==Simple Stupid Slide Show==
 
Dumb slide show: simply rez a cube, throw in the script and textures and instant slide show.  Ya, boring isn't it?

==SLURL Raster Image URL Generator==
 
I was rather interested in the raster images provided within SL and SLURL.com so I decided to figure out how to replicate it in such a way that it could be incorporated into tools and/or services outside the standard fair offered by Linden Labs.
 
 
 
<lsl>
 
string MapTileURL()
 
 
    vector TilePos = llGetRegionCorner();
 
 
    //tiles are in a grid based on the regions, so 256m = 1 tile
 
    TilePos /= 256.0;
 
   
 
    //offset provided in the javascript, really 1278 + 1 (probably 0 -> 1 index difference?)
 
    TilePos.y = 1279.0 - TilePos.y;
 
   
 
    //should look like http://secondlife.com/apps/mapapi/grid/map_image/x-y-zoom-0
 
    string mapURL = "http://secondlife.com/apps/mapapi/grid/map_image/";
 
    mapURL += (string) llFloor(TilePos.x);
 
    mapURL += "-";
 
    mapURL += (string) llFloor(TilePos.y);
 
 
    //the 3rd value is something to do with zoom
 
    mapURL += "-1-0";
 
    return mapURL;
 
}

For all intentions this is a dumping ground of information that might be useful. All the information found here is free to use however you wish with no limitations.


Projects Description
Apocalypse HUD A modular tool designed to reduce code reproduction and provide the shortest path available for a given task. Thus it is fast and highly scalable by design.
n2k.AppSpot A project aiming to make a name2key and key2name service via Google's App Engine that utilizes the Second Life Search rather than storing keys within a database.


Scripts Description
Simple Slide Show Throw in the textures and it will automatically rotate through them.
Map Tile URL An LSL function that returns a string containing the current regions tile URL
