http://www.softschools.com/games/action_games/crazy_taxi/ Here's a version of Crazy Taxi if anyone hasn't played it. What I want to be able to do, but have no idea how to do it, is to create the same lane changing mechanic that Crazy Taxi has. I want the player to be able to tap the left or right side of the screen and have the character move left and right similar to changing lanes. Imagine a top-down car game that just moves forward (Up on the screen) and you have to tap left or right to change lanes to avoid oncoming traffic. I assume a simple mechanic like this would be possible in BB. If it is, please let me know how to do it.
