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.
