pub fn new_trigger(position: Vec3, shape: CollisionShape) -> Self

Create a trigger volume (no collision response, fires events).

pub fn pos2d(&self) -> Vec2

Position projected to 2D (XY plane).

pub fn vel2d(&self) -> Vec2

Velocity projected to 2D.

pub fn inv_mass(&self) -> f32

pub fn world_aabb(&self) -> AABB

Compute world-space AABB.

pub fn apply_force(&mut self, force: Vec2)

Apply a force (accumulated, applied during integration).

pub fn apply_torque(&mut self, torque: f32)

Apply a torque.

pub fn apply_impulse(&mut self, impulse: Vec2)

Apply an impulse at the center of mass.

pub fn apply_impulse_at(&mut self, impulse: Vec2, contact_offset: Vec2)

Apply an impulse at a contact point.
