MoveNetwork natives in RedM are typically used to control specific scenarios that have multiple animation steps and involve interacting with items/objects in the world.
For example, MoveNetwork natives are used to control (portions of) the bathing sequence, campfire interaction, base game character creation char movement, and many of the minigame sequences found in the game.
They are also used in the safe-cracking minigame - this is the example we will be using in this documentation, as it relates to the vault itself.
