[Unity] Increase performance (terrain generation)?

[as96]

15 minutes ago I came up with the idea of making a minecraft-like game, so I opened unity and wrote a simple script that generate a chunk of cubes, but of course as you may already figured it out that caused an extremely low frame rate:

How should I fix this?

(I thought of disabling the internal cubes but that is probably going to ruin the gameplay)

I never used unity but: textures?

What do you mean?

[Ciccioo]

it's totally unrelated to unity, but the only thing that i can think of is to make sure that cube sides are made of triangles, and not actual squares

maybe it was obvious already, but hey, that's my 2 cents

 

or you can merge the inner blocks (the ones we can't see directly) into bigger huge blocks, and then dinamically split them up in small blocks once they become visible or the player needs to break them

I guess I could replace 4 cubes of the same type with a single cube, and revert it when the player is able to see them, but still that doesn't looks like the best way to do it.

How does minecraft handle it?

Make sure you are only rendering visible faces.

 

How are you storing and traversing the blocks for rendering?

It starts a little slow but what you're looking for is in the 3rd or 4th video.

I'll just start over again, this time i'm going to do it in a better way  :unsure:

Look up instancing. You want the game to load 1 model (cube) and 1 texture (a run time or manually made large texture divided into grass, rock etc). From that you simply instance cubes and assign different UV values to different types.

You can write a class that encapsulate single instance and gives it e.g. drop or functionality, but that's once you get the FPS up.

Also read a thing or 2 about voxels, since that's what MC is based on.
