[Feature] Setting player angle automatically for max elytra distance.

With the right angles, you can fly infinitely (or untill your elytra breaks) and even gain height with just 40 blocks of height. (https://www.youtube.com/watch?v=F69K1-cMaf8)

Would love to see this becoming a feature.

i think some hack clients alr have this

Not sure how that's relevant to this issue

Inspired by that YouTube video, I wrote this JsMacros script in JavaScript:

Autopilot

const AUTOPILOT_TOGGLE_KEY = "autopilot";
const DESCEND_PITCH_LIMIT = 38;
const ASCEND_PITCH_LIMIT = -47;
const SPEED_THRESHOLD = 42;
const DESCEND_PITCH_INCREMENT = 0.5;
const ASCEND_PITCH_INCREMENT = 5;

let isAutopilotEnabled = !GlobalVars.getBoolean(AUTOPILOT_TOGGLE_KEY);
GlobalVars.putBoolean(AUTOPILOT_TOGGLE_KEY, isAutopilotEnabled);

if (isAutopilotEnabled) {
    const player = Player.getPlayer();
    const playerYaw = player.getYaw();
    let descending = true;
    let currentPitch;

    if (player.isFallFlying()) {
        player.lookAt(playerYaw, DESCEND_PITCH_LIMIT);
    }

    while (player.isFallFlying()) {
        currentPitch = player.getPitch();

        if (descending) {
            player.lookAt(playerYaw, Math.min(currentPitch + DESCEND_PITCH_INCREMENT, DESCEND_PITCH_LIMIT));
            if (player.getSpeed() >= SPEED_THRESHOLD) {
                descending = false;
            }
        } else {
            player.lookAt(playerYaw, Math.max(currentPitch - ASCEND_PITCH_INCREMENT, ASCEND_PITCH_LIMIT));
            if (player.getPitch() <= ASCEND_PITCH_LIMIT) {
                descending = true;
            }
        }

        Client.waitTick();
        if (!GlobalVars.getBoolean(AUTOPILOT_TOGGLE_KEY)) {
            break;
        }
    }
}

GlobalVars.putBoolean(AUTOPILOT_TOGGLE_KEY, false);

Notes:

• To use that script, while flying, press the keybind for the script. I don't know how to write that in Java.
• I tried to fine tune the variables for maximum height gain on each cycle. Another approach might be maximum speed while ensuring not to lose height.
• To gain the max height, it requires an initial height of about 62 blocks. For a lower initial height, it can start with different values (like lower DESCEND_PITCH_LIMIT and SPEED_THRESHOLD) and slowly change to those values when it gains enough height.
• One way I can think of to use it in clientcommands is to have a /cautopilot [on|off] or a config. If it is toggled and the player has enough height from the ground, the autopilot will trigger.
