Pixel Shader 3.0：TEXCOORD始终为0,0 [英] Pixel Shader 3.0: TEXCOORD always be 0,0

问题描述

我正在使用DirectX 9.0c并使用基于Pixel Shader 3.0的ID3DXSprite :: Draw开发2D游戏，但我不知道为什么"Coord"总是（0.0f，0.0f）

sampler2D s2D;

float4 PShader（float2 Coord：TEXCOORD，float4颜色：COLOR）：COLOR

{

   返回tex2D（s2D，Coord）*颜色;

}

但它适用于Pixel Shader 2.0

解决方案

Hi holihand，

这是一个名为Visual Studio Graphics Debugger的调试工具。 Visual Studio Graphics Debugger极大地提高了可用性，支持Windows 8和Direct3D 11.1，并集成了传统的Visual Studio功能，如调用堆栈和调试

以下是一些关于在Direct3D 9中编写着色器的文档。

I'm using DirectX 9.0c and developing a 2D game using ID3DXSprite::Draw based on Pixel Shader 3.0, but I don't know why the "Coord" always be (0.0f, 0.0f)

sampler2D s2D;

float4 PShader(float2 Coord : TEXCOORD, float4 Color : COLOR) : COLOR
{

    return tex2D(s2D, Coord) * Color;

}

But it work on Pixel Shader 2.0

Hi holihand,

thanks for posting here.

Here is a debug tool called Visual Studio Graphics Debugger. Visual Studio Graphics Debugger has greatly improved usability, support for Windows 8 and Direct3D 11.1, and integration with traditional Visual Studio features such as call stacks and debugging windows for HLSL debugging.

For more info about this new feature, see Debugging DirectX Graphics.

And here are some documents about Writing Shaders in Direct3D 9.
