A string specifying a collision mask layer.
In addition to the listed layers, there is "layer-13"
through "layer-55"
. These layers are currently unused by the game but may change. If a mod is going to use one of the unused layers it's recommended to use the collision_mask_util.get_first_unused_layer()
method from the vanilla library. When not using the library, mods should start at the higher layers because the base game will take from the lower ones.
