Tiles with Building Text - Layers or Selected State?

It looks like Walt answered while I was prepping my answer. Well, here's what I was going to say:

In the version with layers, the transitions would be smoother if (1) you make the color image exactly match the size/placement of the black-and-white image, and (2) you add Entrance Animations to the color images and/or add Transitions between the layers.

You can simplify the slide if you want the user to be able to click in any order: 

• The "buttons" on the base only need a Normal state.
• Delete the "Tile # Active" layers. They aren't needed. As long as the Slide Layer Properties are set so they don't hide other layers, each "Back Tile #" layer will show when the corresponding button is clicked, and it will remain on the slide. 
• Use T/F variables to track whether each layer has been shown.
• Add a trigger to each layer that changes NEXT to Normal when the layer's timeline ends with the conditions that all of the variables = True. 
  • Also add conditions to the trigger that disables NEXT to ensure it won't be disabled again if the user returns to the slide. 

This is shown in the attached file. 

Preview it with the text box still on the stage, to be sure it is working as you want. Then paste into the state.

For states, you can use entrance animations. Create the desired text box, set the animation, then copy the text box, edit states, and paste the text box onto the selected state. Check this, it’s possible it might work only the first time, but not later times if the learner clicks back and forth. In fact, the drawback to using Selected states is that they toggle; another click will change it back to Normal. If you don’t want that behavior, use a custom state (and a name that is not on the drop down list), and a trigger to change to it when the object is clicked.

If you use layers, you will need one for each card, and set their properties to de-select the “Hide other layers” function.

Thanks so much, Walt and Judy! Appreciate the benefit of your experience.  I've been using Articulate for our annual training for 5 years, and each year, we use a different interaction to keep it fresh. Each year, I build my knowledge bank (but need my own refresher after 8 months of not using it!). 

Judy - the images are just placeholders for now. They will match perfectly for the final version - I should've mentioned that! :)
