MongoDBreakout- Strange collisions

[Cborek]

Occasionally, the ball has clipped straight through the paddle upon hitting somewhere near the center. While I have been able to replicate the issue a few times, I'm still not sure of the exact circumstances that cause it. Though it seems to happen most often when the paddle isn't moving. I have noticed that when this happens the ball behaves as if it has hit the side of the paddle by bouncing in but continuing downwards. Perhaps it's something to do with the new changes?

I've also noticed that the ball will occasionally pass straight through a block without any sort of reaction. I haven't been able to find any specific circumstances that cause this to happen. As far as I can tell it occurs randomly.

Failed Test Case: MB-13, MB-14

@Cborek Thanks, I can try to reproduce it. Would it be possible to catch it on a screen recording video, or is that too much to ask? The whole game animation system is just one big loop that uses requestAnimationFrame and a canvas, so my best guess would just be that any strange behavior would be from a slight lag in the browser where some code was delayed at just the right time to cause a hard to reproduce issue. I can look through the hit detection code again to see how I can improve it, but it may just be a browser thing that I don't really have control over.

For the blocks, yeah it's possible that if the ball hits a block at an angle that it just passes right though it and destroys the block without bouncing. I'd need to go back and look at the code, but I think I'm only doing hit detection on the top middle and bottom middle of the ball, so if it hit a block at an angle from the side it's possible it wouldn't bounce. I kind of liked this behavior since that's similar to what can happen in the original Breakout, so I intentionally left that one in.

@thawkin3 I'd be happy to try to get it on video. I'll also try to replicate the bug on different browsers to see if that changes anything. Currently, I'm using chrome.

When it comes to the blocks I actually agree that the ball passing through the blocks is kind of interesting. I honestly think that this one might improve the game if left in.
