My issue with this is the same as the past PRs on the subject. There's no explanation or documentation of what the values mean, or why it's 0.05 by default. What's the unit? Blocks per seconds? Blocks per tick?

There's also going to be questions like why doesn't setMovementSpeed() affect flying speed, and why the server-side flight speed doesn't change when sprint-flying (which is inconsistent with movement speed).

The name setFlightSpeed() would be more in line with functions like setMovementSpeed().

I also think the name isn't quite right. It will indeed be confusing. However, I don't think that the unity problem should hinder the merge of adding APIs. It's up to the developers to find out what they're modifying, and a warning could be added in the docs about this. That the unit is not determined and that the value should be handled with care?

Looks ok to me

Apparently with tests I have done $value * 10 are the blocks per tick that the player will fly. So the default value 0.05 sets the player's flight speed to around 0.5 blocks per tick.

I've been testing if other attributes like movementSpeed or walkSpeed can modify the flight speed, but that doesn't happen. Alosi it seems that walkSpeed only modifies the player's fov.

When a player sprints while flying his speed is duplicated, with the default value the player's flight speed will be around 1 block per tick. The curious thing is that this only happens in client-side.

@Sergittos @ShockedPlot7560 I think this PR is fine once documentation on the value of the FlySpeed is present. As in, an explanation as to how the values are calculated.

if this correct can't we use blocks it can travel per tick as a parameter in the function instead of magic numbers

If @IvanCraft623 researchs is correct, we can document the method with this and it will be ready to merge for me.

Done.

Documentation is enough for me.
