Security Cam

From GameStudio Wiki

Thanks to ello for sharing this shader!

Lite-C:

---

Material and function to adjust the effect:

//Security Cam
MATERIAL* SecurityCam_mat =
{
	effect = "SecurityCamPP.fx";
}

function SecurityCam_set_Value(Density,MovementSpeed)
{
	SecurityCam_mat.skill1 = floatv(Density);	//1 looks good
	SecurityCam_mat.skill2 = floatv(MovementSpeed);	// about 3
}

The SecurityCamPP.fx file:

//creates dark lines over the screen

float4 vecViewPort; // contains viewport pixel size in zw components
float4 vecTime;	//contains some time variables
float4 vecSkill1;	//vecSkill1.x is the density of the lines and vecSkill1.y is their movementspeed

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


float4 mainPS( float2 Tex : TEXCOORD0 ) : COLOR0 
{
	float4 Color = tex2D( smpSource, Tex.xy);
	Color *= 0.75 + 0.25*sin((Tex.y/vecViewPort.w-vecTime.w*vecSkill1.y)*vecSkill1.x);
	return Color;
}

technique fx1 
{ 
	pass p1 
	{ 
		PixelShader = compile ps_2_0 mainPS(); 
	} 	
}
