I have a bear trap class thats supposed to activate and play a closing animation , holding the animal in place for a few seconds and dealing a bit of damage . The problem is that the animation is playing as soon as the animal touches the edge of the trap, so it holds the animal in place and does damage, but the animal isnt in the bear trap, its to the right or left of it. How would i make it activate only when it touches the centre of the image.
Bear trap code:
