Type Alias EaseFn

TEA-compatible tween primitive.

A Tween tracks animation progress (0→1) over a given duration. Drive it by dispatching a Tick({ deltaTime }) message on each animation frame and calling tweenStep in the update function.

Wire the tick via foldkit's Subscription.animationFrameEntry:

Subscription.animationFrameEntry({
  isActive: (model) => !allTweensDone(model.tweens),
  toMessage: (dt) => Ticked({ dt }),
})
