Hi tomedison
I see in your profile that you recently joined Mpnogame
So i would suggest first to read first some tutos:

Where have found Activity1 class?

New Post: Another shader issue...

cdxrd — Sun, 19 May 2013 20:29:34 GMT

Ok, I dont get it.. Been staring at this for 2 days and can not figure out why I cant get this to work with monogame.. if I build this with Vis studio 2010, it works perfectly.. I can get it to display and work perfectly... I can even get it to build properly using the monogame content project for win8... but then I cant get it to display... I get a blank screen.. same code being used in both projects..

sampler2D samplerState;  

//Width to sample from
float mag;

//Alpha value
float alpha;

float   dessatAmount; 

const float2 offsets[12] = {
   -0.326212, -0.405805,
   -0.840144, -0.073580,
   -0.695914,  0.457137,
   -0.203345,  0.620716,
    0.962340, -0.194983,
    0.473434, -0.480026,
    0.519456,  0.767022,
    0.185461, -0.893124,
    0.507431,  0.064425,
    0.896420,  0.412458,
   -0.321940, -0.932615,
   -0.791559, -0.597705,
};


struct PS_INPUT 
{ 
    float2 TexCoord : TEXCOORD0; 
}; 


float4 bloomEffect(PS_INPUT Input) : COLOR0 
{ 
    float4 sum = tex2D(samplerState, Input.TexCoord);
    float4 tex;
    
    //accumulate the color values from 12 neighboring pixels
    for(int i = 0; i < 12; i++)
    {
        tex = tex2D(samplerState, Input.TexCoord + mag * offsets[i]);
        sum += tex;
    }

    //average the sum
    sum /= 13;
    
    //fix alpha
    sum.a = alpha;
    
    float greyscale = dot(sum.rgb, float3(0.30, 0.59, 0.11));     
    sum.rgb         = lerp(greyscale, sum.rgb, dessatAmount); 

    return sum;
}



technique Bloom { 
    pass P0{ 
        PixelShader = compile ps_4_0_level_9_1 bloomEffect(); 
    } 
    
}

Any ideas where this is going wrong or why it works fine in vs2010, but not under monogame and vs2012?

Maybe I didn't understood correct what is the problem, sorry.
You can then change a bit code in Activity1.cs

        base.OnCreate(bundle);
        Game1.Activity = this;
        var g = new Game1();
        FrameLayout fl = new FrameLayout(this);

        fl.AddView(g.Window);

then try to use g.Window.SetX and SetY to position it like you want.

Thanks Peter, yes that is Farseer you see there. That part ported over to MonoGame with zero issues, it Just Worked :).

Also, Google offer alpha and beta testing:

So you can publish it privately just to your testers

Viewport won't change windows's position. Its for view in the window.

Oh ok. How silly of me. Thanks!

New Post: Window Position

itafraji — Sun, 19 May 2013 17:35:21 GMT

Ok then try to reset viewport. It is automaticaly set to match yor device screen based on width heigth and aspect ratio. Do it after initialze otherwise monogame will force it back to calculated values. It set it to fit vertically and calculate width by aspect ratio.
This leads to gap on the right side. Try to cteate your own vewport and set it to graphic device. Note that you have to reset it each time the screen size changed. I didn't manage to fix it so I use fullscreen.

To load songs, just use an mp3. No content processing required here.

but what if I don't want a full screen?

New Post: Content pipeline don't work :(

dmitryhryppa — Sun, 19 May 2013 14:06:53 GMT

Fix it! :)

I use 2MGFX. Then load effect like here:

BinaryReader Reader = new BinaryReader(File.Open(@"Content\\shaders\\myShader.mgfxo", FileMode.Open)); 
myShader = new Effect(GraphicsDevice, Reader.ReadBytes((int)Reader.BaseStream.Length));

Maybe it will help some one too...

Thanks!

dmitryhryppa — Sun, 19 May 2013 13:41:13 GMT

Yea, I did this.
And it says: "The MGFX file is corrupt!"...

Note: I use OpenGL Monogame Project

New Post: Content pipeline don't work :(

stephan7 — Sun, 19 May 2013 13:37:46 GMT

You should

copy the myshader.xnb file to the Content folder of your MonoGame project
set it to 'Content' and 'Copy if newer'
Load it with the following code:

    shaderEffect = Content.Load<Effect>(@"myshader");

dmitryhryppa — Sun, 19 May 2013 13:27:59 GMT

Here is what I'm do. 2 ways:

1) Add mysahder.fx to content, and set the content processor to MonoGame Effect.
2) Build it. Have mysahder.xnb
3) Use 2MGFX tool: 2mgfx.exe myshader.xnb myshader.mgfx
4) It says me: "The effect must contain at least one technique and pass."

Second way:
1) Use 2MGFX tool: 2mgfx.exe myshader.fx myshader.mgfx
2) Add myshader.mgfx to content and set content processor as "MonoGame Effect".
3) Try to compile.
4) It says me: "The effect must contain at least one technique and pass."

Not work :(

I try to change "technique" to "Technique", and "pass" to "Pass". But it's not work too...

if I compile myshader.fx, without 2MGFX, with MonoGame Effect processor it's work to create myshader.xnb
But if I tried to load it:

_myShader= Commons.cContent.Load<Effect>(@"shaders/myshader");

It says: The MGFX file is corrupt

stephan7 — Sun, 19 May 2013 13:20:08 GMT

How do you load the effect file (.xnb)?

New Post: Unable to create monogame android project in visual studio 2010 ultimate

slygamer — Sun, 19 May 2013 12:55:16 GMT

MonoGame itself is free, but requires a .NET environment on Android. Xamarin provide the .NET development environment for Android.

New Post: Content pipeline don't work :(

dmitryhryppa — Sun, 19 May 2013 12:20:17 GMT

Thank you! Now it works.
But I have new problem :) With shaders.

I was compile shader like here: http://www.software7.com/blog/custom-shaders-on-windows-phone-8/
And all looks like OK. It make the myshader.xnb for me.

When I try to load the Effect, I get an exception saying The MGFX file is corrupt in MonoGame. The header should be MGFX but it's a seemingly random byte array.

Then I try to use a tool named 2MGFX. I tried this, but the tool reports: __The effect must contain at least one technique and pass. __ From what I can see from myshader.fx the file, it does.

Here is my shader:

sampler TextureSampler : register(s0);
float _valueAlpha = 1;
float _valueRGB = 1;

float4 main(float4 color : COLOR0, float2 texCoord : TEXCOORD0) : COLOR0
{
    // Look up the texture color.
    float4 tex = tex2D(TextureSampler, texCoord);
    
    // Convert it to greyscale. The constants 0.3, 0.59, and 0.11 are because
    // the human eye is more sensitive to green light, and less to blue.
    float greyscale = dot(tex.rgb, float3(0.3, 0.59, 0.11));
    
    // The input color alpha controls saturation level.
    tex.rgb = lerp(greyscale, tex.rgb *_valueRGB, color.a *_valueAlpha);
    
    return tex;
}


technique Technique1
{
    pass Pass1
    {
        PixelShader = compile ps_3_0 main();
    }
}

So, how to use shaders in the monogame? :)
