Hey guys i’m stucking at this point,So basically boss is not jumping directly to my character and i dont know why even i changed arc parameters to 99 and it is still not working ,is there anybody can help me about this?
Hey @QWER9983! Welcome to the forums!
So my first question is:
I see you are using a montage. Are you also using root motion for this attack animation? Or is the actor actually staying in place?
It may be better to forego the arc if you are using root motion, and using “Set character location” on a lerp. OR creating a temporary spline for the boss to follow as it jumps. Because what you’re adding with the arc is a physics-based impulse- if physics are not enabled on the character, or they have high mass, they will be unaffected. The node you are using is for projectiles, like an arrow shot from a bow, or a mortar or cannon shot. 
see your collisions and make sure you are getting the position from the player capsule and not from some other hitbox
