[英]How do you convert an FString of delimited floats to a TArray<uint16> using Unreal C++
Given an FString of "123.2222,446.4444,55234.2342" how do you convert this to a TArray of type uint16?给定“123.2222,446.4444,55234.2342”的 FString,如何将其转换为 uint16 类型的 TArray?
Current attempt is to parse the string into an array using当前的尝试是使用将字符串解析为数组
TArray<FString> Parsed;
HeightMapData.ParseIntoArray(Parsed, TEXT(","), false);
This seems to work well.这似乎运作良好。 Next is the problem of how do I convert this to uint16.接下来是如何将其转换为 uint16 的问题。
I am trying我在尝试
const TArray<uint16*>& parsedArray = reinterpret_cast<const TArray<uint16*>&>(Parsed);
But it is not working.但它不起作用。 Error: Parent address is invalid for parsedArray错误:parsedArray 的父地址无效
You can't reinterpret_cast
and pretend your array of strings is an array of integers.您不能reinterpret_cast
并假装您的字符串数组是整数数组。 You need to convert each string to an integer in a new array:您需要将每个字符串转换为新数组中的 integer:
TArray<uint16> intArray;
for (const auto& str : Parsed)
intArray.Add(FCString::Atoi(str));
