Share variables among scripts of the same object

Questions & Answers
1

I have a normal game object that represents a lamp, and for it i have a script responsible for turning on/off, and then another script responsible for glowing or unglowing the lamp when it is on or off respectively.

The thing is, inside my turn on/off script I have a status variable (a boolean) that tells its current status (on/off), and I want the other script to have access to it. But how can I do such thing? Scripts can’t handle variables of other scripts, even if they’re attached to the same object so far i know.

Thanks!

//some script

public class Toggle : MonoBehaviour
{
    ...
    public bool IsEnabled
    {
        return ...
    }
}

//other script on same gameobject

public class Glower : MonoBehaviour
{
    ...
    void GlowEffectApply()
    {
        bool lightEnabled = GetComponent().IsEnabled
    }
}

Here’s a UnityScript example:

// Toggle script
// Toggle.js

var state = false;

// [...]

In your other script just do this if you want to read the state variable:

if (GetComponent(Toggle).state)

If you need to access the variable a lot, or you need other things from that component, save a reference to it. GetComponent have to search for the component on the gameobject eachtime you call it. It’s better to setup the references in Start and use the reference directly:

// another script on the same gameobject
private var myToggleScript : Toggle;

function Start()
{
    myToggleScript = GetComponent(Toggle);
}

function Update()
{
    if (myToggleScript.state)
    {
        // [...]
    }
}

Note: I’m posting this as an answer because it is quite an answer to a question here and because I need the Code section or else the linebreaks will get messy.

I’ve get it, if I define a monobehaviour class inside a .js Unity will not make that conversion. Meaning that in file (1) I can put the OnOff class and then extend it in file (2) and it will behave correctly!
So in Unity having this in a “Example.js”:
------Code------

function start() {...}
function update() {...]

is EXACTLY the same as
having this in a “Example.js”:
------Code------

public class Example extends MonoBehaviour {
function start() {...}
function update() {...]
}

And the same goes for C#. This is awesome, now my code will get pretty! :smiley:

Thank you guys!
