Hi,

I want my script make a selection of all child of my object in editor scene. Well,tried such code:

@CustomEditor (SolidDiscExample)
class DrawSolidDisc extends Editor {
	
	var positions : Vector3[];
	var aChild:GameObject;
	
    function OnSceneGUI () {
		Handles.color = Color(1,0,0,0.1);
        Handles.DrawSolidDisc(target.transform.position, Vector3.up, target.areaOfEffect);
        Handles.color = Color.cyan;
        target.areaOfEffect = 
        Handles.ScaleValueHandle(target.areaOfEffect,
                            target.transform.position + Vector3(target.areaOfEffect,0,0),
                            Quaternion.identity,
                            2,
                            Handles.CylinderCap,
                            2);
							
		if(target.transform.childCount>0){
			for(var i = 0;i<=1; i++){
			aChild =  target.transform.Find(target.transform.name + i);
			
			Handles.color = Color(1,0,0,0.1);
			Handles.DrawSolidDisc(aChild.transform.position, Vector3.up, aChild.areaOfEffect);
			Handles.color = Color.cyan;
			aChild.areaOfEffect = 
			Handles.ScaleValueHandle(aChild.areaOfEffect,
										aChild.transform.position + Vector3(aChild.areaOfEffect,0,0),
										Quaternion.identity,
										2,
										Handles.CylinderCap,    										2);
			}
			
			
		}
    }
}

But I believe that there no reference to child at all or something because have exception:
NullReferenceException

and

InvalidCastException: Cannot cast from source type to destination type.

Thanks, Luize. Here is answer:

for(var aChild : Transform in target.transform)
{
    Debug.Log(aChild.name);
}
