Subject: [PATCH] Remove streams from Mob AI System
|
|
|
|
The streams hurt performance and allocate tons of garbage, so
|
|
replace them with the standard iterator.
|
|
|
|
Also optimise the stream.anyMatch statement to move to a bitset
|
|
where we can replace the call with a single bitwise operation.
|
