What is RoAction?
RoAction is a movement script that adds a more smooth walkspeed.
It also comes with its own character configuration!

WARNING This currently does not have mobile or console support. And it is designed for r15
Looks pretty smooth, i like it. will check it out later.
Very cool! What if you added deacceleration aswell 
Thanks, also I don’t think that it is possible due to how I made the script. But thanks for the feedback!
UPDATE!
I have now made it so then you build momentum properly by jumping, it will boost your speed temporarily because that is how momentum works!

I see that when you double jump, your character bounces on the ground after falling? Seems to be a bug.
I will look into it tomorrow. (If I remember to)
