I want to explain this, each line please ... try to understand

texShader = dxCreateShader ( "shader/texreplace.fx" ) 
vehiclelights128 = dxCreateTexture("img/generic/vehiclelights128.png") 
vehiclelightson128 = dxCreateTexture("generic/vehiclelightson128.png") 
  
dxSetShaderValue(texShader,"gTexture",vehiclelights128) 
engineApplyShaderToWorldTexture(texShader,"vehiclelights128") 
  
dxSetShaderValue(texShader,"gTexture",vehiclelightson128) 
engineApplyShaderToWorldTexture(texShader,"vehiclelightson128")

You want to know what each line does?

texShader = dxCreateShader ( "shader/texreplace.fx" ) -- Creates a shader element 
vehiclelights128 = dxCreateTexture("img/generic/vehiclelights128.png") -- Creates a texture element 
vehiclelightson128 = dxCreateTexture("generic/vehiclelightson128.png") -- Creates a texture element 
  
dxSetShaderValue(texShader,"gTexture",vehiclelights128) -- Sets the value of a shader element 
engineApplyShaderToWorldTexture(texShader,"vehiclelights128") -- Applies a shader to one or more world textures. 
  
dxSetShaderValue(texShader,"gTexture",vehiclelightson128) -- Sets the value of a shader element 
engineApplyShaderToWorldTexture(texShader,"vehiclelightson128") -- Applies a shader to one or more world textures.

Solid Thanks I appreciate that, but you could get more in detail - Sets the value of a shading member? I do not understand what you mean

and referred to when he says "gTexture"?

thanx

[Castillo]

Is "gTexture" because the shader you are using assigned that parameter name.

[Brad96]

as I get more information about this parameter?

[Castillo]

Is on your shader file, I really haven't got knowledge about shader scripting.

[Brad96]

the truth, just trying to see how each line to understand

[bandi94]

in the shader file (.fx) is a variable (like a "local value"). That variable is used in the shader to make it dynamic (like the color for the nitro).

So when you call "dxSetShaderValue" it will change the variable. (for the nitro you can pass the color, so when you set greend , the shander will be green, after that you set red =>> the shader will be red.)

In your case is "gTexture" witch in the shader is the .png file you wanna add for the shader (vehiclelights)
