Multiple hot spots find them all question

As to button sets, forget the term button. Any items can be made into a set. Button is just a term of convenience. Select two or more items, right click, and choose Button set. Some things to remember:

• Only one of the set can be selected at any time
• Once one of the set is selected, you cannot deselect it except by selecting another
• Items will not show which is selected if they do not have a Selected state, unless you create another state and triggers to show it.
• There is no way to select part of an image, whether you want to click it, or use it as part of a set.
• An item can be part of only one set.

They are irreplaceable if you must have what they offer, but can require a lot of resource investment, if they are used just for fun.

There are some ways to easily make part of an image clickable.

The most glamorous (least useful, and most difficult) would be to insert a number of copies of the image. Crop them the smaller rectangles, and put the rectangles together, like a jigsaw puzzle. Each piece would be an independent object, and could be treated independently.

Easier methods are suggested by Tom and Judy: hotspots or shapes above the image. Remember, this is a visual medium, so nothing has to do what you want. It only has to look like it is doing it. If a learner clicks on an invisible item above the image, they think they are clicking on the image.

For what it's worth, I favor Judy's method of shapes. Shapes, without the baggage and limitations of hotspots, give me a lot more flexibility.

The attached sample shows two fairly simple ways to do what you are asking; one using states, and one using layers. Both of them show how they might work if the clickable spots are a set, or if they are not.

Yes, this is a business that requires a lot of painstaking attention to (sometimes) tedious detail, but that's what separates great results from good enough.
