How to code an AutoTiler (Easier than you think!)

Today we look at how I coded an AutoTiler for my base builder game Spruce - which is actually not that difficult. AutoTilers select the correct edge tile to render a blobmap of a specific tile type. Most engines like Unity and Godot support features just like this. To do something similar, we generate a bitmask based on tile neighbors and use that to look up the correct tile that we want to render.

I enjoyed the video, but i have just one question. How are you assigning which tile goes to what value? You have 16, 20, and 84. I can't say I quite understand it. Thanks for any help!

[@UnitOfTimeYT]

Hey. Glad you enjoyed it. I calculated those by doing the process that I described at 1:21
All you have to do is figure out which edges and corners should connect, set those to 1 in your 8-bit bitmask, and then get the resulting number. So for example, the 16 happens when only bit-position 4 is set. Hope that helps!

What's your emacs theme?

[@UnitOfTimeYT]

Hey! Right now I'm using tango-dark, and I use Source Code Pro as the font.

@@UnitOfTimeYT It would be great, if u went through your emacs config in a video.

Yeah I'd be happy to do that. I think a really old version of my init.el is here: github.com/unitoftime/config/blob/master/linux/init.el
It's in dire need of a cleanup though!
