How to add a partical system to my animation

Do I have to use script to combine my punch animation with a vfx to give it more oomph or is there a way to doit without anyscript?

 

I think it depends on how your punch animation is made. If it's created and edited within Unity, then yes, you can simply activate the particle system as well. But if it's an imported animation, then you can't. But I believe you can still add animation events to an imported animation; so you could use one of these to trigger the particle effect. Or, you could add a StateMachineBehaviour to your animator controller, and trigger the vfx with that.
