This is tool for making isometric maps. It uses a series of arrays for stroring data about each tile and then draws those tiles in a specified order.

Each tile is identified by an a and b cooridinate. The a axis runs up the left upper side, the b axis runs down the left lower side.

The position of each tile is determined by the dX, dY, and dZ variables. These are the width of a tile, heighth of a tile, and heighth of a cliff respectively, and are constant.

Right now, the tile graphics and height are editable. Editing them currently requries writing your own set of array values.


It took me three weeks to get all the equations worked out, I'm hoping the rest comes along more quickly. I want to make a GUI map editor so people don't have to type all that tile data. I included two sets of tile graphics, you can make your own if you use my templates. I have the scripts partially commented, but the commands in the object are not. Remember, this is version 0.1, it will get better. And if you use this, please give me credit, I was 15 minutes late for calc III this morning while figuring out the equations.


EDIT: The .zip can be found HERE, RAR IS BELOW.

EDIT 2: I've got it up to version 0.2. I have implement objects, specifically a rock. I also have a primitive map editor. It saves a file to the same folder the game is in with all the map data. You have to open that file with notepad and copy the data into a script in GM. I'm still working on that, but at least with the external file, you can send the map over the internet. I made a map using the editor to replace the first one I made. The editor is in room1, the map is in room0.

Edit 3: I have added a cursor that you can move with the arrow keys, and I have made it possible to rotate the map in 90 degree increments using page up and page down. I have also added transparent tiles to make holes in the maps. However, I have abandonded commenting for now, as the code is getting more complicated and so are my classes, when I get more time, I'll try to clean things up and write some comments.
