Pessoal, pesquisei na Net de descobrir que para trabalhar com game, é mais fácil usar o pacote GameCanvas, inclusive fiz uns exemplos q vi na net e funcionou no computador da facu, porém estou no meu trabalho e o mesmo exemplo dá um erro de io.exception, tenho instalado o wtk 2.2, midp 2.0 e cldc 1.1, já vi q o pacote está lá, mas qndo tendo carregar uma imagem aparece o erro, vide codigo…

// Method to Display Graphics
private void drawScreen(Graphics g) {

// display sprites
sprite.setPosition(currentX,currentY);
sprite.paint(g);
nonTransparentSprite.paint(g);
flushGraphics();
}
}
obrigado a todos q puderem ajudar…
