ResolveTexture2D - XNA 4 中的噩梦 [英] ResolveTexture2D - The nightmare in XNA 4

问题描述

我有以下声明:

ResolveTexture2D rightTex;

我在 Draw 方法中使用它，如下所示:

And I use it in the Draw method like so:

GraphicsDevice.ResolveBackBuffer(rightTex);

现在，我然后使用 SpriteBatch 绘制它:

Now, I then draw it out using the SpriteBatch:

spriteBatch.Draw(rightTex, new Rectangle(0, 0, 800, 600), Color.Cyan);

这在 XNA 3.1 中效果很好.但是，现在我正在转换为 XNA 4，ResolveTexture2D 和 ResolveBackBuffer 方法已被删除.我将如何重新编码以便在 XNA 4.0 中工作?

This works fantastic in XNA 3.1. But, now I'm converting to XNA 4, ResolveTexture2D and the ResolveBackBuffer method have been removed. How would I re-code this in order to work in XNA 4.0?

编辑

所以，这里还有一些代码可能会有所帮助.在这里，我初始化了 RenderTargets:

So, here is some more code to maybe help. Here I initialise the RenderTargets:

PresentationParameters pp = GraphicsDevice.PresentationParameters;
leftTex = new RenderTarget2D(GraphicsDevice, pp.BackBufferWidth, pp.BackBufferHeight, true, pp.BackBufferFormat, pp.DepthStencilFormat);
rightTex = new RenderTarget2D(GraphicsDevice, pp.BackBufferWidth, pp.BackBufferHeight, true, pp.BackBufferFormat, pp.DepthStencilFormat);

然后，在我的 Draw 方法中:

Then, in my Draw method I do:

GraphicsDevice.Clear(Color.Gray);
rightCam.render(model, Matrix.CreateScale(0.1f), modelAbsTrans);
GraphicsDevice.SetRenderTarget(rightTex);
GraphicsDevice.SetRenderTarget(null);

GraphicsDevice.Clear(Color.Gray);
leftCam.render(model, Matrix.CreateScale(0.1f), modelAbsTrans);
GraphicsDevice.SetRenderTarget(leftTex);
GraphicsDevice.SetRenderTarget(null);

GraphicsDevice.Clear(Color.Black);

//start the SpriteBatch with Additive Blend Mode
spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Additive);
    spriteBatch.Draw(rightTex, new Rectangle(0, 0, 800, 600), Color.Cyan);
    spriteBatch.Draw(leftTex, new Rectangle(0, 0, 800, 600), Color.Red);
spriteBatch.End();

推荐答案

啊，给你:在 GraphicsDevice.Clear() 调用之前移动 GraphicsDevice.SetRenderTarget()

ahhh, here you go: Move the GraphicsDevice.SetRenderTarget() before the GraphicsDevice.Clear() call
