Function avian3d::collision::contact_query::time_of_impact

pub fn time_of_impact(
    collider1: &Collider,
    position1: impl Into<Position>,
    rotation1: impl Into<Rotation>,
    velocity1: impl Into<LinearVelocity>,
    collider2: &Collider,
    position2: impl Into<Position>,
    rotation2: impl Into<Rotation>,
    velocity2: impl Into<LinearVelocity>,
    max_time_of_impact: Scalar
) -> Result<Option<TimeOfImpact>, UnsupportedShape>

Computes when two moving Colliders hit each other for the first time.

Returns Ok(None) if the time of impact is greater than max_time_of_impact and Err(UnsupportedShape) if either of the collider shapes is not supported.

Example

use avian3d::prelude::{contact_query::time_of_impact, *};
use bevy::prelude::*;

let collider1 = Collider::sphere(0.5);
let collider2 = Collider::cuboid(1.0, 1.0, 1.0);

let result = time_of_impact(
    &collider1,        // Collider 1
    Vec3::NEG_X * 5.0, // Position 1
    Quat::default(),   // Rotation 1
    Vec3::X,           // Linear velocity 1
    &collider2,        // Collider 2
    Vec3::X * 5.0,     // Position 2
    Quat::default(),   // Rotation 2
    Vec3::NEG_X,       // Linear velocity 2
    100.0,             // Maximum time of impact
)
.expect("Unsupported collider shape");

assert_eq!(result.unwrap().time_of_impact, 4.5);
