Bricks aren't disappearing when hit with the ball

Question

I wrote the following code (within the while loop) but my bricks aren't disappearing. My ball just hits the bricks and bounces off. What am I missing here?

GObject object = detectCollision(window, ball);

        if (object != NULL)
        {

            if (object == paddle)
            {
                y_velocity = -y_velocity;
            }

            else if (strcmp(getType(object), "GRect") == 0)
            {
                 y_velocity = -y_velocity;
                 removeGWindow(window, "GRect");

            }
        }

Answer 1

The function removeGWindow() receives a GWindow and a GObject not a GWindow and a string. You should be removing object when it's a GRect other than the paddle!

Answer 2

The brick is the object that was returned by detectCollision(). That's what you should be removing in your removeGWindow().

For example, let's say you have a function didItBreak() that returns a GObject. You'd want to remove that object in your remove function:

GObject ballThrown = didItBreak(window, ball);
...
removeGWindow(window, ballThrown);
