[SHADER] Problem

[ma2med]

Hello, I have this shader script :

texture Tex0; 
float red; 
float green; 
float blue; 
float alpha; 
      
technique hello 
{ 
    pass P0 
    { 
    Texture[0] = Tex0; 
    MaterialAmbient = float4(red, green, blue, alpha); 
    } 
} 

When I put color values and texture it works but if I put only colors values it's making it completely black or white.

  
-- Working example 
dxSetShaderValue(shader, 'Tex0', texture) 
dxSetShaderValue(shader, 'red', r) 
dxSetShaderValue(shader, 'green', g) 
dxSetShaderValue(shader, 'blue', b) 
dxSetShaderValue(shader, 'alpha', a) 
engineApplyShaderToWorldTexture(shader, 'texture', element) 
  

  
-- Not working example 
dxSetShaderValue(shader, 'Tex0', nil) 
dxSetShaderValue(shader, 'red', r) 
dxSetShaderValue(shader, 'green', g) 
dxSetShaderValue(shader, 'blue', b) 
dxSetShaderValue(shader, 'alpha', a) 
engineApplyShaderToWorldTexture(shader, 'texture', element) 
  

Please help me with this issue

You may need to set the texture state 0 to its default value instead of simply nil'ing it. To get the default texture for a certain state, use this (copied straight away from mta-helper.fx):

texture gTexture0           < string textureState="0,Texture"; >; 

If you don't want your object to have a texture, you will probably need to create a dummy one which is all white or something like that.

Yes, this is what I wanted to do Thanks for the answer but I don't know where to put it, I tried to set Tex0 value to 0 but it's not working.

I don't really know how to help you further properly. I could tell you what experiments I would do, but providing that HLSL documentation out there is rather misleading and that I do not have an advanced knowledge of the language I think that letting a more experienced person help you is more appropiate, unless you want to try countless modifications to your code until we find a working solution that will probably be not very efficient.
