GetColorFilter

From Multi Theft Auto: Wiki
Jump to navigation Jump to search

This function is used to get the values of color filtering.

[[{{{image}}}|link=|]] Tip: Normally the game is adding these colors to a screen to simulate weather effects. Sometimes it can be important to disable these effects. You can get rid of the effects by calling setColorFilter with zero values.

Syntax

int, int, int, int, int, int, int, int getColorFilter ( bool isOriginal )

Required Arguments

  • isOriginal: A bool indicates if the return values of color filter are GTASA original or changed by setColorFilter. If this is set to false, the return values would be the color filter that is currently being used.

Returns

Returns 8 integers, of which the first 4 indicate the color (R,G,B,A) of color filter A, and the last 4 indicate the color (R,G,B,A) of color filter B.

Example 1

This example corrects color of dxDrawMaterialLine3D. But this method has some limit. 

local testRT = dxCreateRenderTarget(32,32,true)

x,y,z = 0, 0, 4
size = 4
addEventHandler("onClientRender", root, function()
	dxSetRenderTarget(testRT,true)
	dxDrawRectangle(0,0,32,32,tocolor(255,255,255,255))
	dxSetRenderTarget()

	local aR,aG,aB,aA,bR,bG,bB,bA = getColorFilter(false)							--Get current color filter
	local cR,cG,cB = 127/255+(aR*aA+bR*bA)/65535*0.5, 127/255+(aG*aA+bG*bA)/65535*0.5, 127/255+(aB*aA+bB*bA)/65535*0.5	--Calculate the result color of color filter
	dxDrawMaterialLine3D(x+size, y+size, z-0.95, x-size, y-size, z-0.95,false, testRT, size*2,tocolor(127, 127, 127, 255))
	dxDrawMaterialLine3D(x+size+20, y+size, z-0.95, x-size+20, y-size, z-0.95,false, testRT, size*2,tocolor(127/cR, 127/cG, 127/cB, 255))
end)

Example 2

This example corrects color of dxDrawMaterialLine3D using shader 

local shader = [[
float3 colorFilter = float3(1,1,1);
texture sourceTexture;

sampler2D SamplerTex = sampler_state{
    Texture = sourceTexture;
    MipFilter = Linear;
    MinFilter = Linear;
    MagFilter = Linear;
    AddressU = Mirror;
    AddressV = Mirror;
};

float4 colorFilterRemover(float4 color:COLOR0, float2 UV:TEXCOORD0) : COLOR0{
	color *= tex2D(SamplerTex, UV);
	color.rgb /= colorFilter;
	return color;
}

technique cFilterRemover{
	pass P0{
		PixelShader = compile ps_2_0 colorFilterRemover();
	}
}
]]

local cFilterRemover = dxCreateShader(shader)
local testRT = dxCreateRenderTarget(32,32,true)
dxSetShaderValue(cFilterRemover,"sourceTexture",testRT)

x,y,z = 0, 0, 4
size = 4
addEventHandler("onClientRender", root, function()
	dxSetRenderTarget(testRT,true)
	dxDrawRectangle(0,0,32,32,tocolor(255,255,255,255))
	dxSetRenderTarget()

	local aR,aG,aB,aA,bR,bG,bB,bA = getColorFilter(false)							--Get current color filter
	local cR,cG,cB = 127+(aR*aA+bR*bA)/255*0.5, 127+(aG*aA+bG*bA)/255*0.5, 127+(aB*aA+bB*bA)/255*0.5	--Calculate the result color of color filter
	dxSetShaderValue(cFilterRemover,"colorFilter",cR/255,cG/255,cB/255)					--Apply to the color filter remover shader
	dxDrawMaterialLine3D(x+size, y+size, z-0.95, x-size, y-size, z-0.95,false, cFilterRemover, size*2,tocolor(127, 127, 127, 255))
	dxDrawMaterialLine3D(x+size+20, y+size, z-0.95, x-size+20, y-size, z-0.95,false, testRT, size*2,tocolor(127, 127, 127, 255))
end)
