Show 'hint' after clicking the wrong place on the screen three times

I would use advanced actions (of course).  But have to know if this is a responsive project or not. Reason: in CP2017 you cannot have two objects stacked when developing a responsive project with Fluid Boxes.

You need to put a click box behind the first button, that click box should cover the slide. You can use the Success event of that click box to do what Jeremy explained with JS. It is up to you, but first have to be sure about the type of project.

You can do this with javascript or advanced actions / or a combination.  But essentially you will need to create three things:

1. An 'invisible' button over the incorrect area

2. A variable that goes up incrementally each time you click

3. An if statement that is triggered on each increment / button press.  This statement would 'check' if you reached the number of clicks. 

I prefer to use javascript over advanced actions so this would be how I do it. 

1. Under Project -> Variables, create a new variable title 'clicks' and give it a value of '0'

2. Create a text hint and title it 'msg'.  Make it hidden by clicking on the eye icon.

3. Create your invisible button shape over the area that will trigger the clue.  On this invisible button execute the following:

clicks = clicks + 1;

if (clicks == 3){

cp.show('msg');

}

If you want it to be more clicks just change the '3' to whatever value you want.  Hope this helps.
