Simple scene library for Ebitengine.

This library provides the ability to run multiple ebiten.Game s in sequence, with each ebiten.Game as a single scene.

Sequence structure runs multiple ebiten.Game s in sequence. You can switch ebiten.Game s with Sequence.Switch or Sequence.SwitchWithTransition. Transition is used to draw (e.g. fade in and out) when switching between ebiten.Game.

Sequence also implements ebiten.Game.

If ebiten.Game implements some or all of the OnStarter, OnArrivaler, OnDeparturer and OnEnder interfaces, they are called at the following times:

OnStarter.OnStart is called immediately after ebiten.Game is switched.

It is called just before the first ebiten.Game.Update after the game starts.

OnArrivaler.OnArrival is called when the switched ebiten.Game starts and the Transition process is complete. For example, when the fade-in is complete. This function is useful, for example, to enable player input upon completion of a scene transition.

It is called just before the first ebiten.Game.Update after the game starts and after OnStarter.OnStart.

OnDeparturer.OnDeparture is called when a Transition is started to switch scenes. This is useful to disable player input at the beginning of a scene transition.

It is not called when the game is terminated by ebiten.Termination.

OnEnder.OnEnd is called just before ebiten.Game switches.

It is not called when the game is terminated by ebiten.Termination.

Parallel structure handles multiple ebiten.Games in parallel. The order of processing is constant.

Parallel.Layout calls all ebiten.Game.Layout and returns the largest return value.

• OnStarter, OnArrivaler, OnDeparturer and OnEnder are called by Sequence. Use Sequence to enable them.
• When switching scenes, ebiten.Game.Layout of the previous scene may be called. If the sizes returned by the previous and following ebiten.Game.Layout are different, the size of the screen passed to ebiten.Game.Draw after the changeover may be unintended.

Add the dependency with go get command.
