I am new to Modding, attempting to create my first mod while following along with Direwolf's Mining Gadgets. I've run into abit of a snag, however, and can't seem to find a solution. So, I'm creating a block that has a GUI and I've got it showing, but it is not matching up to where the container slots are. I've tried messing with the relY to move it upward and had it matching up, but when moving it over to my second monitor, it offsets once again. I'm not sure what exactly I'm doing wrong, as I've been following Dire's mod as well as watched McJty's tutorial on making the GUI, and theirs works perfectly fine when running. I would post my code here, but I'm not sure of specifics on how to go about that in the correct way. For now, I will include a link to my GitHub repository. Any help would be appreciated.
