Oldscool

From GameStudio Wiki

Thanks to ello for sharing this shader!

Lite-C:

---

Material and function to adjust the effect:

//Oldscool
MATERIAL* Oldscool_mat =
{
	effect ="Oldscool.fx";
}

function Oldscool_set_Value(Pixelation_x,Pixelation_y)
{
	Oldscool_mat.skill1 = floatv(Pixelation_x);	//100 looks good
	Oldscool_mat.skill2 = floatv(Pixelation_y);	//should be the same as above
}

The Oldscool.fx file:

//Makes the game to look as if it had a very low resolution

texture TargetMap;
sampler2D smpSource = sampler_state { texture = <TargetMap>; };

float4 vecViewPort; 
float4 vecSkill1;

float4 blockyPS( float2 Tex : TEXCOORD0 ) : COLOR0 
{
	Tex.x = round(Tex.x*vecSkill1[0])/vecSkill1[0];
	Tex.y = round(Tex.y*vecSkill1[1])/vecSkill1[1];
	return tex2D(smpSource,Tex.xy);
}

technique postFX 
{ 
	pass p1 
	{ 
		PixelShader = compile ps_2_0 blockyPS(); 
	} 
}

technique fallback { pass one { } }
