Subject: [PATCH] Remove some Streams usage in Entity Collision
|
|
|
|
While there is more down the collision system, remove some of the wrapping
|
|
Spliterator stuff as even this wrapper stream has shown up in profiling.
|
|
|
|
With other collision optimizations, we might also even avoid inner streams too.
