How do I check position of sprite on screen (layer position)

hello to all

how to do this:

when ennemy player is on the left edge of the screen he need to change his direction to the right, and when he is on the right side of the screen he change the direction to the left.

thanks

There are two ways I can think of.

You can compare the X of the enemy every time the enemy leaves the layout, and then depending where it is you change it's direction.

Or, I don't know if this is the best way to do it, but this is how I do it, you can create invisible sprites that doesn't interfere with the game, and then you set the enemy to change directions every time it collides with the invisible object.

yeah thanks i was thinking of that, adding 2 objects for reversing direction, who finally solved that problem.

thanks
