For the minimap tilemap, I want to make it so that there are walls at pixel positions. I want the player to be able to fire dirt and make land. I want the land to be stood on.

Ah, so a voxel type game!

This is a great goal. Unfortunately these are some of the most challenging types of games to do in normal game engines, and I don’t think tilemaps + minimaps will be performant enough for this today.

@Richard, @jwunderl, can you guys think of the easiest way to do this? The collision detection seems the hardest.

I kind-of did this in my ocean-jam game -

Writing a separate physics engine and plugging it in is going to be the best option for properly supporting this - the general purpose physics engine we default to has a few too many concessions to run efficiently for this sort of thing / needs to make different assumptions / limitations. I feel like Noita might have some dev logs for implementation I read before (or some game that I thought looked like Noita at least) that might be interesting for this sort of thing.

That was a very nice stream, but sadly I couldn’t make it :frowning:

For the record, if I couldn’t use Arcade then I would use Python on a computer or CircuitPython on hardware. But Arduino C still holds a special place in my heart because I started coding with it, no matter how annoying it is defining types and concating strings and adding semicolons everywhere and placing brackets everywhere and how cryptic the compile messages can be…but it’s insanely fast…


I think I did it!
