ElytraWarn

ElytraWarn watches your elytra only when it matters: while you're actually gliding. The instant your equipped elytra's remaining durability falls below 10%, a red [!] ELYTRA LOW x% banner blinks in the upper-center of your screen and a short alert sound plays — repeating every few seconds while you stay in the danger zone — so you can land or swap before your wings break in the air.

What it does

• Only warns while gliding. No nagging on the ground, no banner when the elytra is fine — the alert appears exactly when a break would actually drop you out of the sky.
• Blinking banner + sound. The flashing red text is hard to miss in your peripheral vision, and the audio cue catches you even if your eyes are on the horizon.
• Live percentage. The banner shows the remaining durability so you know how much margin you have left.
• Auto-resets. Repair or swap to a fresh elytra and the warning clears itself.

Why it's different

The vanilla durability bar is a tiny sliver at the bottom of the hotbar — useless when you're cruising at altitude. ElytraWarn ties the alert to the gliding state, so it speaks up precisely when a break means a long fall.

How it works

• Reads getDamage() / getMaxDamage() on your chest-slot elytra and checks isGliding() every client tick — no mixins, no packets, no server component.
• Drawn via Fabric's HudRenderCallback, so it respects F1 (hide HUD) and pauses/screens automatically.

Controls

• Y — toggle the warning on / off (default: on).
