These videos are so great! I have so many questions about doing more complicated stuff, but looking through the playlist of videos already out, I expect most of them will be answered soon! Up until now, I'd been using MCreator to add modded blocks, which is super easy, but this is already more powerful - if only because of the ability to copy and modify the properties of any vanilla block (which is exactly what I want to do).

[@isniphsi7843]

for newer versions it is the method "ofFullCopy" no longer "copy" so the code for me is in version 1.20.4 Forge 49.0.43 ()-> new Block(BlockBehavior.Properties.ofFullCopy(Blocks.IRON_BLOCK).sound(SoundType.AMETHYST))

Can u make a video if it's np of 3d custom model block hitbox ty

[@HelloThere_General_Kenobi]

Hi, I've been attempting to get started with modding recently, and your videos have been really helpful with speeding up the journey. For some reason though, I can't find any of the classes in the base game inside my project. I saw another video by Whimzee(I coded a minecraft update in 7 days) where you showed them where to find all the classes such as "Magma block". It's supposed to be under "net" and then "minecraft" but I can't seem to find it. Any tips?

[@luigiplayer1547]

hey man i have been trying to change the properties of default minecraft blocks but it as been a nightmare can you help?

[@HolyCrapSpace]

I seem to be struggling. I've rewatched the part of setting up blockstates, models and textures a few times now and I'm certain everything is correct, but when I place my block it's giving me the texture error. It has the texture in my inventory and in the custom tab, just nothing when I place it down

[@HolyCrapSpace]

Edit: I apparently wasn't watching close enough. I accidentally added an s to 'model' in the blockstates file

[@dachidachi231]

hey kaupen will rideable entities come out in the courses if yes then when?

Probably a typo. I had the same issue because i spelled variants varients… so just check everything again and you probably find the mistake

[@Kai_Hallow]

all of my blocks have the texture not found texture both in inventory and when placed, any idea why?

[@ModdingByKaupenjoe]

That usually means there is something wrong with the block model json file. Be it typo, wrong folder etc 🤔

[@IFreedom390]

Kaupenjoe! Thank you for an amazing Tutorial I was wondering will there be a version of this in the paid version where I can rotate the custom block freely based on my direction, like for example like how you place a furnace? Thank you in advance!

[@ModdingByKaupenjoe]

Yes, so in the course there is a custom block model which is also a horizontal block, basically meaning it has a similar style rotation property to the furnace :)

[@Solstici_]

you do that with the block model json file, and works the same way that resource pack custom models do actually. i recommend to get minecraft's assets and take a look at the block model files, specially orientable blocks like wood logs, furnfaces and so

[@GoomyGaming67]

ok if I was making a sand type called black sand it wouldn't be named after and Item How would I register that❔

[@davidlarsson7950]

When using the copy of the iron block, does it not copy the strength of the block? Right now it takes a lot of time for the blocks to break. I understand that I can set it using the strength property, but seems a little weird that's all.

[@MlorenDraymeer]

This is covered in tutorial 5, the game hasn't been told that the correct tool for the block is the pick axe.

[@astralii8887]

Hello, Kaupen! These tutorials are amazing. Though, I am struggling with the error "java.lang.IllegalArgumentException: Cannot get property EnumProperty{name=axis, clazz=class net.minecraft.core.Direction$Axis, values=[x, y, z]} as it does not exist in Block{minecraft:air}" Do you happen to know how to fix it?

[@ModdingByKaupenjoe]

This usually happens if you copy the properties of a block that has certain special properties. So what you likely did is, when registering the block you have () -> new Block(BlockBehaviour.Properites.copy(Blocks.OAK_LOG) or something similar. Try to use a different block to copy the properties from. Maybe planks, stone or something like that. See if that fixes the issue :)

[@astralii8887]

@@ModdingByKaupenjoe That's exactly what I did! Thank you a lot, now it's fixed!

[@RonnieMcDee]

How are you zooming in in the IDE?

[@untrouble8191]

ctrl + "+" or "-"

[@tgnk615gaming]

How do you make a block with a different texture on each side, like a crafting table?

[@lemelangedelevurefarinetea7323]

you need to replace the "all" in the json with a line for up, one for down, one for east, one for north, one for south, one for west, and make all the textures for those sides different images

[@Solstici_]

is it possible to modify existing blocks instead of adding new ones? most of each block's properties can be modified via resourcepacks but aspects like if the block is opaque, translucent or transparent can't. how would that be done?

[@tobihudiat]

For this there are Datapacks and Resourcepacks as you already mentioned! To my knowledge you can change a Blocks property via making a Datapack.

[@mikeonthebox]

Is there a reason for storing the Blocks as RegistryObjects of type Block, instead of the Block themselves? What's the benefit of doing so over storing the Block so we save having to call .get() every time?

[@ModdingByKaupenjoe]

It's basically a Forge thing. That's just how forge does it. One of the reasons is that the registry objects also act as suppliers which means before the get call, if the block isn't registered yet, it's not gonna throw an error. Now, that's a high level overview, but hopefully somewhat more understandable 🙏🏻

[@mikeonthebox]

@@ModdingByKaupenjoeOhh ok. Yes, I also notice that having them that way also allows us to access the getPath for example, used when doing DataGen and some other handy methods too.

[@Andrewww...]

Am I supposed to reload all gradle projects each time I add something?

[@lemelangedelevurefarinetea7323]

nah

[@Nahsh5ba]

That's insane. So much boilerplate code for such simple things. Just compare it to custom blocks in Minetest modding where you can add a new block in ONE line of lua code and that's it.

[@x_Jamez_x]

this is an amazing tutorial but im having the issue of breaking the block of saphire with the same properties as an iron block is taking the same time to break as obsidian i can change it with .strength but that is very inconvenient to do with every block i make

[@IlluminatiJoeCrusade]

I have this same problem, have you been able to fix it?

[@MlorenDraymeer]

That's covered in tutorial #5, the block isn't set to have the pick axe as its tool (that doesnt come from copying the iron block) so the game is treating it as if you are punching the block even when using a pick axe.

[@IlluminatiJoeCrusade]

Thank you, I figured it out, I just needed to add a json file I saw in another tutorial that fixed it

[@maxgagin6671]

@@MlorenDraymeer Thank you very much!

[@Maelanrah]

Hey! Great tutorial ! However, I have a pb with the "Properties.copy" method, to copy the properties from another block. If I try to type it it creates an error; I have "ofFullCopy" proposed instead. If someone knows how to fix it? :)

[@lucasblue2996]

Hey! Not sure if you've already figured it out, but "ofFullCopy" is the new "copy", so you can just use that.

[@alexcevas2099]

Hello, I'm working on my own mod following your tutorials. And I was wondering if there's any way to automate the creation of blocks? Because if I want to implement 15 new blocks, I have to add at least 3 new files and modify two to add them to the tabs for every block wich make like 45 new files. The problem with this is not only that it's very heavy but also that in most cases, I only have to change a name, making it very boring. That's why I have this question. By the way, LIKE!

[@ModdingByKaupenjoe]

Take a look at part 12 "Data Generation". You can automate the JSON files, while for the rest you can "automate" things with some java method, I suggest doing the normal route. 15 Blocks are not that many 🙏🏻

[@alexcevas2099]

​@@ModdingByKaupenjoe Thank you so much.

[@nynx8269]

The block appears in the creative tab with name and all but it has no texture, I've triple check for spelling errors but it is the default purple black texture.

[@joaofelipebald9024]

I know I'm late, but you have to download the texture in the description and paste in "textures\block"

[@sanberdir]

Where tutorial for biomes ver. 1.19?)

[@Jan-gj8bm]

at 4:45 the .copy() doesnt show up but of() does. Did my Parchment not work since there is another command called m_308003 that probably is the copy method.

[@Clurnt]

Hey I'm having this problem too, did you ever figure this out?

[@MlorenDraymeer]

Are you using Minecraft 1.20.4? In later versions they changed the name. Use ofFullCopy() instead of copy()

[@BlainesterSIndustriesYT]

the hardest part is making a good texture lol

[@SATCOMGoose]

I keep getting a bad texture when placing my sapphire_block in the world. It's purple and black I verifed all the json files and can't figure out why the item shows the texture correctly in inventory but not on the actual block when placing it

[@ModdingByKaupenjoe]

If it shows it correctly in the inventory, but not in the world, there is an issue with the blockstates json file. Verify that the folder structure is correct and double check all the spelling and naming of the blockstates json file!

[@SATCOMGoose]

@@ModdingByKaupenjoe I was thinking the same because it shows correctly even if I throw the item from my inventory the only time it doesn't show textures is when placed in the world. I will double check the blockstates json file again but I looked over it and even compared it to the github repo and seems exactly the same.

[@SATCOMGoose]

@@ModdingByKaupenjoe figured it out. It helps when the package is correctly structured. blockstates was under assets and not the tutorialmod directory

[@ModdingByKaupenjoe]

Yep it's due to using 1.20.4. Sadly this entire series is not compatible with anything 1.20.2 and above. So I suggest using 1.20 or 1.20.1 🙏🏻🙏🏻

[@twentyone_cat]

If I were to make a colored block like wool for example, does that mean I'll have to define every block separately, or is there some "correct" way to define them?

[@ModdingByKaupenjoe]

Yes, in theory you'd have to define them each separately, because it might be the case that you'd wanna access the fields individually as well. If that's not really a concern of yours, you can always just make a helper method with a for loop that registers them. But usually I do advise against it 🤔 Later in the tutorials I introduce a way to automatically generate the json files, so that will fall away then. Only the registration of the blocks is needed then 🙏🏻

[@twentyone_cat]

@@ModdingByKaupenjoe I thought about making a loop for it, though if you advise against it I guess it's better to abstain from that. I mostly just wanted to check if I'm not accidentally engaging in some "bad coding practice" lol. I already got the datagens done so that's no concern.

@@ModdingByKaupenjoe new features that require coding

[@ModdingByKaupenjoe]

Right but, we run into the issue again that what about 80% or 90% of people just want to add a few custom blocks, items, entities, machines. Basically expanding Minecraft's base game to a certain extend. Once you go into adding "new features" (so like making Minecraft into a different-ish game) you run into the issue that the landscape of possibilities is so vast, there's different things everyone would want, thus making the tutorials so specific it is only useful to very few people while being way harder to produce. In 1.19 I did a four-part series on a "thirst system" would something like this be what you're referring to?
