Currently i have my own custom demension and everything works fine(portal, etc..). I wan't to make custom world generation not like surface, etc.. So i need explain how that works?

        byte var4 = 4;

      RAPID DIGITAL RECOVERY IS THE FUTURE OF BITCOIN RECOVERY AND SECURITY

      By jaysonwilfred12 · Posted

      Reach Out To Rapid Digital: What sapp Info: +1 41 4 80 7 14 85 Email INFO: rap iddi gita lrecov ery @ exe cs. com Hello, my name is Jayson, and I’m 35 years old from the United Kingdom. My family and I recently endured an incredibly challenging experience that I wouldn’t wish on anyone. We became victims of a cryptocurrency investment fraud scheme that saw us lose a staggering $807,000 in USDT and Bitcoins. The fraudsters had created a convincing facade, and we were lured into investing, only to discover later that the platform was a complete scam. We were left devastated, not just financially, but emotionally, as we had trusted these people and believed in the legitimacy of the investment. After the initial shock wore off, we desperately searched for ways to recover the lost funds. It seemed like an impossible task, and we felt as though there was no hope. That’s when, by sheer luck, we stumbled across a post about Rapid Digital Recovery, a cryptocurrency and funds recovery organization with a proven track record in cybersecurity and fraud recovery. We decided to reach out to them, and from the first interaction, we were impressed with their professionalism and transparency. They explained the recovery process in detail and reassured us that they had the skills and expertise to track down the perpetrators and recover our funds. This gave us a renewed sense of hope, something we hadn’t felt in months. What truly stood out during our experience with Rapid Digital Recovery was their dedication to the recovery process. The team went above and beyond, using sophisticated tracking tools and cyber forensics to gather critical information. Within a matter of weeks, they had successfully located the funds and traced the scam back to the fraudsters responsible. They worked with the authorities to ensure the criminals were held accountable for their actions. To our relief, the team at Rapid Digital Recovery was able to recover every single penny we had lost. The funds were returned in full, and the sense of closure we felt was invaluable. We couldn’t have imagined such a positive outcome in the early stages of our recovery journey, and we are deeply grateful for the work they did. If you ever find yourself in a similar situation, I highly recommend contacting Rapid Digital Recovery. Their expertise, transparency, and dedication to their clients make them the go-to choice for anyone seeking to recover lost cryptocurrency or funds. They truly gave us back our financial future.

      [1.21.4] Could not resolve LocalPlayer.sendSystemMessage

      By Cherry05 · Posted

      This is my first time modding anything, so maybe just skill issue. I'm using Forge 54.0.12 and Temurin 21.0.5+11-LTS I wanted to create a custom keybind and to check whether it works I'd like to send a chat message. I tried using Minecraft.getInstance().player.sendSystemMessage(Component.literal("test")); but IntelliJ couldnt resolve sendSystemMessage(...). Since I saw people using it in earlier versions, I tried the same thing with 1.20.6(- 50.1.0), where it works fine, now I can't figure out if this is intentional and whether there are other options for sending chat messages. On that note, is there more documentation than https://docs.minecraftforge.net/en/1.21.x/? It seems very incomplete compared to something like the Oracle Java docs
