[1.12.2] ItemStack question

[FrostBytes]

I'm trying to call a function every tick for each ItemStack that is a type of my Item. How would I do that?

[DavidM]

When? When in the player's inventory? Please clarify.

To call a function every tick when the item stack is in the player's inventory, override Item#onUpdate.

Generally anywhere. Like if it's in a player inventory, or a chest inventory (as long as it's loaded) or on the floor?

In this case you need to use different method fr each. I don't think this is possible with the chest inventory though (in which case you have to create your own chest).

As for on the floor, override Item#onEntityItemUpdate.

What do you want to achieve? There might be other ways to achieve what you want.

Would it be possible to override functionality of the vanilla chest from the mod?

It could be done, but would be a bad idea. You might as well create your own chest that has your custom functionalities.

You can take a look at the code of the alchemical chest in ProjectE, which does exactly what you described (allow custom items update inside chest).

You also can't do anything about inventories that aren't loaded.

If you're trying to do something that changes at a constant rate over time, you can do it using timestamps.  What exactly is the goal?

I’m trying to run code every tick for every itemstack currently loaded.

That much is obvious. What will this achieve for an end user perspective?

It's going to just be code that randomly checks if there is a certain container nearby and move the itemstack into it. Not sure how that would contribute to this.

Because there are better ways of doing this than the one you’re trying. For example, putting the item into the container from the container. This is super easy if the container has something that runs every tick (like an Entity or a TileEntity).

What you’re trying to do is always relevant, because there’s usually a better way of doing it.

Wow. Never really thought of that. Thanks.
