以PS设置启动参数为例:

要在游戏中获取启动参数值,须要晓得启动参数,保留的地位:
须要理解【Engine\Source\Runtime\Core\Public\Misc\CommandLine.h】

/**      * Returns an edited version of the executable's command line     *  with the game name and certain other parameters removed     * 获取启动参数字符串.      */    static const TCHAR* Get();    /**     * Parses a string into tokens, separating switches (beginning with -) from     * other parameters     * 解析命令字符串     *     * @param    CmdLine        the string to parse     * @param    Tokens        [out] filled with all parameters found in the string     * @param    Switches    [out] filled with all switches found in the string     */    static void Parse(const TCHAR* CmdLine, TArray<FString>& Tokens, TArray<FString>& Switches);

应用形式

    TArray<FString> Tokens;    TArray<FString> Switches;    FCommandLine::Parse(FCommandLine::Get(), Tokens, Switches);

只须要解析Switches的字符串就能够获取,key与Value;在这里key:Dev,Value:PS4测试服;具体如何应用,由游戏决定
