User:Lum Pfohl/LSL Goodies/LumVision Presentation Script v0.2
LumVision Presentation Script v0.2This is my script for an in-world slide show. Rez a cube and fill it with textures followed by this script. If the textures are named to be sequential, this presentations script will display each texture in that order. Touch the cube to start. A drop down menu will provide options to go back, go forward in the sequence of textures, or reset the script. <lsl>// // LumVision-Presentation Script v 0.2 // // Written by Lum Pfohl December 11, 2007 // // January 02, 2008 - Added code to precache the next texture after a short time delay
