1.12.2 black background for slideshows

[captainkipn]

I am making a menu and the background I want to be semi animated or like flashy, but when I plug all the code in nothing works and instead gives me a blank black screen. I am using resource loader and the cmm, everything is pretty ok for the most part nothing hasn't worked before but this has refused to work for me
