3D Physics Engine

[ShoesForClues]

I'm thinking either 1st person or 3rd person RPG dungeon crawler with this physics engine for combat and world movement.

An RPG dungeon crawler would be pretty awesome! If you do plan on making it, make sure to use the version from my GitHub since that's the one being constantly updated.

Sup y'all. Been working on a 3D physics engine for a while and finally made progress with this.

This engine uses a clipping algorithm that I came up with and does not rely on GJK/EPA or SAT. This does give the disadvantage of it only working with vertex shapes.

I'll release the source of this soon, once I clean up the code. It's not as stable and kinda laggy atm.

UPDATE: Here is the preview demo!

CONTROLS:

• Use WASDEQ and mouse buttons to move the camera
• Press [1] to toggle wireframe
• Press [2] to toggle bounding boxes
• Press [3] to pause the physics simulation and [T] to step through each frame
• Press [F] to fire an object
• Press [R] to move all objects

Apologies if the code is messy. Some of it dates back to 2 years ago!

Please also consider following my GitHub for updates: https://github.com/0x1ED1CE/FPS

Wow! This is impresive!

I was looking for a 3D physics engine in lua and this looks very good!

I'm a Unity developer, but I have an authoritative server written in lua and my aim is doing all physics calculation there and using Unity only as viewer, level designer and to collect input.

I also need the simulation to be deterministic, is your physics engine deterministic?

Hello what you did is very impressive truning a 2d engine to a 3d engine is madness but I am just here to say that I made it compatible with touch controls and can I share it here

Hey! Sorry for the late reply. As for your question, it should be as long as you're feeding it the exact same inputs. Though even that can have many variables at play. Such as floating point precision, clock resolution, etc.

Sure, feel free

Here is the touch control compatible version then
D-pad to move
A down
B up
X summon a phisics object
Y grab
And I couldn't add the rest of the buttons because I ran out of them I could use the new version of my buttons library that allows you to add as much buttons as you want but I didn't want to change the code too much

Also there are some bugs with the size of the buttons I don't know why it's happening in my phone it's fine but in higher resolutions it's a bit unusable and the scrolling is a bit bizarre when you press multiple buttons at once because it uses mousemoved and this one tracks only the first touch
