repetive world

[PJani]

recently I started thinking how to make world like sphere, where you allways point with feet to center of gravity force and in the same time make world feel like it is flat, but still round, like planets. so I brainstormed and I tought what if I make flat world which would repeat each time I make full 360 round the fake planet.
Anyway how would be this possible in newton to implement? so when object goes past boundery of world it jumps to another side, without any hickups of joints or speed, interia loss. any idea?

Why not Just use an actual sphere-shaped world? it would work pretty OK, except that your world artists would want to stab you in the face

You could also use traditional world and segment it to wrap around.

Huh i considered that but, my world is actually made out of blocks(no i am not making MC clone... ) so sphere would work if there was no blocks or "sharp" edges.

You can apply spherical mapping projection to the cubes aswell, maybe something like this, but this is hex grid based:



edit: i did a bit googling for you, there's a healpix cube to sphere projection:


there's also several others, this is a good place to start:

I suggest you build world out of slightly curved hex cube pieces, and then arrange them as a sphere, that sounds like the best method to me.

Ej hvala . Thank you! I didn't expect such comprehensive answer and so fast . I will look in to it.
