Make AI run from Player

[Persona]

I have an AI the relies on Force to move, but I need it to flee from the player's position once it reaches a certain distance. Normally this wouldn't be a problem, but once they hit a wall, they get stuck and using OnCollisionEnter doesn't help since they will force themselves towards the wall until they get locked. The game runs in 2D with the Z-axis locked. I tried the bounce material with similar results and raycasting is out of the question.

Question: How do I get the AI to flee from the player, but go the opposite way once it hits the wall, without touching the player?

var FromPlayer: Vector2 = Target.position - transform.position;
if(FromPlayer.magnitude < detectionRange){
rigidbody.AddForce(1,2,1, ForceMode.Impulse); 
    //rigidbody.velocity = -transform.forward * 2;

    if(transform.position.y == Target.position.y){
    rigidbody.AddForce(0, Random.Range(-1, 1), 0, ForceMode.Impulse);
    }

    if(FromPlayer.magnitude < 2){
    rigidbody.AddForce(transform.forward * 1, ForceMode.Impulse);
}

function OnCollisionEnter(other: Collision){
if(other.gameObject.CompareTag("Wall")){
rigidbody.AddForce (Random.Range(-2, 2), Random.Range(-1, 1), 0, ForceMode.Impulse);

    }

}

Hi,

Just one advise for checking the distance with the playes, take a look to colliders, specially to the OnTriger...() functions .

Then with the wall staff, I'm trying to figure out that what you want to get is just a constant minimum distance respect the player, so why not OnTriggerStay?

If you it is not exactly what you need, please give me more details.

Cheers,
