Simple Blur

From GameStudio Wiki

Lite-C:

---

Material and function to adjust the effect:

// Blur in all directions (Lowquality)
MATERIAL* SimpleBlur_mat =
{
	effect = "simpleBlur.fx";
}

function SimpleBlur_set_Value(Blur)
{
	SimpleBlur_mat.skill1 = floatv(Blur);	// should be higher than 1
}

The simpleBlur.fx file:

//////very simple blur in each direction//////

texture TargetMap;

float4 vecSkill1;

sampler postTex = sampler_state
{
   texture = (TargetMap);
   MinFilter = linear;
   MagFilter = linear;
   MipFilter = linear;
   AddressU = Clamp;
   AddressV = Clamp;
};

float4 SimpleBlur_PS( float2 Tex : TEXCOORD0 ) : COLOR0
{
	float4 Color;

	Color = tex2D(postTex, Tex.xy);
	Color += tex2D(postTex, Tex.xy+0.001*vecSkill1[0]);
	Color += tex2D(postTex, Tex.xy-0.001*vecSkill1[0]);
	Color /= 3;

	return Color;
}

		PixelShader = compile ps_2_0 SimpleBlur_PS();
