Why Do I Get a Segmentation Fault When Trying to Move the Paddle?

Question

I am trying to get the paddle moving with the mouse but I keep getting the same error message : "Segmentation Fault (Core Dumped)".

This is my function, which is very simple. Any suggestions?

// keep playing until game over
while (lives > 0 && bricks > 0)
{

    // follow mouse forever
    while (true)
    {
        // check for mouse event
        GEvent event = getNextEvent(MOUSE_EVENT);

        // if we heard one
        if (event != NULL)
        {
            // if the event was movementc
            if (getEventType(event) == MOUSE_MOVED)
            {
                // ensure paddle follows top cursor
                double x = getX(event);
                double y = 500;
                setLocation(paddle, x, y);
            }
        }
    }
}

Answer 1

You get a segmentation fault when you touch locations in memory that you shouldn't! Make sure your initPaddle() function doesn't return NULL and returns the paddle you created within it instead!

Answer 2

Take out that while(true) loop. It's enough with the while (lives > 0 && bricks > 0)
