About this Mod

Anchor Optimizer!

This mod removes the anchor client-side instantly when interacted along with removing any nearby glowstone, ensuring you don't accidently interact with glowstone blocks which shouldn't actually be there anymore.


Information

When interacting with a charged respawn anchor, you have to wait for a server response before it actually gets removed from the client world along with the blocks in it's radius. This would prevent players from moving past the block or get caught on glowstone (from a safe anchor for example). This mod fully removes the respawn anchor when interacted with, and if there's any glowstone nearby which should be removed then it proceeds to do so.

This mod does not remove the ability to air place. While it does remove the respawn anchor completely, it stores the interacted position until the server eventually does respond, ensuring the player can still air place.

Client-sided explosion

This feature is disabled by default and must be enabled manually via the config menu. This feature creates an explosion client-side, allowing the player to fall into holes much faster. Unfortunately this feature is unlikely to be allowed on servers and could also flag anti cheats... Use with caution.

Frequently Asked Questions

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

No. Modrinth marks 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 Anchor Optimizer require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.8, 1.21.4. Files for different loaders are not interchangeable.

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.
