根据代码,第四个循环是向panel中添加18个箭头,第五个循环是向panel中添加jiaNumber个加号,第六个循环是向panel中添加dunNumber个盾牌。如果第二次激活后第四五个循环没有作用,那么可能是因为panel中已经存在了这些对象,导致添加不上去。你可以在循环前先检查一下panel中是否已经存在这些对象,如果存在就跳过添加的操作。另外,如果你想要在第二次激活后重新添加这些对象,可以在OnDisable()方法中将panel和showPanel中的所有子对象销毁,这样在下一次激活时就能重新添加了。

这段代码中有一个变量`flag`,在第一个循环之前没有初始化,因此第二次激活时`flag`的值可能是不正确的,导致后面的循环没有执行。建议将`flag`的初始值在函数开始时设为0,例如在函数开头处添加`flag = 0;`。
此外,如果第二次激活后仍然没有执行第四五个循环,可以在代码中添加一些`Debug.Log`语句来输出变量的值,以便进行排查错误原因。
for (int i = 0; i < cityTransforms.childCount; i++) { gongJiChengShiBeans[i].city = cityTransforms.GetChild(i).gameObject.name; gongJiChengShiBeans[i].count = 1; gongJiChengShiBeans[i].type = (i == 0) ? 1 : (gongJiChengShiBeans[i - 1].type % 5) + 1; } 优化代码
为了优化这段代码,我注意到可以减少对 `cityTransforms.GetChild(i).gameObject` 的多次访问。此外,可以将 `(i == 0) ? 1 : (gongJiChengShiBeans[i - 1].type % 5) + 1` 的计算提取到循环外,避免重复计算。下面是优化后的代码:
```csharp
int previousType = 1;
for (int i = 0; i < cityTransforms.childCount; i++)
{
Transform childTransform = cityTransforms.GetChild(i);
GongJiChengShiBean gongJiChengShiBean = gongJiChengShiBeans[i];
gongJiChengShiBean.city = childTransform.gameObject.name;
gongJiChengShiBean.count = 1;
gongJiChengShiBean.type = (previousType % 5) + 1;
previousType = gongJiChengShiBean.type;
}
```
这样,代码中的 `cityTransforms.GetChild(i).gameObject` 只被访问一次,并且计算 `(previousType % 5) + 1` 只在循环外进行一次。这样可以提高代码的效率。
