lab aktiviti lagi yooo...

ini kelas Sprite sobat :

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;

public class ContohSprite1 extends MIDlet {
private Display display;
public void startApp() {
try {

display.setCurrent(gameCanvas);
} catch (Exception ex) {System.out.println(ex); }
}
public Display getDisplay() {
return display;
}
public void pauseApp() {}
public void destroyApp(boolean unconditional) { }
public void exit() {
destroyApp(false);
notifyDestroyed();
}
class ContohGameCanvas extends GameCanvas implements Runnable {

try{

}catch (Exception ioex) { System.out.println(ioex); }

}
// membuat otomatis start thread untuk game yang berulang-ulang(loop)

}
public void stop() { isPlay = false; }
// Main Game Loop
public void run() {

while (isPlay == true) {

drawScreen(g);
try { Thread.sleep(delay); }
catch (InterruptedException ie) {}
}
}
// Method untuk menghandle inputan dari keypad
private void input() {
int keyStates = getKeyStates();
//sprite.setFrame(0);
// Ke Kiri
if ((keyStates ==4)){//& LEFT_PRESSED) != 0) {

}
// Ke Kanan
else if ((keyStates == 32))//& RIGHT_PRESSED) !=0 )

sprite.setFrame(3);
}
// Ke Atas
if ((keyStates == 2)){//{ UP_PRESSED) != 0) {
currentY = currentY - 1;
sprite.setFrame(2);
}
// Ke Bawah
else if ((keyStates == 64))//& DOWN_PRESSED) !=0)
if ( currentY + 10 <>
currentY = currentY + 1;
sprite.setFrame(4);
}
}
// Method untuk Display Graphics
private void drawScreen(Graphics g) {
//g.setColor(0xffffff);
g.setColor(228,77,3);
g.fillRect(0, 0, getWidth(), getHeight());
g.setColor(0x0000ff);
// display untuk sprites
sprite.setPosition(currentX,currentY);
sprite.paint(g);
nonTransparentSprite.paint(g);
flushGraphics();
}
}
}

selamat mencoba sobat!!!
