Make a Boolean Variable to Track Whether the Chest is Open

In the next steps, we’ll add code to close the chest lid again. In order to do that, we need a variable that keeps track of whether the chest is currently open.

1. Above the start function, create a new private variable named isOpen.
2. Set it to false initially.
3. In the openChest function, set it to true in the else-statement after the animation finishes.
