Physics Engines Pt. 2

[Editor's Note: Sorry this is incredibly small. QbProgger put this together really quickly, since he was quite busy in December.]

Create 2 rather large objects
Set a gravity on the y axis (gravity in real life is -9.8m/s so adjust for the character's height and the framerate of your engine) start loop
If the space bar is hit, set y acceleration to a number that seems reasonable. IF it's too high, the character will go offscreen, too low, the character will hardly hop. Experiment based off of your settings!
If the object's 2 bounding boxes collide, check to see if each object is in an attacking state. If both aren't they just collide with each other causing no damage. Otherwise, do damage accordingly, and do a pixel-perfect detection if you know how.
If one player is dead, round's over exit loop, otherwise keep looping

Simple enough, eh? :)

Next QBCM will feature a demo of this fighting game structure as well as an explanation of how to make a sidescroller with a physics engine!
