Summary

Function: vector llDetectedTouchBinormal( integer index );
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.
  • The touch has moved off the surface of the prim.
  • The triggering event is not a touch event.

Footnotes

  1. ^ The exception is no_sensor but it doesn't enable llDetected* functions.
  2. ^ Like all event parameters, the user can overwrite the initial value.
