Hey guys, thanks for the suggestions. Just to update, I did happen to use a timeline, but I did not use world location (however, this advise seems promising, I will try it out!). Instead, I used this:
It adds impulse over a timeline, which does affect the movement component (which, I would assume, if you have the animation set up correctly, the character can run during the velocity change), which is a plus. Good for my uses so far, and respects gravity too.
Cheers
