Pass BlockPos as Param to Item

[Orion31]

Ok, so maybe I'm googling the wrong thing, but I've looked through tons of stuff on NBT and capabilities and I can't seem to figure this out. I have a block that provides the player with 7 "bungee" items that when used will teleport you back to the block you got the item from. However, I can't seem to figure out how to get this to work.

Say my code is this:

i.insertItem(0, new ItemStack(new WaypointBungee(pos), 7), false);

Not only does the item not appear in the inventory, but when I register the item, I have nothing to put as the constructor parameter.

So if I create a method that adds the BlockPos, then I solve the ladder problem but not the former.

How can I make it so that I can add a custom location to this item?

Items are singleton; you cannot just create a new instance of it.

You should create a new ItemStack and save your BlockPos in the NBTTag.

Ok which functions should I use for reading and writing? The docs don't really explain this ?.  Thanks for your help

ItemStack#getTag() and ItemStack#setTag(). Get the tag and if it is null create a new tag. Then populate the tag with your own value(s). Then set the tag if it was null.

Ok but can I call get tag from onItemRightClick? I'm not at a computer rn but when I checked I don't think I could.

Yes you can all you need is an ItemStack instance.
