⚓ OptiPlus-Anchor

Zero-wait respawn anchor placement for Minecraft 1.21.11

---

🔎 What does it do?

OptiPlus-Anchor removes the wait between triggering a charged respawn anchor and the block clearing from the world. The anchor is set to air on the client immediately on interaction, so the slot is ready for the next placement without any server-confirmation lag.

The server-side detonation still happens normally, this just stops the empty-frame stutter that usually blocks re-placement at the same spot. The result: a smoother, more responsive placement loop during anchor PvP.

✅ Is this allowed?

No servers have been explicitly confirmed yet.

Please check with server staff before using this on any server, rules around anchor optimizations vary a lot, and what's allowed on one server may be bannable on another.

⚠️ Use at your own risk until a server has clearly approved it.

🎨 Can I change the anchor texture?

Not in this version. Unlike some other anchor optimizers, OptiPlus-Anchor doesn't swap in a "fake" anchor block, the real anchor is simply cleared from the client view immediately.

Because there's no custom block or model being rendered, there's nothing for a resource pack to retexture here. The vanilla anchor textures still apply right up until the moment the block is cleared.

🔧 Compatibility

Should work fine alongside any mods that don't alter respawn anchor behavior directly.

Mods that may conflict:

• Mods that change how anchors detonate
• Mods that change how anchors are placed
• Mods that add their own client-side anchor handling

If you run into weirdness, try isolating the issue by disabling other anchor-related mods first.

🛡️ Server-side opt-out

Per Modrinth rule 3.2, server admins can disable OptiPlus-Anchor for connected players. The mod listens for an empty plugin-channel message on optiplus:disable (kills both OptiPlus variants) or optiplus-anchor:disable (this variant only). The flag clears on disconnect, so the server must re-send the signal on each join.

Paper / Spigot / Bukkit:

server.getMessenger().registerOutgoingPluginChannel(plugin, "optiplus-anchor:disable");
// on PlayerJoinEvent:
event.getPlayer().sendPluginMessage(plugin, "optiplus-anchor:disable", new byte[0]);

Fabric server mod: send a CustomPayloadS2CPacket whose payload id is optiplus-anchor:disable (any body works) to the joining player.

Velocity / BungeeCord: forward a plugin message on optiplus-anchor:disable to the backend, or send it from the proxy.
