Graphic Move Buttons - Help!


OK, super new at this. Can anyone help me with a script that moves an object with an action on another object. For example, if I had a graphic "left arrow" button object in the game, and on a mouse click action on that object, it moves a player object. I know this sounds simple, but I can't figure it out! Thank you in advance!!
if you are only trying to move ONE object (obj_charector for example) use:
//all the code in here will be performed on said object
