`FreeCamera` in `FreeCameraPlugin` expected to move in relative Y axis

[kukumberman]

Bevy version and features

0.18.1

Expected behaviour

Camera should move in relative Y axis (coming from Unity Engine)

Actual behaviour

Camera moves in global Y axis, not sure it is by design or not

personal opinion / observation.

Free Cam Controller Example behaves exactly like Blender's Walk/Fly mode, which E/Q means goes up and down in World space.

I don't think this is a bug at all but an intended behaviour. Speaking for myself it'd be weird if E/Q goes up and down in local space.

Blender does have R/F as local space Move up and down, maybe this can be feature request if u want a local space translation too?

In Unity and Godot Q/E movement is relative to camera. Currently in bevy if you look down towards XZ ground plane you will lose an opportunity to move along Z axis (or X axis, depends on the yaw angle)

sure, sounds like a preference thing and key-binds could change that, I am on the camp of keeping it consistent with blender tho.

at the end of the day you just want a the ability to have local space up down movement right? that sounds simple enough to do. But I'd say this behaviour isn't a bug, that's all.
