Struct SwingArc 

pub struct SwingArc {
    pub start_angle: f32,
    pub end_angle: f32,
    pub duration: f32,
    pub elapsed: f32,
    pub origin: Vec3,
    pub radius: f32,
}

Describes a circular swing arc in 3D space (in the XZ plane centred at origin). The weapon tip traces from start_angle to end_angle over duration seconds at the given radius (== weapon length).

Fields

start_angle: f32

Starting angle in radians.

end_angle: f32

Ending angle in radians.

duration: f32

Total swing duration in seconds.

elapsed: f32

Elapsed time since swing began.

origin: Vec3

World-space origin of the swing (character pivot).

radius: f32

Radius of the arc (weapon length).

Implementations

impl SwingArc

pub fn new( start_angle: f32, end_angle: f32, duration: f32, origin: Vec3, radius: f32, ) -> Self

Create a new swing arc.

pub fn progress(&self) -> f32

Normalised progress of the swing [0, 1].

pub fn finished(&self) -> bool

Whether the swing has completed.

pub fn sample(&self, t: f32) -> Vec3

Position along the arc at normalised time t ([0,1]). The arc lies in the XZ plane relative to origin.

pub fn velocity_at(&self, t: f32) -> Vec3

Tangential velocity at normalised time t. The magnitude equals radius * angular_velocity.

pub fn tick(&mut self, dt: f32) -> bool

Advance the arc by dt seconds. Returns true while still active.

Trait Implementations

impl Clone for SwingArc

fn clone(&self) -> SwingArc

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SwingArc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
