Dumb question but.... what is it called - multiple buttons/single prim face

Hi all, I have been seeing single prim gizmos with multiple buttons on a single side of a prim. I am not even sure how to search to find out how to do this. Can someone please give me the name of this functionality, and if possible point me to where i can find out more about how to do it? Thanks!!!

Hi StarSong.
I experimented after seeing an example in the College of Scripting and managed to create a prim with apparent separate buttons using llDetectedTouchUV function.

LOL i couldnt even figure out where to start.

I want to make a TP directory that will open the map llMapDestination.. need a dozen buttons but dont want to waste all those prims.

Hi, i came to the college of scripting but i cant seem to find that example, which floor would i find it on, do you know?

And when you're making the texture with all the buttons on, you may find some of the answers I received here /109/4a/331119/1.html of use. I certainly did!

The LSL function llDetectedTouchST () returns the coordinates of the point on the prim face where it was touched, and the function llDetectedTouchUV () returns the coordinates for the texture - which may be offset on the prim face.

The LSL portal () on the SL wiki should be your first port of call for technical information about the scripting language.

It's a fairly straightforward process. Think of a face of your prim as a grid with X and Y axes that go from 0 to 1, with the origin in the lower left corner. When you draw the texture to put on that face, it might help to actually mark off a grid in 0.05 units to use as an overlay layer while you're placing the buttons on the layer. Remember the corner coordinates (lower left and upper right) of each of your buttons.

Then, when you write the controlling script, use each button's coordinates as limits on if statements to activate some action. For example, if you have a button whose lower left corner is at (0.1,0.1) and whose upper right corner is at (0.3,0.45), you do something like this ...

touch_start(integer num_detected)
{
     vector Hit = llDetectedTouchUV(0);
     if (llDetectedTouchFace(0) == 1) //Ignore hits on any other face
     {
          if (0.1 < Hit.x & Hit.x < 0.3 & 0.1 < Hit.y & Hit.y < 0.45)
          {
              //Do something
          }
     }
}

ETA: I'm using llDetectedTouchUV in this example, because that way the touch coordinates are keyed to the texture and the buttons will still work properly even if I have to offset the texture on the prim face. You could use llDetectedTouchST instead, if you wanted to have coordinates keyed to positions on the prim, regardless of where the texture sits on it.

from the wiki http://wiki.secondlife.com/wiki/LlDetectedTouchST

//Sets a grid of x by y, in this case 144 squares and returns that number on touch.
 
float x=12.0;
float y=12.0;
integer Pos;
 
default{
 
    touch_start(integer total_number){
        if (llDetectedTouchFace(0) == -1)
            llOwnerSay("old client");
        else{
            vector pos = llDetectedTouchST(0);
            Pos = ((llFloor((pos.x*10)*x)/10)*(integer)y)+llCeil(pos.y*y);
            llOwnerSay((string)Pos);
        }
    }
}

Thanks to all who responded, I got it all up and working!
