Constructor Detail

Oval

public Oval()

Creates a new Oval instance.

Method Detail

update

public void update()

Update the position of the oval based on the velocity, if the oval hits a wall, reverses velocity in the appropriate direction.

Specified by:

update in interface Shape

setAcceleration

public void setAcceleration(Vector dV)

Sets the acceleration (change in velocity) of the oval using a vector.

Specified by:

setAcceleration in interface Shape

Parameters:

dV - the acceleration (change in velocity) vector

setVelocity

public void setVelocity(int dx,
                        int dy)

Sets the velocity, in the x and y directions of the oval.

Parameters:

dx - the new change in x value.

dy - the new change in y value.

getDx

public int getDx()

Get the change in x.

Returns:

the change in x.

getDy

public int getDy()

Get the change in y.
