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. Should hopefully finish up issues with #1223

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.
