If the tree is less than 200 pixels away from the player horizontally

and the tree is less than 10 pixels away from the player vertically

and the tree is not currently attacking

Set CanWalk to false (stop the tree)

Enter Idle state

If the players x value is less than the trees x value (player is on left of tree)

Mirror the tree (turn it to face the player on the left)
