Implementing the game loop with a thread

Now that we have learned about the game loop and threads, we can put it all together to implement our game loop in the Living Drawing project.

We will add the entire code for the game loop, including writing two methods in the LiveDrawingActivity class, to start and stop the thread that will control the loop.

Tip

Can you guess how the Activity-based class will start and stop the thread in the LiveDrawingView class?

Implementing Runnable and providing the run method

Update the class declaration by implementing Runnable, just like we discussed previously, and as shown in the following highlighted code:

class LiveDrawingView extends SurfaceView implements Runnable{

Notice that we have a new error in the code. Hover the mouse pointer over the word Runnable and you will see a message informing you that we need to implement the run method, again, just as we discussed during the discussion on interfaces and threads in the previous section. Add the empty run method...
