State Changes for Buttons on Master Slide
I'm working on a course in which learners must diagnose and fix one or more safety problems on each of several devices. When the learner solves all of the problems associated with a given device, I want to put a checkmark over it so that the learner can know to concentrate on fixing problems with other devices and not devote any more time to the one(s) whose problems have already all been fixed.
I put the checkmark over each device and start it in the Hidden state. When the learner solves all problems associated with that device, I have a trigger that changes the state of the checkmark to Normal to make it visible.
My problem is that, because of the complexity of the interactions, I branch to a new slide whenever the learner clicks a device. To add layer triggers to check whether each device's solution criteria have been met and set the appropriate checkmark to the Normal state on each slide, given how many devices I have and how many slides I branch to where these checks would need to be placed, I'd end up having to add about 30-40 triggers. I don't want to do that.
So instead, I want to put the checkmarks (and the triggers to change their states) onto the master slide instead. But it's not working. The checkmark appears when the learner solves the problems for a given device, but when he or she clicks the next device, the checkmark disappears, even though both device slides use the same master slide.
Because my actual Storyline file is pretty heavy-duty, with multiple triggers and multiple layers across multiple (branched) slides, I've created a much simpler example file. The published version is here:
The Storyline 360 file is attached.
Can anyone explain why the checkmark for a given device, once turned to the Normal state, doesn't stay there for all slides that use that same master slide? Am I misunderstanding how master slides work?
