sprite.setCategoryBits

Section: Sprite Physics

What it does

sprite.setCategoryBits sets CategoryBits on a sprite object. It takes id and bits.

Signature

sprite.setCategoryBits(id, bits)

Arguments

  • id
  • bits

Example · generated

function start() {  const id = sprite.create('/sprites/hero.png', 100, 120);  sprite.setCategoryBits(id, 1);}

sprite.create is there to give the call something to act on; sprite.setCategoryBits is the line that matters. The code sits in start(), which the engine calls once, when the entity spawns.
