I already provide a solution for this kind of thing but it is a ton more advanced and likely a little out of your comfort zone currently. If you want to learn blueprints then this is a good starting project as it is fairly simple and a good initiation to basic blueprint nodes that are commonly used.
Also as I said, most of it is already in his template he was kind enough to provide for you.
Edit Actually I checked Runebergs VR plugin and it has a flat value gravity option on it, you could use that as well since it is on the marketplace it is easy to install and use. It is kind of an in between from teleport only pawns to full characters, likely suited to your use.
