I think there's a regression in rapier 0.21. Getting this error for the first time now in an otherwise unchanged codebase (other than upgrading to Bevy 0.10) |
|
Just tried this again to see if anything has changed with the new versions and the example I provided still consistently panics, hitting this Here's an updated example: [dependencies]
bevy = "0.10.0"
bevy_rapier3d = "0.21.0"use bevy::prelude::*;
use bevy_rapier3d::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugin(RapierPhysicsPlugin::<NoUserData>::default())
.add_startup_system(setup)
.run();
}
fn setup(mut commands: Commands) {
commands.spawn((
TransformBundle::from_transform(
Transform::from_xyz(0.0, 0.0, 20.0)
// Commenting out this line it no longer panics
.with_scale(Vec3::splat(2.0)),
),
// If you use a different collider that isn't a bevy mesh here it no longer panics
Collider::from_bevy_mesh(
&Mesh::from(shape::Cube { size: 3.0 }),
&ComputedColliderShape::TriMesh,
)
.unwrap(),
RigidBody::Fixed,
));
commands.spawn((
Collider::ball(1.0),
RigidBody::Dynamic,
// Commenting out this line it no longer panics
// Ccd::enabled(),
Velocity::linear(Vec3::Z * 10000.0),
));

As for me, my code magically works now. Strange 🤷♂️ |
|
Also ran into this same issue. |
|
It only happens when i use ComputedColliderShape::TriMesh, if i switch to ComputedColliderShape::ConvexDecomposition(VHACDParameters::default()), it stops |
|
Have the same issue with CCD and TriMesh (and WASM): bevy = "0.13.0" |

Updated example for bevy 0.13 and bevy_rapier3d 0.26 no longer panics but returns the error: main.rsuse bevy::{math::vec3, prelude::*};
use bevy_rapier3d::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugins(RapierPhysicsPlugin::<NoUserData>::default())
.add_systems(Startup, setup)
.run();
}
fn setup(mut commands: Commands) {
commands.spawn((
TransformBundle::from_transform(
Transform::from_xyz(0.0, 0.0, 20.0)
// Commenting out this line it no longer panics
.with_scale(Vec3::splat(2.0)),
),
// If you use a different collider that isn't a bevy mesh here it no longer panics
Collider::from_bevy_mesh(
&Mesh::from(Cuboid {
half_size: vec3(1.5, 1.5, 1.5),
}),
&ComputedColliderShape::TriMesh,
)
.unwrap(),
RigidBody::Fixed,
));
commands.spawn((
Collider::ball(1.0),
RigidBody::Dynamic,
// Commenting out this line it no longer panics
Ccd::enabled(),
Velocity::linear(Vec3::Z * 10000.0),
));

Description
I'm getting a panic when two objects collide if one has a collider created using
from_bevy_meshand the entity has a scaled transform and the other object has ccd enabled.Click for full traceback
My use case is I have an asteroid field that has randomly placed asteroids with random scales. I have a custom collider mesh for the asteroids and I want my bullets that shoot the asteroids to use ccd so they don't go through the asteroids.
System
Windows 11
Bevy 0.8
bevy_rapier3d 0.16 (also main branch)
Minimal reproduction
This code demonstrates the error, it creates a fixed rigid body using a bevy mesh as a collider and a transform scaled to 2X, then creates a dynamic rigid body with ccd enabled and sends it at it with a high velocity.
