Adding a second player
Driving around the circuit on your own is fun but not very challenging. It would be much
beter if you could invite a friend to compete against. In this step, we will introduce a second
player character. Both characters will be visible on the same screen and will be controlled
with one keyboard. We're efecively building a simple form of muliplayer.

To create a second player, we mainly have to copy the work we've done already. We need a
second control sprite and a second kart sprite. We already added a Mario sprite to the game,
so let's bring in his brother Luigi as the second player:
1.
Right-click on the control sprite named
player1
and choose
duplicate
.
2.
The copy will be called
player2
automaically. If that's not the case,
change the name manually.
3.
Go to the
player2
Scripts
tab.
4.
Change the
key pressed
controls from
a
and
d
to
left arrow
and
right arrow
respecively.
The other script works exactly the same as for the
player1
sprite.
Copying the sprite can cause some trouble with the variables. So let's make a new
speed variable to be used for the second player sprite. We will name this
speed2
.
We also need another kart costume set. Instead of a guy in red, let's make the second
player a guy in green:
