Detailed Description

Simulates a raycast vehicle which casts a ray per wheel at the ground as a cheap replacement for complex suspension simulation.

The suspension can be tuned in various ways. It is possible to add a (probably) arbitrary number of wheels.

BulletVehicle::BulletVehicle ( BulletWorld *  world,
BulletRigidBodyNode *  chassis 
)

Creates a new BulletVehicle instance in the given world and with a chassis node.

void BulletVehicle::apply_engine_force ( PN_stdfloat  force,
int  idx 
)

Applies force at the wheel with index idx for acceleration.

Definition at line 146 of file bulletVehicle.cxx.

References get_num_wheels().

BulletWheel BulletVehicle::create_wheel ( )

Factory method for creating wheels for this vehicle instance.

Definition at line 182 of file bulletVehicle.cxx.

BulletRigidBodyNode * BulletVehicle::get_chassis ( )

Returns the chassis of this vehicle.

The chassis is a rigid body node.

Definition at line 84 of file bulletVehicle.cxx.

Referenced by BulletWorld::remove_vehicle().

PN_stdfloat BulletVehicle::get_current_speed_km_hour ( ) const

Returns the current speed in kilometers per hour.

Convert to miles using: km/h * 0.62 = mph

Definition at line 97 of file bulletVehicle.cxx.

LVector3 BulletVehicle::get_forward_vector ( ) const

Returns the forward vector representing the car's actual direction of movement.

The forward vetcor is given in global coordinates.

Definition at line 72 of file bulletVehicle.cxx.

int BulletVehicle::get_num_wheels ( ) const [inline]

Returns the number of wheels this vehicle has.

Definition at line 58 of file bulletVehicle.I.

Referenced by apply_engine_force(), get_steering_value(), get_wheel(), set_brake(), and set_steering_value().

PN_stdfloat BulletVehicle::get_steering_value ( int  idx) const

Returns the steering angle of the wheel with index idx in degrees.

Definition at line 120 of file bulletVehicle.cxx.

References get_num_wheels().

BulletVehicleTuning & BulletVehicle::get_tuning ( ) [inline]

Returns a reference to the BulletVehicleTuning object of this vehicle which offers various vehicle-global tuning options.

Make sure to configure this before adding wheels!

Definition at line 47 of file bulletVehicle.I.

BulletWheel BulletVehicle::get_wheel ( int  idx) const

Returns the BulletWheel with index idx.

Causes an AssertionError if idx is equal or larger than the number of wheels.

Definition at line 226 of file bulletVehicle.cxx.

References BulletWheel::empty(), and get_num_wheels().

static void BulletVehicle::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from TypedReferenceCount.

Definition at line 112 of file bulletVehicle.h.

References TypedReferenceCount::init_type().

void BulletVehicle::reset_suspension ( )

Resets the vehicle's suspension.

Definition at line 108 of file bulletVehicle.cxx.

void BulletVehicle::set_brake ( PN_stdfloat  brake,
int  idx 
)

Applies braking force to the wheel with index idx.

Definition at line 158 of file bulletVehicle.cxx.

References get_num_wheels().

void BulletVehicle::set_coordinate_system ( BulletUpAxis  up)

Specifies which axis is "up".

Nessecary for the vehicle's suspension to work properly!

Definition at line 46 of file bulletVehicle.cxx.

void BulletVehicle::set_steering_value ( PN_stdfloat  steering,
int  idx 
)

Sets the steering value (in degrees) of the wheel with index idx.
