About this Mod

Hero's Anchor Optimizer

What does it do?

  • Optimization that fixes waiting on the server after anchor explosion before anchor block is removed. Replaces it with a visibly different 'fake' anchor (that can be replaced like a fern) to not change functionality of airplacing. This allows you to not have to wait for the server to be able to place another block in the same place.

Is this allowed?

** Allowed on many major servers such as:**

  • Vanilla+

  • PVP Legacy

  • USPVP

  • MCPVP

  • DonutSMP

  • LeoneMC

  • Vanilla (Crystal PVP) Tier list

    but please ask before using on any servers that aren't on this list or haven't explicitly allowed it.

How to use?

  • Plop into your .minecraft/mods folder
  • Make sure to have fabric api (for versions <1.21.11)

I want to change the fake anchor texture

  • You can do this with a pack. You can either change the model in

assets\herosanchoroptimizer\models\block\fake_anchor.json

or change individual textures in

assets\herosanchoroptimizer\models\block\fake_anchor_side.png and/or
assets\herosanchoroptimizer\models\block\fake_anchor_vertical.png

Compatibility

  • Should work with any mods that don't edit an anchor's functionality.

Frequently Asked Questions

Does Hero's Anchor Optimizer need to be installed on the Minecraft server?

No. Modrinth marks Hero's Anchor Optimizer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Hero's Anchor Optimizer require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10, 1.21.9. Files for different loaders are not interchangeable.

Hero's Anchor Optimizer is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
