Collecting data from children

(using C#)
So I have a class IcarusBaseObject with a variable uint Health;

How would I retrieve the Health of all children who have an IcarusBaseObject?

 

Code (csharp):

1. foreach (IcarusBaseObject ibo in GetComponentsInChildren(typeof(IcarusBaseObject))) {
2.     Debug.Log(ibo.Health);
3. }

Note that it'll also print the Health of object the script this is attached to, if it has IcarusBaseObject. You can ignore that by something like...

if (ibo.gameObject != gameObject)
...

Cheers,

First create a property for your health in the IcarusBaseObject script:

Code (csharp):

1.  
2. private uint health;
3.  
4. public uint Health
5. {
6.    get { return health; }
7.    set { health = value; } //if you also need a set
8. }
9.  

Now get and reference to all gameObjects with a IcarusBaseObject script:

Code (csharp):

1.  
2. Component[] icarusBaseArray;
3. icarusBaseArray = gameObject.GetComponentsInChildren( typeof(IcarusBaseObject) ) as Component[];
4.  

Then run through the array in the parent:

Code (csharp):

1.  
2. foreach ( IcarusBaseObject icarusBase in icarusBaseArray )
3. {
4.    uint retrievedHealth = icarusBase.Health;
5.    // do something with retrievedHealth...
6. }
7.  

EDIT: Harrr... Jonathan was faster...

 

ahh, I see what I did wrong. I needed to do typeof(IcarusBaseObject)

By the way, ALL THESE REFERENCES TO ICARUS ARE JUST COINCIDENCES I SWEAR :wink:

 

My solution. Should give me what I want. Recursion is scary.

Code (csharp):

1.  
2. public uint getTotalHealth()
3.     {
4.         uint tHealth = getHealth();
5.         Component[] AllHealths = GetComponentsInChildren(typeof(IcarusBaseObject));
6.         foreach(IcarusBaseObject x in AllHealths)
7.         {
8.             // don't include ourselves, or we infinitely recurse
9.             if(x.gameObject != gameObject)
10.                 tHealth+=x.getTotalHealth();
11.         }
12.         return tHealth;
13.     }
14.
