Subject: [PATCH] Optimize explosions
|
|
|
|
The process of determining an entity's exposure from explosions can be
|
|
expensive when there are hundreds or more entities in range.
|
|
|
|
This patch adds a per-tick cache that is used for storing and retrieving
|
|
an entity's exposure during an explosion.
