How do i make a child object follow animation?

I’m a beginner so I apologize in advance for anything that is hard to understand. I am trying to get a child object (the character’s arm) to follow the animation of the character. My problem is that the idle animation moves up and down but the arm does not move at all. I have a video linked below to show the problem.

How is your character set up, hierarchy-wise?

This is my player

Can you share a higher resolution screenshot? I can’t read that, sorry!~

Is this any better?

Ah ok, so your player’s animation is driven by a spritesheet, not actual Transform animation. That means there’s not actually any transform positions changing in your animation, so there’s nothing for the arm to “follow”. I’m not sure what the best technique is here. The arm/gun might need to have their own animations which match the player’s animation?

Awesome Thanks!
