刷新WPF游戏窗口最聪明的方法是什么？ [英] What's the smartest way to refresh the window for a WPF game?

问题描述

我正在为WPF创建一个游戏引擎。我正试图从DispatcherTimer转移到StopWatch，以获得更恒定的游戏速度（如果游戏中的对象太多，DispatcherTimer将跳过转动）。



我可以使用StopWatch编写正确更新游戏的代码（也就是说，我的游戏对象的速度和位置是正确计算的），但是当我省略DispatcherTimer时，GUI将永远不会重绘。



我知道有几种方法可以强制重绘窗口，但是什么是WPF中2D游戏的最佳选择？我只是在寻找一些简单而有效的方法而不会有太多麻烦。



这是我目前在屏幕上放置对象的代码，每秒多次：< （$ i $ 0; i< Bodies.NumberOfBodies（）;
{
Body body = Bodies}

Hi,

I am creating a game engine for WPF. I am trying to move away from DispatcherTimer to StopWatch, to get a more constant speed of the game (as DispatcherTimer skips turns if there are too many objects in the game).

I can write the code for updating the game correctly using a StopWatch (that is, my game objects' speeds and positions are calculated correctly), but when I omit the DispatcherTimer the GUI will never redraw.

I know there are several ways to force a redraw of the window, but what would be my best option for a 2D game in WPF? I'm just looking for something simple that works rather efficiently without a lot of hassle.

This is my current code for placing objects onscreen, many times per second:

for (int i = 0; i < Bodies.NumberOfBodies(); 
{
    Body body = Bodies.Bodylist[i];
    var shape = body.GetShape();
    game.Children.Add(shape); //each movable body's shape is added again. 

    Canvas.SetLeft(shape, body.PosX - offsetX);
    Canvas.SetTop(shape, body.PosY - offsetY);
}

谢谢！
