Information:

It took time to get the code working correctly. This is rope mesh generator and spring mechanic.

Blender 4.4.x

Testing how node editor works. Trying to make simple as possible but the register and unregister has some bug to handle remove nodes.

Simple physics collision 3d.

Raylib 5.5

W,A,S,D = movement. Space = jump.

Notes:

• landing will off sets bug.

Ported to mineccraft clone base on javascript. https://www.youtube.com/watch?v=_aK-1L-GC6I&list=PLtzt35QOXmkKALLv9RzT8oGwN5qwmRjTo&index=5

simple collision detect but still need work. move around but input bugged a bit.
