Someone Get Up There And Fix The Antenna!

I broke your mugen TV.

This is simply a proof of concept. Download the file and make sure you have a backup of indexed.frag in your data folder before replacing it!

Ohhh... pixel shaders.
Could be handy... if you could call them at specific moments.

Could you explain what it is? How to use? I have no clue WTF this is.

It's a fragment shader that modifies the colors of indexed sprites to greenscale.

Ok how do I use it? Is it 1.0 or 1.1, opengl?
Its cool what you did, any way to change the color?

The file is written in GLSL

Go down to the bottom and you'll see the main program and where I've made a modification

Code:

void main()
{
  vec4 color = nearest();

#if !defined(PALFX_DISABLE)
  palfx(color);
#endif

	float grayval = 0.21*color.r + .71*color.g + .07*color.b;
 
  gl_FragColor = vec4(0,grayval,0,color.a);
}

nearest() is a function defined earlier in the file that determines which color of the palette (sampler1D texunit1) to use for the current pixel.
palfx() is the function defined that executes all of the palfx stuff you coded into your character.

gl_FragColor is the variable which the shader returns after the code has finished running. Here I've calculated a weighted average based on the color I was going to use, and instead used that value as the green channel for the final result. I've zeroed out red and blue, and copied the alpha value from the original result.

Unfortunately mugen currently does not employ the use of a full screen shader. This means that messing with the vertex shader is pretty much off-limits.

File is embarassingly small so indexed.vert is in its entirety here

Code:

#version 120

void main()
{
	vec4 foo = gl_Vertex;
	foo.x *= .5;
	foo.y *= .5;
	
  gl_TexCoord[0] = gl_MultiTexCoord0;
 
  gl_Position = gl_ModelViewProjectionMatrix * foo;
}

Ok here's something of substance.

This shader will color the outlines of sprites black.

If you’re gonna reach for a star...
reach for the lowest one you can.

Wow, this is pretty cool.

Almost fixed my TV.

Too bad there's no way in GLSL to generate a random seed number

So, this are image renderers for mugen?? or something coded into a character?? I´m pretty clueless with this but I gotta say it´s pretty interesting. The cartoon outline is pretty cool.

I removed a line of code that elecbyte wrote to hackishly fix that. I shouldn't have.

Edit: Fixed
Edit2: AAAAAAAAAAA fixed for real

Is it possible to use Doubleres=2 like in winmugen but in mugen 1.0 and above using this tool?))

You can't do that already?
Also, no. That requires using the vertex shader.

I love the cartoon shader its awesome! the only thing that bugs me is that it traces shadows and
some things that should be transparent like rays of light.
other than that i love it. BTW is this only for 1.1? i was gonna use it in
Capcom vs the World but didnt see the frag files in the data folder.
some pics for the hell of it.
