BulletWheel¶

from acron.bullet import BulletWheel

class BulletWheel¶

Bases:

One wheel of a BulletVehicle. Instances should not be created directly but using the factory method BulletVehicle.create_wheel().

__init__()¶

property brake → float¶

Getter: Returns the amount of braking force currently applied.

Setter

property chassis_connection_point_cs → LPoint3¶: Returns/Sets the point where the wheel is connected to the chassis.

property clipped_inv_connection_point_cs → float¶

property delta_rotation → float¶

property engine_force → float¶

Getter: Returns the amount of accelleration force currently applied.
Setter: Defines how much force should be used to rotate the wheel.

property friction_slip → float¶

Getter: Returns how slippery the tyres are.
Setter: Sets the slipperyness of the tyre.

property front_wheel → bool¶: Determines/Sets if a/the wheel is steerable.

get_brake()¶: Returns the amount of braking force currently applied.

get_chassis_connection_point_cs()¶: Returns the point where the wheel is connected to the chassis.

get_clipped_inv_connection_point_cs()¶

get_delta_rotation()¶

get_engine_force()¶: Returns the amount of accelleration force currently applied.

get_friction_slip()¶: Returns how slippery the tyres are.

get_max_suspension_force()¶: Returns the maximum force (weight) the suspension can handle.

get_max_suspension_travel_cm()¶

get_node()¶: Returns the AcronNode which representates the visual appearance of this wheel, if such a representation has been set previously.

get_raycast_info()¶

get_roll_influence()¶: Returns the factor by which roll forces are scaled. See set_roll_influence().

get_rotation()¶

get_skid_info()¶

get_steering()¶: Returns the steering angle in degrees.

Warning

As of 1.11, this method uses degrees. Previous versions used radians.

get_suspension_relative_velocity()¶

get_suspension_rest_length()¶: Returns the length of the suspension when the vehicle is standing still.

get_suspension_stiffness()¶: Returns the stiffness of the suspension.

get_wheel_axle_cs()¶: Returns the normal vector of the wheel axle.

get_wheel_direction_cs()¶: Returns the wheel’s forward vector relative to the chassis.

get_wheel_radius()¶: Returns the wheel radius.

get_wheels_damping_compression()¶: Returns the damping applied to the compressing suspension.

get_wheels_damping_relaxation()¶: Returns the damping applied to the relaxing suspension.

get_wheels_suspension_force()¶

get_world_transform()¶

is_front_wheel()¶: Determines if a wheel is steerable.

property max_suspension_force → float¶: Returns/Sets the maximum force/suspension (weight)/force the suspension/wheel can handle.

property max_suspension_travel_cm → float¶: Getter Setter

Sets the maximum distance the suspension can travel out of the resting position in centimeters.

property node → AcronNode¶

Getter: Returns the AcronNode which representates the visual appearance of this wheel, if such a representation has been set previously.

property raycast_info → BulletWheelRaycastInfo¶

property roll_influence → float¶

Getter: Returns the factor by which roll forces are scaled. See set_roll_influence().
