collision_start, Collision_end question

I have a flat peice that I would like to know when someone walks over it, i tried using the collision_start and collision_end to see when they are on it.. and have gotten off of it so it will send 2 messages.. one while they are on it.. one while they are off.

For some reason while your standing on the object it sends both events and spams the room until you get off of it. Any suggestions?


default {
collision_start(integer num_detected) {
llSay(0, llDetectedName(0) + " is on me";
}
collision_end(integer num_detected) {
llSay(0, llDetectedName(0) + " walked off of me";
}
}

I am very new to Collision events.. and the sl programming language, but read the wiki to mean that each one of these evens would fire one time, when the collision started.. and ended.. not 1,000,000 times until the colision ended.

In theory, yes, that should work. However, physics can be somewhat iffy in SL. Your best option would be to use llVolumeDetect.

use a list to manage this.

when collision_start happens search the list to see if that person is already on the object. if not add this persons key to the list (key_list += llDectedKey(i) my experience with volumedetect produced the same problem.

I've been having the same problem with collision_start. I was hoping that I wouldn't have to use lists and comparisons to get the behavior I wanted. But, it looks like this is the only way.

Thanks
