问题描述
我知道我必须在draw（）中绘制所有内容，并且它不断循环。
I understand that I have to draw everything in draw(), and it's looping continuously.
但是我不想一次又一次地绘制纹理，例如，我想创建一个纹理，绘制一些要纹理的东西（而不是spritebatch）。比我只会在draw（）中绘制该纹理。
But I don't want to draw texture again and again, for example I want to create a texture, draw something to texture (not spritebatch). than I will only draw that texture in draw().
有可能吗？
我可以使用什么？
Is it possible?What can I use?
推荐答案
不重新绘制它是一种性能优化。仅在确实需要时才应该这样做。
Not drawing it again is a performance optimisation. You should only do that if you really need to.
如果确实需要这样做，则创建一个渲染目标，将场景绘制为渲染目标，然后将渲染目标每帧绘制到屏幕上（使用 SpriteBatch 可以很容易地）而不是场景。
If you do need to do this, create a render target, draw your scene to the render target, and then draw your render target to the screen each frame (using SpriteBatch makes this easy) instead of your scene.
看看。
