Summary
Function: vector llDetectedTouchUV( integer index );| 337 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a vector that is the texture coordinates for where the prim was touched. The x & y vector positions contain the u & v face coordinates respectively (<u, v, 0.0>).
TOUCH_INVALID_TEXCOORD is returned when the touch UV coordinates cannot be determined. See Caveats for further details.
| • integer | index | – | Index of detection information |
index does not support negative indexes. For the touch category of events only.
Caveats
- If index is out of bounds the script continues to execute without an error message.TOUCH_INVALID_TEXCOORD is returned when...
- The avatar's viewer does not support face touch detection.
- To check if face touch detection is supported check the return of llDetectedTouchFace.
- The touch has moved off the surface of the prim.
- The touch happened too close to the edge of the face to determine a location.
- The triggering event is not a touch event.
Examples
<lsl> default {
touch_start(integer UV_detected)
{
integer i = 0;
for(; i<UV_detected; ++i)
llWhisper(0, "UV clicked: " + (string)llDetectedTouchUV(i));
}
