Water Shader Toggle

[h4x7o0r]

Hey all , i want to make a toggle for water shader ( E.g When i press "K" button to turns the shader on / off ).

Here is the code :

     
toggle = false 
function water() 
  
        -- Version check 
        if getVersion ().sortable < "1.1.0" then 
            outputChatBox( "Resource is not compatible with this client." ) 
            return 
        end 
  
        -- Create shader 
        local myShader, tec = dxCreateShader ( "water.fx" ) 
  
        if not myShader then 
            outputChatBox( "Could not create shader. Please use debugscript 3" ) 
        else 
            outputChatBox( "Using technique " .. tec ) 
  
            -- Set textures 
            local textureVol = dxCreateTexture ( "images/smallnoise3d.dds" ); 
            local textureCube = dxCreateTexture ( "images/cube_env256.dds" ); 
            dxSetShaderValue ( myShader, "microflakeNMapVol_Tex", textureVol ); 
            dxSetShaderValue ( myShader, "showroomMapCube_Tex", textureCube ); 
  
            -- Apply to global txd 13 
            engineApplyShaderToWorldTexture ( myShader, "waterclear256" ) 
  
            -- Update water color incase it gets changed by persons unknown 
            setTimer(   function() 
                            if myShader then 
                                local r,g,b,a = getWaterColor() 
                                dxSetShaderValue ( myShader, "gWaterColor", r/255, g/255, b/255, a/255 ); 
                            end 
                        end 
                        ,100,0 ) 
        end 
    end 
  
     
addCommandHandler("water", water) 
  

Where should i put the "if statement for the toggle" and bind button

Line 29 : Bad Argument @ 'engineApplyShaderToWorldTexture' . [Expected material at argument 1, got boolean]

Copy my code again, I forgot about something.

Now everything's fine. Thank you very much.

[Castillo]

You're welcome.

How can I set this to be active when the resource starts ?

Like always Castillo to the rescue. Thank you very much man . It's working very well.
