Articulate Storyline encourages you to be an escape artist. Some of the more complicated projects may seem like you’re in the jungle of variables, triggers and conditions. The following trick may help you escape the jungle (somewhat) faster than normal.
Before we get into the how, I suggest you play the Escape Game first. This is not really a game but more like a gameful example of using some magic behind the scenes. Watch how the “codes” behave. I can’t tell you more about it. You need to figure it out to escape.
Let’s assume you have buttons on the screen the user can toggle. You want the user to toggle AT LEAST two of them on. You don’t care which ones. This is a simplified version of the game above. In the escape game, you had multiple states of a button (showing different icons). In this business problem, you have only two states: on and off. Once the user toggled at least two of them on, they can move on. You will need to retain those selected buttons later on, maybe doing some branching or conditional content.
Here comes this framework that handles your problem a different way. Imagine that you could store values (0,1) in one text variable, separated by a character like “|”. So, Switches variable could have the value of “1|1|0|1|” where each number represents an on or off state.
Then you could issue commands like: flipItem(“Switches”,0);
This would toggle the first item (geeks start counting from zero): Switches would be now “0|1|0|1|”
You could get the total number of 1s by issuing: countAllItems(“Switches”,”TotalOn”);
This would count how many non zeros you have in the Switches (“0|1|0|1|”) text variable AND set the variable TotalOn to that number. In this case, TotalOn would be 2.
Since you store all values in one variable (Switches), you can use the change on this variable as a trigger. That means any time someone toggles a button (it doesn’t matter which one), your trigger fires. Moreover, let’s say this is a True/False type of puzzle. On means True, off means False. You ask four questions and the user toggles the buttons according to the answers (let’s say true, true, true, false). You can check the answer with one condition using the Switches variable and compare it to the “1|1|1|0|” value.
