Empty Height Map Implementation

Contribution Depot

Would anyone be horribly offended if I committed this? Its a very simple height map implementation that just builds an array of 0’s so that flat terrain can be quickly achieved… Good for debugging, I figure this would be useful for people working on their own tile loaders or just want flat, endless terrain :slight_smile:



[java]

import com.jme3.terrain.heightmap.AbstractHeightMap;



/**

  • Creates a flat heightmap of a desired size.
  • @author Skye Book

    *

    */

    public class EmptyHeightMap extends AbstractHeightMap {



    private int size;



    /**

    *

    /

    public EmptyHeightMap(int size) {

    this.size = size;

    }



    /     (non-Javadoc)
  • @see com.jme3.terrain.heightmap.HeightMap#load()

    /

    @Override

    public boolean load() {

    heightData = new float[size    size];



    for(int i=0; i<(size*size); i++){

    heightData=0f;

    }



    return true;

    }



    }

    [/java]

You can just pass in a float array of zeros directly to the terrain quad constructor if you want it flat, without having to use a heightmap. The heightmaps just are a converter from various data sources to height values using the heightmap.getHeightMap() method.



Also if you do not supply an array to the constructor, it will create an empty/flat heightmap for you.

Ah, excellent!



Gonna have a look at the source now :slight_smile:



Edit: Well played, @sploreg… well played.
