Constructor Detail

Dynamic2D

public Dynamic2D()

Default constructor.

Dynamic2D

public Dynamic2D(int duration,
         float count)

Constructor setting the speed of interpolation and the number of revolutions. What constitutes 'one revolution' depends on the MODE: Dynamic.MODE_LOOP, Dynamic.MODE_PATH or Dynamic.MODE_JUMP.

Parameters:

duration - number of milliseconds it takes to do one revolution.

count - number of revolutions we will do. Count<=0 means 'infinite'.

Method Detail

getPoint

public Static2D getPoint(int location)

Returns the location'th Static2D.

Parameters:

location - the index of the Point we are interested in.

Returns:

The Static2D, if 0<=location<getNumPoints(), or null otherwise.

setPoint

public void setPoint(int location,
            float x,
            float y)

Resets the location'th Point.

Parameters:

location - the index of the Point we are setting.

x - New value of its first float.

add

public void add(Static2D v)

Adds a new Static2D to the end of our list of Points to interpolate through.

Only a reference to the Point gets added to the List; this means that one can add a Point here, and later on Static2D.set(float,float) it to some new value and the change will be seamlessly reflected in the interpolated path.

A Point can be added multiple times.

Parameters:

v - The Point to add.

add

public void add(int location,
       Static2D v)

Adds a new Static2D to the location'th place in our List of Points to interpolate through.

Parameters:

location - Index in our List to add the new Point at.

v - The Point to add.

remove

public boolean remove(Static2D v)

Removes all occurrences of Point v from the List of Points to interpolate through.

Parameters:

v - The Point to remove.

Returns:

true if we have removed at least one Point.

remove

public boolean remove(int location)

Removes a location'th Point from the List of Points we interpolate through.

Parameters:

location - index of the Point we want to remove.

Returns:

true if location is valid, i.e. if 0<=location<getNumPoints().

removeAll

public void removeAll()

Removes all Points.

setNoise

public void setNoise(Static2D noise)

Sets the 'smoothness' of interpolation.

When Noise=0 (the default), we interpolate between our Points through the most smooth path possible. Increasing noise makes the Dynamic increasingly deviate from this path, pseudo-randomly speeding up and slowing down, etc.

Parameters:

noise - The noise level. Permitted range: 0 <= noise <= 1.
