@clowcadia Please explain in detail what you want to do, how everything works right now and why you think you should do what you're thinking of and how you think of doing that.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

Ok so i have a livingEntity that has a stomach value, and a container with a gui. when i inset food in one of the container slots eat consumes the item and increases the stomach value. what i am trying to do is display the value in the gui as it consumes the food. the problem i ran into is that the value display does not increase in the gui unless i re-open the gui. i was able to make the gui update its value with the stomach value as static but the problem is when i reload the world that value resets to 0 where it normally stays the same due to read/write to NBT

You synchronize the value into the gui using the IContainerListener interface. You can see an example of how to use it in ContainerFurance.

This is because your entity doesn't save the value to NBT correctly (probably). Once you have implemented the gui-syncing using the method I described above and this is still an issue, post your full entity class.

Its only when the value is static for stomach.

in the container override detectAndSendChanges check if the value is not the same on the server and the client is not send a packet

look in ContainerFurnace how mojang does it

How exactly do I access. When I was accessing with (basic) entity.get stomach() it would not react when I had it used as an integer added to a string

Try also overriding Container#updateProgressBar(int, int).

Minecraft crashes when trying to start singleplayer/create new world.

I've been trying to get an old modpack of mine working again (MC version 1.20.1, Forge version 47.4.8) & I finally got it to just load into the homescreen. Unfortunately, now its crashing whenever I try to start Singleplayer, specifically when its trying into the Create a New World screen. I've attached the latest Crash Report, though if that alone isn't enough I can also attach the Log in a comment. If anyone can help me figure out what's causing the issue I'd really appreciate it.
