3D Game Programming for Kids, 2nd Edition

Scoreboard

We’ll want to keep score in this game so, in the code outline at the top of our code, add a call to the addScoreboard() function.

​var​ ground = addGround();
​var​ water = addWater();
​var​ scoreboard = addScoreboard();

But there’s no addScoreboard() function yet, so this temporarily breaks things. To quickly get everything back, add the function after the last curly brace in the addRiver() function.

​function​ addScoreboard() {
  ​var​ scoreboard = ​new​ Scoreboard();
  scoreboard.score(0);
  scoreboard.timer();
  scoreboard.help(
    ​'left / right arrow keys to turn. '​ +
    ​'space bar to move forward. '​ +
    ​'R to restart.'​
  );
  ​return​ scoreboard; ...
