Button reset

Sorry Claude, I dont read French so its very difficult for me to understand whats going on in the Storyline file you sent.

However, if you just want the Menu page to reset when all missions are complete but the Result is failed, then you can still use the T/F variable method.

Simply create a T/F variable called "MissionFailed", and have it set to FALSE by default.

Set this variable to TRUE at the correct time when the user fails Mission 7.

On your MENU slide, you can have a trigger to reset everything if they fail. This trigger would look like;
Change State of MISSION 1 BUTTON to Normal when the timelines starts on this slide IF <missionfailed> = TRUE.

Do this for the remaining two mission buttons and you now have a working reset.

NOTE - You dont specify whether the user can complete the three Missions in whatever order they want? If they have to do them in order 1,2,7 - this solution will work as is.
If however, you want them to be able to do whatever order they want, then you will need some additional triggers and variables to hold the value 0/1/2 for each question:
0 = unattempted (default)
1 = failed
2 = passed

Is that any better help?

Bonjour Claude!

Its not quite a miracle, but to get this to reset should be quite straightforward.

How I would do it, is firstly, set your MENU slide properties to "Reset to Initial State" When Revisiting

Then set up a simple T/F variable for each mission.

At the start, set all 3 variables to FALSE.
When the user gets the mission correct, set the variable to TRUE.

Finally, add a trigger to the MENU slide which says
Change state of MISSION1 BUTTON to State "Completed" when Timeline Starts on This Slide

And if you copy that same trigger for MIssion 2 and 7 buttons then this should work great.

The slide will show if the missions are complete, but if not, then the button will stay shown in the "Normal" state.

Does this help at all?
