This is probably very simple but I'm missing it. I have a sprite which is an arrow. I want the arrow to move along a line and stop to indicate how much gas is left in the car. I'm trying the Size and Position actions (this triggers when the user picks something from a drop down list) 'set position', 'move forward' or 'setX' 'setY'. All of them move the sprite, but it keeps moving off the screen. How can I just get it to move to where I want it and stop? It's like is running over and over again.
