How do I fix this cannon behaviour

I have been messing around with cannons and I have managed to get the cannon set to when the player touches the screen and a button to fire it, but when I click the fire button the cannon resets its angle to the direction of the button.

At the moment it looks something like this:

• Touch - is touching Background : cannon arm - set angle towards- touch.x touch.y
• button - on click : ball - set angle - Cannon arm.angle degrees

Anyone know why the angle resets to its starting position when I press the button?

Any help appreciated

Maybe set the touch to make sure the touch isn't over the button . so make another condition with the is touching condtion that says isn't over fire button. It sound like the is touching is still activating cause even though it over the button its technically still over the background.

ah ok ill try that now thanks for the reply.
