Hello, I'm trying to make a mod to remove limitation on repair costs in the Anvil. I've Overrided the blocks ANVIL, CHIPPED_ANVIL, DAMAGED_ANVIL I've identified the parts of code I need to change (and changed them): in Repair container I've modified the computation of the cost in RepairScreen I've to change what is written in the label to reflect the cost I'm having a multitude of problems: the anvils are not appearing in the creative menu when I open the gui by right click seems like the game is using the original GUI in creative I can see the cost (with 2 testing books) is 53 (the limit in survival is 39), but if I click to take the output book it disappear each action is performed on the anvil gives a series of errors (that I don't understand quite well) in survival nothing seems changed Is this doable? Could someone help with this? Or could point me on a similar mod that override a default GUI like I want to do? I can post the code if you need it
