我对这个我正在制作的游戏有一些疑问......
首先，当我按F使坦克开火时，weapon_explosion.zip的图像全部放在一起，造成大量滞后。
第二，在我解决了很多错误之后： 再次射击使子弹再次朝同一方向发展。 子弹加速到极高的速度？ （爆炸滞后）
第三：
如何制作.zip动画一次，我只是在约2.5秒后摧毁它
现在，这是我的代码：

另外，我的Builder.load_string s：
root = Builder.load_string('''

allow_stretch: True
keep_ratio: True
pos:(0,130)
''')
runTouchApp(root)
另一个我不完全理解的......（来自别人。）
Builder.load_string('''
<PlayerImage>:
canvas.before:
PushMatrix
canvas.after:
PopMatrix
''')
答案 0 :(得分：0)
我需要在self.eventr取消预定movebullet(self):。
Clock.unschedule(self.eventr)
