More than one effect?

[Yikes]

Hey, is there any way to have more than one effect on something like a layer? I can't seem to figure out how to do that :P

[King_Cool]

There are effect for entire Layers?

No you can't have more than one pixel shader effect per layer. However what you can do is easily combine pixel shader code so you'll have multiple effects in 1 pixel shader. I've done this personally myself and it works like a charm. Make sure you update the .xml file so it displays the correct information in MMF2 aswell. If you need more help i'll post an example of 2 shaders combined



As you can see I combined the Flip + Tint shaders.

[Yikes]

Ah, thanks I will see if I can do that, but my programming skills aren't the best. An example would be appreciated. I am trying to combine the monochrome and directional blur effects right now. The problem is that I need to "fuse together" the output colour codes, and I really don't know how to do that xD

Edit: Is there btw a way to make everything black and white, except the reds? So everything is black and white but blood and other red things are normal..

Check my shaders page, I believe someone made one like that...

At the '11 convention Clickteam didn't seem to think there'd be a problem with implementing stacking pixel shaders in MMF3. I hope that's still the case as it's a staple of many good game dev tools.

Copy & Paste this in a new .fx text file

// Pixel shader input structure
struct PS_INPUT
{
    float4 Position   : POSITION;
    float2 Texture    : TEXCOORD0;
};

// Pixel shader output structure
struct PS_OUTPUT
{
    float4 Color   : COLOR0;
};

// Global variables
sampler2D Tex0;
float fCoeff;

PS_OUTPUT ps_main( in PS_INPUT In )
{
    // Output pixel

    PS_OUTPUT TexL;
    PS_OUTPUT TexBL;
    PS_OUTPUT TexB;
    PS_OUTPUT TexBR;
    PS_OUTPUT TexR;
    PS_OUTPUT TexTR;

//CS_Blur

TexT.Color = tex2D(Tex0, float2(In.Texture.x,In.Texture.y-

fCoeff));
    TexTL.Color = tex2D(Tex0, float2(In.Texture.x-

fCoeff,In.Texture.y-fCoeff));
    TexL.Color = tex2D(Tex0, float2(In.Texture.x-

fCoeff,In.Texture.y));
    TexBL.Color = tex2D(Tex0, float2(In.Texture.x-

fCoeff,In.Texture.y+fCoeff));
    TexB.Color = tex2D(Tex0, float2

(In.Texture.x,In.Texture.y+fCoeff));
    TexBR.Color = tex2D(Tex0, float2(In.Texture.x

+fCoeff,In.Texture.y+fCoeff));
    TexR.Color = tex2D(Tex0, float2(In.Texture.x

+fCoeff,In.Texture.y));
    TexTR.Color = tex2D(Tex0, float2(In.Texture.x

+fCoeff,In.Texture.y-fCoeff));
    Out.Color = tex2D(Tex0, float2

(In.Texture.x,In.Texture.y));
    
    Out.Color = (Out.Color+TexT.Color+TexTL.Color+TexL.Color

+TexBL.Color+TexB.Color+TexBR.Color+TexR.Color+TexTR.Color)/9;

//monochrome

    
    float4 f4 = (Out.Color+TexT.Color+TexTL.Color+TexL.Color

+TexBL.Color+TexB.Color+TexBR.Color+TexR.Color+TexTR.Color)/9 * 

float4(0.299f, 0.587f, 0.114f, 1.0f);
    float f = f4.r + f4.g + f4.b;
    Out.Color.rgb = f;

    return Out;
}

// Effect technique
technique tech_main
{
    pass P0
    {
        // shaders
        VertexShader = NULL;
        PixelShader  = compile ps_2_0 ps_main();
    }  
}

--------------------------------------------------------
The only thing I did was made sure the Out.Color = (Out.Color+TexT.Color+TexTL.Color+TexL.Color+TexBL .Color+TexB.Color+TexBR.Color+TexR.Color+TexTR.Col or)/9) * the float4 of the monochrome value. The only parameter you need is the fCoeff which is for adjusting the blur.
--------------------------------------------------------
For the .xml document you can make it however it want, but here is how I structured it:

<effect>
<name>MonoChrome + Blur Shader Example</name>
<description>Monochrome does not have any parameters. Blur provides Blurring through the coefficient parameter.</description>

<parameter>
        <name>Coeff</name>
        <code>fCoeff</code>
        <description>Blur offset coefficient</description>
        <type>float</type>
        <property>edit</property>
        <value>0.01</value>
        <min>0.0</min>
        <max>0.5</max>
</parameter>
</effect>

Edit: I just realized you wanted directional blur instead of just a regular blur..err copy this instead to the .fx file:

// Pixel shader input structure
struct PS_INPUT
{
    float4 Position   : POSITION;
    float2 Texture    : TEXCOORD0;
};

// Pixel shader output structure
struct PS_OUTPUT
{
    float4 Color   : COLOR0;
};

// Global variables
sampler2D Tex0;
float fCoeff;
float fAngle;


PS_OUTPUT ps_main( in PS_INPUT In )
{
    // Output pixel
    PS_OUTPUT Out;
  PS_OUTPUT OutA;
  PS_OUTPUT OutB;
    fAngle = fAngle*0.0174532925f;
    OutA.Color = tex2D(Tex0, float2(In.Texture.x+cos(fAngle)

*fCoeff,In.Texture.y+sin(fAngle)*fCoeff));
    OutB.Color = tex2D(Tex0, float2(In.Texture.x-cos(fAngle)

*fCoeff,In.Texture.y-sin(fAngle)*fCoeff));
    Out.Color = tex2D(Tex0, In.Texture.xy);
    Out.Color = (Out.Color+OutA.Color+OutB.Color)/3;

//monochrome

    
    float4 f4 = (Out.Color+OutA.Color+OutB.Color)/3 * float4

(0.299f, 0.587f, 0.114f, 1.0f);
    float f = f4.r + f4.g + f4.b;
    Out.Color.rgb = f;

    return Out;
}

// Effect technique
technique tech_main
{
    pass P0
    {
        // shaders
        VertexShader = NULL;
        PixelShader  = compile ps_2_0 ps_main();
    }  
}

--------------------------------------------------------
and the .xml file :

<effect>
<name>MonoChrome + Directional Blur Shader Example</name>
<description>Monochrome does not have any parameters. DirBlur provides Blurring through direction and coefficient.</description>

<parameter>
    <name>Coefficient</name>

Thanks! I really appreciate you taking the time to post the complete solution I will make sure I read the code properly so I understand it till next time

And thanks Phi, I found a shader on the suggested webpage with a monochrome effect and excluded colours LOVE IT!

At the '11 convention Clickteam didn't seem to think there'd be a problem with implementing stacking pixel shaders in MMF3. I hope that's still the case as it's a staple of many good game dev tools.

Nice, I hope they implement that Would make things a lot easier!

Anaconda runtime have that option and extension called anaconda Shaders...
