sp_target

Prototypeint sp_target(int active_sprite, int target_active_sprite[-1])

sp_target() gets or sets the target_active_sprite for the active_sprite.

The only sp_brains that directly use the target_active_sprite are 9 and 10 (enemy brains). If a target_active_sprite is set, the active_sprite will walk towards it and try to attack it. If the active_sprite has a sp_base_attack() sequence set, comes within sp_distance() pixels, and the sp_attack_wait() interval has passed, it will play the attack animation sequence.

Internally, the target_active_sprite is automatically set to 1 (the player sprite) when the missile hits another sprite.
