Physics/collision + game mechanics + sound

[Jjp137]

Okay, this is a lot. Maybe a bit too much to take in for one pull request :\ Just make sure you read all of this :)

First of all, everything that's in Brian_Collision is in this pull request, so you don't need to merge that branch.

And I don't even know where to start, so here's a list of bullet points:

• The simulation state uses the Farseer physics engine
• There are now breakable platforms, treasures, and death traps, and the goal now works
• The launcher has a power meter, and so the magnitude can be set
• The number of maximum attempts that a player can use is taken into account
• An attempt ends if the ball has no velocity
• There's text displaying how many balls you have left, as well as placeholder "you win" and "you lose" messages
• Statistics, such as the time spent and the number of treasures collected, are gathered as you play
• Collision detection with all the types of level objects works
• A UnitConverter static class to help with converting from meters to pixels, and vice versa
• Sound effects (taken from Freesound)
• Made the Simulation's properties less accessible (it's the Editor that should be really changing things around)
• More unit tests
• Some usage of events
• Way too many comments :p

...and other things that I usually end up forgetting.

And a few caveats:

• Resizing a Platform that has had InitBody() called on it is not supported at the moment
• The number of attempts is still hard-coded for now
• I think that we need to do a deep copy of all the Level's objects, but I have no idea how...
• Goal.cs, Treasure.cs, DeathTrap.cs, and possibly other files have a ton of duplicate code

I wouldn't be surprised if there are merge conflicts... Phew!

But yea, this is a lot of code. Take your time reviewing this, because this is an important part of the game. 90% of the code is from the physics engine, though, so skip that part :p

Before I forget, I got the sounds from here:

• http://www.freesound.org/people/iwilldstroyu/sounds/65787/
• http://www.freesound.org/people/davidou/sounds/88451/

And the sound part was easy to do :)

Wow! I'll take a look at this soon.

[Jjp137]

Okay. I'm actually going to make another commit in the next hour or so to fix a subtle (but potentially really annoying) bug. Gah, the physics engine...

[Jjp137]

Alright. I hope I didn't break anything else in a subtle way...

Everything looks pretty good. There are a number of architectural things I'd like to change, but it isn't spaghetti and all the functionality is there. Great work!

Unfortunately, I'm having a lot of trouble with my local Windows installation. I try to checkout a branch, or merge this one, and it tells me that certain files can't be unlinked. I'm going to merge this in via GitHub, but I won't be able to do anything with it locally for a little while longer.

Thanks! Feel free to iron out all the kinks in the architecture :) and that's a bizarre error... :\
