DunGen (GM)

"DunGen" is a grid-aligned tile-object-based dungeon generation prototype.
Here is a downloadable demo, and the source-code / project file.

Note: Feel free to use the source project for your own projects, credit appreciated.

No relation to the Unity Asset Store branded assetpack/project, this is based on my years-old, terribad system by the same name, which I used for DeadBasic: https://gamejolt.com/games/dungen-gamemaker-dungeon-prototype/13549 

The software and source project is provided "as is". My code isn't overly good. It uses GM's standard way of handling object instances to instantiate classes of dungeon tiles which can be referenced by the code.

It handles hallways, rooms, junctions and dead-ends. So far it does not feature doors, as I am still yet to determine how I am going to do that for my current project, I may add doors to this generator later.

If you want to turn the generated results into things later, some code after generation is complete would do the trick:

with obj_dg_hall_h { instance_change() }
That would, for example, change all horizontal hallways to whatever you declare.
