Cancel block place

[maiden flame]

Check out UseBlockCallback. If that doesn't work (it might have to be server-side, idk), feel free to copy the mixin from my mod here and modify it to check for name instead of custom model data.

It should work for 1.20-1.20.4, and there's branches going down to 1.15.x if you're going that low

thx

[maiden flame]

@past spindle Are you trying to stop from placing a specific block, rather than just the name? If so, check what type the block is. No need to try and check names.

[past spindle]

i already fixed the problem, but thank you

there's actually a pumpkin with lang name

that why it's like an item

[maiden flame]

Not sure what you mean by that, but it's a lot safer (and probably faster) to just check if it's a pumpkin rather than testing if it's named "Pumpkin" in the same language. Especially if someone renames the item.

[past spindle]

if i use just pumpkin, i can't place just pumpkin

and, do you now how to ignore capslock in string?

[maiden flame]

String#toLowerCase or something like that

Then you compare with a lower case string

@maiden flame

sorry for asking again, but idk why this is again not working, if you have time, can you help me?

if (stack.getName() == null || !equalsIgnoreCase((stack.getName().toString()), (Text.translatable("item.cherrytown.gold_cherry_vision").toString()))){ return true; } else if (stack.getName() == null || !equalsIgnoreCase((stack.getName().toString()), (Text.translatable("item.gold_cherrytown.gold_cherry_vision").toString()))){ return true; } else if (stack.getName() == null || !equalsIgnoreCase((stack.getName().toString()), (Text.translatable("text.gold_cherrytown.gold_cherry_vision").toString()))){ return true; }

its comparing to string with equalsignorecase

no errors in ide*

if its identical no matter capslock, then true

so its reversed

and if item its not that = true

[maiden flame]

So you're trying to prevent yourself from placing everything except this gold_cherry_vision thing, right?

[past spindle]

include*

[maiden flame]

Ok, so only that? First off, you're trying to compare a strings for the objects, not the strings that are the names. Second, that's a strange way of doing it - you're making a lot more work for yourself.

Next, I don't know where equalsIgnoreCase came from, that's an instance method in String, but I suppose that doesn't matter since we don't need it.

You're needing stack.getItem().equals(*/ Wherever your item is*/.*/ITEM_NAME*/)

[past spindle]

That's all?

[maiden flame]

Yep.

How much java experience do you have?

2 days 💀

OK, well there's your problem :P

Here's some good resources to help you get started

Minecraft modding is a really hard place to start

!!learnjava

[velvet patrol]

To start modding Minecraft using Fabric, it's strongly recommended to know Java.
Minecraft, in its codebase, and mods, using Fabric API, use more advanced Java concepts like lambdas, generics and polymorphism.
If you don't know all of these concepts, you may have some difficulties modding.

Here are some online resources that will help learning Java
JetBrains Academy (free online course): https://www.jetbrains.com/academy/
Codecademy (free online course): https://www.codecademy.com/learn/learn-java

After Learning Java
For most mods you will want to make, you will have to use the Spongepowered Mixin Java library.
To learn more about Mixin, you can use the faq/mixin bot tag by typing !!faq/mixin in #bot-posting .
