我几乎完成了这个Java游戏项目。我只需要在主角的包里增加一个被击败的敌人的钱。如果它们比主角的武器和盔甲更好,我还必须添加武器和盔甲。如何将敌人的钱加到主角的钱上?在我看来,main_ch.getBag()。getMoney()= main_ch.getBag()。getMoney()+敌人[selected] .getBag()。getMoney();应该可以,但是不能。

这是我的主要课程:

最佳答案

您正在调用一个访问器方法,就像它也会设置一样,但没有设置。尝试这样的事情:

main_ch.getBag().setMoney(main_ch.getBag().getMoney() + enemies[selected].getBag().getMoney());
