My Hostile actor moves toward my Player Actor. If it intersects an Obstacle it needs to not go through but treat as a wall. I've tried many different variations of turn(int) and move(int) /get and setRotation() from Player, etc. combinations but all are inconsistent and result in the Actor jumping through the Obstacle or speeding up, etc. The current method for collision detection and avoidance is bounceAtWall() in the Hostile Class posted below:

public Hostile(Player player){
this.player = player;

turnTowards(player.getX(),player.getY());

setRotation((int) (180 * Math.atan2(dY, dX) / Math.PI));
