How to return an enemy to its original location after losing aggro?

Questions & Answers

So basically I have an enemy that, once you get close enough, will chase you around and try to attack you. Once you get far enough away, it will run back to where it was originally.

The issue I’m having is that once it runs back to where its starting point is, it just falls over and keeps running and falling over around that area.

Here’s what I have for code for that section:

if (inAggroRange()) {
		//In aggro range
			if (!inAttackRange()) {
				chase();
			} else {
				animation.CrossFade(animationAttack.name);
				attack();

				if (animation[animationAttack.name].time > 0.9 * animation[animationAttack.name].length) {
					impacted = false;
				}
			}
		} else if (!inAggroRange()){
			//Go back to home position
			if (!(transform.position == enemyHomePosition)) {
				animation.CrossFade(animationRun.name);
				transform.LookAt(enemyHomePosition);
				controller.SimpleMove(transform.forward * speed);
			} else {
			//Enemy is at home position
				animation.CrossFade(animationIdle.name);
			}
		}

I think your problem is here:

if (!(transform.position == enemyHomePosition))

Try to make a “looser” comparisson, because it’s possible that the enemy will never reach EXACTLY the position it started from (you’re moving him in steps).

Calculate distance from current position to enemyHomePosition and if it is below an acceptable constant, set your enemy as idle.

This is how I fixed it:

private readonly float maxDistanceToHomePosition = 0.6f; // change this value as you like

...

if((transform.position - enemyHomePosition).magnitude > maxDistanceToHomePosition)
{
...
}
