constant player movement

[Predator106]

indeed, as usual you're absolutely correct

So now i got horizontal movement to work properly...but if I make the player jump by providing an impulse vertically, the player does jump but there is no air control.

I don't see why that wouldn't work. So the movement only works when his feet are on the ground. But the friction with the air should be 0 so..weird.

So surface velocity makes the physics think the surface of shape is moving separately from it's rigid body. Think like a conveyor belt. It doesn't change shape, but it's surface moves. For your player, the overall player shape doesn't change, but the feet would be moving. Same idea.

Now, when the player is in the air, it's not in contact with anything and therefor no friction force to accelerated (or decelerate) the player's movement. If you look at the second link I posted earlier, I handle air control separately. You could calculate a force for it, but since you are already in the velocity integration callback it's easier to just integrate it yourself and apply a small change to the velocity.
