sprite.setSnap

sprite.setSnap sets Snap on a sprite object. It takes id and bool.

sprite.setSnap(id, bool)

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

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