Subject: [PATCH] Entity add to world fixes
|
|
|
|
1) Chunk Registration might kill an entity, don't add it to the world if it did!
|
|
|
|
2) By default, entities are added to the world per slice iteration.
|
|
This opens risk of the slices being manipulated during chunk add if an
|
|
EntityAddToWorldEvent spawns an entity into this chunk.
|
|
Fix this by differing entity add to world for all entities at the same time
|
|
|
|
3) If a duplicate entity is attempted to add to the world of an entity, and
|
|
the original entity is dead, overwrite it as the logic does for unloaod queued entities.
