Struct a1_vehicle::vehicle::Vehicle

pub struct Vehicle {
    pos: Vector2<f32>,
    vel: Vector2<f32>,
    accel: Vector2<f32>,
}

Fields

pos: Vector2<f32>

vel: Vector2<f32>

accel: Vector2<f32>

Implementations

impl Vehicle

const MAX_FORCE: f32

const MAX_VEL: f32

pub fn new(pos: [f32; 2], vel: [f32; 2]) -> Vehicle

pub fn integrate(&mut self, dt: f32)

Step a vehicle forward in time with an euler integrator.

Params

dt is the timestep used for integration. Behavior can become unstable for large dt or for large velocities and accelerations.

pub fn enforce_bounds(&mut self, bounds: &Bounds)

Enforce bounds, don’t let the vehicles escape the screen.

pub fn seek_vel(&mut self, target_vel: Vector2<f32>, secs_to_target: f32)

Seek a target velocity.

Params

• target_vel is the desired velocity, if not otherwise effected the vehicle will eventually reach the target velocity.
• secs_to_target is how many seconds (floating point) it should take for the vehicle to reach the target velocity.

pub fn apply_force(&mut self, force: Vector2<f32>)

Apply a force to a vehicle.

Forces are reset to zero after each integration.

pub fn draw(&self, batch: &mut Batch)

Draw the vehicle as a triangle to a single graphics layer.
