Vector2 CalculateAccelerationToReachPoint (

Vector2	deltaPosition
Vector2	targetVelocity
Vector2	currentVelocity
float	acceleration
float	maxSpeed

)

Calculate an acceleration to move deltaPosition units and get there with approximately a velocity of targetVelocity.

Vector2 ClampVelocity (

Vector2	velocity	Desired velocity of the character. In world units per second.
float	maxSpeed	Max speed of the character. In world units per second.
float	slowdownFactor	Value between 0 and 1 which determines how much slower the character should move than normal. Normally 1 but should go to 0 when the character approaches the end of the path.
bool	slowWhenNotFacingTarget	Prevent the velocity from being too far away from the forward direction of the character and slow the character down if the desired velocity is not in the same direction as the forward vector.
Vector2	forward	Forward direction of the character. Used together with the slowWhenNotFacingTarget parameter.

)

Clamps the velocity to the max speed and optionally the forwards direction.

Note that all vectors are 2D vectors, not 3D vectors.
