pixel shader wont load

[Eagle_Eye]

for some reason, the pixel shader wont load correctly, i should be seeing red as the color of the mesh i added the material to but i don't see it, the vertex shader loaded good as it didn't tell me that it didn't load the vertex shader, i don't know what to do.....
here is my shader code:

Code: Select all

float4x4 matViewProjection : ViewProjection;
float4 Color;
struct VS_OUT
{
    float4 Postion : POSITION;
    
};

VS_OUT vsmain(in float4 Pos : POSITION)
{
	VS_OUT Out;
	Out.Postion = mul(Position,matViewProjection);

	float4 Color = float4(1,0,0,0);
}

float4 psmain() : COLOR
{ 
   Color = float4(1,0,0,0);
   return Color;
}

I hope you can help me......

What do you see?

this is what i see, the house should be red since i loaded the pixel shader along with the vertex shader so i don't know what to do, i mean it loaded the vertex shader, yet it can't load the pixel shader even though it's the same file?

Looks like the material isn't being set. Start at the shader example and see if you can get it working there, or post the code where you set the material on the node.

Code: Select all

	video::IGPUProgrammingServices* gpu = g_pIrr->getVideoDriver()->getGPUProgrammingServices();

	s32 _Red= 0;

	if(gpu)
	{
		MYSHADERCONSTANCE* mc = new MYSHADERCONSTANCE();

		_Red = gpu->addHighLevelShaderMaterialFromFiles(
			"Red_Shader.hlsl", "vsmain", video::EVST_VS_1_1,
			"Red_Shader.hlsl,","psmain", video::EPST_PS_1_1,
			mc, video::E_MATERIAL_TYPE::EMT_TRANSPARENT_ADD_COLOR);
		
		if(_Red)
		{
			MessageBoxA(NULL,"Shader Loaded","Object",MB_OK);
		}
	}
	
	Level_Node->setMaterialType((E_MATERIAL_TYPE)_Red);

here is the code i used to load the material shaders and set it to the level_node, other then that i don't know what other code to give.

also, does the console give errors?

[geckoman]

I see an error ->

Code: Select all

struct VS_OUT
{
    float4 Postion : POSITION;
   
};  

Should be Position instead of Postion. Maybe it helps

[Eagle_Eye]

this is what the console says

Code: Select all

Could not open pixel shader program file: Red_Shader.hlsl,

doesn't say why it can't open it though

[Eagle_Eye]

I tried the shader that comes with Irrlicht and it can't open it either so i don't know what i'm doing wrong......I could always use .FX files but those don't go well with Irrlicht Matrices..

You see, this helps:

"Red_Shader.hlsl,","psmain", video::EPST_PS_1_1,

Maybe you spot the , inside your quotes, this is a simply typo

[Eagle_Eye]

Code: Select all

HLSL vertex shader compilation failed:
(12): error X3018: invalid subscript 'Postion'

and i fixed it, what could it be?

[Eagle_Eye]

Never mind, i got it to work, finally......from now on i'll look at the console to see any errors. thanks for all your help

New problem, i can't seem to set the texture on a mesh using shaders, it gives me

Code: Select all

rror setting float array for HLSL variable

here is my shader code for this effect

Code: Select all

float4x4 matViewProjection : ViewProjection;

struct VS_INPUT 
{
   float4 Position : POSITION0;
   float2 TEX      : TEXCOORD0;
};

struct VS_OUTPUT 
{
   float4 Position : POSITION0;
   float2 TEX      : TEXCOORD0; 
};

VS_OUTPUT vs_main( VS_INPUT Input )
{
   VS_OUTPUT Output;

   Output.Position = mul( Input.Position, matViewProjection );
   
   Output.TEX = Input.TEX;
   
   return( Output );
   
}




texture Fieldstone_Tex
<
   string ResourceName = "..\\..\\..\\..\\..\\..\\..\\Program Files (x86)\\AMD\\RenderMonkey 1.82\\Examples\\Media\\Textures\\Fieldstone.tga";
>;
sampler2D Texture0 = sampler_state
{
   Texture = (Fieldstone_Tex);
};
sampler2D Texture1;
struct PS_OUT
{
   float2 Tex : TEXCOORD0;
   
};

float4 ps_main(in PS_OUT IN) : COLOR0
{   

   return( tex2D(Texture0,IN.Tex)  );
   
}

I'm setting the texture this way:

Code: Select all

ITexture* Field;
		services->setPixelShaderConstant("Texture0",(float*)&Field,1);

any ideas?
