Struct Surface 

pub struct Surface {
    pub friction: f32,
    pub climbable: bool,
    pub belt: f32,
    pub bounce: f32,
}

The kind of a surface. Each field’s default leaves the tuning’s feel as it is.

Fields

friction: f32

Scales running’s acceleration, braking and turning on this ground: 1.0 as tuned, below for ice (0.1 slides a long way), above for sticky ground.

climbable: bool

Whether the character may grab and climb this wall. Wall slides and wall jumps still work on a wall that isn’t climbable.

belt: f32

A conveyor belt: carries what stands on it sideways at this speed, units/s (positive right). A jump off it keeps the speed, as off moving ground.

bounce: f32

Bounciness: a landing faster than Surface::BOUNCE_MIN bounces back up at this share of its downward speed (0.0: none, 1.0: as fast as it came down).

Implementations

impl Surface

pub const DEFAULT: Surface

Plain ground: the tuning’s feel, climbable, still, not bouncy.

pub const BOUNCE_MIN: f32 = 40.0

The slowest landing (units/s down) a bouncy surface bounces back.
