Hey,
I'm working on a project using gage2d. When I add more than 2 layers using a parallax, no error is thrown but the display stops updating.
simplified example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107
| import java.awt.Color; import java.awt.Graphics; import java.awt.GraphicsConfiguration; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Image; import java.awt.MediaTracker; import java.awt.Toolkit;
import javax.swing.JFrame; import javax.swing.JPanel;
import com.dnsalias.java.gage.map.Map; import com.dnsalias.java.gage.map.Parallax; import com.dnsalias.java.gage.map.TileManager;
public class test { Image tiles[] = new Image[1]; Map map1; Map map2; Map map3; Parallax parallax; JFrame frm;
public test(){ GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice gd = ge.getDefaultScreenDevice(); GraphicsConfiguration gc = gd.getDefaultConfiguration(); frm = new JFrame(gc); JPanel content = new JPanel(); content.setLayout(null); mPanel mPanel = new mPanel(); mPanel.setBounds(0,0,500,400); content.add(mPanel); frm.setContentPane(content); frm.setSize(640,480); frm.setTitle("Layer Test"); frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frm.setVisible(true); } public static void main(String[] args) { new test(); } private class mPanel extends JPanel { public mPanel(){ TileManager manager = new TileManager(64,64); map1 = new Map(manager, 20, 20, 500, 400); map2 = new Map(manager, 20, 20, 500, 400); map3 = new Map(manager, 20, 20, 500, 400); try{ tiles[0] = Toolkit.getDefaultToolkit().getImage(test.class.getResource("images/tile1.png")); MediaTracker m = new MediaTracker(frm); m.addImage(tiles[0], 0); m.waitForAll(); }catch(Exception e){ e.printStackTrace(); } int[] ids = new int[tiles.length]; for(int i=0; i<tiles.length; i++) ids[i] = manager.addTile(tiles[i]); int mapdata[] = new int[400]; int mapdata2[] = new int[400]; for (int i = 0; i < mapdata.length; i++){ mapdata[i] = 0; mapdata2[i] = 1; } map1.copyMap(mapdata); map2.copyMap(mapdata); map3.copyMap(mapdata2); } public void paint(Graphics g){ g.setColor(Color.white); parallax = new Parallax(); parallax.addMap(map1); parallax.addMap(map3); parallax.render(g); g.dispose(); } } } |
The above code adds a blank layer on the bottom, and a layer filled with "tile1.png" on top.
It works perfectly with 2 layers, but if you remove the comment on the line that says parallax.addMap(map2), nothing is displayed.
