// DESCRIPTION:
|

|
|
// DoAttack Behavior Implementation
|
||
|
|
// -- DoAttack will rotate the actor to face his current enemy, after the
|
||
|
|
// the rotation( with optional animation ) has completed, it will check
|
||
|
|
// if the actor is able to hit its current enemy with an attack. If that
|
||
|
|
// check is successful, then it will play its specified attack animation.
|
||
|
|
//
|
||
|
|
// Currently, you must put the attack commands inside the animation.
|
||
|
|
//
|
||
|
|
// ANIMATIONS:
|
||
|
|
// Attack Animation : Parameter
|
||
|
|
// Rotation Animation : Optional
