Variable from other class always returns 0
I'm trying to call an int from another class and I've tried everything, from instancing to creating a new instance using the = new.... Considering this is scripting and not straight up class-making i guess it's different because it attaches to an object.
Here's my problem, I have a really nice stat system set up, alright, not really nice, but for just starting out with unity I like it. Either way, I'm going to send you the basics of the code and see if you guys can help
StatHandler.cs
public class StatHandler : MonoBehaviour {
public int stamina, strength, agility, dexterity, wisdom;
public int baseHealth, baseMana;
public int statPoints;
public bool showingStatGUI;
#region start
void Start() {
//TODO Class Based Stats
stamina = 10;
strength = 10;
agility = 10;
dexterity = 10;
wisdom = 10;
baseHealth = stamina * 10;
baseMana = wisdom * 10;
statPoints = 100;
showingStatGUI = false;
}
#endregion
#region getters
public int Stamina {
get { return stamina; }
set { stamina = value; }
}
I tried using a getter this time to return the value and still have no luck, please remember that on the StatHandler itself the variables do have values, which I can edit with the gui I created.
Here's the other part
HealthManager.cs
public int stamina;
public float healthBarLength;
// Use this for initialization
void Start () {
StatHandler sh = new StatHandler();
healthBarLength = Screen.width / 2;
stamina = sh.Stamina;
}
Please note, the above was just an attempt using the setter/getters, it tossed a compiler error without creating a new StatHandler, this is really irritating and my only problem with creating many scripts.
On a side note, after glimpsing at your profile:

Yes, thanks. I noticed that when using stack-overflow today.
Since you are inheriting from MonoBehavior, you can not use new,
so "StatHandler sh = new StatHandler();" is not an option.
By inheriting from MonoBehavior, you defined a unity Component for unity.
You have the option of either instantiate your class as part of the prefab object to which it is attached to: http://docs.unity3d.com/Documentation/ScriptReference/Object.Instantiate.html
Or add the component to an existing or newly created GameObject: http://docs.unity3d.com/Documentation/ScriptReference/GameObject.AddComponent.html
(Newly create a GameObject and add component: http://docs.unity3d.com/Documentation/ScriptReference/GameObject.GameObject.html)
You sir, have saved my day. I've only been using Unity for around a week now and never really thought of it this way... I'm going to try my luck doing this and I'll get back to you. Thumbs up for now.
So, would I have to create my entire player GameObject through a script? perhaps I'm not understanding this correctly. Can I create a script that adds components and attatch it to a GameObject I already have created?
I figured it out, although it's still returning a value of 0 for any integer i try to full from StatHandler.
Glad to had helped buddy!
$$anonymous$$ust likely, you would create a prefab - A game object with components already attached and set and any number of root game objects (themselves possibly parents of other game objects) - all of which are saved in the project level and can be referenced to the managing GameObject: http://docs.unity3d.com/Documentation/$$anonymous$$anual/Prefabs.html
You can also create a script that adds components and attach it to a game object you already created.
Well, I do have one problem that's really confusing me. Is there a way I could message you? I'm still having trouble retrieving the integer value, it's hitting 0. I wouldn't $$anonymous$$d sending you my scripts if you could point me in the right direction, I don't know what I'm doing wrong, but I'd love to find out. I've been googling for hours.
