Question

我在XNA上遇到基元问题。正如您在链接http://imgur.com/12UTd2s中看到的那样，一些纹理墙是透明的，有些不是。有人可以解释为什么会发生这种情况并帮助我找到解决方案吗？

这是透视墙宣言：

testWall.Add(new VertexPositionNormalTexture(new Vector3(x2, 0, z2), new Vector3(1, 0, 0), new Vector2(0,0)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x2, 0, z2 - 50), new Vector3(1, 0, 0), new Vector2(1,0)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x2, 20, z2), new Vector3(1, 0, 0), new Vector2(0,1)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x2, 20, z2), new Vector3(1, 0, 0), new Vector2(0,1)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x2, 20, z2 - 50), new Vector3(1, 0, 0), new Vector2(1,1)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x2, 0, z2 - 50), new Vector3(1, 0, 0), new Vector2(1,0)));

这里是我无法透露的隔离墙宣言：

testWall.Add(new VertexPositionNormalTexture(new Vector3(x1, 0, z1 - 50), new Vector3(-1, 0, 0), new Vector2(0,1)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x1, 0, z1), new Vector3(-1, 0, 0), new Vector2(0,0)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x1, 20, z1 - 50), new Vector3(-1, 0, 0), new Vector2(1,1)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x1, 20, z1 - 50), new Vector3(-1, 0, 0), new Vector2(1,1)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x1, 20, z1), new Vector3(-1, 0, 0), new Vector2(1,0)));
                    testWall.Add(new VertexPositionNormalTexture(new Vector3(x1, 0, z1), new Vector3(-1, 0, 0), new Vector2(0,0)));

剔除设置为无，x2，x1，z1，z2为顶点位置。有什么想法吗？

谢谢

原因不是因为它们是透明的，而是因为您没有启用深度缓冲，所以墙壁将按照它们被绘制的顺序（从下到上）显示。

在渲染之前，您想要设置渲染状态：

Renderer.GraphicsDevice.DepthStencilState = DepthStencilState.Default;

XNA纹理基元是透视的
