Merged
Conversation
This function allows for ZScript code to get an array with all enemies of the caller found in range. Using similar sight logic as functions like LookForEnemies().
This parameter allows the function to also find players around it.

Also added a X_WRITE_NIL VM abort in case someone passes a null array to the function. |
Prevent crashes by passing a null array by reference.

This is a ZScript function that behaves more or less like LookForEnemies(), and optionally like LookForPlayers() too, and returns an array of pointers to every valid enemy it found in range (By passing an array by reference). Useful for custom look functions, such as for adding additional checks like a monster that only attacks flying enemies, or that can track multiple targets.
Below is an example mod with a test actor called EnemySearch, when spawned in, it will use the function to find every enemy in the area, print their name, and spawn a hovering plasma ball over their heads. When spawned as a friend with summonfriend, it will instead only do those two things with flying monsters.
