- What's the best way to get the player's (or a character's in general) actual velocity in game? I wrote a custom function to get it based on current and past pos() per frame but I'm sure there's a better way to do it and I wouldn't want to do this every single time I need velocity values.

- What's the best way to access the components of an object? i.e. collision primitive.

1. You can use Actor data to get it, Actor.vel(). Character itself doesn't have velocity, but its Actor does.
2. Just as class variables? (or I didn't understand the question)

1. Getting the vel from the actor worked really well! Much better than my own implementation using the pos(). Thanks!
2. Just interested in scaling down the capsule collision on crouch.

Look at Controller class, it has the scaling for crouching.
(Game::Chr uses it)

Found it, thanks a lot!
