Hi,
-- the game should have the answers already written, this will be easier for you to create and manage at runtime.
-- ArrayMaker, xmlMaker: study the provided examples, it's quite advanced, so take your time, and progress one step at a time, first playing with just playmaker, then when you need lists and rich pre defined content, then you can tackle arraymaker and xml maker.
again, you can do this without arrayMaker or XmlMaker. simply have a prefab that holds the question and the answer, then create as many as you want in your scene, and turn them all off, then active the first one, let the user answer, if correct deactivate and move to the next one.
you could actually have all of them activated and placed next to another and have the camera move to the next one, then you have everything hardcoded ( easy to build when you are a beginner) and a nice camera animation from one question to the other.
bye,
JEan
