Client Side Crystals
by cutebow
Client Side Crystals shows end crystals on screen the moment a player places them, so a click appears to register at once regardless of ping.
What it does
When a crystal is placed, the mod draws a client-side copy that looks like the real entity. Depending on the chosen setting, that copy is swapped for the server-confirmed crystal as soon as the server responds. Placement, breaking and crystal behavior on the server are not changed, and the visual is only local.
A tint option highlights the temporary client-side crystal so the player can see when the swap happens, which helps with timing in crystal PvP. The mod is aimed at players on high ping who want confirmation that a click placed a crystal. It runs on Fabric in the client-side only environment, so servers need nothing installed.
Files are published for Fabric for 26.3, with builds covering 1.21 – 26.3 across 17 release versions, released under All rights reserved; the source code is publicly available. The mod requires Fabric loader 0.19.3 or newer.
Key features
Instant placement visual
A crystal appears on screen as soon as it is placed, before the server confirms the placement.
Swap to the real crystal
The temporary client-side crystal is replaced by the server-side one once the server confirms it.
Tint highlight
An optional tint marks the client-side crystal so the moment of the swap is visible.
No packet changes
Crystal placement and breaking are handled as normal, and only the displayed visual is affected.
