Trigger to make buttons appear on base layer?
Jul 17, 2013
I have a hierarchical diagram (business structure) which is composed of buttons, each button triggering a different interactive slide. One button on this first screen is for an umbrella area, so I have made this trigger a layer which shows two areas/buttons underneath it.
The problem I now have is how to set my 'do not pass' rules. I started setting a true/false variable to identify when the screen interactions are complete, but then I realised this won't allow me to say when the two buttons on the layer have been visited. (By the way, I have tried this true/false variable strategy once and it worked, but when I tried it recently in another module which already used a true/false variable, it didn't seem to recognise it. Are there problems with using multiple variables in one course?)
I then thought that perhaps there might be a way of making the buttons appear on the base layer. Is this possible? I don't use any animations, audio or video, so I rarely use the timeline, and I don't want the buttons to just appear randomly. Any ideas?
