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

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

 getColorFilter ( )

Code Examples

Example 1 Example 2

client

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)

client

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)
