Move to the next block ? on a grid?

Hi ya,
Is there a way to walk/move up, down, left, right to a block?
So if i pressed right on the keyboard the actor would move to the next block/square to the right ?
Thanks,
haha up, down, left, right sonic 1 cheat

If i hit a block it will move down a block ?
Using collide and don't wanna work
You want to stand on a block? Hit a block, with a shot or something? Or move the block in a certain direction?
You could make a rule that if block collides/overlaps with "ACTOR" then change attribute self.position.Y to self.position.Y - 50 or whatever. That would move the block down 50 pixels.
Is that what you're asking?
