How to add a slider button in a HUD ?

[chrixbed]

I try to add a slider button to my hud. I want to have a button that I can move to change the intensity of an effect similar to that controller:

Does anyone have a suggestion on how to dynamically set the position of an object on a HUD on a mouse's left click?

One thing I don' think was mentioned in those other threads: If you use a prim-position method, you probably want to add some extra touchable space around the visible part of the prim (make the texture have a large transparent border, or taper the prim), or allow touching the prim behind the slider to activate the slider. If you drag something too small too fast your pointer can end up beyond the area of the widget and stop dragging it.

Thanks, Quistess! That work like a charm! I also add a larger slider knob with hidden parts so the mouse does not drag over it.

Now I have to relate the position of the slider with the value I want 🙂

Just as another idea, I once used a triangular prim with the top clipped off (because I couldn't be bothered with doing any fancy textures for it anyhow), which gave me a square "knob" and two tracks (the angled sides — which look flat because HUD), and then moved the "knob" my messing with the skew.

The shape math, and handling click position on the steeply angled faces, got slightly gnarly…  but not too bad, and neither was the result.  It also doesn't have the issue of sliding off the knob (except for sideways), and you could still just click the track to set a specific position.  All with one prim and no textures, because I've got the graphic artist skills of a turnip.  (You could probably handle a little sideways slip too, with a suitably distorted track texture.)

I use a few of them for things like the adjustable speed position joggers on a camera save and restore HUD I tossed together because sometimes you have just the right scenic view (honest!) in a club, but then you wanna have a quick look around the room…

Seem to be interesting but I have a hard time to visualized it; are you suggesting adjusting the size of a triangle prim to make a slider effect when you touch it?

A box prim with taper at x:0.85, y:0.0 and varying the top sheer between x:+/-0.45 would work. The math shouldn't be too too bad, but setting shape primitive params is a bit of a pain because you have to set all of them at once.
