I need some help!

[psichill]

Okay I need some help with an NPC.
I am trying to make it where, when you walk onto it it lights up but when you walk off the lights turn off.

Here was my attempt!

// NPC made by Ramsey
if (created) {
setimg whatever.gif;
dontblock;
drawunderplayer;
}
//#CLIENTSIDE
if (playertouchsme) {
setcoloreffect 1,1,1,0.99;
drawaslight;
sleep 1;
}
