The title of the topic says its needed to understand what i want, but if it isnt enough for you what i want is a script or a system that can allow me to have more that the 7 autotiles you can have each map.
I don't think a script can do that; it's a limitation of the engine. I suppose I could be wrong. Why would you ever need more than 7 autotiles per map, though?
You can't add extra autotiles to the autotiles section of the tileset but you might be able to look at either game map or spriteset map to add 1
I found a script by SephirothSpawn, it allowed more autotiles. However I believe it took a lot of configuration or something because you can't actually just map it on there.
Only way I can think to get past the auto-tile problem would take A LOT of config. You could probably create a script that changes the auto-tile bitmap while the tileset is being made, but that would require you to set up the x, y, and bitmap for every tile that you want to use it for. This would be god-awful, so not worth it, and extremely tedious to setup for a single map, let alone multiple ones.
My best suggestion would just to work with the seven. In my experience I have never needed more than seven.
