今晚刚刚下载的gamemaker,按照软件给的示例操作时最后出了一点问题：让炸弹的数目每隔一定时间增加一个，结果我设置了以后（就是那个creat ininstance）后运行时候发现每隔一定时间时间都是数目乘2，最后全屏都是了。现在不知道怎么改成每隔一定时间只增加一个。。。求助啊

还有后期如何进行游戏改进呢

大神们呢

Creating Bombs
To make the game more difficult we want to create additional bombs while playing the game. We can create a new object to do this but we can as well use the music object for this. So reopen the music object by double clicking on it in the list at the left.
是的你没看错，教程上要求的是用obj_music来完成这个动作。具体原因，上边我也说过了。
