how to create an 2d block-world?

Thanks micha. It is possible, that there are less caves, not smaller only less? Beause when I generate a world with 50% caves, it looks little stranges...
And the seed of love.math.noise can't work, it has no seed. Can I anywhere else set the seed of love.math.noise?

the value(s) you pass into love.math.noise() are the seed:

Code: Select all

local w, h = 100, 100
local world = {}
for x = 1, w, 1 do
    world[x] = {}
    for y = 1, h, 1 do
        world[x][y] = love.math.noise(x, y)
    end
end

And as for less caves, that was the threshold micha was talking about. You can then increase the scale, otherwise the caves would become smaller as well.

I think I understood this.

I updated my demo a bit, so you can play around with the values.
Press up/down/left/right to change the scale of the noise (similar to zooming in and out)
Press w/s to change the threshold value (=ratio of green to blue blocks)
Press a/d to change the seed.

Edit: Press space to set x-scale and y-scale to the same value.

As the others pointed out already, love.math.noise does not have a random seed. What I did instead is added a third argument to the function call. That means that in reality I use a three-dimensional noise, but fix one of the three values. That way I get a two-dimensional noise and I can use the third value as a seed.
