黄金矿工小游戏为什么到达指定目标分数后不跳转下一关捏

黄金矿工小游戏一共设置了五关，第一关到达目标积分后不跳转第二关，时间结束后显示失败，比较源码十多遍了也不知道问题出在哪里，求指点

源码如下（源码state2是药水，state3是失败，state4是成功，我没有写药水，所以我的state2是失败，state3是成功）

设置断点跟，先看if到底进入没有，到底哪个变量的值不正确
如果进入了if，那么后面到底怎么运行的
我看你代码里直接写了个dispose，你是把当前窗体释放了吗

这玩意咋看 哦

if(Bg.count>=bg.goal)这里怎么Bg一会大写 一会小写，是不是有问题，另外没有全部代码不好判断，最好是文本代码

你直接把源码放到问题的代码块里，这样方便帮你debug查错，你这贴图片咋看呀
