#3

my flax version is 1.6;

#4

I solve it by GameplayGlobals.in AnimEvent ,it will changed.i make it flag to trigger states.

#5

is there other ways?

You are trying to access an element of a cleared list. The list will have no elements because it is cleared. If you want the 0 element of the list to exist after you clear it, you will need to .Add(Guid.Empty).

#7

Not sure exactly what you are trying to do… but you can override the OnEvent function to get a reference to the AnimatedModel actor and then access any scripts or other actors from that actor. For future reference, it would be good to break this question out into another forum post so that way it is easier to track and find for others.
