java 坦克 打第一辆坦克没有爆炸效果

你提供的代码不完全，无法深入分析，但是照你说的有显示“进入画图”，那么，很可能if(g.drawImage(image1, b.x, b.y, 30, 30, this))这个返回值为false，我刚查了下API，它的返回值说明Returns:

false if the image pixels are still changing; true otherwise.另外这个方法有这么样的说明This method returns immediately in all cases, even if the entire image has not yet been scaled, dithered, and converted for the current output device. If the current output representation is not yet complete, then drawImage returns false. 也就是说，现行输出未完成，图像像素仍在变化的时候，你就调用了这方法，那么会返回false。你检查一下代码，在你调用这段代码前，你的初始化工作做好了没。另外，最好就是像1楼说的，把图画到一个bufferImage里，再把bufferImage画到屏幕上
