In this video, you'll remix this game
so that a second player can control
a chaser using key press events.
To start, select a chaser spray.
This spray is going to do something
different from the other chasers so rename it player two.
To program the chaser to move with key press events,
remove only the code that moves the spray
and leave the if statement that checks
if the two sprays are touching.
Next, program events to move the sprite forward, backward,
left and right when a second player presses the arrow keys.
This video will fast forward through addition
of these blocks, but when you create this code,
remember that you need to add four events,
four motion blocks, and if you want the sprite
to run smoothly, a repeat until not
pressing code stack for each event.
After you code all four events,
tinker with the sprite speed by changing
the value of the move 10 steps block.
Play around with those values until player two
moves slowly enough to make the game fair.
It may take a few tries to get this right.
A big part of computer science is trying new things.
Testing them, then going back to tinker
with the code until you're happy with the result.
Now it's your turn.
Program events to move the sprite forward, backward,
left and right, when a second player presses the arrow keys,
then tell users how to work your program using
either a save log or instructions in the project page.
One you've finished programming your game
for a second player, ask your neighbor to try it out.
