These set of scripts allow for a prim to act as a server and load textures onto unlinked prims. The main benefit is that the receiving prims have *no* scripts. This means that the server, which consists of three scripts can load onto 30 prims without needing 20 scripts. Please note there is a 3 second delay for each remote load. It's main use would be for billboards, although it could substitute some texture changers.
Directions:
Get the keys of the textures you want to use. Put them into both Remote Load Texture Display(input list).lsl and Main Display.lsl. Now decide on what number you want to use as your pin(you can leave the default of 606 if you choose). Set up the prims you want to use as billboards. Select which billboard you want to use as a server. Get the keys and set the pins for all the billboards except the server using Get key & set pin.lsl. Copy these keys into Remote Loader.lsl. Add Remote Loader.lsl to the server. Add Load Texture Display(input list).lsl to the server. Check Main Display.lsl parameters to make sure they are what you want and add that to the server. Enjoy=D.
Scripts:
There are 3 scripts that go in the server:
- Remote Loader.lsl which remotely loads the 'Remote Load Texture Display(input list).lsl' script.
- Remote Load Texture Display(input list).lsl which is remotely loaded and display the texture before deleting itself.
- Main Display.lsl which tells the remote loader when to load, and is the only active script most of the time.
Two other scripts are:
- Print inventory texture keys.lsl which prints the keys of inventory textures
- Get key & set pin.lsl which sets the remote load pin on prims and tells the owner the prim key.
