Return string to be accessed from other class

I have the function of displaytext in blue.cs. It should return a string of textApp. Then ocean.cs will access the string textApp and use it for display.
How do I modify this code? and how can i access it from ocean.cs

blue.cs

Code (CSharp):

1. void displaytext()
2.     {
3.         for(int i = players.Count - 1; i >= 0; i--)
4.         {
5.             if(players[i].name == "miao")
6.             {
7.                 textApp= textApp + players[i].GetComponent<miao>().type+" " + players[i].GetComponent<miao>().colour+" " + players[i].GetComponent<miao>().weight;
8.                 textApp= textApp+ "\n";
9.             }
10.         }
11. }

 

there are several ways to achieve this, one would be to make the method static, that way you can access it from every class, but it might change it's behaviour, and is not the way you want it to work.
Another way would be to simply add a public property of your blue script inside the ocean script file, attach the blue script to that property and you can simply access the variable if it's public (if nothing stands in front of your void, it's default is private, so you have to add the "public" word in front of it)

 

Is the second way something like this?

Code (CSharp):

1. myObject.GetComponent<MyScript>().MyFunction();

 

That would be one way, yes. If you can, you should prefer setting up those scripts manually in the Unity editor/inspector. (e.g. http://forum.unity3d.com/threads/ho...ment-in-the-second-class.396861/#post-2590418 )
