Orion31 Posted August 24, 2019 Posted August 24, 2019 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? Quote
DavidM Posted August 24, 2019 Posted August 24, 2019 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. Quote Some tips: Spoiler Modder Support: Spoiler 1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code. 2. Always post your code. 3. Never copy and paste code. You won't learn anything from doing that. 4. Quote Programming via Eclipse's hotfixes will get you nowhere 5. Learn to use your IDE, especially the debugger. 6. Quote The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it. Support & Bug Reports: Spoiler 1. Read the EAQ before asking for help. Remember to provide the appropriate log(s). 2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

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.
