Particle Targeting - deadpool - 02-19-2013
How-to/Info:
•Copy paste the scripts below into new scripts inworld.
•Save it & then put them into separate objects (if not there already).
•Touch the object with the Give Key script.
•The Particle Script should now have it’s particle streaming towards the ‘Give Key’ object.
Give Key Script
PHP Code:
integer our_channel = -1212123;
default{
touch_start(integer total_number){
llSay(our_channel, "Key="+(string)llGetKey());
}
}
Particle Script
PHP Code:
//We listen on this channel for our target key
integer our_channel = -1212123;
//Message we listen for "Key=b31b25aa-de... etc". The = symbol being the seperator.
//Particle Params
