LibraryPreloadTextures

De DigiWiki.

So, textures load slow, and it's especially obvious when giving a presentation or showing pictures to your friends.

Here's an easy fix.

How do you use this script?

1) Drop it in a box.

2) Adjust the box size/shape to match your desire; the non-black face will be used for textures.

3) Drop in whatever pictures you like.

//--------------------------
// preloads textures on a box
// just drop it in with the images and it will cycle every 10 seconds, or change the picture_pace variable to change the speed
// updates on touch as well
//--------------------------
 
// Change this next line to adjust the image rotation speed
float picture_pace=10.0;

        pictures = llListSort( pictures, 1, TRUE ); // put them in order
