What It Does
Client Side Crystals solves a specific annoyance in crystal PvP: the delay between placing an end crystal and seeing it appear on your screen. If you have high ping, that gap can make you second-guess whether your click actually registered. This mod closes that gap visually. When you place a crystal, it spawns a fake, client-side crystal immediately. This fake crystal looks real and stays on your screen until the server confirms the actual placement. At that moment, the visual snaps to the real server-side crystal.
The mod is strictly visual. It doesn't change how crystals behave on the server. Placement, breaking, and interaction logic remain exactly as they are without the mod. No packets are altered. The fake crystal is purely a visual placeholder that fills the time gap caused by network latency.
How It Works
The mod creates a temporary visual entity when you place a crystal. This entity is marked as "pass" in the code, meaning all hits and interactions pass through it. So it does not block your sword or affect combat mechanics. That exists only to give you immediate visual confirmation that your input was processed.
You can enable a tint setting that highlights the fake crystal. This helps you distinguish the temporary visual from the confirmed server-side crystal. If you're picky about timing, this tint tells you exactly when the switch happens. Here's the thing, for most players, the mod simply provides confidence that your click worked, removing the mental friction of waiting for the server response.
Compatibility and Requirements
This mod is client-side only. It isn't supported on the server side. You must have it installed on your client to see the effect. But it requires the Fabric loader. That doesn't work with Forge or NeoForge.
The mod supports specific Minecraft versions. This supported list includes 1.21, 1.21.1, 1.21.2, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1, 26.1.1, 26.1.2, 26.2, and 26.3. It doesn't support versions outside this list. Don't assume it works on 1.20 or older releases.
The mod requires two other mods to function: Silicon and YACL. You must install these alongside Client Side Crystals. The project is licensed under All Rights Reserved, meaning you can't redistribute or modify the code without permission from the author, cutebow.
Who It's For
This mod is for players who compete in crystal PvP on servers with high latency. If you play on servers like VTL, mcpvp.club, or pvptiers.com, you likely know the frustration of delayed crystal visuals. The mod is allowed on these servers. It's not a cheat. It does not give you an advantage in terms of speed or power. That only improves your visual feedback. If you play on low ping, you might not notice a difference. If you play on high ping, it helps a lot mentally by confirming your actions instantly.
