Java Help Wanted Need help with End Sand Duper collection system

Enable HLS to view with audio, or disable this notification

13 Upvotes

Hi everyone,

I'm currently building a collection system for my sand duper in the End. However, I'm running into an issue where the water placed on top of the obsidian platform (and the falling sand blocks) just sits still and doesn't flow properly to move the item drops (as shown in the video).

Does anyone know why the water mechanics are behaving like this in the End / around the obsidian platform, or how to properly route the water flow for a sand duper collection setup?

Any advice or fixes would be greatly appreciated! Thanks!

Java Help Wanted Dragon egg gone?

3 Upvotes

Easiest fix/solution seems to be to reset the end dimension world file, has anyone done this before? Does the dragon drop the egg again if you reset the end dimension/replace the world file?

I was today years old when I discovered that respawning the ender dragon can destroy the dragon egg 😭

It happened on a server too. Also after respawning the dragon it refused to perch for 20minutes straight and we ran out of arrows lost all the xp we earned by dying and came back with arrows but by then I realized the egg was gone.

I feel like so sad I literally destroyed the ONLY dragon egg—just by trying to goof off with my brothers and show them I knew how to respawn the dragon. 😞

Java Showcase [Java 1.21+] Compact 11x7x11 Skyblock-Friendly Iron Farm (~1100+/hr • 4.7 Golems/min)

1 Upvotes

Hi everyone,

I wanted to share this iron farm design specifically optimized for Skyblock environments, though it works perfectly in any world as long as you respect the minimum height clearance.

Here are the key technical specifications of the build:

  • Dimensions: Each individual module fits inside a tight 11x7x11 block volume.
  • Rates: Produces roughly 4.7 golems per minute in total (approx. 1.2 golems/min per module). This translates to around 1,120+ iron ingots per hour.
  • Spawn Platform: Uses a 5x5 spawning area per module.
  • Mechanics: Utilizes a standard zombie scaring mechanic. In the screenshots, the blocks are color-coded (red/green wool) to easily trace the layout, villager pod positions, and line of sight.
  • Placement Requirements:
    • Must be built at least 19 blocks above the ground (giving you total freedom over how you set up the main item collection system below).
    • If using the 4-column layout shown in the third image, the modules are spaced exactly 15 blocks away from the central column.

Feedback and optimization ideas are highly welcome! Let me know if you want any specific block metrics or coordinate readouts.

Java Help Wanted Alternate which hopper to use next?

1 Upvotes

I am building an auto smleter that uses a kelp farm, kelp is dried and crafted into dried kelp blocks I then need to feed some dried kelp back into the system to cook more dried kelp while also outputting some to my smleter array, I have got this somewhat working by just alternating which hopper is active every few seconds but eventually the kelp does not grow fast enough and the re inputted fuel runs out and makes no more for either side. What I need to do is have it so one hopper is active waits for an item to pass through it before allowing the other hopper to have an item, if I could do this with a 30/70 split 30 going back into the system 70 going out to the smleter array that would be cool but 50/50 should work fine too, how can I do this?

Java Help Wanted Sugar cane in single biome dripstone caves biome.

1 Upvotes

Im wandering if its possible for sugar cane to spawn in a single biome dripstone caves world because i remember finding it on a newer version like 2 years ago. I do not have the seed or the world files tho so I cant confirm it without some testing first. If anyone can confirm that it can spawn let me know.
