I am trying to create a shared action that I can use to: (1) skip the slide if the slide has been visited, (2) mark the slide as visited, (3) if a condition is true then change the state of an object to state 1 and increment a variable by one but if it is false then change the object to state 2 and not increment the variable.
If the slide has been visited, I want to skip it and not do anything else.
If the slide has not been visited, I want to mark it as visited, and then check a condition, depending on that condition it would do (i) change object to state one and increment a variable by one or (ii) change the object to state two and not increment the variable.
Why?
I asked the user a question, if they got it right I want to tell them that and add one to their score. If they got it wrong I also want to tell them and not add anything to their score. Either way, once I have asked the question and given the feedback, I do not want the user to be able to go back to the question or feedback slide. And I am using the skin viewer navigation. Therefore, I cannot eliminate the back button in those two slides (which would make it much easier).
In a normal programing language I could write:
10 If visited=1 then next_slide (and exit this program);
20 let visited = 1;
30 if answer=correct then xxxx else yyyy;
I cannot figure out how to do this with advanced actions and decision blocks.
Could someone help me on this?
Thanks.
