Constructor Detail

Vehicle

public Vehicle(int id,
               int position,
               float maxVelocity,
               float brakeProb,
               float trackLength)

Constructs a new vehicle.

Parameters:

id - a number to index the vehicle

position - current position of the vehicle on the track

maxVelocity - maximum velocity of the vehicle

brakeProb - probability of the vehicle to brake without reason

trackLength - length of the track the vehicle is placed on

Method Detail

getPosition

public float getPosition()

Getter for position

Returns:

position

getCurVelocity

public float getCurVelocity()

Getter for curVelocity

Returns:

curVelocity

getMaxVelocity

public float getMaxVelocity()

Getter for maxVelocity

Returns:

maxVelocity

setBrakeProb

public void setBrakeProb(float brakeProb)

Setter for brakeProb

setMaxVelocity

public void setMaxVelocity(float maxVelocity)

Setter for maxVelocity

updateVelocity

public void updateVelocity(float distanceForerunner)

Calculates the new velocity of the vehicle based on the following rules:

1. Increase by one if the vehicle is slower than it's maximum speed
2. Random brake by one
3. Break if the distance to the forerunner is less than it's speed

Parameters:

distanceForerunner - distance to the forerunner of the vehicle

timeElapse

public void timeElapse()

Updates the position of the vehicle according to it's previously calculated speed.
