Damn I cant get the slide constraint to work because I dont know what to animate. I tried animating the constraint but that doesnt work and it seems stupid to animate the nCloth translate because that would make the constraint redundant, wouldnt it?

I thought it works like any other nConstraint but it is 'loose' and can slide along the surface.... but im sure duncan will chime in with his infinite wisdom soon ;)

The slide on surface simply acts as a constraint that allows the surface attachment point to slide... you don't keyframe the slide(if that's what you are thinking of), it is simply a degree of freedom. You could create a second transform constraint on the cloth to pull it in some direction.

If you wish to keyframe a specific moving uv position on the surface, you could instead first create a follicle attached to the surface using the script available here:

Then parent a transform constraint to this follicle(if you want to affect some cloth cvs). The follicle uv could then be keyframed to define specific motion across the surface( for a zipper, for example ).

ahh thankyou Duncan, I see how it works now so effectively it responds to forces ie gravity. Yes I was trying to component select the constraint itself and animate that. Thats great, the follicle idea is a nice touch also.
