Recap: Door States

Part of the Game Architecture in Unity section of Coddy's Unity journey. Lesson 41 of 64.

This chapter gave each state a class of its own, ran them with one StateMachine, and let every state decide its own way out. The door puts the three together.

Challenge

Medium

Fill in the castle door's five states in DoorStates.cs; Door.cs has the helpers.

Locked: door.PressedNear() logs Locked. Door.Unlock() changes a locked door to closed.
Closed: PressedNear() changes to opening. Opening: once door.SlideTo(door.openY) is true, open.
Open: after door.stayOpen seconds, closing.
Closing: PressedNear() opens again; else once SlideTo(door.closedY), closed.

Press Play, fetch the key and open the door. Then Check.
