Struct PendulumTrap 

pub struct PendulumTrap {
    pub rope: RopeChain,
    pub damage: f32,
    pub weight_radius: f32,
    pub weight_mass: f32,
}

A pendulum trap using a rope chain with a fixed top point. Swings under gravity and damages entities on contact with the weighted end.

Fields

rope: RopeChain

damage: f32

Damage dealt on contact.

weight_radius: f32

Radius of the weight at the end for collision detection.

weight_mass: f32

Mass multiplier for the last point (the weight).

Implementations

impl PendulumTrap

pub fn new( pivot: Vec3, length: f32, segments: usize, damage: f32, weight_radius: f32, ) -> Self

Create a pendulum hanging from pivot with the given length and segments. The weight hangs at the bottom.

pub fn push(&mut self, force: Vec3)

Give the pendulum an initial push.

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

Step the pendulum simulation.

pub fn weight_position(&self) -> Vec3

Get the weight (endpoint) position for collision checks.

pub fn check_collision(&self, point: Vec3) -> bool

Check if a point is within the weight’s damage radius.

pub fn get_points(&self) -> Vec<Vec3>
