//Name: Simple Texture Changer (input list)(multiple prims & multiple side).lsl //Purpose: To change the texture on certain prims on certain sides of a linked set. //Technical Overview: The script finds how many textures there are in the input list, and uses a timer to change the // texture on a side based on randomness or order. It changes all sides of the certain prim to the // specified texture //Description: A simple texture changer script that changes the texture on certain sides of certain prims in a linked // set to those in the input list. It allows for a random order, or a logical "next up" order. //Directions: Create a prim. Place the script in prim inventory. Modify the script parameters to suit your needs and // save.

//Compatible: Mono & LSL compatible //Other items required: None. //Notes: Uses a timer event. Should be low lag. Commented for easier following. ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

   "00000000-0000-0000-0000-0000e0000000"];//put your texture UUIDs/keys in here

//Please note there is a .2 second delay between prims. //"prim number, side number, side number...side number" //-1 equals all sides for that prim list sides = [

   "0,1,2,5",
   "1,3,4,1"];//put in which sides you want the texture to be changed on.
