An example backdrop
You should add in cars and edit the track as shown here when it is finished. There is an example of this here.

A player vs player racing game is a project that lets one compete in racing against their friends.

Sprite 1

First create a new sprite, then change the costume to a car in the sprites library where there are sprites, add a if <> then block, then a Point in Direction block, then add a Move () Steps block. It should look like this:
 if <key [right arrow v] pressed> then
point in direction (0 v)
move (10) steps
end

Continue to do this with the left arrow, down arrow, and so on. Then, place the scripts in a forever block, and under a when green flag clicked block. It should look like this once you are finished:

when gf clicked
forever
if <key [right arrow v] pressed> then
point in direction (0 v)
move (10) steps
end
if <key [left arrow v] pressed> then
point in direction (-90 v)
move (10) steps
end
 if <key [down arrow v] pressed> then
point in direction (180 v)
move (10) steps
end
if <key [up arrow v] pressed> then
point in direction (0 v)
move (10) steps
end
end

Sprite 2

For the second sprite, get another car from the sprites library. Do the same thing as you did with sprite one, only using the W (up), A (left), S (down), and D (right) keys. Once finished, it will look like this:

when gf clicked
forever
if <key [w v] pressed> then
point in direction (0 v)
move (10) steps
end
if <key [s v] pressed> then
point in direction (180 v)
move (10) steps
end
if <key [a v] pressed> then
point in direction (-90 v)
move (10) steps
end
if <key [d v] pressed >then
point in direction (90 v)
move (10) steps
end
end

Backdrop

Now, time to move on to the backdrop! First go into Paint Editor. Paint a backdrop, but do not forget to paint a black and white finishing line, as it will be needed. You will need this to finish the game.

Sprites

Once the backdrop is finished, add the following code to both sprites:

when gf clicked
forever
if <touching color [#FFFFFF]?> then
say [I win!]
end
end

Instructions

Sprite 1 will move with the up, down, left and right keys, and Sprite 2 will move with the W, A, S and D keys.
