Slide Question

[sebacame1]

Actually my slide attribute is working pretty well but i was wondering if there is a way to change it's way to work.

The thing is that if you step on a slide for example going up and there is a slide there, you teleport to the second slide and then you "walk" up it. So I though the problem is that the slide attribute first checks if there is another slide in its direction and secondly it makes the player "walk". My question is that if it is possible to change it so it first makes you walk and then it checks if there is another slide. It would be like the ice on pokemon games.
