Simple slideshow projector

Another one from my series of LSL training courses.

Touches to switch to the next texture; resets if textures are added or removed to the inventory.

integer numberTextures = 0;
integer currentTexture = 0;
default
{
state_entry()
{
numberTextures = llGetInventoryNumber(INVENTORY_TEXTURE);
}
touch_start(integer who)
{
llSetTexture(llGetInventoryName(INVENTORY_TEXTURE, currentTexture), ALL_SIDES);
if (currentTexture < numberTextures -1)
currentTexture++;
else
currentTexture = 0;
}
changed(integer what)
{
if (what & CHANGED_INVENTORY)
llResetScript();
}
}
