I've been searching the forums to no avail: is there any way to find out where on a prim I clicked? I haven't even found people asking similar questions.
I'm working on a HUD for a color-changing avatar, and I'd like to have a color wheel as well as a handful of preset buttons. I figure I could put a circular rainbow texture on a disc, then do some math to change a click coordinate into a HSV value that roughly corresponds to the color under the click.
If not, well, I'll just have a larger selection of color presets...

It takes some work but you can use llDetectedGrab()

Hmm, I was getting the same results from llDetectedGrab() no matter where I clicked on my test prim, aside from some seemingly-random fluctuations in Z. Maybe I'll just stick with a handful of predefined colors after all...

Building a menu system around it isnt that difficult |

You have to click, hold down the mouse button, drag the mouse and then release it. Also llDetectedGrap only works with touch, not touch_start or touch_end. _____________________

Hmm. I think that hacking around this is a lot more work than I'm willing to take on. Especially since it seems to only work when you <i>drag</i> the pointer, rather than just click. I'll think about alternative visual displays. Thanks for the suggestions and pointers, though!

There doesn't seem to be a way to get exactly where on the prim the click was placed (there's some projects which use sort of prim grid overlaid over larger surface to determine the spot clicked on that larger surface with some precision and couple of clicks, but that's still work-arounds) Perhaps it'd be simpler to just convert your colour wheel into 6 buttons the user could click to finetune colour values picked from provided presets... o.O |
