Constructor Detail

Triangle

public Triangle()

Creates a new Triangle instance.

Method Detail

update

public void update()

Update the position of the triangle based on the velocity, if the triangle 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 triangle 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 triangle.

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.

Returns:

the change in y.

setSize

public void setSize(int newDiameter)

Set the diameter.

Parameters:

newDiameter - the new diameter.

setFrameDelay

public void setFrameDelay(int milliseconds)

Sets the delay in milliseconds between calls to move().

Parameters:

milliseconds - the delay in milliseconds.
