Yeah, a lot has indeed changed! Here's a link with some of the stuff that changed, it's been quite helpful for me: https://gist.github.com/williewillus/353c872bcf1a6ace9921189f6100d09a it also has links to other resources for things that changed/1.15 changes. Good luck! **And don't feel bad about "bothering" people here, that's what the forums are for. There's no shame in not knowing something as long as you're asking the right questions/accepting advice where applicable, providing requested information, things like that, you're all good

Yes, for the most part you must use mods for the version of minecraft/forge you are running, and others will not work and likely cause the game to crash. There are sometimes exceptions, depending on the mod, where i.e. a 1.15.1 mod will run on 1.15.2, but I have not tried doing this myself, and cannot promise any compatabilities doing that

Also make sure you are downloading the installer from https://files.minecraftforge.net/ and not the launcher.

Well, I guess I can't speak for Microsoft/Mojang about what they support, but forge no longer provides support for any version lower than 1.14, there are just too many versions to support the old stuff, and the majority of the developers are focusing their efforts on current stuff. That being said, you can still use it, but if you have problems you'll have to either figure it out on your own, or look for help elsewhere.

Really old versions are no longer supported. Please update to a modern version to receive support. More information on supported versions can be found in the LTS link at the top of every page.

I don't use IntelliJ, but in Eclipse there's a folder in my project/package listing for "Referenced Libraries", and within there is a forge jar that contains the minecraft/forge code, and a client-extras jar that contains the assets like the jsons and such. *edit: Oh, and don't listen to anyone giving you crap about your graphics. There are PLENTY of mods (and lots of popular ones included) with crappy graphics. Not that good images aren't cool, but don't let that stop you IN ANY WAY (including publishing to curseforge) from continuing/finishing your mod, because the fun and creativity your ideas bring to the game are MUCH greater than any stupid images will!

I think we need to go back a step, and have you describe what you are trying to accomplish, from a gameplay (not programming) point of view. Then knowing what the actual question is, we can find a suitable answer

Yes, (well, they don't HAVE to) but you are creating it twice as diesieben mentioned, once in the items registry event, and then once in your moditems. I was pointing out the one in ModItems you are using new Item() instead of new BlockItem(), but honestly you should probably just remove that one entirely, since you already create your blockitems in a loop in the item registry event. You should take a step back, I notice you have a LOT of code for having a broken block, which leads me to believe you've been doing a lot of copy & pasting. If you must copy & paste, only do small pieces of code at a time, to make sure they work, and to attempt to understand them as much as possible before moving on.

Do you have Java? If so, then you should google jarfix and download/run it to fix your jar file associations. If not, download java 8 hotspot from https://adoptopenjdk.net/

I'm not sure, but you make your blockitem (in ModItems) an Item, and not a BlockItem. Could that be the issue?

1. change your modid, make it longer and it cannot contain capital letters 2. all those places that should be your modid, make them be your modid, instead of random things that are similar to your modid.

Your modid still contains capital letters. Also, you aren't using the same modid throughout your mods.toml and code. in one place in another and another

Screenshots are a terrible way to share code, you should share using a github repo, or using the code tags (the <> above when you post a msg) That being said, I can just see enough from the screenshots to see you still have capital letters in your modid.

Your assets folder needs to be assets/MODID you have assets/mlm but your modid is minerslifemod *edit: make sure when you make changes, to push updated code, as well as post updated logs.

The json has nothing to do with the error. (*edit: besides the modid being wrong because it's caps) The error is because he's using caps in his modid. He showed a blockstate, and you posted a model, they're 2 different things for 2 different purposes.

I would not use a ! in your file paths. Try changing that, and see if it makes a difference.

I would use the latest MDK, not the recommended, there is new improvements and newer mappings in the latest. Please post the debug.log

Which version of Java did you get? You want Java 8. Also, it looks like you may have gotten 32 bit Java, and you definitely want 64 bit.

Please provide details, as well as your debug.log

https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e has some info on 1.15 changes

1.12 is no longer supported due to age. Please update to a modern version (1.14.4/1.15.2) to receive support. More information on supported versions can be found in the LTS link at the top of every page.

I would guess that there is an adblocker or antivirus stopping the page from loading. In the list of all versions, there should be a small "i" to give you a direct download link if you must.

I couldn't tell you, but that is irrelevant. It has been made clear on this site that only the current and previous version are supported, and threads for outdated versions get locked by moderators, as they clutter up the forums for the people looking for help with the current versions. You're free to continue using outdated versions (much as someone could install and use Windows XP on their computer), but you will not receive support here for it (much like if you asked Microsoft for support for Windows XP; they would tell you to update). *edit: not to mention staying in the past, you miss out on new stuff, for example, being able to use VSCode out of the box. . . .
