Flaps

Welcome to the Flaps wiki! Flaps is a library that allows you to communicate with Minecraft resource pack shaders (different to shader packs) from the server, allowing you to create dynamic visual effects on players screens without mods, just by providing the resource pack for players.

Here's a few examples of the effects that can be achieved, but the possibilities are essentially endless:

Screen shakes

Useful for horror scenes, boss fights, etc

Seasonal/biome effects & colour grading

Desert haze and heat distortion, winter fog and snow, etc

winter.mp4

desert.mp4

Roll effect when using Elytra

A recreation, without mods, of the legacy console edition effect where you'd tilt slightly when turning with an Elytra.
