melonjs/melonjs-effects-and-shaders

Utiliza esta habilidad para efectos de post-procesado, sombreadores personalizados, modos de mezcla y gradación de color en melonJS. Cubre los ajustes preestablecidos ShaderEffect, addPostEffect en renderizables y cámaras, la escritura de un efecto personalizado dual GLSL/WGSL, los builtins screen_texture, y por qué los efectos no hacen nada en el fallback Canvas. Se activa con: ShaderEffect, addPostEffect, removePostEffect, getPostEffect, VignetteEffect, GlowEffect, BlurEffect, PixelateEffect, ScanlineEffect, shader, GLSL, WGSL, uniform, setUniform, setTexture, setTime, blendMode, colorMatrix, screen_texture, toFrameTexture, post effect, filter.

¿Qué es melonjs-effects-and-shaders?

Esta habilidad proporciona una guía completa para trabajar con efectos de post-procesado, sombreadores personalizados y gradación de color en melonJS. Está diseñada para desarrolladores que utilizan melonJS (compatible con WebGL2 y WebGPU, con soporte limitado en Canvas) y cubre desde el uso de efectos predefinidos como ShaderEffect (VignetteEffect, GlowEffect, BlurEffect, PixelateEffect, ScanlineEffect) hasta la creación de efectos personalizados con GLSL y WGSL. También explica cómo aplicar efectos a renderizables o cámaras mediante addPostEffect/removePostEffect, y cómo utilizar el buffer screen_texture para operaciones complejas como transformaciones de color o convoluciones. Además, advierte sobre la limitación del fallback Canvas, donde los efectos shader no tienen efecto, y proporciona prácticas recomendadas para la depuración y detección del motor de renderizado. Es útil para cualquier desarrollador que busque añadir filtros visuales avanzados, modos de mezcla (blendMode) o matrices de color (colorMatrix) en sus juegos o aplicaciones con melonJS.

Individual skills in this repo

This repo contains 10 individual skills — each has its own dedicated page.

melonjs/melonjs-3d

Use this skill for anything 3D or 2.5D in melonJS — Camera3d, Mesh, InstancedMesh, Sprite3d billboards, Light3d, ground shadows, glTF/GLB scenes, and depth sorting. Covers the Y-down/+Z-forward convention that is the inverse of OpenGL, the cameraClass opt-in, clip planes, and what does not work on the Canvas fallback. Triggers on: Camera3d, Mesh, InstancedMesh, Sprite3d, Light3d, billboard, glTF, glb, 3D, 2.5D, depth, cameraClass, fov, setClipPlanes, setFog, fog, distance fog, height fog, heightFalloff, transparent, transparency, alpha, blendMode, fade, castGroundShadow, lit.

melonjs/melonjs-3d-assets

Use this skill when loading 3D models into melonJS — glTF and GLB scenes, OBJ/MTL models, materials, imported lights, node animation, ground shadows and GPU instancing. Covers level.load options including the async flag, the rightHanded conversion, and exactly what the loader does and does not support. Triggers on: glTF, gltf, glb, OBJ, MTL, 3D model, getGLTF, getOBJ, getMTL, GLTFModel, GLTFScene, level.load glb, rightHanded, lightIntensityScale, castGroundShadow, shadowGroundY, EXT_mesh_gpu_instancing, KHR_lights_punctual, skinning, Blender export, 3D asset.

melonjs/melonjs-camera-and-drawing

Use this skill for camera control and immediate-mode drawing in melonJS — following a target, viewport bounds, shake and fade, secondary cameras, and drawing shapes, lines and gradients inside a custom draw(). Covers world versus screen coordinate conversion, clipping and masking, and baking with CanvasRenderTarget. Triggers on: Camera2d, viewport, follow, setBounds, shake, fadeIn, fadeOut, worldToLocal, localToWorld, colorMatrix, renderer.fill, renderer.stroke, Rect, Ellipse, Polygon, Line, Gradient, clipRect, mask, CanvasRenderTarget, NoiseTexture2d.

melonjs/melonjs-loading-assets

Use this skill for loading and managing game assets in melonJS — the resource descriptor format, the full asset type list, preload versus load, retrieving loaded assets, base URLs and cross-origin settings, and the loading screen. Triggers on: loader, loader.preload, loader.load, resources, getImage, getJSON, getTMX, getGLTF, getVideo, getFont, setBaseURL, setOptions, crossOrigin, withCredentials, credentials, cookies, authenticated assets, CORS, asset, preload, LOADER_COMPLETE, loading screen, unload.

melonjs/melonjs-performance

Use this skill when a melonJS game drops frames, allocates heavily, or needs to scale to many objects. Covers object pooling, draw-call batching, atlases, baking with CanvasRenderTarget, instancing, culling and alwaysUpdate, the debug plugin, and where the real costs are. Triggers on: performance, slow, frame rate, fps, lag, pool, pool.register, pool.pull, batching, draw calls, InstancedMesh, culling, alwaysUpdate, inViewport, CanvasRenderTarget, optimise, profiling, debug plugin, memory.

melonjs/melonjs-physics

Use this skill for collision, physics bodies, movement, and spatial queries in melonJS — the built-in SAT world and the planck/matter adapters. Covers bodyDef vs Body, collision types and masks, the collision callback family and their firing rules, raycast/queryAABB/querySphere, and the behaviour differences between adapters. Triggers on: Body, bodyDef, collision, collisionType, collisionMask, onCollision, onCollisionStart, onCollisionActive, raycast, queryAABB, querySphere, PlanckAdapter, MatterAdapter, gravity, velocity, applyForce, isGrounded, SAT.

melonjs/melonjs-renderables

Use this skill when subclassing Renderable, writing a custom draw() method, handling pointer or click events on game objects, applying post effects and shaders, or controlling draw order. Covers the pos-relative draw contract, isKinematic and input, addPostEffect vs the deprecated shader property, and z-ordering. Triggers on: Renderable, extends Renderable, draw(, update(, isKinematic, pointerEvent, registerPointerEvent, onClick, addPostEffect, removePostEffect, ShaderEffect, addChild, z-order, anchorPoint, floating.

melonjs/melonjs-renderer-backends

Use this skill when a feature works on one machine and not another, when choosing or pinning a renderer, or when writing code that must degrade gracefully. Covers the WebGPU to WebGL 2 to Canvas fallback ladder, what each backend supports, capability detection, and the subsystems that warn once and then stop working on Canvas. Triggers on: video.AUTO, video.WEBGPU, video.WEBGL, video.CANVAS, renderer.type, supportsDepthBuffer, shaderLanguage, WebGPU, WebGL2, Canvas fallback, context loss, backen

melonjs/melonjs-scenes-and-state

Use this skill for scene structure and game flow in melonJS — Stage subclasses, the state manager, transitions, pausing, the update loop, timers and tweens. Covers onResetEvent versus the constructor, state.set before state.change, the camera and world lifecycle per stage, and pause-aware timing. Triggers on: Stage, state, state.set, state.change, state.transition, state.pause, onResetEvent, onDestroyEvent, onActivateEvent, onDeactivateEvent, PLAY, MENU, LOADING, update loop, GAME_UPDATE, timer, setTimeout, setInterval, Tween, freeze.
