    • I am a beginner and i tried using all the recommendations. Any help or direction to a good example or idea to start this again differently is extremely helpful. I have already tried other methods so rewriting this project  My project is on this branch : https://github.com/Razvan5/MinecraftFoodWorld/tree/workingpot but i also pasted the important classes here. My tile entity is a "pot" that should be able to "boil" my recipes using the fluid determined by the custom recipe but i ran in a major problem: my screen cannot obtain the fluid from my container and i have a hard time remodeling the problem. I use the vanilla ShapedCrafting and AbstractCookingRecipe for the Serializer and the recipes of my pot and an old moded furnace example that seemed much easier for me to modify but create more problems in the long run. Big problems i am trying to fix:  Use IItemHandler instead of IInventory for PotZoneContents Modify PotStateData so i can save non-int data to the NBT Displaying the fluid texture in the screen and all the progress bar with information on percentage (as i made the fluidRegistryName a static string, although useful for testing, I realized way too late why it is a bad idea) The progress arrow or info stops if i implement listeners (methods like addListener() or removeListener() and UpdateProgressBar()) The PotBlock class has too many states for somthing identical NS and WE Change the getters and setters in Abstract Pot Recipe so i only send the registry name of the fluid instead of a fluidstack object Change the transferStackInSlot and validateSlot methods to actually work Display the correct UV texture of the fluid not a stretched out version   What i want to achieve (I do not want to hardcode the fluids)        public class PotContainer extends Container { // stuff for tracking string arrays instead of int? private final List<IntReferenceHolder> trackedIntReferences = Lists.newArrayList();

    • Hi! I am getting the error "Cannot resolve symbol 'DUMMY_UUID'". Minecraft.getInstance().player.sendMessage(msg, Util#DUMMY_UUID); Is it even this how you write it? And the other solution I made is that a good one, or is it bad? //Philip2809
    • You mean a red underline? Yes, it would, but just because it turns red doesn't tell us what your IDE is saying is wrong. All that is is "there is an error here." What error?
    • Did I provide you with the correct things...
    • I solved it, edited me post before, I don't know if I am doing it wrong becasue me DUMMY_UUID turns red? I am doing soemting wrong, but as I did now I got the Entity of the player. //Philip2809
