Detailed Description

Identifiers for objects that are unique among ALL TILEMAP objects and persistant between Engine Locking cycles.

These should be used in cases longer than one unilayer_loop_iter(), as a MEMORY_PTR may be relocated in memory when unlocked and array indexes may change if the array is compacted.

Macro Definition Documentation

SPAWN_GID_PLAYER

#define SPAWN_GID_PLAYER   0xffff

Special case unique identifier for the spawner of the player-controlled MOBILE.

This should exist only on one tilemap (the first tilemap loaded in a new world).
