaceCPU.js | 10 +- code/engine/ingameRes.js | 2 +- code/entities/decorations.js | 2 +- code/entities/itembox.js | 1 + code/entities/kart.js | 121 +- code/formats/spa.js | 107 +- code/glmatrix/gl-matrix-min.js | 40 +- code/glmatrix/gl-matrix.js | 8592 +++++++++++++++--------- code/particles/itemboxShard.js | 50 +- code/particles/nitroEmitter.js | 173 + code/particles/nitroParticle.js | 251 + code/render/nitroRender.js | 13 +- code/render/nitroShaders.js | 58 +- index.html | 2 +- 18 files changed, 6338 insertions(+), 3119 deletions(-) create mode 100644 code/particles/nitroEmitter.js create mode 100644 code/particles/nitroParticle.js diff --git a/code/engine/cameras/cameraIngame.js b/code/engine/cameras/cameraIngame.js index 1592ace..eaaf0ab 100644 --- a/code/engine/cameras/cameraIngame.js +++ b/code/engine/cameras/cameraIngame.js @@ -52,7 +52,7 @@ window.cameraIngame = function(kart) { var dist = 192; this.targetShadowPos = vec3.add([], kart.pos, [Math.sin(kart.angle)*dist, 0, -Math.cos(kart.angle)*dist]) -
