#how can I make a animation of a monster that do something and start chasing you

Place an animator… then um you kinda animate it? move the and save them as frames, each frame will be a different motion eventually leading up to a full step forward

Just as a tip!
When doing animation studying the movement of your object will be very important
For example you want someone walking/chasing, looking at other animations or looking for GIF's or videos will help give you reference for each frame.
Use ease an easefast to smooth out your animation! Using the smooth toggle will hurt your animation rather then benefit it!

Seriously tho, skill

Not saying you can't of course!
