monobehaviour class (javascript)

Questions & Answers

so far i was using components, i want to try with classes now. i made a simple class, but it seems that i do not know how to use it. here is the example:

class test extends MonoBehaviour{

    var show : boolean=false;

    function OnGUI(){

        if(show){       
            GUI.Label(Rect(200,200,200,200),"Label");       
        }
        if(Input.GetMouseButtonDown(0)){            
            show=!show;     
        }   
    }
}

so pressing the button, label should show, but when i try to instantiate the object of this class in other script i do not get the desirable result. i tried to do something like this: `var test : test=new test();` //this does not work on monobehaviours then i tried this: `var test : test;`// this does not automatically start the OnGUI function in the class i even tried this `test.OnGUI` in other scripts OnGUI, that clearluy did not work.

so can somebody explain how to use the monobehaviour class and all basic things related to it. thanks!!

Monobehaviour classes need to be attached to a GameObject to work - only then will it's member functions (Awake, Start, Update, OnGUI etc.) be called.

So you either need to create a GameObject (probably an empty, if all it does is contain gui scripts) and attach your script in the editor, or if you want to create it later on, make a prefab containing this script, and instantiate it from code.

Another alternative, which may fit more closely to what your trying to achieve, is to add your test class as a component to an existing object:

var testclass : test;
testclass = gameObject.AddComponent("test");
