Summary

Function: vector llDetectedTouchBinormal( integer index );

341	Function ID
0.0	Forced Delay
10.0	Energy

Returns a vector that is the surface binormal (tangent to the surface) where the touch event was triggered.

• integer

index

–

Index of detection information

index does not support negative indexes. For the touch category of events only.

Specification

llDetected* functions only work if called from within Detection events (collision, collision_start, collision_end, sensor, touch, touch_start, touch_end) or in functions called by Detection events. They will fail silently and return unusable values if called during other events.

Caveats

• If index is out of bounds the script continues to execute without an error message.
• Events that enable the llDetected* functions always return at least one detected item.
  • Detection events are not raised if there is nothing detected.^[1]
  • The detection event's items detected parameter is initially never less than 1.^[2]ZERO_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 triggering event is not a touch event.
