Where it goes
Is Client Side Crystals required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does Client Side Crystals 1.21.X-26.X need?
1.21.X-26.X. Change the file and its required mods may change too.
Install YetAnotherConfigLib (YACL), Fabric API first. We found matching files for this game-version and loader setup. 2 come through another mod in the chain.
2 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Client Side Crystals add?
ClientSideCrystals
Recently entirely reworked, all older versions removed.
Makes end crystals appear instantly on your screen the moment you place them no matter your ping, giving better looking crystaling and better timing feedback in crystalpvp. no packets are changed crystaling is still handled like normal. read below for more about what the mod does
How it works in depth, Basiclly what it is doing is when you place a crystal it will put a fake client side crystal that looks real and depending on ur setting it will either seemlessly switch from the fake client side visual only crystal to the real one that was placed server side but the real crystal is fully unaffected. like placement and breaking is fully unaffected the goal of the mod is just supposed to give like the visuals of zero ping like no delay when placing but keep in mind its entirely visual hence the red like highlight in the gallery thats the tint setting which is to highlight the fake crystal to show like when it changes.
you might have worries about things like would it mess up timing, to answer this not really and if you are really picky the tint option could help with that since it would tell you right as when it switches to the real crystal but mainly the mod is just to help with like confidence that your click infact did work and did place the crystal. when alot of the time you could accidently second guess yourself. If you are a player who is on high ping then you def should use this mod! as it helps a ton mentally.
It’s only visual and doesn’t change how crystals behave on the server, so it’s not a cheat, it snaps back to the real crystal right as the server confirms the real one but it fills the gap of the crystal not existing so it looks instant.
