GroupsGroups

A Group treats several tweens as one step: it pauses, cancels, and completes them together. Sequences introduces groups.

var step = Group.Of(sprite.TweenPositionX(300, 0.6), label.TweenModulateAlpha(0, 0.6));
await step.End;

Create

Member	Type	Meaning
Group.Of(tweens)	Group	Group running handles, on any targets
node.Tween(first, second)	Group	Start several definitions on one node as a group; see starting playback

Control

Member	Type	Meaning
Pause()	void	Pause every member
Resume()	void	Resume every member
IsPaused	bool	True while every active member is paused
Cancel()	void	Cancel every member still playing

Status

Member	Type	Meaning
Members	IReadOnlyList<TweenInstance>	The grouped handles
IsTerminal	bool	True once the group has ended
CompletionReason	Reason?	Completed, or the reason of the first member that stopped early; null until the group ends
Error	Exception?	The exception that faulted a member, if one did

Awaiting

Member	Type	Meaning
End	Task<Reason>	Completes when every member has ended; faults when a member faults

Rules

• If one member stops early or faults, the group cancels the others and reports that member’s reason or exception.
• A group has no State or Progress; read its members for those.
• A group doesn’t link timing: each member keeps its own start and delay. A Chain plays definitions in order.
