Hey! I want to make a custom Player Animation (like the bow or eat animation). How would I do that? I suppose I have to somehow create a UseAction? Thanks in advance!

Thanks it is working now. I wonder how I didn't find that post.

How do I remove the ore generation?

Hi I want to change the vanilla ore generation. For example I want to make Iron ore more rare (generates lower, in smaller veins and less veins) I have absolutly no idea where to start. Do I have to somehow remove the vanilla generation and add my own or can I just change it somewhere?! I use 1.15.2 but i want to update in the future. Thanks in advance!

Fixed the issue with the GUI not opening ... it tried to access something that was null 🙄 Do not use IInventory (LockableLootTileEntity). Especially because you already have an IItemHandler... I got that from the tutorial series i am watching... he did it the same (i think) Do not use @OnlyIn. What should I use??? You can't do this. There can be multiple people looking at the TE. How should (or should I ?) access the Container??

Hey! I am having an issue with my container and GUI. When I place my Container in the world the GUI works fine. But after a relog I can't open the GUI anymore. Does somebody know why it would do that? Tell me if you need any code! I am using forge 1.15.2-31.2.0 Thanks in advance jmb19905

Ok, I will do that!

Hey! I want to give an ItemStack a cooldown. Currently i am using player.getCooldownTracker().setCooldown(itemIn, ticksIn); but this add a cooldown to the Item (that means that all of the same Item have the cooldown)... I want that only one ItemStack has the cooldown. How would I do that? Thanks in advance!

How would you do that???
