Description
! Event: touch_start( integer num_detected ){ ; }| 2 | Event ID |
Triggered by the start of agent clicking on task
| • integer | num_detected | – | Number of agents detected touching during the last clockcycle |
Caveats
Examples
You can use numbers 0 through num_detected - 1 to get detected agent keys: <lsl>default {
touch_start(integer num_detected)
{
integer i = 0;
for(; i<num_detected; ++i)
llWhisper(0, "Touched by " + llKey2Name(llDetectedKey(i)));
}

touch_start(integer nd)

llSay(0, "You just started touching me so I'm going to the other state...");
state other;

} state other {
touch_end(integer nd)
{

llSay(0, "The touch that brought you here just ended so I'm going back to default...");
state default;
