Darkened Movie Theater

Variables are amongst the most powerful features in Articulate Storyline 360. That’s because they allow you to capture and recall information throughout your project. Using variables, you can show content that’s based on the learner’s choices, activity, or quiz score—just to name a few options. E-learning designers use variables, along with states and triggers, when they need to create more engaging and dynamic learning experiences, like gamified courses or branching exercises that illustrate consequences.

Storyline 360 gives you three variable types to choose from: text, true/false, and number. In this article, we’re going to focus on the number variable.

I like to use number variables because they can be fixed or random values. Having this flexibility opens up lots of creative possibilities. For example, I used the random number variable to create the fun Storyline 360 movie trivia download, below. And I used it in two different ways. Can you spot them? Check it out!

Working with the Random Number Variable

One of the things that makes playing games so much fun is the element of chance—which is the perfect use case for the random number variable. I decided to use the random number variable to assign users a bank of randomly sorted trivia questions. Here’s how I set up the random number variable and then triggered it to direct learners to a random question bank.

Set Up the Random Number Variable

Once I determined the number of question banks I would need for my project (three), I had to set up a random number variable that would draw from a range of numbers between 1 and 3—to reflect the number of question banks in my project.

My trivia question banks were grouped by decade into three individual scenes: the 1970s, 1980s, and 1990s, so I chose to call my new variable “RandomDecade.” I then assigned it a range of numbers from 1 to 3, again to correspond to the number of question banks in my project.

Here’s how it looks in Storyline 360:

Setting up the random number variable

Create Triggers

With my new “RandomDecade” random number variable ready to go, I needed a way to trigger that variable. Following are the steps for creating those triggers.

Step 1: I inserted a slide that prompts the user to select a game piece or avatar to represent them in the game. Once the user clicks on their selection, it takes them to a layer where their game piece is confirmed and they’re prompted to search for a random question category (i.e., 1970s, 1980s, or 1990s movie trivia).

When the learner clicks the “Search” button, this jumps to a third slide layer where the random number variable is triggered as the layer loads. Here’s how that trigger looks in Storyline 360.

Step 2: With that random number triggered, I needed to direct learners to the question bank scene that corresponds to the value of the random number variable. To do this, I added another layer trigger—but this time with a condition. The trigger I chose is a “Jump to Scene” trigger, set for when the timeline ends. The logic for the condition I assigned to each trigger is as follows:

  • Quiz Bank 1 is for 1970s movie trivia, so I wanted to direct learners there when the random number variable equaled 1.
  • Quiz Bank 2 is for 1980s movie trivia, so learners should be directed there when the random number variable equaled 2.
  • And Quiz Bank 3 is for 1990s movie trivia, so I wanted learners directed there when the random number variable equaled 3.

Here’s how it looked in my project.

Using the Random Number Variable to Simulate Other Players

Another thing that makes games so much fun is the ability to play against other people! (That’s why so many games give you the option to play against a computer player, so you can still have that sense of friendly competition even when you’re playing by yourself.)

To mimic that feeling of friendly competition, I decided to simulate two other “players” in the game. When you start the game you are, by default, Player 1, and whichever game pieces you don’t select are assigned to Players 2 and 3.

The game piece selection on its own creates a pretty cool effect, but to take things a step further, I decided to use the random number variable once again—but this time I used it to make a dynamic quiz results slide for each question bank. I customized these results slides to look a bit like a leaderboard showing a “score” for all three players in the form of an animated bar chart. The bars depicting the scores for Players 2 and 3 (who are simulated players) were randomly changed using—you guessed it—the random number variable!

Here’s how I set that up in Storyline 360.

Step 1: After inserting a graded results slide and removing all the elements, I laid out the vertical scoring bars for my chart and added the game pieces for all three players. At this stage, the results slide looked something like this:

Setting up the score bars

Step 2: I drew a rectangle (located under Shapes on the Insert tab) and added a fill color but no border. I drew my rectangle very narrow—just about five pixels wide. I positioned the rectangle as close to the zero scoring bar as I could. Then, with the rectangle selected, I clicked Edit States and then the New icon. I added four custom states to this rectangle, labeled 25%, 50%, 75%, and 100%. I then stretched the rectangle for each state to its corresponding scoring bar. Here’s how the bar states looked when I was done:

Scoring bar states

I repeated this process for the other simulated player, changing the color fill.

Step 3: I want to assign a random score to my simulated players, Players 2 and 3. To do that, I set up two new random number variables—Player2Score and Player3Score—with a random number range between 0 and 4. Using some triggers and conditions, a random variable range of 0 to 4 will allow us to change the state of the rectangle bar dynamically, so it shows the simulated players’ scores varying from 0 points to 100 points.

Here’s how my new Player2Score variable looked when I was done:

Player Score Variable Set-Up

Step 4: Now it’s trigger time! First, I added a slide trigger to fire off the Player2Score and Player3Score random number variables when the slide loads.

To set this up, I simply added a new trigger to “Adjust variable” and selected Player2Score or Player3Score from the variable dropdown. I then set the value to be a random number between 0 and 4.

Here’s how this looked when I was finished setting up the trigger for Player 2:

Adjust variable triggerAnd here are both slide triggers in my triggers panel:

Slide Triggers

Step 5: Now it’s time to add some more slide triggers to change the state of the score bars for Players 2 and 3 to get that dynamic scoring effect I was looking for.  To do this, I needed four triggers for each player score bar, as follows:

Changing states

Using this combo of random number variables to generate scores for the simulated players, and object states, triggers, and conditions, the Player 2 and Player 3 score bars will change their state dynamically, contributing to the illusion of other players in the game.

Putting It All Together

When all is said and done, Player 1 can play again and again, getting up to three different, randomly assigned banks of trivia questions, each with five randomly drawn questions, AND will see totally different scores for the other players at the end of each quiz. Now we’re a little closer to a more game-like experience!
