Learning the Source Engine (Valve)

Well for the past few days, Jacob has been creating a game design document, and I've been looking at the Source Engine, and by looking, I of course mean changing the slightest thing and breaking it completely, and having to start over.

Right now I've a fairly good idea on how to modify some things now so hopefully things will only get easier from here on out. Though everything Jacob mentioned in the design document might be a bit hard to implement :P

Map Editor can now PLACE tiles :)

The map editor can now place tiles, of course its very limited at the moment. I still need to make basic tools to make tiling easier, such as a fill tool, rectangle fill, etc.

I'll probably omit the filename text in the corner for some basic brush types to select such as those said above.

All thats left after that is moving the view position (to make the map bigger than one screen) and saving/loading system.
