Subject: [PATCH] Don't run entity collision code if not needed
|
|
|
|
Will not run if:
|
|
Max entity cramming is disabled and the max collisions per entity is less than or equal to 0.
|
|
Entity#isPushable() returns false, meaning all entities will not be able to collide with this
|
|
entity anyways.
|
|
The entity's current team collision rule causes them to NEVER collide.
|
