SetObjectShaderConstantByName()
Oh wow how could I miss this command

I once made my own solution for that problem with drawobject()
Would love to know how Paul solved it !?

Thanks MikeMax
And I guess...yes there should be SetObjectMeshShaderConstantByName() and SetSpriteShaderConstantByName() then

For your problem...lets see
Hm there is no command for drawing the mesh or setting it invisible
Maybe you create a temporary mesh/object with your shader which you draw over the other object/mesh right before you render the scene

2. Fog activation make the shader to throw an error with the agk_CameraPos declaration (previously declared ? i don't see where)

I have already answered this question here (some posts above).

1. with animated models, when the normal shader is applied, animations no longer works

This is a similar problem to the fog. The animation is realized with a shader. If you use your own shader, then you override the automatically generated code.
A solution would be to write your own code for the bone animation. Or intigrate the existing code in the normalmapping shader.

Here is the standard code that agk generate.

+ Code Snippet

attribute highp vec3 position;
attribute mediump vec3 normal;
varying highp vec3 posVarying;
varying mediump vec3 normalVarying;
varying mediump vec3 lightVarying;
mediump vec3 GetVSLighting( mediump vec3 normal, highp vec3 pos );

uniform highp mat4 agk_ViewProj;
attribute highp vec2 uv;
varying highp vec2 uvVarying;
uniform highp vec4 uvBounds0;

attribute highp vec4 boneweights;
attribute mediump vec4 boneindices;
uniform highp vec4 agk_bonequats1[30];
uniform highp vec4 agk_bonequats2[30];

highp vec3 transformDQ( highp vec3 p, highp vec4 q1, highp vec4 q2 )
{
    p += 2.0 * cross( q1.xyz, cross(q1.xyz, p) + q1.w*p );
    p += 2.0 * (q1.w*q2.xyz - q2.w*q1.xyz + cross(q1.xyz,q2.xyz));
    return p;
}

void main()
{ 
    uvVarying = uv * uvBounds0.xy + uvBounds0.zw;
    highp vec4 q1 = agk_bonequats1[ int(boneindices.x) ] * boneweights.x;
    q1 += agk_bonequats1[ int(boneindices.y) ] * boneweights.y;
    q1 += agk_bonequats1[ int(boneindices.z) ] * boneweights.z;
    q1 += agk_bonequats1[ int(boneindices.w) ] * boneweights.w;
    highp vec4 q2 = agk_bonequats2[ int(boneindices.x) ] * boneweights.x;
    q2 += agk_bonequats2[ int(boneindices.y) ] * boneweights.y;
    q2 += agk_bonequats2[ int(boneindices.z) ] * boneweights.z;
    q2 += agk_bonequats2[ int(boneindices.w) ] * boneweights.w;
    highp float len = 1.0/length(q1);
    q1 *= len;
    q2 = (q2 - q1*dot(q1,q2)) * len;
    highp vec4 pos = vec4( transformDQ(position,q1,q2), 1.0 );
    gl_Position = agk_ViewProj * pos;

    normalVarying = normal + 2.0*cross( q1.xyz, cross(q1.xyz,normal) + q1.w*normal );
    posVarying = pos.xyz;
    lightVarying = GetVSLighting( normalVarying, posVarying );
}

I hope it helps.

Really hope to get a 3d shadow system(free or paid)

Yes, it's a real need for me too !

The janbo's 3D shadow shader is a great good start but unstable and unusable actually in a "real" 3D environment for the moment.

And we need multiple pass shaders system to combine multiple shaders only when necessary (or an AppGameKit system to compile this "all-in-one shader" at project compilation according to object/mesh options (Bones animation + fog + 3D Shadow casting + normal/spec mapping + lightmapping... it's just an example of a real need !) .

+1. I dont mind if the community is selling plugin those features. But if it is support officially, agk features advertisement will look great

yeah I think AppGameKit should at least include the default tested on all platform shaders.
so we get a head start and adjust and create extras but the default is a must.

Thanks for your DOF shader ....
But could you put a small 3d example please ... sorry .. I'm very noob

@GolWofael the shader is really a simple tilt shift shader applying blur to the full screen, but increasing the magnitude of the blur the further away from the middle of the screen (in the y axis) the pixel is.

It's not a true DOF shader.

Anyone wanting to learn shaders, I have found a great online book which has links to editors etc:

Might be useful

Text string, Image Buffer, Sprite Effect:

With different settings in the shader, you can get a lot of variations

// This one builds a starfield:
const float maskStr = 0.0125; // 0.0 - 1.0
const float vignetteStr = 0.0002; // 0.0 - 1.0
const float crtBend = 20.8;
const float crtOverscan = 0.21; // 0.0 - 1.0

Excellent Shaders Jack

And I believe baxslash 2d for the additive code

I modified the Lensflare and snow shaders by jack and added an additive blend of the background image rather than just use the noise this created
a background that could have a sun scroll down in the background adding a colour blend to the background sprite. Great for what I wanted a sunset
in 2d without the use of a quad image. I didn't change all that much to baxslashes awesome lensflare but now it does what I wanted and I have
commented the changes.

The summer.png that I use can be any 2d background image

Ive been playing around with Blendmans texture blending code as I was hoping with modifications the gl_FragColor could be used to output a morphed texture

+ Code Snippet

gl_FragColor = (texture2D(texture0, uvVarying) + texture2D(texture1, uvVarying))/2.0;

I believe averages the color between texture0 and texture1
so I end up with an image 50percent texture0 and 50 percent texture1.(correct me if I'm wrong but that's what I think I'm seeing)
my question is how could I add and averaging factor in the following so that it might morph 10percent if chosen 20percent or even 100 percent and totally replace
with the second texture

SetWindowSize( 1024, 768, 0 )

you could alter this line

WriteLine(file,"gl_FragColor = (texture2D(texture0, uvVarying) + texture2D(texture1, uvVarying))/2.0;")

This is where it's sets the 50% blend between each pixel colour.
