我有一个脚本给我错误：
Assets / Soccer Project / Scripts / Player_Script.cs（493,11）：错误CS0136：在此范围内无法声明名为'distanceBall'的局部变量，因为它会给`distanceBall'赋予不同的含义，这已经是用于“子”范围以表示其他内容
我在网上找不到任何好的答案，也不知道如何修复它，这是脚本：

答案 0 :(得分：1)
你的剧本太大了;你需要把它拆分成更小的，以便你更容易使用。
错误告诉您，您正在尝试使用已在该范围内使用的名称声明变量。我没有通过你的长代码来查找你正在做的事情，但它有点像这样：
if (...)
{
float distanceBall;
}
float distanceBall;
您需要为其中一个提供不同的名称或事先声明：
float distanceBall;
if (...)
{
...
}
...
