Advanced Autopilot

Advanced, automatic elytra flight.

This mod provides an advanced autopilot system for elytra flight. The autopilot knows how to ascend, glide, and land; it can also travel towards a goal, swap out elytra with low durability, and show flight information in a HUD. The mod is highly configurable, but has sensible defaults for getting started. If you want a simpler autopilot, I recommend TheMegax's Elytra Autopilot mod, which was the inspiration for this mod.

Features

A few of the mod's (configurable) features:

Elytra swap: Swap out elytra when durability is low
Emergency landing: Perform emergency landing when elytra durability is low
Flight resumption: Try to resume flight towards goal after error [experimental]
Goals: Fly towards a goal that is set by the player
HUD: Show flight information in a HUD (heads-up display)
Powered flight: Use rockets while gliding to increase speed
Risky landing: Dive straight down, then correct at the last moment
Rocket refill: Refill rockets from inventory into main hand
Unloaded chunk handling: Fly through unloaded chunks (for a limited time) before landing

Usage

To engage or disengage the autopilot, press the toggle key (default R) while flying
- If a goal is set, the autopilot will fly towards the goal
- Otherwise, the autopilot will maintain its current direction (yaw) indefinitely
- The autopilot's behaviour can be tweaked by adjusting the configuration
To trigger an automatic landing, use the /land command while flying
The autopilot is intelligent and will adapt its behaviour during flight
- However, it does not monitor the blocks around you; see limitations

Goals

To set a goal, use the /setgoal X Z command while flying (with or without the autopilot engaged)
To clear the current goal, use the /cleargoal command, stop flying, or disengage the autopilot

Behaviour

The pseudocode below describes the rough behaviour of the autopilot:

if a goal is set and we are close to the goal:
    land
else if we are flying through an unloaded chunk:
    land
else if we are high enough to start gliding:
    glide
else if we are holding fireworks:
    ascend
else:
    land

Configuration

The mod features extensive configuration for (almost) anything that you'd want to change
To access the configuration page, open the ModMenu
- Alternatively, you can manually edit the advancedautopilot/config.json file in your mod config directory
In the configuration, height refers to the vertical distance from the player to the ground, not the Y coordinate

Limitations

The autopilot does not monitor your surroundings (except your height)
- When ascending, it will happily crash you into a ceiling
- When gliding, it will happily crash you into a wall
- When landing, it will happily drop you into lava
- Due to this limitation, for the safest long-distance flight, I recommend flying above the nether roof
