    addcoins();
   

}
 private void Update()
 {

//   

}
public void addcoins()
{
  
    
        gettingvalue = treetry.instance.finalscore;
        currentvalue += currentvalue + gettingvalue;
        totalvalue += currentvalue + totalvalue;
        cointext.text = totalvalue.ToString();
        PlayerPrefs.SetInt("totalcoins", totalvalue);
        PlayerPrefs.GetInt("totalcoins", totalvalue);

HI !! @truedreams !

First, where you say

     currentvalue += currentvalue + gettingvalue;
     totalvalue += currentvalue + totalvalue;

i think you are not doing what you really want. The symbol += means “add to current value”.

For example, if we have x=1 an do this:

x += 3;

Now x = 4. But you are not doing this, you are increasing itself + another value. In your code, you are doing this:

 x += x+3;

So now x=5.

So… i supose you wanted to do this

currentvalue +=  gettingvalue;
totalvalue +=  totalvalue;

I mean next 2 lines are exactly the same:

x = x + 3;
x += 3;

And if it increases only by one, next3 lines are the same:

x = x+1;
x += 1;
x ++ ;

In other hand…

What program are you using for scripting?

Do you know how to debug the code while running the game

Debug means, the code is monitored, and you can mark code line, and when the game try to read and execute that lines, it stops, and allow you to check the state of your variables, to see if they are as its supposed they has to be. This allow you to check if a method is called, or how the variables changes.

If you are having problems operating with variables, debugging is your best friend! If need more help just ask concrete questions and we will help you !
