Hey Everybody! Haven't asked any questions lately - So I've got a good one

Im trying to add a postprocessing shader to my game, but i just can't get it to work..

I've created the .fx file - and added the proper script to my main script.

then the rest I tried to fill in... So i added this to my main script:

function main(){

ScrachedFilm_set_Value(0.01);
...
}

and that didnt work. So Im really not to sure what to do from here.

Any thoughts?

(Here is the link to the shader)

Did you remember to assign the material?

what would i be assigning it to?
Keeping in mind that i am using c-script.

Some functions are missing. "PP_Init_Effect()", "PP_Toggle_OnOff()" etc.. Solution is here. (Slin's demo)
