I need to get a total value in an Array, but i can't do it :/

I need to get a total value in an Array, but i can't do it How can i do this?

 

You can use LINQ. It depends on what your array contains. If it's an array of numeric values (like int) you can do this:

Code (csharp):

1.  
2. var total = myArray.Sum(itm => itm);
3.  

In this case "itm" is just a variable the represents each array element. But now let's say your array is actually an array of Vector3's and you want to sum up the "x" positions (just using it as an example);

Code (csharp):

1.  
2.  
3. var total = myArray.Sum(itm => itm.x);
4.  
5.  

That will return the total sum of the "x" property of the objects in your array.

 

Show us what you have tried.

 

You can set the values of the arrays and then just use a FOR to count the values. I would do somethin close to this (untested code):

Code (csharp):

1.  
2. for(i=0;i<nameOfTheArray.lenght;i++){
3.     total += nameOfTheArray[i];
4. }
5. print(total);
6.  

 

I got dynamic float values which can change at each frame. So i figured this out, and works fine. Thank you all for your help

Code (csharp):

1. for(var i=0;i<comps.length;i++)
2. {
3.         total += comps[i].inputValue;
4.  
5.         if( i == 0)
6.         total = 0;
7. }
8.     print(total);

 

That doesn't look right. You're adding in the value of the 0'th element to the total, but then immediately zeroing the total. So, you'll end up with a total that doesn't include the value of the 0'th element. I assume that's not what you want, is it? I'm not sure what you're trying to do with the "if" statement. Maybe you're just trying to ensure that the total starts out as 0? In that case, just set it to zero before entering the loop...

My opinion is just like your words. Resetting to immediately 0 would make some troubles with your project. I did it by mistake, but this is much more useful for my script
