It is a number, unique within a level, assigned with [[RWGTools]] to a "sid" entity field. It is required for gamecode to store information about levels that was already visited. Instead of entity number (assigned by engine when entity is spawned) SaveId cannot be reused when new entity is created. Also SaveId survives level editing and recompilation, allowing to extend existing game levels without [[break savegame | breaking saved games]]. |
