         - The <b>boost</b>, there are quite some parameters pertaining to boosting. The boost is a special move of the SpaceShip, where, for a limited amount of time, it can fly considerably faster than usual. The <b>boostPower</b> is the amount of power available for boosting. The <b>boostPowerRate</b> is the rate at which the boost power is replenished. The <b>boostRate</b> is the rate at which boosting uses power. And the <b>boostCooldownDuration</b> is the time the SpaceShip cannot boost, once all the boost power has been used up. Naturally all of these parameters must be non-negative.
         - The <b>boost shaking</b>, when the SpaceShip boosts, the camera shakes to create a more immersive effect. Two parameters can be used to adjust the effect. The <b>shakeFrequency</b> is the frequency with which the camera shakes. And the <b>shakeAmplitude</b> is the amount with which the camera shakes. Again these parameters must bee non-negative.
-        - The <b>lift</b> creates a more natural flight feeling through the addition of a lift force. There are again tow parameters that can be specified. The <b>lift</b> which is the lift force that is applied. And the <b>stallSpeed</b> which is the forward speed after which no more lift is generated.
