Commit the Bug Fix

Leave 'detached HEAD' state

Right now, your HEAD should still be 'detached' from Lesson 1 when you checked out an old commit. To fix that, run the command git checkout master. You'll learn more about what this command does later this lesson.

Fix the delay bug

Now, if you were following along with Caroline, you may have already fixed the bug in the Asteroids repository. If not, go ahead and make the change and add it to the staging area now.

In game.js find the statement
if (this.delayBeforeBullet <= 0) { (should be on line 423). On the next line, insert
this.delayBeforeBullet = 10;

Stage your change

Then stage your change by adding the game.js file to the staging area. If you’re having trouble remembering how to stage changes, use this video as a refresher.

Commit your change

Now, go ahead and commit this change. Make sure to use a meaningful commit message! If you have trouble remember how to commit, refer to this video.

When you’re finished committing your change, click “Next”.

INSTRUCTOR NOTE:

You may notice that our commit id is different from yours, even though we made the same change, while the commit ids up to this point have all been the same. That’s because if there is any difference between two commits, including the author or the time it was created, the commits will have different ids. Check out this page if you’re interested in learning more about Git internals and how commit ids are generated.
