yOffset and the while loop continues to search for a black pixel.
It will do this until it finds a black pixel above the x coordinate of our
avatar, adding 1 to the yOffset variable each time. Once a black pixel
is found, we’ve discovered where our platform ends and can subtract
the yOffset from player[“y”] to put our avatar just on top of the
platform; this is done on line 73. If we don’t find a black pixel before
we reach the top of the surface, it’s game over: our avatar is trapped
off screen.
Moving our character left and right is done on lines 82-92. If the
code looks familiar, it’s because we used it in our last tutorial to move
our squares around. Now that we’ve worked out where our avatar can
go, we can draw it by calling drawPlayer() on line 203.
Game over
We’re almost done; the last thing we want to handle is what happens
when our player loses the game. The game is over once our avatar
disappears off the top of our screen, and we want to tell the user that.
When our avatar disappears, we call the gameOver function on line 79.
All the gameOver function does is set some variables that our main
loop will check to see if the game is underway. Once gameEnded is True
and gameStarted is False, our main loop will draw our game over
screen. Just like our welcome screen, we draw our game over image
onto the surface on line 193 and give the player the option to restart
the game with another space bar press.
And that’s it! Using all the skills we’ve already acquired (and a few
new ones), we’ve built our first fully fledged game. Like all good games,
we’ve got a start, a middle, and an end.
Left Just like our
start screen, our
game over screen
is simply an image
drawn straight onto
our surface when
we need it
