Hi,
if I understand, you want to store locally the user's scores. you would first need to learn and work with the playerPrefs system ( which saves locally data).
Or are you already past that?
The thing is, working with lists and arrays in playmaker is not built in so you need to hack it a bit, which makes it already an advanced feature to implement I am afraid...
Several ways out of it.
1:you maintain a simple text file that you present as is, each line showing a score.
2: more complex: implement a user pref key per score ( "score_12","score_13"), etc)
you also store the current score, ( say 13).
you then append a new score ( save it in user pref as "score_14" and save the new current score: 14).
you only want to store say 10 scores, so every time you add a new score you also delete from the user pref the oldest score ( 14-11 so that would be score_3)
then in your interface, you have one gui element per score, and you access the user pref like so: currentScore ( "score_14), the second (currentScore-1 ->"score_13").
As you are new to playmaker, look at the string actions, you can build string, constructs string in various ways to achieve the process above.
3: more complex: using ArrayMaker.
https://hutonggames.fogbugz.com/default.asp?W715I have created this utility to allow you to work with lists within playmaker. so it will be easier for you to work with list, But as you are new to playmaker AND Unity, this could add the learning curve...
so I suggest you first get acquainted with Unity and playmaker a bit more, then you'll start to find ways of working out the score board.
If you have trouble learning about one the feature I mentionned above, let me know, I'll detail more.
Bye,
Jean
