Motionomicon

This is a data pack that allows you to apply motion to a Player.
The name is a combination of the words motion and Necronomicon as it uses enchantments to apply motion.

How to Use

There are two types of functions: one that allows you to set the motion with the specified value and one that allows you to add motion on top of the existing motion.
Any of the numbers specified can range from -9.9999 to 9.9999.
Digits outside of that range won't be considered, meaning that 14.5 is the same as 4.5 and -23.8 is the same as -3.8.
These functions fail when the Player is in Spectator mode as motion cannot be applied when they are in said game mode.
The effects stack, which means you can call the functions multiple times and it will act appropriately.
For example, the following two calls result in a total motion of [1, 1, 0]:

function motion:set {x: 1, y: 0, z: 0}
function motion:add {x: 0, y: 1, z: 0}

This also means that the effects are applied immediately.
Note that due to floating-point precision errors there might an ever so slight error with the actual motion, though this tends to be negligible.
Additionally, the screen might flicker sometimes due to the rotate command having already rotated the Player.
Please be wary of this.

motion:set and motion:add

Both of these functions take the parameters x, y, and z, which are all numbers.
motion:set overwrites the current motion entirely.
motion:add adds the motion on top of the current motion.

Examples

Jump a single block upwards.

function motion:set {x: 0, y: 0.42, z: 0}

Dash in the negative z direction.

function motion:set {x: 0, y: 0, z: -2}

motion:set_rotated and motion:add_rotated

Both of these functions take the parameters left, up, and forwards, which are all numbers.
These functions use the Player's rotation as their axes instead of using the cardinal directions.
motion:set_forwards overwrites the current motion entirely.
motion:add_forwards adds the motion on top of the current motion.

Examples

Strafe left roughly 10 blocks.

function motion:set_rotated {left: 0.91, up: 0, forwards: 0}

Jump and move forwards one block.

function motion:set_rotated {left: 0, up: 0.42, forwards: 0.27}
