Time for action – pausing the game with a pause dialog


We will start with adding a pause dialog to allow the player to pause the game:

  1. Create a new group in Resources and call it Dialogs. Then, open the book's supporting files in Chapter_09/Assets/Dialogs and add all the images to that group.

  2. Create a new Objective-C class in the Scenes group. Name the class PauseDialog and make it a subclass of CCNode.

    Tip

    Note that it is a subclass of CCNode not CCScene. We have used a similar approach when we created the HUDLayer class. You can read Chapter 6, Rendering Text, to refresh your memory. We are going to use CCNode as a base class for all dialogs.

  3. Open the PauseDialog.h file and add the following property. It will allow the object, which creates the dialog to be notified when the dialog is closed.

    @property (nonatomic, copy) void(^onCloseBlock)(void);

    Note

    If you are unfamiliar with blocks, I suggest that you read Apple's documentation at https://developer.apple.com/library/ios/documentation/cocoa...
