How do i select a random animation for an NPC?

I’m currently working on a boss fight which has a couple of different moves. Let’s say: smash, sweep & strike.

How could i set up a system that selects a random attack animation based on a timer (or is there a better way)?

Been experimenting a bit, i’ll let you know how things turn out.
Help is still much needed and wanted.

Update! It’s working. Now i just need to find out how to pause an animation.
