Summary

Function: llPassTouches( integer pass );

Sets pass-touches prim attribute.

• integer pass – boolean, if TRUE, touches are passed from children on to parents

The default is TRUE if there is no script to handle the touch events.

Caveats

This has no effect (whether set TRUE or FALSE) from the root. Touches are always passed to the parent when there is no touch event script in the child, even if this is set (TRUE or FALSE) within another event in a child's script. If you want to block touches from a child by using this function, you must add a script with a touch event in the child and set to FALSE.
