How do you prevent sliding down slopes?

I am using something similar like the gravity system in the castle markio demo, including the jump routine.

The problem is when my actor is standing on a slope, ramp or stairway, he tends to slide down the slope, even if it's only slightly uneven. Of course I already use a Collision method that does NOT slide down slopes, but it's the additional gravity that is making it sliding down.

How did you solve this problem? Please don't point me to comlex Physics systems I don't want to rewrite my games, it's only this little problem I want to solve.

Thanks for you suggestions.

You could do it as simple as:

If CollisionNY(whatever)=0.0
Apply gravity
End If

Or you could do something like:

gravity = gravity * (1.0-CollisionNY(whatever))

Something like that anyways :)

thanks a lot!!! well, in my complicated spaghetti patchwork style code it wasn't THAT simple, but finaly I nailed it. phewh! :)
