A character controller for kinematic bodies.

Fields

up: UnitVector<f32>

The direction that goes “up”. Used to determine where the floor is, and the floor’s angle.

offset: CharacterLength

A small gap to preserve between the character and its surroundings.

This value should not be too large to avoid visual artifacts, but shouldn’t be too small (must not be zero) to improve numerical stability of the character controller.

slide: bool

Should the character try to slide against the floor if it hits it?

autostep: Option<CharacterAutostep>

Should the character automatically step over small obstacles? (disabled by default)

Note that autostepping is currently a very computationally expensive feature, so it is disabled by default.

max_slope_climb_angle: f32

The maximum angle (radians) between the floor’s normal and the up vector that the character is able to climb.

min_slope_slide_angle: f32

The minimum angle (radians) between the floor’s normal and the up vector before the character starts to slide down automatically.

snap_to_ground: Option<CharacterLength>

Should the character be automatically snapped to the ground if the distance between the ground and its feed are smaller than the specified threshold?

normal_nudge_factor: f32

Increase this number if your character appears to get stuck when sliding against surfaces.

This is a small distance applied to the movement toward the contact normals of shapes hit by the character controller. This helps shape-casting not getting stuck in an always-penetrating state during the sliding calculation.

This value should remain fairly small since it can introduce artificial “bumps” when sliding along a flat surface.

Implementations

impl KinematicCharacterController

pub fn move_shape( &self, dt: f32, bodies: &RigidBodySet, colliders: &ColliderSet, queries: &QueryPipeline, character_shape: &dyn Shape, character_pos: &Isometry<f32>, desired_translation: Vector<f32>, filter: QueryFilter<'_>, events: impl FnMut(CharacterCollision), ) -> EffectiveCharacterMovement

Computes the possible movement for a shape.

pub fn solve_character_collision_impulses<'a>( &self, dt: f32, bodies: &mut RigidBodySet, colliders: &ColliderSet, queries: &QueryPipeline, character_shape: &dyn Shape, character_mass: f32, collisions: impl IntoIterator<Item = &'a CharacterCollision>, filter: QueryFilter<'_>, )

For the given collisions between a character and its environment, this method will apply impulses to the rigid-bodies surrounding the character shape at the time of the collisions. Note that the impulse calculation is only approximate as it is not based on a global constraints resolution scheme.
