Ich arbeite gerade an meinem ersten Jump'n Run Spiel. Der Anfangsteil funktioniert bereits ordentlich, aber ich bekomme immer noch einen "Bug", der erscheint, wenn sich meine "Colums" bewegen. Dies geschieht nur, wenn "MOVE_SPEED" 1 < ist. Ich habe es auch mit einem Timer versucht, dasselbe.Java Swing Rendering Phänomen in 2D Spiel
Dies ist, wie es aussieht:
Bitte werfen Sie einen Blick auf den Code:
...
public class Board implements Runnable, KeyListener {
JFrame frame;
ArrayList<Column> cList;

private boolean ingame = false;
public final static int INIT_WIDTH = 600;
public final static int INIT_HEIGHT = 400;

//When this is 1 the problem doesnt appear!
private final int GRAVITY = -3;

}
private void initBoard() {

}

cList.add(new Column(i + 1, true));
frame.add(cList.get(i));
}
}
private void initPlayer() {
p = new Player();
frame.add(p);
}
private void moveColums() {
for (Column col : cList) {
col.setLocation((int) (col.getLocation().getX() - MOVE_SPEED), 0);
}
}
private int playerStanding(double pX) {
for (int i = 0; i < 8; i++) {
if (cList.get(i).getX() <= pX
&& (cList.get(i).getX() + cList.get(i).getWidth()) >= pX) {

}
}
return -1;
}

// gravity

this.floorTop = cList.get(cPlayerStayingOn).floor.getY();
}
private void recycleColums() {
if (cList.get(0).getX() + cList.get(0).getWidth() <= 0) {
cList.remove(0);
cList.add(7, new Column(7 + 1, false));
frame.add(cList.get(7));
}
}

try {
Thread.sleep((lastLoopTime - System.nanoTime() + OPTIMAL_TIME)/1000000);
} catch (Exception e) {
}
}
}
}
}
und die Spalte Klasse:
...
public class Column extends JPanel {
JPanel floor;
JPanel grass;
Random rand = new Random();
private static final long serialVersionUID = 1L;
public final static int WIDTH = Board.WIDTH/6;
public final int HEIGHT = Board.HEIGHT;
private int position;
public final static int FLOOR_H = WIDTH;
public Column(int pos, boolean init) {
this.position = pos;
setBounds((WIDTH * position) - WIDTH, 0, WIDTH, HEIGHT);
setLayout(null);
setBackground(Color.WHITE);
floor = new JPanel();
floor.setLayout(null);
floor.setBackground(Color.BLACK);
if (init) {
floor.setBounds(0, HEIGHT - FLOOR_H, WIDTH, FLOOR_H);
} else {
floor.setBounds(0,
(HEIGHT - (FLOOR_H + (FLOOR_H * rand.nextInt(2)/2))),
WIDTH, FLOOR_H * 2);
}
grass = new JPanel();
grass.setBounds(0, 0, WIDTH, 10);
grass.setBackground(Color.GREEN);
floor.add(grass);
add(floor);
}
}
Irgendwelche Hinweise sind schätzen!

Was genau ist das Problem? Was ist der Fehler? Sollen die Spalten nicht da sein? – Slubberdegullion
das Problem sind diese kleinen Lücken zwischen meinen Spalten. (Ich habe sie mit blauen Pfeilen auf dem Bild markiert) – licklake
Also wenn du Spalten sagst, meinst du die schwarzen und grünen Fliesen/Land? – Slubberdegullion
