August 31st, 2008My Free Tileset, version 2

Second version of the my free tileset. Now is possible to build a entire house.

Here is the tileset.

There’s a nice map editor with several features called Tiled. If you are edditing game maps, take a look.

August 30th, 2008My Free Tileset, version 1

Although everything I do is under the license Creative Commons Attribution Share-Alike, I’m starting to group my pixelarts works and release them in single files under the GPL.

Here the first and small release:

In summary: you can use them freely for open source or proprietary, games or prototypes, professionals or beginners developers, for study or for lucrative purposes, whatever you want. You don’t need even ask me for that, just use it (but I appreciate a reference). You can even modify them as long you also maintain the same freedom for the derivative work. For complete details, read the GPL or ask your questions in the commentaries.

If you are looking for a free, big and great tileset, look the wonderfull work of The Mana Word project (both code and art under GPL).

Soon I’ll group others pixel art drawings of others games I made in a single tileset file.

If you have a similar work in a compatible license we can make release of them togheter and create a big free tileset.

April 27th, 2008Simple Java Tileset Example

Tilesets are a common technique in game development to create all kinds of tile-based games (from strategy to RPG games).

Here’s a example of simple 2D isometric square tilesets. I decided to use 32×32 pixels tiles and store 10 tiles per row in a single image:

I created a class called public class JGameCanvas that extends from JPanel from swing:

package game;
 
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import javax.swing.JPanel;
 
enum Tile {
GRASS, GRASS_STONE, GRASS_BAGS, T3, T4, T5, T6, T7, T8, T9,
TREE, TREE_CHOMP, TREE_DEAD, T13, T14, T15, T16, T17, T18, T19,
ROAD_H, ROAD_V, ROAD_HV_DOWN, ROAD_HV_UP, ROAD_VH_RIGHT, ROAD_VH_LEFT, ROAD_CROSS, T27, T28, T29,
WALL, WALL_POSTER, WALL_END_RIGHT, WALL_END_LEFT, T34, T35, T36, T37, T38, T39,
T40, T41, T42, T43, T44, T45, T46, T47, T48, T49,
NEWS, T51,      RES_1, RES_2, BUSS_1, BUSS_2, HOSP_1, HOSP_2, MARK_1, MARK_2,
PIZZ_1, PIZZ_2, RES_3, RES_4, BUSS_3, BUSS_4, HOSP_3, HOSP_4, MARK_3, MARK_4,
PIZZ_3, PIZZ_4, RES_5, RES_6, BUSS_5, BUSS_6, HOSP_5, HOSP_6, MARK_5, MARK_6
}
 
public class JGameCanvas extends JPanel{
    private static final int tW = 32; // tile width
    private static final int tH = 32; // tile height
    private static final Tile map[][] =
    {{Tile.TREE,Tile.TREE, Tile.TREE, Tile.ROAD_V, Tile.GRASS, Tile.TREE, Tile.TREE_DEAD, Tile.GRASS_STONE, Tile.TREE, Tile.TREE},
     {Tile.WALL, Tile.WALL_POSTER, Tile.WALL_END_RIGHT , Tile.ROAD_V, Tile.WALL_END_LEFT, Tile.WALL, Tile.WALL_END_RIGHT, Tile.TREE_CHOMP, Tile.GRASS_STONE, Tile.GRASS_STONE},
     {Tile.GRASS,Tile.GRASS, Tile.GRASS_STONE, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS},
     {Tile.PIZZ_1,Tile.PIZZ_2, Tile.GRASS, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS},
     {Tile.PIZZ_3,Tile.PIZZ_4, Tile.GRASS, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.MARK_1, Tile.MARK_2, Tile.HOSP_1, Tile.HOSP_2},
     {Tile.ROAD_H,Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_VH_LEFT, Tile.TREE, Tile.TREE_DEAD, Tile.MARK_3, Tile.MARK_4, Tile.HOSP_3, Tile.HOSP_4},
     {Tile.GRASS,Tile.BUSS_1, Tile.BUSS_2, Tile.ROAD_V, Tile.TREE, Tile.NEWS, Tile.MARK_5, Tile.MARK_6, Tile.HOSP_5, Tile.HOSP_6},
     {Tile.GRASS,Tile.BUSS_3, Tile.BUSS_4, Tile.ROAD_VH_RIGHT, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H, Tile.ROAD_H},
     {Tile.GRASS,Tile.BUSS_5, Tile.BUSS_6, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS},
     {Tile.GRASS,Tile.GRASS, Tile.GRASS, Tile.ROAD_V, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS, Tile.GRASS}
    };
 
    private Image tileset;
 
    public JGameCanvas() {
        tileset = Toolkit.getDefaultToolkit().getImage(this.getClass().getResource("resources/tileset.png"));
    }
 
    @Override
    protected void paintComponent(Graphics g) {
        g.setColor(Color.black);
        g.fillRect(0, 0, getWidth(), getHeight());
 
        for(int i=0;i&lt;10;i++)
            for(int j=0;j&lt;10;j++)
                drawTile(g, map[j][i], i*tW,j*tH);
    }
 
    protected void drawTile(Graphics g, Tile t, int x, int y){
        // map Tile from the tileset
        int mx = t.ordinal()%10;
        int my = t.ordinal()/10;
        g.drawImage(tileset, x, y, x+tW, y+tH,
                mx*tW, my*tH,  mx*tW+tW, my*tH+tH, this);
    }
}
