How do you make items swap?

[AndPherb]

I want to make a pickaxe that gets progressively weaker as you use it. I learned I needed to create several versions of the pickaxes, but I don't know how to make the pickaxe swap out for an identical pickaxe with the same wear.
If someone could help, that would be nice.
Thank you!

There's set_tool_capabilities nowadays, so you don't need to register several picks.
For wear there's set_wear.

As I understand it, AndPherb wants a pickaxe that can crack very hard materials but after some time when it was worn, it cannot do that anymore.

Can we set tool capabilities via ItemStack metadata? Then this could be possible by writing a function in after_dig_node that checks wear value and adjusts the tool capacities accordingly.

Edit: Just checked. Yes, is possible.

Code: Select all

`ItemStackMetaRef`
------------------

ItemStack metadata: reference extra data and functionality stored in a stack.
Can be obtained via `item:get_meta()`.

### Methods

* All methods in MetaDataRef
* `set_tool_capabilities([tool_capabilities])`
    * Overrides the item's tool capabilities
    * A nil value will clear the override data and restore the original
      behavior.
[...]

So this would be the way to go. Add an after_dig_node function that checks the wear level and sets the tool capabilities as ItemStack metadata.

(And btw. that’s actually a cool idea!)
