Subject: [PATCH] Allow removal/addition of entities to entity ticklist during
|
|
tick
|
|
|
|
It really doesn't make any sense that we would iterate over removed
|
|
entities during tick. Sure - tick entity checks removed, but
|
|
does it check if the entity is in an entity ticking chunk?
|
|
No it doesn't. So, allowing removal while iteration
|
|
ENSURES only entities MARKED TO TICK are ticked.
