How to make a 2nd player in this racing game.

Question

I'm using this tutorial to learn how to make games in Flash for a class, but it doesn't say how to make a 2nd player.
If somebody can show me the code to make alternative controls (W,S,A,D) for a 2nd car that'd be fantastic!
Thanks a lot,
Dd

Answer 1

if (_root["car"+who].code == "player") {           
if (Key.isDown(Key.DOWN)) {
               this["speed"+who] -= _root.backSpeed;
          //steer left - well, we could simply add or subtract a fixed angle (in degrees) to/from the car's rotation, but that's not good enough. In order to simulate a natural movement, steering must depend on speed, otherwise you will be able to rotate your car even if it's almost stopped and it will look like a propeller
          if (Key.isDown(Key.LEFT) && this["speed"+who]>0.3) {
               _root["car"+who]._rotation -= _root.rotationStep*(this["speed"+who]/_root.maxSpeed);
          //steer right - you already know what happens here
          if (Key.isDown(Key.RIGHT) && this["speed"+who]>0.3) {
               _root["car"+who]._rotation += _root.rotationStep*(this["speed"+who]/_root.maxSpeed);
You basically have to make a second conditional clause that starts:
if (_root["car"+who].code == "player2") {           
if (Key.isDown(/*Insert KeyCodeValue of the Key you want to use*/)) {....
