Movement

control is game.control() — three direct writes onto the local player. gameSettings is game.settings() and reads or writes a slice of the vanilla options.

on<ClientTickEvent> {
    control.sprinting(true)
}

on<MoveInputEvent> {
    it.forward(true)   // hold forward for this tick
    it.jump(false)
}

#Direct commands

Every method throws ScriptThreadException off the client thread and ScriptStateException with no world loaded.

#Rewriting input

The tick's seven raw movement flags are MoveInputEvent; the game rebuilds the player's input from them after the handler returns. The frame's mouse deltas are LookInputEvent.

What is physically held right now, independent of the tick's input, is Keys and binds; aiming the head at a point is Rotations.

#Game settings

Neither setting is restored when the script switches off; scaleFactor() is the number 2D render pixels are divided by to get vanilla interface coordinates. PerspectiveEvent fires on every point-of-view change, whoever caused it — Event list.

#Perspective

#Perspective constants

#Slowdown

The movement multiplier the game applies while an item is in use is SlowdownEvent; the value written back replaces the vanilla one and is not clamped.
