Tile type

[Limeoats]

There is currently no way to distinguish between different tile types (solid, not solid, ladder, etc). This is important so that we no longer need to use collision rectangles hand-drawn on each map. We can instead have solid blocks always be solid and the player will then always collide with them the same way.

I'm thinking a good way to implement this might be to be able to create different "Tile types" in a new editor window (create a new "Mode" for this. We can't have it in Tile mode because tiles are always drawing in tile mode). These tile types can be saved to the config file so that they are 100% dynamic. Dynamic is important so that I can still drop Lime2D into any game (platformer, top down, etc) and be able to create my own tile types without changing hard-coded types in Lime2D.
The user should also associate a color with each tile type. This will allow them to visually see what tile type is on each individual tile in the grid.

In this same window (brought up with some kind of hotkey), allow the user to select one of these custom tile types. When a tile type is "drawn" onto a tile in the grid, a little shape (triangle, maybe?) is drawn onto the tile on top of the image to represent that tile type. This is only visible when in Tile Type mode.

Finally, all of this information is saved into the XML at that particular tile location.
