Rearview Mirror Mod

A client-only Fabric mod that adds a rearview mirror.

The mirror allows players to see behind them within a configurable HUD box at all times. No more F5 spamming, no more creepers sneaking up!

Controls

Default keys:

• `R` - toggle mirror HUD
• `O` - open the config screen

Inside the config screen:

• Use the Mirror FOV slider to change the rear camera angle
• Drag and resize the mirror as needed
• Edit the framerate of the mirror for performance.

The config is saved to:

.minecraft/config/rearviewmirror.json  

Performance

Because this mod works by calling an extra render before the main render for every frame,
it adds a constant multiplier on the complexity. I've tried lowering the resolution and animations
for the rendered image, however it appears to be capped by the overhead of rendering a frame.
As such the only meaningful performance improvement is by adjusting the framerate of the mirror, which
you can do in the in-game config screen.
