Socoder -> Cobra -> Value clipping help

 		I think I'm too sleepy, can't get this to work...

For a slider gui element, I want to clip the slider to certain values, e.g. every tenth of the bar.

This works:

offset = offset - (offset mod (width/(divisions-1)))

However, this always clamps to the lower value. I'd like to clamp to the nearest value, meaning sometimes I need to clamp upwards.

Any ideas?

 		Something like...

is what I think would work.

Index refers to which of the sections the slider is located in, from 0 (inclusive) to divisions (exclusive).

So if the width is 100, and there are 5 divisions, then the increment is 20. The first position (at index 0) is 10 (20/2 + 0*20) whilst the last position (at index 4) is 90 (20/2 + 4*20).

Hope that helps!

Do you really need the else of the if-then-else there? Setting a value to itself is effectively a no-op.

 		It was probably a leftover from a trial+error thing. I leave loads of those things all over the place!

 		Oops, turns out it's "slider.sliOffset = slider.sliOffset - o3"... don't know how that disappeared!
