Emit "actionstart" and "actioncomplete" events

[mattjennings]

It would be useful the ActionsComponent emitted events when starting/completing actions

Context

I have a moving platform that has its path defined by actions

    const platform = new MovingPlatform(
      {
        x: 300,
        y: 50,
        width: 100,
        height: 16,
      },
      (actions) =>
        actions.repeatForever((builder) =>
          builder.moveBy(0, -50, 40).moveBy(0, 50, 40)
        )
    )

I have some particular logic that I need to run whenever the platform changes direction that should happen immediately after the velocity is changed. Hooking into an event would be a very nice way to solve this.

Proposal

Action component the following events containing the relevant action:

• actionstart
• actioncomplete

These can be either on the actor or the actions component, or both? This would also fire for each action in repeatForever etc.

type ActionStartEvent {
    action: ex.Action
}

type ActionCompleteEvent {
   action: ex.Action
}

this.on('actioncomplete', (ev) => {
   
})
