Combined Total of Different Variable Values
Hi. In my game for every second you survive you get a point. This is your score. You receive a score every time you play. You also have a high score. Now what I want to do is for every point you get you also get a coin. My problem is when I display your money amount on the menu it is just what you score last round. How can I make it so that your money amount is a collective total value of all your scores? Here is the code I am using to display your money amount which is the same as your score:
Saving the money amount:
PlayerPrefs.SetInt ("moneyAmount", score);
Displaying it:
private int moneyAmount;
public Text moneyamountLabel;
// Use this for initialization
void Start () {
moneyAmount = PlayerPrefs.GetInt ("moneyAmount");
moneyamountLabel.text = moneyAmount.ToString();
}
Any ideas? Thank you! :)

It seems like when you save moneyAmount to PlayerPrefs, you need to add score to the value already stored there.
Something like
int accountBalance = PlayerPrefs.GetInt( "moneyAmount" ) ;
accountBalance += score ;
PlayerPrefs.SetInt( "moneyAmount", accountBalance ) ;
@Victory Dan Greene Hi. Thank you for responding. It is much appreciated. Anyways, your methods works perfectly!! The only flaw is that if the score is over 2 it will start increasing the money amount by a certain number.
+1
+3
+6
+10
So for example if I score a 3 my money amount will be 3 plus 3 so it will be 6. Any ideas as to why this happens?
It sounds like you're running the "save" routine more than once... $$anonymous$$ake sure you're only running that once, when the play session ends?
(edit) alternately, maybe you're adding score to the "moneyAmount" PlayerPrefs every time the player gets a point? In that case, you want to add 1 ins$$anonymous$$d of score.
@Victory Dan Greene Hi. Thank you for your response. I would like to extend my sincere apologies, but am so confused and I am such a newb. How would I do these things?
One idea is, just before the line
accountBalance += score ;
add the line
Debug.Log( "Score was " + accountBalance + "... adding " + score ) ;
And keep an eye on your console to see when this routine is being run.
@Victory Dan Greene Hi. Sorry for the delayed response. Can I contact you after the holidays via this question post? It would mean a lot. Thank you very much and have a very nice holiday!

You should check to see if moneyAmount is set, if not set it to score. If it is set, fetch that value and set moneyAmount to that value plus score.
@HYPERSAVV Hi. Thank you for answering. I am kind of a newb so how would I check to see it is or is not set?
Refer to the documentation for PlayerPrefs
if(PlayerPrefs.Has$$anonymous$$ey("key"))
{
// That key is set, do something
}
In your case though, this will technically work whether you check if the key exists or not. GetInt will return 0 by default if the key does not exist (or any other value defined as the second parameter). For your program 0 would be an acceptable score for someone who has never played. There are other scenarios where we would want to know if we have set a key or not, which you could use this for. Something to keep in $$anonymous$$d for later :)
