[1.12.2]Modding: Item the opens a GUI when right-clicked

Posted May 1, 20196 yr

So, I need a way to create an Item that when right-clicked, opens an inventory. The inventory Needs to store a special only a special type of item. Is there a tutorial that explains this?

Attach an IItemHandler capability to your item.

Then, create a GUI (and a container) for the item's inventory and open it in Item#onItemUse.

You can create a custom Slot class and override the canAccept (can't remember the spelling) method to check if the ItemStacks to be inserted match your criteria and use it as the slots in your container.

Some tips:

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TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.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.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

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.

I'm not finding the canAccept method, and I'm not sure how to create a GUI.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated

Bad pathfinding for big mobs (1.21.1)

I've struggled with this for way too long now, so I have decided to ask for some assistance here because there is almost no information about this online.

I made a hostile mob and I built it like this:
public static final Supplier<EntityType<Bunyip>> BUNYIP = ENTITY_TYPES.register("bunyip" , () -> EntityType.Builder. of(Bunyip::new, MobCategory.MONSTER).sized(3f, 2.5f).eyeHeight(1.75f).build("bunyip"));

However, I have discovered that a BoundingBox of 3 is too big for the vanilla pathfinding to work well. In fact, anything bigger than a block will not work well. This is especially noticeable when having it chase a player in a negative X and/or negative Z direction. The mob starts spinning, walking backwards, walking diagonally, etc.

I am using the Goal system:
protected void registerGoals() { super.registerGoals(); this.goalSelector.addGoal(1, new MeleeAttackGoal(this, 1.25, true)); this.targetSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, Player.class, true, true)); }

This does not seem to be a me issue as the ravager, one of the biggest vanilla mobs, also struggles with proper pathfinding. I am a bit familiar with how Minecraft's pathfinding works, but not enough to make a pathfinding system from scratch (or at least not in a reasonable amount of time). Is there any way to fix this with some tweaks or will I have to make a custom pathfinding system?

New Forum Design/Update: Issues and Suggestions

Unfortunately, it seems that Invision has decided that everything is locked down and no longer customizable.
Their attitude to anyone who wants to edit anything is 'Just accept it we know best and screw you for even insinuating that you want to customize your own site'
So there isn't much we can do about the layout of actual features.
Best bet for the editor is that psudo markdown works, so typing ` around words make code blocks.
Only options is to start writing bespoke modifications to the forum's php code itself, which I really don't want to do.
I would of stayed on v4 but the version of PHP that it supports is going EOL and Invision has stated they have no intentions of upgrading it.
They also removed the central community for finding plugins/community addons.
Overall it is my feeling that they are intentionally trying to kill off self-hosting communities by removing features and locking things down, in an effort to force everyone into using their paid hosting services.

My HOPE is that someone in the overall forum community will write an exporter for Invision to something like SMF. Which is what we were originally on before old team members decided enterprise software is better.
