UE4 http请求循环

Question

我正在循环一个http请求，并调用一个url来请求json指令。我必须循环，以便知道游戏应该做的下一件事。如果我把游戏打包，它会运行得很流畅。但在开发中并按下play时，游戏仍在继续，但除非我单击游戏窗口，否则视口上的输出大约是10fps。如果键盘或鼠标的焦点在另一个窗口而不是编辑器上，则视口面板似乎是故意这样做的。

Request = FHttpModule::Get().CreateRequest(); 

Request->OnProcessRequestComplete().BindUObject(this, &ABoxGridActor::OnResponseReceived);
//   //This is the url on which to process the request
Request->SetURL("http://localhost:8092"); 
Request->SetVerb("GET");
Request->SetHeader(TEXT("User-Agent"), "X-UnrealEngine-Agent");
Request->SetHeader("Content-Type", TEXT("application/json"));
//Request->ProcessRequest();

////not timer loop, one time only
GetWorldTimerManager().SetTimer(tmr, this, &ABoxGridActor::RepeatingFunction, 0.2f, true);

void ABoxGridActor::RepeatingFunction()
{
    if (!boolHasPassed)
    {
        boolHasPassed = true;
        Request->ProcessRequest();
        return;
    }

}

void ABoxGridActor::OnResponseReceived(FHttpRequestPtr RequestP, FHttpResponsePtr Response, bool bWasSuccessful)
{
    boolHasPassed = false;

    //codes
}

Answer 1

当游戏未处于焦点状态时，您可以通过禁用该选项来禁用使用较少资源的编辑器：

Edit -> Editor Preferences -> General -> Performance -> Use Less CPU when in Background
