This here is my first time making a map tile collission function for 2D platformers.

My goal is to make a set of collission functions robust enough that I won't have to make new code ever again. Foolish as this may be it's a good exercise.

This version (v0.1.1) features speed-proofed collissions with solid terrain via map tiles, using flags 0 to 4 to indicate the size of the collission.

Feel free to use any parts of my code you fins useful. Making collission code is horrible and if I save someone else from having to make their own that'd be fantastic.

I have tried to comment the code thoroughly.

Please do contact me if you have any issues, doubts, criticisms, or advice.

In the future I intend to add semi-solid platforms, code for collissions between non-map-tile entities, code for standing on and being carried by moving platforms, and possibly even slopes and water or quicksand-like terrain. But for now, simple solid terrain of full and partial tiles works, and I am very happy with that.

This is basically a half-assed demake of Wingnuts tmporal navigator, and my first time coding ever. YIPPIEEE!
(The time I did the first steps to a javascript course on codecamp does not count ahahaheh)

If you look at my code you will find Some Horrors Indeed. Once I figured out how to have multiple bullets exist at once I went "okay let's try to make everything else with just what I now know" as a personal challenge.
I was advised to use voids, inverse functions for sin and cos, atan... and I am sure all of those suggestions were good, but I wanted to figure out if I could get enemies to target me without any of that.

The result is code that works well enough and I don't wanna look at ever again in my life, WOOHOO! I'll take it for my first project eheheh.

Pico-8 is lovely butI think I am done with it now. Now I wanna try TIC 80 just to see how different it is, and after that? I might jump to picotron. I can see myself making a new Splash baddies on picotron, with less terrible code, a radar that doesn't cover up the whole screen, clouds... yeh... but for now I have to take a step back from gamedev, I've got other hobbies and ArtFight is just around the corner!

Many thanks to everyone who has played and commented on this, both during and after its development, the pico-8 community has given me avery warm welcome! <3
