SmartButtonEditor.cs for Unity3D

//We will use this variable, the selected enum in the smart button, not only to do different things in runtime, but also to show different inputs in the editor

//Same with the scenes
case SmartButton.Usage.SceneLoader:

//Adding a label

//Create a Game Object input. The user can drop game objects here, and we store them in OurPanel variable

//Same with the go to panel

//Good things about customizing inspector views. We can add some comments
EditorGUILayout.LabelField("If Go to Panel is null, it will only hide Our Parent Panel");
case SmartButton.Usage.IAPPurchase:
//Simple text field for the item id we want to purchase
smartButton.Value = EditorGUILayout.TextField("Item Id",smartButton.Value);
//Show nothing, just want to exit game
case SmartButton.Usage.Exit:
//Here we will get a monobehaviour reference, and a string to now what coroutine to call
case SmartButton.Usage.CoroutineTrigger:

//Just getting the Monobehaviour reference from our object input field
smartButton.ComponentToUse = (MonoBehaviour)EditorGUILayout.ObjectField(smartButton.ComponentToUse,typeof(MonoBehaviour),true);
//And the name of the coroutine
smartButton.Value = EditorGUILayout.TextField("Coroutine Name",smartButton.Value);
//IF something has changed, we let unity know, so it makes us save the scene, and therefore, the smart button values will be saved
