Overridden virtual functions cannot be used as Animation events



To Reproduce:

1.Write an overridden virtual function just like Event4() in Arrow.cs and ArrowBase.cs, in the attached project.

2. Create a new event on the ScaleUp animation, which is being played on the Arrow object, notice that 'Event4' which overrides a virtual function cannot be used as an event handler (Event1 & 2 from the same script work fine).

3. It's possible to workaround this by first assigning the function in the event and then changing in to an overridden virtual function (as Event3 in this case) and it seems to work fine.

    Ok I was wrong. Does not work because the base type method will be called instead of the derived one.

    Overriding did not work for me (in UI Events). Even the overriden methods wont show up.
    I found a workaround to have a non virtual method in the base class that calls the virtual method.
    Its just som kind of wrapper and you can forget about it in the derived types.

    I'll be trying this workaround because it's REALLY annoying to break all the OO we had so much work on doing T_T

    We just rewrite the functions in the derived classes and reuse the base functions.

    Base class:
    public virtual void DoAnimationEvent()

    Derived class:
    public override void DoAnimationEvent()

    How long can we wait for such a simple issue?

    Another workaround is to use another function that can be selected, then modify the anim file in a text editor to use the correct function (assuming you serialize assets as text).
