Summary
Function: vector llDetectedTouchPos( integer index );| 339 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a vector that is the position where the object was touched in region coordinates, unless it is attached to the HUD, in which case it returns the position relative to the attach point.
| • integer | index | – | Index of detection information |
index does not support negative indexes. For the touch category of events only. The prim that was touched may not be the prim receiving the event, use llDetectedLinkNumber to check for this; likewise you can use llDetectedTouchFace to determine which face was touched.
Caveats
- HUD attachments currently return coordinates relative to the center of the screen rather than the attachment point. SVC-3425
- If index is out of bounds the script continues to execute without an error message.
- TOUCH_INVALID_VECTOR 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 event triggered is not a touch event.
- The avatar's viewer does not support face touch detection.
