Let me apologize first, I didn't mean to make it sound like you guys wouldn't know about this already! I tried to skim the forums for a little but stopped after page 2 of the search results 😅. However, I wanted to write down my process of thought so that any other curious User, who has wondered about the same things, might stumble upon this one day. That is, by the way, why I really hope that the information I amassed up is correct. But despite the danger of drifting into off-topic here: How many other bigger issues with Java version bumps are out there, still? The module aspect is what I could imagine, but were any other bigger changes introduced since the release of Java 9/10? I never thought about users playing Minecraft on rigs that support Java 8 to their max, however. I remember that Mojang did the Version bump to Java 8 with the knowledge that, iirc, less than 1% of the playerbase was still on Java 7. Assuming this is actually an issue: Would Mojang be willing to share such information with the dev team?

Wait! Before you post "stop using newer java", this thread isn't meant exactly for that - it's more that I'm curious, so this is more an essay than a complaint or anything. The last time I've been heading into the guts of Forge-modded Minecraft was before I started an apprenticeship, however I recently caught the news that Java 15 now saw the light of the day - and that there's a new garbace collector coming with it (sort-ish). The collector I'm talking about is the Z-Garbage Collector, but I won't go into details about it. If you're curious as well, go here (I think it's super intriguing!). And as all things go, curious me installed the latest openjdk version (can't be bothered to take the Sun JRE - yet), just to be greeted with what had been coming with Java 11 (?): Nashorn is no more! And, well, as was my Minecraft process. Forge's Coremod Engine appears to depend on it in some way. In particular, it appears that loading coremods is what causes the coupling, which is surprising for me. As far as I know, Nashorn is a Javascript Engine and I'd normally expect to see one of those in the vincinity of the Web APIs I build at my workplace, so why should it end up in Minecraft, out of all places? Well, I did some more research. I started out with looking for the CoreModEngine class on GitHub, only to find it not being located in Forge itself. Then were does it come from? Here! Core Mods, according to the project description, are supposed to only do replacements of certain hardocded things. Well, that's at least how much has settled in my mind from briefly skimming the introduction, but it also stated that coremod loading is based on Javascript because of exactly this reason: Keep the core-modding clean(er)(ish)(I think?). But what does this mean for Forge? Well, I think it is safe to say that Forge depends on the CoreMod part. This means that if Forge considerd to add support for newer Java versions, the CoreMod part would need to be updatet. Updating, however, doesn't necessarily mean that Nashorn must be replaced! OpenJDK has a repo up for Nashorn exclusively, you can check it out here. Whether or not that will be enough for the module stuff introduced in a version after 8 (lost interest in Java around that time) is something I cannot assess, however I think that we might be able to, well, actually do that. Possibly. If this cannot be done for some reason my lacking experience disallows me to comprehend, well, it'd mean that the respective could would need to be replaced, which seems like a PITA, just judging from what I have seen so far. But that sums it up for this post! Best Regards.

Heya sieben, thanks for the answer! No questions left on my end ?

So, it's a little hard to find any info about this, but how come modders do not need to specify IDs for their items and blocks anymore? I know, I know, it's been some years since Forge does that for one now (seemingly), but I just read through a thread from 2013 in which Lex said that it'd be not possible at that point in time, so how did that change and how does it work? Just really curious ?

My bad, corrected it. Well, I wanna update a simple value which is depending on the current weather/game time and block position.

Heya, im fairly new to modding mincraft and cannot bring google to give me results for my question. Let's assume I want to create a block which I want to update every tick whilst its chunk is loaded. Which approach would be best suited? Where can I read more about the Block Update and Chunk loading mecanics, for further reference? Thanks in advance!
