Minecraft has a vanilla glitch where moving your head in a specific up-down pattern can allow you to fly infinitely
This mod simulates those patterns automatically.

Note: Video is not made by me

Features:

1. Customizable keybind to activate flight
2. Configurable automatic flight settings.
3. Configurable (and toggleable) HUD display which shows elytra information including
   • Flight Mode (Automatic | Manual)
   • Altitude
   • Flight Speed
   • Elytra Durability
   • Autopilot destination coords and distance
4. Automatic Collision Detection Utility
5. Autopilot
6. Automatic music player (plays a series of tracks during auto-piloted flights, tracks are created by Swaritz)

How to use Automatic Mode?

Step 1: You will need to be flying in the air using an Elytra.
Step 2: Gain a bit of height; 100 blocks above ground level is recommended.
Step 3: Press the keybind (default 'right alt') to toggle Automatic Flight on.
Step 4: Enjoy!

Collision Detection Utility

The Collision Detection Utility will automatically activate when in Automatic flight mode. If an obstacle appears in front of the player, the Utility will:

• Deactivate automatic flight
• Turn the player 180° in order to avoid the obstacle
• Print a warning in chat
  

How to use Autopilot?

Step 1: You will need to be flying in the air with Automatic Flight Mode enabled (see above).
Step 2: Enter the command /setDestination where x z are your destination coordinates.
Step 3: Enjoy!
Step 4: The mod will automatically land if 'Perform Automatic Landing' is enabled in the Config.
Step 5: To unset your current destination, use /removeDestination. To reuse your previously set destination, enter /setDestination without any further coordinates.

Flight Analytics

Each autopiloted (where destination is set with /setDestination) flight's stats are recorded and stored on a per-flight basis. When a new autopiloted flight starts, the old data will be cleared.
The analytics includes the following data:

• Distance
• Time
• Average speed
• Elytra durability used

You can see the stats by using the command /flightanalytics.
Alternatively, you can enable "Automatically print analytics" in the config.
If you do not wish for the analytics data to be recorded, you can disable it entirely in the config.

Explore Area

This feature explores and generates all chunks within the boundries of the rectangle set by the coordinates x1, z1, x2, z2
where x1 and z1 are the bottom-left coords of the rectangular area you want to explore
and x2 and z2 are the top-right coords of the rectangular area you want to explore.
To use, run the command /exploreArea

Config

You can access the Config in the ModMenu Config Screen. Detailed instructions are given in the sidebar for each option.
