the performance update

new bongle update!

performance

• meshing, lighting, physics, visibility and the scene graph now run in wasm.
• meshing is about 2x faster, chunk loading about 3x, full light fills about 3.7x, and voxel raycasts 2 to 3x.
• light tiles replace the light volume, so lighting is only computed where it's needed.
• physics is faster too.

blocks

• candles (up to four per block) and lanterns, both can be lit and put out.
• torches and candles give off smoke, and flames rise from their tips.
• leaves fall from the underside of leaf blocks, and lava throws up drops.
• block emitters: any block can give off particles. cost scales with particles spawned, not with how many blocks have emitters.

editor

• the world editor works on touch, with per-tool buttons and a compact layout for small screens.
• an orientation widget with a compass, axes and cube.
• save, sign in and confirm dialogs match the editor's style.

characters

• characters lean from the waist, so the head moves with the torso.

touch and audio

• in games, a finger no longer counts as a mouse button, so games handle taps, holds and swipes themselves.
• touch controls can be restyled with css variables.
• one-shot sounds that would be inaudible are skipped, and at most 32 play at once.

for creators

• a few scripting apis changed, such as world position reads taking an out vector. see the docs if an older script stops building.

fixes

• character collision fixes against walls and ceilings.
• translucent blocks sort correctly when the camera is still.
• lighting: new chunks take in light from their neighbours, and darkening an area updates every affected cell.
• teleports snap to the new position instead of blending.
