Newbie & Debugging Questions
#1

How can i get a smooth way to get 2d voxel terrain(think minecraft 2d or terraria)?
thanks

Very, very broad question. What are you looking for specifically? What have you tried?

#3

You can use something like simplex noise to generate the height.

#4

I want the terrain to be like a dumbed down terraria. no caves and structures though
[EDIT]: side view

#5

Try this.

Thanks this really helped ;D

Simplex Noise is better than Perlin noise (in both speed and quality), but may be a bit trickier to understand. Hopefully that article explains it well enough. It also has source code at the bottom.

To use it:


double height =  SimplexNoise.noise(x/64.0, 0.0) * 64.0;

Then you simply convert height to an int, and fill the world with tiles from (x, bottomY) to (x, topY). (bottomY and topY being the limits of the world.)
