You can use the Set Position action to position an object, and you might want to use the random expression to randomise the points.
For example Set Position > X: random(800), Y: random(480) would set the object's X and Y coordinates to a number between 800 (X) or 480 (Y).
It's then down to you to decide when this is triggered.
