D3DXCreateEffectFromFile Problems [solved]

Recommended Posts

Hey gamedevelopers. I have a little problem. I want to get started with shaders/effects but i still do not have a working example which allows me to expiriment with effect files. For some reason, the BasicHLSL sample from the SDK doesn't work. So i tried to turn the Meshes tutorial (with the nice tiger) into a shader testing app. But the first thing that didn't work was: D3DXCreateEffectFromFile. It returns E_FAIL wich is a very strange return value for a DX routine. I don't see anything suspicious in the debug-runtime logfile. maybe i can use PIX to determine what the hell is going on, but i don't know how to debug the D3D initialization by using PIX. The PIX tut's only explain stuff like taking screenshots and recording D3D call sequences in a specific frame. I used different effect files. e.g this one: ------------------------------------------------------------------ //===================================== // My first Effect file //===================================== //Variabeles float4x4 g_mWorldViewProjection; texture g_MeshTexture; //structures struct VS_OUTPUT { float4 Position : POSITION; float2 TextureCoords: TEXCOORD1; }; struct PS_OUTPUT { float4 Color : COLOR0; }; //-------------------------------------------------------------------------------------- // Texture samplers //-------------------------------------------------------------------------------------- sampler MeshTextureSampler = sampler_state { Texture = <g_MeshTexture>; MipFilter = LINEAR; MinFilter = LINEAR; MagFilter = LINEAR; }; VS_OUTPUT VS_function( float4 vPos : POSITION, float2 vTexCoord0 : TEXCOORD0 ) { VS_OUTPUT Output; Output.Position = mul( vPos, g_mWorldViewProjection ); Output.TextureCoords = vTexCoord0; return Output; } PS_OUTPUT PS_function(VS_OUTPUT input) { PS_OUTPUT output; output.Color = tex2D(MeshTextureSampler, input.TextureCoords); return output; } //my first technique Technique MyTechnique { Pass FirstPass { VertexShader = compile vs_1_1 VS_function(); PixelShader = compile ps_1_1 PS_function(); } } ----------------------------------------------------------------------- This effect file should compile in FX composer but somehow D3DXCreateEffectFromFile keeps failing. Can someone help me with this. plz.? Thanx in advance [Edited by - chronozphere on August 5, 2007 3:56:36 PM]

If you enable the debug runtimes (Start -> Programs -> DirectX SDK -> Utilities -> DX Control Panel) you should start getting debug output from your application indicating why the function failed.

If you're using VS, this will show in the "Output" window while the program runs. If you're not using VS, you can use DebugView to capture this debug output.

Once you do that, you'll know exactly what D3DX doesn't like about your .fx file.

Another alternative is to compile your .fx file from the command line, using fxc.exe file.fx /tfx_2_0 . This will provide output when an error is encountered.

Hope this helps.

It could be any number of things, but I'm guessing the EXE is run from a "output/debug" directory or something similar, and it looking for data files from there. It's simply not finding your file. You just need to set the working folder in your project settings and you should be set.

The effect file i pass to the function does exist.

I used this code (pascal):


str := ExtractFilePath(ParamStr(0))+'effect1.fx';
//check if file exists
if FileExists(str) then
begin
//load the effect
HR := D3DXCreateEffectFromFile(g_pd3ddevice ,pChar(str),nil,nil,0,nil,g_effect,Errors);
if Failed(HR) then
begin
Showmessage('Error occured: '+DXGetErrorString9A(HR)+' while loading: '+str);
Exit;
end;
end;


I check if the file exists so that cant be the problem. I always get the message:

Error Occured: E_FAIL while loading: E:\ **filepath** \effect1.fx

I downloaded debugview but it didn't return ANY debug messages, no matter what kind of capture options i selected.

However i did forget to set a specific compiler directive in D3DX9.pas (which enables D3DX debugging). It delivered the following log-file.

De SXS messages are added since i enabled D3DX debugging. I do not understand what those messages mean. Can someone take a look at this?

I have the feeling that i'm missing something, because i expect an error when a DX function doesn't work.

That feeling was correct because i WAS missing something.

The problem was that i used the wrong pascal headers. Another pascal-coder pointed out to me that i should enable D3DX Debugging by setting a compiler directive in the D3DX9 header.
But the headers i was using didn't support D3DX Debugging (it was mentioned in the header itself). So i used the JEDI headers which did support it.

When i solved that it was simply a matter of eliminating 2 errors in the effect file. After that D3DXCreateEffectFromFile was executed succesfully. :)

Thanx anyway for your help ;)
