Match creative flying behavior to Java Edition

[MCbabel]

Description

Adjusts creative mode flying to feel more like Java Edition. Not sure if this is something everyone would want, but I wanted to share these changes and see what people think.

Tested with both keyboard & mouse and controller - controller flying still works as expected.

Changes

Previous Behavior

Creative flying used a console-specific movement overlay where sprint-flying was pitch-dependent (looking down made you fly down), vertical movement was asymmetric (descending much faster than ascending), and sprint didn't noticeably increase horizontal flying speed.

Root Cause

The 4J console port added a separate sprint-fly movement path on top of the base travel system. This overlay used the full 3D view vector for direction (including pitch), had its own quadratic speed ramp-up, and bypassed the standard flyingSpeed multiplier. Additionally, onGround was forced true while flying, which caused LivingEntity::travel() to use ground movement speed instead of flyingSpeed.

New Behavior

• Forward movement while flying is always horizontal regardless of where you look
• Sprint (Ctrl) doubles flying speed
• Ascend (Space) and descend (Shift) are the same speed
• Smooth vertical deceleration when releasing keys
• No jump impulse while flying (prevents unintended speed boosts)

Fix Implementation

LocalPlayer.cpp:

• Removed the 4J sprint-fly overlay (viewVector-based movement + Player::move call)
• Symmetric ascend/descend at 0.15 per tick
• Removed yd = 0 override that killed vertical momentum

Player.cpp:

• travel(): flyingSpeed uses sprint multiplier (2x), onGround temporarily set to false so LivingEntity::travel() applies air-friction physics
• jumpFromGround(): early return when flying to prevent jump impulse stacking
• Sprint speed bonus changed from 1.3x to 2x

• I think I've only seen a few requests for this feature on Discord, but not here on GitHub.

If the feature is something that not everyone wants, it could perhaps be added to the game sooner or later as a setting that can be activated.

I don’t personally think this is a good change. This isn’t a dedicated Windows fork of LCE, and even then the flying behavior in LCE is part of the distinct look and feel of the game. We should not gut it in favor of a less interesting flight system. It’s not like using the controller style flight with keyboard and mouse is a worse experience at all.

If we did accept this, it would be something behind an opt-in config setting. Improving the existing flight controls is fine, but eliminating the view directional flight kinda kills the fun IMO

+1 to the feedback here. Please do not integrate this as-is.

[MCbabel]

That's fair, I understand the concern about changing the core feel of LCE's flight. I'll update this to be an opt-in setting so it doesn't replace the default behavior. Working on it.

LCE's flight behavior just feels odd and sometimes hard to control on Mouse and Keyboard, I'm for this change although yes it should be a toggle-able option.

i will rather keep the consle flying, or at least add this as a option.

Console flying feels amazing, though a seperate option would be neat

sorry for the messy force pushes, github sometimes confuses me a little
i hope everything is correct now
