Does the Unity Inspector support Inheritance?
Not to be confused with this related question, I know Unity does Inheritance but I'd like to leverage it in the Inspector.
I'd like to be able to switch the action to be performed on-the-fly using buttons in the GUI. So, I've got a class AbstractAction that inherits from MonoBehaviour which has a single abstract method DoAction. I've written a couple of scripts that inherit from AbstractAction and override the method, and I want to assign them to specific slots in the GUI using the inspector (similarly to how I assign the Texture2Ds for the buttons themselves).
public class MyGui : MonoBehaviour {
public Texture2D[] buttons;
public AbstractAction[] actions;
private int selectedAction;
void OnGUI() {
selectedAction = GUILayout.SelectionGrid(0, buttons, 2);
}
public void DoSelectedAction() {
actions[selectedAction].DoAction();
}
}
My problem is, the array is showing up fine in the Inspector (with elements "None (Abstract Action)"), but I cannot assign my subclasses of AbstractAction to them. Is there a way around this? I've tried using both an actual abstract parent, and a normal class with a virtual method.
Thanks in advance
I recall you need to make it serializable to make it show up there. But I'm not sure actually so posting it as comment/idea ins$$anonymous$$d of answer.
Turns out this is possible to do. My problem was that I was attempting to drop the script itself into the array in the Inspector. Instead, it was expecting a GameObject (or prefab) that has an AbstractAction script (or a script that inherits from it) attached.
Ultimately I created a prefab for each action that contains both the texture and the action script subclass, and therefore only need a single array to define them both in the GUI. Clean, functional and properly captures the relationship between the image and the action!
