Commands:Tween commands

Tween commands specify how an Actor changes, or "tweens", from its starting state to a new state.

A tween command must be specified in order for an object to change states.

Shared commands

These commands are available in all StepMania versions since StepMania 3.9.

Command	Arguments	Example	Effect
`sleep`	Float	`sleep,3`	Waits x amount of seconds, then changes state immediately.
`hiberate`	Float	`hiberate,3`	Tells all children to pause tweening for x amount of seconds, then resume tweening.
`linear`	Float	`linear,0.75`	Changes from one state to another at an even pace.
`accelerate`	Float	`accelerate,1.5`	Starts tweening slowly and speeds up over time.
`decelerate`	Float	`decelerate,0.9`	Starts tweening quickly and slows down over time.
`bouncebegin`	Float	`bouncebegin,2`	Will apply a "bouncing" effect to the beginning of a set motion followed by a time amount.
`bounceend`	Float	`bounceend,1`	Will apply a "bouncing" effect to the end of a set motion followed by a time amount.
`spring`	Float	`spring,5`	Tweens past the destination state, tweens backward, then tweens forward to the final state.

These commands allow you to change how the tweening itself is done.

Command	Arguments	Example	Effect
`hurrytweening`	Float	`hurrytweening,0.25`	Multiplies tween time by the amount given (the example would speed up tweening 4x)
`stoptweening`		`stoptweening`	Stops tweening at the current state instead of finishing.
`finishtweening`		`finishtweening`	Stops tweening and goes directly to the final state.

These commands are only available in StepMania 4.0 builds.

Command	Arguments	Example	Effect
`smooth`	Float	`smooth,1`	Tweens in a bezier curve that creates a movement that "smooths" itself out.
`compound`	(Tween, Float) (multiple)	`compound,8,linear,0.25,smooth,0.75`	Combines several tweens together, given a tween type and percentage (example would tween linearly for 2 seconds, then accelerate for 6 seconds).
