Float:32位单精度浮点型,其中1符号位、8指数位、23数值位,UE4中默认保留小数点后6位。UE4中只有Float类型没有Double类型。 2. 字符串 String: :蓝图中String类型就是蓝图C++中的FString类型,普通字符串,可以对其中的字符进行增删查改。 Name :是一种固定字符串类型,变量初始化以后不能在对其中的内容进行修改,...

FString 是一种动态字符串,实际上就类似于我们所熟悉的std::string类型,是我们平时编写UE4 C++代码时最常需要用到的字符串类型。 由于动态的特性,FString拥有以下特点: 支持很多字符串操作(例如转换int32/float,字符串拼接,查找子字符串,逆置) 开销比静态(不可变)字符串类(FName、FText)要更大 ...
