Variable Documentation

◆ CHASSIS_MASS

const float physics::vehicle::car_data::CHASSIS_MASS = 1500.0f

Some default values for the car creation. Not for final game. Set up the chassis mass, dimensions, moment of inertia, and center of mass offset. The moment of inertia is just the moment of inertia of a cuboid but modified for easier steering. Center of mass offset is 0.65m above the base of the chassis and 0.25m towards the front.

◆ NUMBER_OF_WHEELS

const float physics::vehicle::car_data::NUMBER_OF_WHEELS = 4

◆ WHEEL_MASS

const float physics::vehicle::car_data::WHEEL_MASS = 20.0f

◆ WHEEL_MOI

const float physics::vehicle::car_data::WHEEL_MOI = 0.5f * WHEEL_MASS * WHEEL_RADIUS * WHEEL_RADIUS

◆ WHEEL_RADIUS

const float physics::vehicle::car_data::WHEEL_RADIUS = 0.5f

◆ WHEEL_WIDTH

const float physics::vehicle::car_data::WHEEL_WIDTH = 0.4f
