首先历遍了所有的箱子

for(const b of world.querySelectorAll('.箱子')){
    b.inbox = {'喵子弹':0,'喵子弹':0,'医疗包':0,'手雷':0}
    b.enableInteract = true
    b.interactRadius = 2
    b.interactHint = '箱子'
}

随后就开始搞交互了……

b.inbox['喵子弹'] += selection

出错了）））））））

问题在哪里呢~

+=

+=会直接成为这样：

原本0喵子弹，加上100和1喵子弹就是（）

真不错）））

我一直改……

最后灵光一闪（脑袋坏了），改成了这样：

b.inbox['喵子弹'] =+ selection

改好了）））））

后来又写了玩家拿出子弹，这下子各种方法都没办法了:

...+=.../...=...+.../...=+.../...+.../...=...+=...

后面两个瞎想的。。。。。。。

所以你们怎么么看（）

全部代码：

for(const b of world.querySelectorAll('.箱子')){
        b.inbox = {'喵子弹':0,'喵子弹':0,'医疗包':0,'手雷':0}
        b.enableInteract = true
        b.interactRadius = 2
        b.interactHint = '箱子'
        b.onInteract(async({entity}) => {
