Release LittleJS 1.30 - Lit Billboards, Mesh Colliders and Grass · KilledByAPixel/LittleJS

New Demos

3D Grass - A field of 20000 blades in one draw call, bent by a vertex shader as gusts of wind roll across it
3D Lit Billboards - A cloud of sprites lit by a light drifting through it, bright near the light and dark in the shade
3D Mesh Collider - Walk a level made of one mesh: ramps, stairs and walls

3D sprites, particles and billboards are lit: by the lights, the sun, the ambient and the shadows, and roundLighting lights them as balls, for smoke and clouds a light shines into
MeshCollider makes any mesh part of the 3D level's collision: objects walk up ramps, climb steps and slide along walls as capsules, and a prop placed in the 3D level editor can collide by its shape with meshCollision
A Shader takes uniforms of the game's own, new Shader(code, '', {wind: vec2()}), changed each frame with setUniform and no recompile, in 2D and 3D
InstancedMesh3D.setDataAt gives each instance four numbers of its own that a Shader reads, like each blade of grass's sway
Icons in text: setTextIcon('coin', tile(5)) and any text shows the tile where :coin: is written, in drawText, drawTextScreen, the UI system and ImageFont
3D solid collision goes through a grid once there are many solids: 1000 solids update about four times faster, 2000 about ten times
Many more fixes from four review passes, see the changelog

3D sprites, particles and drawBillboard were always unlit and are now lit, so they look different: set emissive = 1 on a sprite object or particle emitter, or render3D.emissive = 1 before a drawBillboard of your own, for the old look; additive ones, like fire and sparks, are unchanged

The gamepad sticks' dead zone is round, so diagonals respond as straight pushes do
A glTF OPAQUE material that shares a texture with a MASK or BLEND one draws solid
A 3D collision callback that moves its object, like a portal, has its next contacts tested where it went
The 2D and 3D level editors: many fixes to areas, properties, paste, prefabs and autosaves
A small level, LDtk file or example link can no longer make millions of objects or hang the page
