Writing a fixed point collision system from scratch

[small carbon]

Current progress. following a tutorial, its pretty good. managed to get a pretty robust system for now!

added circles and stuff

Circles are the simplest collision systems right?

[small carbon]

theyre easy enough, the simplest is circle on circle

[lofty crater]

Yeah cuz its just distances pretty much

Impressive that you have iregular shapes as colliders

Will you add rotation?

[small carbon]

for what I'm doing? probably don't need to. all I need now is capsule colliders and static I think I'm done with the main part

alr

[small carbon]

added support for static and triggers as well as some background stuff!

I'm almost there, just struggling with contact point findng

[small carbon]

doing somewhat well, main issue is collision point solving now. seems to work most of the time

[small carbon]

fixed collision solving! my system is basically complete now! all i have to do now is write communication between collider entities and im chilling

Nice, very detailed

Looks good! What tutorial are you following?

I'm following this playlist, which is already written in C# so it makes it a lot easier to write with. All the other ones were written in C++ which didn't feel too good to read. I just replaced the floats and vector2's with my Fixed64 and FixVector2s and it came out basically identical 😄

Wow this is super in depth, thanks for sharing. Are you making it fixed point for determinism, maybe for multiplayer?
