Tiled Terrain Editor update

Greetings,

Apologies for taking so long at this, available time has not been good and I’ve been doing a lot of experimenting and learning as I go. So far I have Image tile generation running and the menu system for the rest of it going.

I’ve uploaded the current code state to a new svn repository here:

https://code.google.com/p/radanz-game-code/source/browse/#svn/TiledTerrainEditor

You’ll need the library pngj added to the jMonkeyEngine SDK to compile it or download the compiled dist.zip file here

So far the menu works but the only real function working is: “Generate New Terrain” > “From HeightMap Image” > load any 16-bit Gray-scale PNG image > “Generate” > “Create Image Tiles”.

Only 16-bit Gray-scale png images are supported at the moment, any size, I have two test maps, one small at 1024*1024 and one very large at 8192*8192. The image is loaded one strip of tiles at a time so very large maps can be processed with exceeding memory requirements.

You can choose how many tiles to generate in both directions and the base image map will be scaled and interpolated as required, both bigger and smaller. Number of tiles is 8 minimum to 4096 maximum in each direction. Tile size selectable from 256 to 2048. PNG images will then be created and saved into the selected location under a new directory of the entered name (optional) with the file name: tilexxxxyyyy.png

Not much use for my terraintiler library at this stage but those who use jMe’s TerrainGrid will be able to use the generated tiles right away. Code to load the tiles like this:

        assetManager.registerLocator("path/to/tiles", FileLocator.class);
        this.terrain = new TerrainGrid("terrain", 65, 513, 
                           new ImageTileLoader(assetManager, new Namer() {

            public String getName(int x, int y) {
                String fileName = String.format("tile%04d%04d.png", x, y);
                return fileName;
            }
        }));

Next I’ll be working on the ‘j3o’ tile generation for my terraintiler library using textures that can be loaded on the generation screen. More on that later.

Any comments of the code so far would be very appreciated.

Cheers.

MapGenerator Menu

Quick update,

Have managed to load a large height-map image and generate a “mini-map” of it and setup the map generation menu:

MapGenerator

 

As the screenshot shows, the original file is 8192×8192 pixels, in 16-bit gray-scale.

Also populated drop-down boxes to select the “world” size in tiles across and the size of each tile, also there is a list to set the maximum height of the generated world. All in “world units”

Next is to link the drop down boxes to change the “pixels to unit” scale value and also to lock the sliders on the left to keep each one less than the one below it (they are there to set the height percentage for painting the one to four textures based on the terrains height during tile generation)

Cheers

TiledTerrain Editor

Hi all.

Some visible progress on the terrain editor program, after bitching with Nifty-Gui I think I’m getting the hang of it. just piecing the menus together and adding code functions to them, once they’re all done the real work can begin.

Here’s some screenshots so far:

File Loading screen for loading tilesets or images/textures:

java 2013-07-11 20-57-06-23

 

The tile-set generator screen (left image pairs for initial height-based textures are diffuse&normal pairs, large right-hand image will show a scaled version of the users heightmap image):
java 2013-07-11 20-57-22-60Until next update!

Cheers.
