OnDrawGizmos for parent and child class

Questions & Answers
1

Hey all –

So I have a parent class which draws to the editor window on OnDrawGizmos(), which is great. However, I have a child of that parent class which wants to draw the same stuff as the parent on OnDrawGizmos(), plus a bit more info. So, I want to do something like

class Child : Base
{
   void OnDrawGizmos()
   {
      //do stuff
      base.OnDrawGizmos();
   }
}

but this doesn’t work! Visual Studio warns me that ‘Parent.OnDrawGizmos() is inaccessible due to its protection level’ and Unity gives me an internal compiler error, “System.InvalidOperationException: Method ‘Child.OnDrawGizmos’ does not have a method body” (which it clearly has). So… what’s happening here?

parent class should be…

class ParentClass : MonoBehaviour
{

    public virtual void OnDrawGizmos()
    {
        //parent gizmo rendering
    }
}

the child should be

public class ChildClass : ParentClass
{
    public override void OnDrawGizmos()
    {
        base.OnDrawGizmos();
        //child gizmo rendering
    }
}
