}问题如下:
当我打第一个坦克时,没有爆炸效果,第二个第三个才有那里出了问题,请详细指教!!!
如果没看到效果,推测有可能跟爆炸图片由于需要加载图片的时间赶不上线程运行的速度,导致图片来不及显示有关,第二次爆炸由于图片已经加载所以没有问题。
你可以在游戏开始前在某个不可见的地方draw一下这几个Image,就可以验证是否这个问题。另外
if(bom.life==6)
{
g.drawImage(image1, bom.x, bom.y, 30, 30, this);
}else if(bom.life == 3)
{
g.drawImage(image3, bom.x, bom.y, 30, 30, this);
}else
{
g.drawImage(image3, bom.x, bom.y, 30, 30, this);
}
肯定有问题,image2没用上hittank()中的switch也有问题,由于没使用break语句,导致一次击中可能产生两个炸弹
