[1.16.1] Custom tool type?

[VaalAlves]

How would i go about creating a new tool type?
I'm specifically trying to make a tool that would function like a pickaxe but only for certain blocks.
Thanks.

 

Edit:

Use ToolItem and use a Set variable for the effectiveBlocksIn parameter (create the variable before the ToolItem, not during.)

When registering your tool, instead of AxeItem or SwordItem etc. , use ToolItem.

 

Then fill in the blanks.

And how would i make the blocks drop items only if they're broken with said custom tool type?

You could copy the EFFECTIVE_ON field from AxeItem, ShovelItem or PickaxeItem and pass it into the ToolType constructor, or if you're super paranoid like me, use some reflection or AT's to get direct access to the field so you don't have to copy Mojang's code.

I'm having some trouble understanding how the effectiveBlocksIn field of ToolItem works.

I know i'm supposed to put this

private static final Set<Block> field_150917_d_ = Sets.newHashSet(Blocks.WARPED_BUTTON);

(taken from AxeItem)
Here but i'm not sure how.

new ToolItem(0.0f, -2.8f, FossilsAndStuffItemMaterial.CRETACEOUS, /*HERE*/, new Item.Properties().group(FossilsAndStuff.TAB));

 

Thanks for the help.

It's just a parameter, pass it in, but you can't directly reference the one in AxeItem as it's private, if you really don't want to copy it,

I guess my question is more like, what variable type do i use to pass the parameter (since it's my first time working with sets lol).
I've tried HashSet (where i had /*HERE*/ before)

new HashSet(Blocks.OAK_WOOD)

but that doesn't seem to work.
I guess i should also explain completely what i'm trying to do.
I'm adding a couple of blocks that only drop certain resources when mined with this new type tools.
If possible, could you please show me an example of a working ToolItem?
Thanks

Pretty much the same as in AxeItem, edited some stuff to avoid breaching Mojang's copyright. Remember that you need a class that extends ToolItem (at least in 1.15, but I don't think that changed in 1.16).

It seems like you are unfamiliar with Java. Please learn Java before making a mod (generics, inheritance, etc).

I'm not unfamiliar with java, i'm unfamiliar with minecraft modding.

I simply never used sets, never needed them since lists and arraylists exist.

If there was a javadoc, i wouldn't even be making a thread in the first place.

Sets are like arrays and lists, except they don't have an order, don't allow duplicates, and have no "positional" notation.

I'm not sure how you missed that when learning programming, as the comparison between a shopping list and a grab bag should have been made at some point.

My school did it in a pretty stupid way,  for the first year of my course the class was divided in half because there weren't enough computers in any room so those halves got different teachers, mine happened to have been terrible at teaching.

Thanks for pointing it out, made me realize all i had to do was create a variable before creating the tool instead of creating a variable on the spot.

Thanks for all your help, i'll edit my post in case anyone searches with the same question as me.

The HashSet class is filled with Javadoc. I would suggest getting familiar with your IDE.

If you are referring to passing the set into the constructor, then you can pass in a set directly (instead of creating a field). However this depends on if you are going to reuse it.

I do intend on reusing it.
But i meant if forge had (up to date, even 1.15 didn't have them)javadocs though, not HashSet.
Granted, you can just use the "find usages" function but i didn't know about that.
