Pset3, detect collision, paddle not ‘colliding'

Question

I used the code given in the set

GObject object = detectCollision(window, ball);
if(object !=NULL)
{
  if(object== paddle)
  {
   y_velocity=-y_velocity
  }
}

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

after that I check to see if it is bouncing off the sides...

This is all within the while loop, but when I run the breakout.c, the ball doesn't bounce / deflect until it reaches the bottom of the window. :(

Oddly enough, the code to detect for GRects (if(strcmp(getType(object), “GRect”)==0)) does bounce off the bricks at the top. I got rid of the (object==paddle) part of the code and only checked for GRects (and made the y-velocity change), but the ball still didn't deflect from the paddle, even though it still did for the bricks?? It’s like the code doesn't know that the paddle is an GObject / GRect? Any suggestions??

Thanks!

Answer 1

I had this problem before, and I did exactly what you tried to fix it. The part about your paddle is (somewhat) correct. (Somewhat because it has nothing to do with the ball bounces off the paddle or not, it is another issue)

Your issue lies somewhere in the lower part with (strcmp(getType(object), "GRect") == 0). Perhaps you should post that part up here so people could give you some ideas how to fix it.
