Allow Free Navigation after Course Update

To solve the task, you will need JS. I have prepared a sample code that should work (but I cannot guarantee this, you need to test it in your LMS). You need to create a text variable called resultcourse. When the course starts (right at the beginning on the first slide), you should add a few triggers.

The first trigger - start the JS code when the slide's time begins and copy the code I added below. The second trigger (more likely several triggers) - when the variable courseupdate changes - you need to unlock the course menu (I don't know exactly how you lock and unlock navigation in the course) if the value of the variable resultcourse = completed.

I haven’t tested the code myself, so I cannot guarantee it will work, but this direction for finding a solution should definitely work.

var player = GetPlayer(); // Getting the Storyline Player object

// Function to find LMS API
function findLMSAPI(win) {
    if (win.hasOwnProperty("GetStudentID")) return win; // If API is found, return
    else if (win.parent == win) return null; // If this is the top level, return null
    else return findLMSAPI(win.parent); // Otherwise, continue searching in the parent window
}

// Initializing LMS API
var lmsAPI = findLMSAPI(window);

if (lmsAPI) {
    // Getting the course completion status
    var completionStatus = lmsAPI.GetValue("cmi.completion_status"); // Requesting completion status

    // Logging the status to the console
    console.log("Course completion status:", completionStatus); 

    // Saving the status in the text variable resultcourse in Storyline
    var result = (completionStatus === "completed") ? "Completed" : "Not Completed"; // Formatting the status
    player.SetVariable("resultcourse", result); // Setting the variable value in Storyline

var currentCourseUpdate = player.GetVariable("courseupdate");

var newCourseUpdate = currentCourseUpdate + 1;

player.SetVariable("courseupdate", newCourseUpdate);
