I need help implimenting sprite movement in gage.

I can't seem to get the sprite to stop at map boundaries.

here is some code, but the sprite still goes past the map. Also I can only return to the sprites origin. i.e. if
i start at 400,300, I cant walk back to 0,0.

            }

When you are checking to see if they are going to go out of bounds, you are forgetting to add the dirx and diry variables.

Should look more like this:
