简单的动画中的WinForms [英] Simple animation in WinForms

问题描述

假设你想在一个WinForm动画的一些对象。您设置一个计时器，更新状态或模型，并覆盖窗体的Paint事件。但是，从那里，什么是不断重新绘制表格动画的最佳方式是什么？

Imagine you want to animate some object on a WinForm. You setup a timer to update the state or model, and override the paint event of the Form. But from there, what's the best way to continually repaint the Form for the animation?

• 只要你完成绘制？
无效的形式
• 在安装第二个定时器和形式固定时间间隔无效？
• 或许有一个共同的模式这个东西？
• 是否有任何有用的.NET类来帮帮忙？

每当我需要做的这一点，我发现了一个新的方法，新的缺陷。什么是从SO社区的经验和建议？

Each time I need to do this I discover a new method with a new drawback. What are the experiences and recommendations from the SO community?

推荐答案

在某些情况下，它的速度更快，更方便地不画使用油漆事件，但得到的图形从控制/表格和绘画的对象，该对象。这可能会给一些麻烦与不透明/抗锯齿/文本等，但可能是值得不必重绘整个shabang方面的麻烦。线沿线的东西：

In some situations, it's faster and more convenient to not draw using the paint event, but getting the Graphics object from the control/form and painting "on" that. This may give some troubles with opacity/anti aliasing/text etc, but could be worth the trouble in terms of not having to repaint the whole shabang. Something along the lines of:

private void AnimationTimer_Tick(object sender, EventArgs args)
{
    // First paint background, like Clear(Control.Background), or by
    // painting an image you have previously buffered that was the background.
    animationControl.CreateGraphics().DrawImage(0, 0, animationImages[animationTick++])); 
}

我用这个在一些控制自己，并有缓冲的图像，以清的背景，当被删除感兴趣的移动对象或需要。

I use this in some Controls myself, and have buffered images to "clear" the background with, when the object of interest moves or need to be removed.
