For my pet shop on TOT I made one. Im willing to give the code away. no big secret or nutting. its just common sence really..
NPC Code:
if (created) {
this.x = 32 //X position of the light
this.y = 35 // Y position of the light
showimg 0,light2.png,this.x,this.y;
changeimgcolors 0,1,.89,.38,.99;
changeimgvis 0,1;
changeimgpart 0,48,0,32,64;
}
The only reason I didnt putt he #s directly on the showimg is so you could see where the X and y should go... That basicially it. not much work.
