本文详细介绍了如何在Unreal Engine 4（UE4）中执行操作，以启动和控制外部的.exe程序，这对于游戏开发中的交互性和系统集成至关重要。

public:
 
 
    UFUNCTION(BlueprintCallable, Category = "Utilities")
        static bool OpenExe(FString ExeURL);
    UFUNCTION(BlueprintCallable, Category = "Utilities")
        static bool IsExeRunning();
    UFUNCTION(BlueprintCallable, Category = "Utilities")
        static void CloseExe();
 
 
 
FProcHandle ExeHandle;
 
bool UTestFunctionLibrary::OpenExe(FString ExeURL)
{
    if (FPlatformProcess::CanLaunchURL(*ExeURL))
    {
        UE_LOG(LogBlueprintFunc, Warning, TEXT("OpenExe CanLaunchURL false"));
        return false;
    }
     ExeHandle = FPlatformProcess::CreateProc(*ExeURL, nullptr, true, false, false, nullptr, 0, nullptr, nullptr);
    UE_LOG(LogBlueprintFunc, Warning, TEXT("OpenExe URL:::%s"), *ExeURL);
 
    //FPlatformProcess::CloseProc(currHandle);
    bool ret = FPlatformProcess::IsProcRunning(ExeHandle);
    return ret;
}
 
bool UTestFunctionLibrary::IsExeRunning() 
{
    bool ret = FPlatformProcess::IsProcRunning(ExeHandle);
    return ret;
}
 
void  UTestFunctionLibrary::CloseExe()
{
    FPlatformProcess::CloseProc(ExeHandle);
}
