N00b C# question getting int from 1 script to another

not sure if im even going in the right direction here i was creating a simple script with a list of base stats eg health mana etc with value, then i wanted my ui script to be able to access these values and pass them in my gui for now so the base stat script ive got

Code (CSharp):

1. public class base_stats{
2.  
3.     public static int starthp;
4.     public base_stats()
5.     {
6. starthp = 44;    // Starting health
7.     }
8. }
9.  

then my ui script ive got

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class ui : MonoBehaviour{
4.     void Start () {}
5.     void Update () {}
6.  
7.     void OnGUI(){
8.     GUI.Box(new Rect(1,1, 50, 50), (base_stats.starthp));
9. }
10. }

i know ive got either the layout/format wrong here but im trying to learn so please no nasty comments i thought at first this was going to work, i declared the starthp variable as public then i gave it an actual value, then from the other script i thought i could just reference it in the way above, however i get 2 errors

cant convert int to string,
and an invalid argument in the GUI.Box line of code, which usually means ive got the syntax wrong, any help on this will be appreciated. i am trying to learn so any simple explanations for this is much appreciated

 

Try this:
base_stats.starthp.ToString()

And you might need to call the base_stats() function

 

mmm hiya thanks for the speedy response, yeah i added To.String() and it did clear the error however it returns the value 0 instead of 44 which is in the base_stats,

is this because im passing that value as a string when it should be an int? again im really new to this so im not sure im on the right page sorry if that seems a little dim

thanks again

 

Try this

Code (CSharp):

1. public class base_stats{
2.  
3.     public static int starthp = 44;
4.  
5. }
6.  

Then in the GUI.Box use base_stats.starthp.ToString(); or System.Convert.ToString(base_stats.starthp);

Just a heads up, static variables are not reset upon changing scenes etc, so if you want to reset them you would have to make your own function

Code (CSharp):

1.  
2. public static void ResetStats(){
3.  starthp = 44;
4. }
5.  

 

Code (CSharp):

1. public class base_stats{
2.  
3.  
4.     public static int starthp;
5.  
6.     public base_stats()
7.  
8.     {
9.  
10. starthp = 44;    // Starting health
11.  
12.     }
13.  
14. }
15.  
16.  

What is static, anyway? Static means that there's no copies of this, there's only one of these. Your base stats class isn't static, though. It has to be copied into a new instance. Where you've said starthp = 44 is in the code that runs when a new instance of base stats is created. Since you aren't creating a new instance of base stats, that code never runs!

You should instead create a static constructor.

Instead of public base_stats(), type static base_stats() and that code will run when your program starts.

 

thanks both you literally

System.Convert.ToString(base_stats.starthp);

did the trick perfectly
