I am currently working on a 2d racegame where I am using physics to move a vehicle. On my form I would like to add a label containing the speed on the vehicle.
My physics knowledge is a little rusty, haven't done anything with it for a while, so I am asking the following question. Which of the calculations in my code represent the total velocity of my vehicle?
My relevant code:
//our simulation object
class RigidBody
{
//linear properties
private Vector m_position = new Vector();
private Vector m_velocity = new Vector();
private Vector m_forces = new Vector();
private float m_mass;
//angular properties
private float m_angle;
private float m_angularVelocity;
private float m_torque;
private float m_inertia;
public void Update(float timeStep)
{
//integrate physics
//linear
Vector acceleration = m_forces / m_mass;
m_velocity += acceleration * timeStep;
m_position += m_velocity * timeStep;
m_forces = new Vector(0,0); //clear forces
//angular
float angAcc = m_torque / m_inertia;
m_angularVelocity += angAcc * timeStep;
m_angle += m_angularVelocity * timeStep;
m_torque = 0; //clear torque
}
}
Hopefully someone will be able to help.
