Implement Customisable Gravity

[PiggyPiglet]

Description

An API to interact with and modify gravity would be extremely useful.

Things To Avoid:

• Velocities applied on the player, these will lag the client with high latency, at least they do with spigot. They also don't allow for strafing afaik, but perhaps my implementation was just shite.
• Potion effects are not a solution, like ever.

Possible Solutions:

• Mount the user to an entity and perform the velocity application on that. Dunno if it'll lag or not, don't think it will, probably worth a try. Not sure if the client sends movement packets on all entities, so you may need to use a specific entity like a boat. Problem is this'll look fucked on the client, and it'll take effort to make it look right for other players.
• Get mojang to implement gravity on the server side

Thanks for the issue!

As I said to you on Discord, I can very likely implement this for anything the server controls (a.k.a entities), though I am not sure about how to go about this for players, as the client is the one that notifies Krypton that it is moving, and so I would likely have to tell the client to jump back, which would not be smooth at all (of course).

Nevertheless, I will see what I can do about the players, and I'll definitely consider it for entities.
