Minecraft’s Most Advanced TNT Weapon is Here

Storyline & Background

The video showcases the latest version (6.0) of the Orbital Strike Cannon, an advanced TNT weapon designed for Minecraft Java Edition 1.21+. The previous version (5.0) broke due to changes in Minecraft 1.24 affecting entity interactions with honey blocks, which required a complete redesign. The creator spent two months fine-tuning the new design to maximize its functionality and features.

Key Gameplay Highlights & Features

  • Compatibility: Works only on Minecraft Java Edition (not Bedrock or Pocket Editions). It relies on vanilla mechanics and breaks on modified servers like Paper or forks due to entity movement changes.

  • Performance: Firing the cannon causes significant lag because Minecraft’s collision checks (AABB collision detection) scale cubically with motion, resulting in massive computation times.

  • Optimizations Needed: Mods such as Fabric with Carpet and optimization mods like Lithium and Optimized Fast Entity Movement are recommended to reduce lag and make the cannon usable.

  • Schematic Use: The cannon is built using schematic files with Lightmatica, allowing easy pasting and updates without block-by-block tutorials.

  • Multiplayer Limitations: Complex redstone contraptions break when pasted on vanilla multiplayer servers due to fill command mechanics. Mods like SerUX are needed for multiplayer schematic pasting.

  • Placement Considerations:

    • The cannon fires omnidirectionally, so no rotation is needed.
    • Location affects stealth versus speed: closer cannons charge faster but are easier to find; distant cannons are stealthier but take hours to charge.
    • Ideal build locations include dense forests or mangrove swamps for concealment. Underwater and ocean builds are not possible due to daylight sensor limitations.
    • Trapdoors automatically open and close to conceal the cannon when players approach or leave.
    • The cannon is internally water-flooded to prevent premature explosions.

Building & Setup Tips

  • Use Lightmatica’s schematic editor for efficient building and block replacement.
  • Ensure schematic placement is chunk-aligned (coordinates divisible by 16) for proper function.
  • Use chunk loaders in both the Overworld and Nether to keep the cannon active remotely.
  • Nether chunk loaders can be hidden by placing portals strategically to avoid detection.
  • Material list and entity placement are managed via Lightmatica; required items include boats, chest minecarts, hopper minecarts, iron blocks, moss blocks, and music discs.
  • Hopper minecarts require precise placement using rails and powered rails.

Control & Communication System

The new cannon employs binary encoded counters, which are simpler but less dense than previous decimal counters, for firing instructions.

  • Firing instructions consist of 55-bit sequences transmitted wirelessly using serial binary encoding spread over time.
  • Wireless receivers are designed to avoid random activation upon chunk loading by using passcodes.
  • A control terminal allows remote input of:
    • Target coordinates
    • Payload type (nuke or stab charge)
    • Payload size/depth
    • Passcodes
  • The magazine holds up to 8 payloads for different targets, which can be fired manually or automatically.
  • A fishing rod can be used as a portable wireless trigger to fire the cannon remotely.
  • Multiple cannons can operate on isolated wireless Redstone networks to avoid signal jamming.

Payload & Warhead Design

  • Two main payload types: Nuke and Stab Charge.
  • The stab charge uses a three-stage acceleration to reduce TNT “swing” (inefficient oscillation), achieving up to 99% blast efficiency.
  • The nuke uses TNT prime momentum mechanics to form rings of TNT that expand, creating a large blast radius.
  • The new nuke design improves efficiency by scaling TNT amount with ring radius, reducing lag and build time by half compared to previous designs.
  • Payload height is adjustable for optimal explosion effect (airburst or ground penetration).
  • Perimeter mining with the cannon is possible by exploding TNT midair and lowering subsequent shots gradually, demonstrated on the WaveTech SMP server.

Strategies & Key Tips

  • Always test the cannon in a creative single-player world first to fine-tune parameters.
  • Use schematic subregions to selectively build or modify parts like trapdoors.
  • Choose build location balancing stealth and firing speed based on server population and terrain.
  • Use chunk loaders to keep the cannon and control terminal active remotely.
  • Regularly check and restart chunk loaders after server restarts to maintain functionality.
  • Use the provided Excel spreadsheet for configuring targets, passcodes, and estimating charge times.
  • Avoid overloading the cannon with excessively large nukes to prevent server lag.
  • Conceal trapdoors and daylight sensors with natural terrain and vegetation.
  • Use wireless Redstone network isolation to prevent communication jamming on multiplayer servers.

Additional Notes

  • The creator apologizes for previous incomplete tutorials and hopes this comprehensive video clarifies the design.
  • Encourages upvoting a bug report on Minecraft’s entity collision inefficiency to improve vanilla performance.
  • Mentions WaveTech SMP and JKM’s New WaveTech recap series for related content on perimeter cannons and other projects.
