Layers

The mainstream LittleBigPlanet games use an engine that handles physics within distinct layers. Each game has 3 thick layers separated by 4 thin layers except for LBP3, which uses 16 thick layers separated by 17 thin layers and LbpPsp That has 2 layers separated by 3 thin layers. Sackboy and objects may occupy a thick layer, but only objects may be in thin layers.

Examples

 * The No-Join Post's base occupies one thick layer. The Post itself does not occupy any layers (and therefore has no hitbox).
 * Switches occupy one thick layer each.
 * The Scoreboard's base occupies three thick layers (and the thin layers between those thick layers) (though if the scoreboard is destroyed, the base's depth may be changed). The Scoreboard itself occupies one thin layer.
 * Checkpoints occupy the thick layer in a unique way: they are part of the "theck" sublayer, which does not collide with "thack" objects in the same layer.
 * A simple way to remember this is to note that "theck" rhymes with "check". This is also the basis for the name "theck".
 * Sackboy, Score Bubbles(?), Prize Bubbles(?), and Collectabells(?) occupy the thick layer in a unique way: they are part of the "thack" sublayer, which does not collide with "theck" objects in the same layer.
 * A simple way to remember this is to note that "thack" rhymes with "sack". This is also the basis for the name "thack".
