Animation events & animator.speed

Hello,

I'm using animator.speed to control the direction and pause a sprite animation.

I also have an animation event setup for the final frame on the animation. The idea being that if the animation reaches the final frame, it should then run a function.

This works, however if I change the speed of the animation (say reverse it by setting animator.speed = 1f) the event from the final frame seems to trigger right away.

Should I not be modifying the speed directly? Is this known to mess with animation events?

Thanks for any insight!
