Crystal per Second HUD
by HelixCraft
Crystal per Second HUD shows how many End Crystals a player destroys each second, drawn as a small overlay on the game screen.
What it does
Real-time tracking of End Crystal destructions feeds a per-second figure, shown as CPS (crystals per second), in the HUD. Two calculation modes are available: Instant Mode averages over the last 3 intervals and reacts quickly, while Smoothed Mode counts over a rolling 1-second window for a steadier figure. The value updates continuously, so no manual refresh is needed.
The HUD can be dragged to a new place and resized directly on the screen. A quick-access gear icon opens an editor popup with display options, including a toggle for a dark background box behind the text. Fabric API is required, and the mod runs on the client only, so servers do not need it. It is published for Fabric across 12 release versions, 1.21 – 1.21.11, and is released under CC0 1.0 Universal, which makes it open source.
