Struct rapier2d::pipeline::ContactModificationContext [−][src]
Context given to custom contact modifiers to modify the contacts seen by the constraints solver.
Fields
rigid_body1: &'a RigidBody
The first collider involved in the potential collision.
rigid_body2: &'a RigidBody
The first collider involved in the potential collision.
collider_handle1: ColliderHandle
The first collider involved in the potential collision.
collider_handle2: ColliderHandle
The first collider involved in the potential collision.
collider1: &'a Collider
The first collider involved in the potential collision.
collider2: &'a Collider
The first collider involved in the potential collision.
manifold: &'a ContactManifold
The contact manifold.
solver_contacts: &'a mut Vec<SolverContact>
The solver contacts that can be modified.
normal: &'a mut Vector<Real>
The contact normal that can be modified.
user_data: &'a mut u32
User-defined data attached to the manifold.
Implementations
impl<'a> ContactModificationContext<'a>
[src]
pub fn update_as_oneway_platform(
&mut self,
allowed_local_n1: &Vector<Real>,
allowed_angle: Real
)
[src]
&mut self,
allowed_local_n1: &Vector<Real>,
allowed_angle: Real
)
Helper function to update self
to emulate a oneway-platform.
The “oneway” behavior will only allow contacts between two colliders
if the local contact normal of the first collider involved in the contact
is almost aligned with the provided allowed_local_n1
direction.
To make this method work properly it must be called as part of the
PhysicsHooks::modify_solver_contacts
method at each timestep, for each
contact manifold involving a one-way platform. The self.user_data
field
must not be modified from the outside of this method.
