@Jynox_
add this script to your player. i didn’t test it but it should work fine;

public bool disablePlayerScript;
   private PlayerMov pm;

  void Start(){
   pm = this.GetComponent ();
}

void OnCollisionEnter(Collision col){
  if(col.transform.tag == "obstacle"){
    disablePlayerScript = true;
  } else{
    disablePlayerScript = false;
  }
}

void Update(){
  if(disablePlayerScript == true){
  pm.enabled = false;   //this disables your PlayerMov script
  } else {
    pm.enabled = true;
  }
}
