Function: vector llDetectedTouchBinormal( integer index );

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

• integer

–

Index of detection information

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

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.

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]
