touch_start

Description

! Event: touch_start( integer num_detected ){ ; }

2	Event ID
	Delay

Triggered by the start of agent clicking on task

• integer

num_detected

–

Number of agents detected touching during the last clockcycle

Caveats

• When changing from a state that lacks a touch event into a state that has a touch event, the first touch will be dropped; this effects all three touch events (touch_start, touch, touch_end). See: SVC-3017

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)));
   }

}</lsl>

Notes

Do not change states from within the touch_start() event, since this will prevent the touch_end() event being called even if you did not define it. The perform state transitions use the touch_end() event instead!
