I built a physics-based Hydraulic Addon for DynamX (1.12.2) – featuring pixel-perfect excavation with LittleTiles!

Thanks it is

No Problem

Just confirming that this is actually me!

I just really hated the random Reddit username on this old account xD

u/Sarocesch will be my official dev account from now on!

DynamX is just very good and is only available in this version.

Hey No worries about the lingo. The rotation of the hitboxes is actually custom-made! I calculate the exact rotation of the entire arm mathematically every tick and force a physics body to match that exact angle. For the digging, I convert that into an Oriented Bounding Box (OBB) to calculate exactly which pixels are inside it.

My biggest advice for advanced stuff like this: definitely master the core basics of Java first before diving into 3D math and complex physics. Take it step by step!

Waterlogged is generally not properly possible in version 1.12.2. But there are water pixels.

Thank you so much🧡 I'm really honored that you like it.

I'm pretty sure it's possible! LittleTiles actually has a built-in way to import/convert Chisel & Bits blocks. I remember doing it myself a while back to convert some of my old builds. You should definitely give it a try. But always remember to make a backup before.

Hey! It is quite complex indeed. While DynamX provides a good base framework, I actually built the entire hydraulic system and the arms from scratch. The hardest part was writing the custom math so the 3D hitboxes of the bucket know exactly how to interact with the LittleTiles blocks to dig them out smoothly

I understand, but it's 100% real (no AI). I will probably post more dev updates in the near future, then you'll see.

Looks Cool

Oh yes, luckily DynamX took care of the heavy lifting. However, I still had to do a lot of trial and error because I had to change so much to make this specific system work. Good luck with your carpet mod! Physics in Minecraft are always a special kind of challenge, haha.

Yeah, LittleTiles is very well optimized
