Save Game confusion

Thanks everyone very much

For my own clarity, is using this plug-in a way around doing any coding such as the examples given?

If the plug in does not remove the need for manual coding and given that there is already a save system for games on dashingdon then I am not sure what it is for? To be clear, I am not trying to be annoying - I actually am this thick! (as some of you will know from my other queries and issues!)
