I have some problem with my shader. I have function which sets variables in my pixel shader. It works fine for all my shaders, but not for this
float4x4 xView;
float4x4 xProjection;
float4x4 xWorld;
float3 xCamPos;
float3 xAllowedRotDir;
Texture xBillboardTexture : TEXTURE0;
sampler textureSamplerTree = sampler_state
{
texture = <xBillboardTexture>;
magfilter = LINEAR;
minfilter = LINEAR;
mipfilter = LINEAR;
AddressU = CLAMP;
AddressV = CLAMP;
};
struct BBVertexToPixel
{
float4 Position : POSITION;
float2 TexCoord : TEXCOORD0;
};
struct BBPixelToFrame
{
float4 Color : COLOR0;
};
BBPixelToFrame BillboardPS(BBVertexToPixel PSIn)
{
BBPixelToFrame Output = (BBPixelToFrame)0;
Output.Color = tex2D(textureSamplerTree, PSIn.TexCoord);
return Output;
}
/*Vertex shader not important*/
BBVertexToPixel CylBillboardVS(float3 inPos: POSITION0, float2 inTexCoord: TEXCOORD0)
{
BBVertexToPixel Output = (BBVertexToPixel)0;
float4 inPosTmp = float4(inPos, 1);
float4 center = mul(inPosTmp, xWorld);
float3 eyeVector = center.xyz - xCamPos;
float3 upVector = xAllowedRotDir;
upVector = normalize(upVector);
float3 sideVector = cross(eyeVector,upVector);
sideVector = normalize(sideVector);
float3 finalPosition = center.xyz;
finalPosition += (inTexCoord.x-0.5f)*sideVector * 5.0f;
finalPosition += (1.5f-inTexCoord.y*1.5f)*upVector * 5.0f;
float4 finalPosition4 = float4(finalPosition, 1);
float4x4 preViewProjection = mul (xView, xProjection);
Output.Position = mul(finalPosition4, preViewProjection);
Output.TexCoord = inTexCoord;
return Output;
}Now my setter function
HRESULT Shader::SetTexture(IDirect3DTexture9 * baseTexture, char * var_name)
{
D3DXHANDLE handle;
handle = pdxVertexConstants->GetConstantByName(NULL, var_name);
if (localDevice && pdxPixelConstants && (handle = pdxPixelConstants->GetConstantByName(NULL, var_name)))
{
DWORD shaderSamplerIndex = pdxPixelConstants->GetSamplerIndex(handle);
localDevice->SetTexture(shaderSamplerIndex, baseTexture);
return S_OK;
}
return E_FAIL;
}and always GetConstantByName(NULL, "xBillboardTexture") returns me NULL.
I can't understand where is problem.
