Transformable

Interface for all entities that can be moved, rotated, and scaled. Sprites are good examples of entities that have this behavior.

Method Summary

Modifier and Type	Method and Description
`public Point2D`	getPosition() Gets the current position of this entity.
`public float`	getRotation() Gets the current rotational angle of this entity.
`public Point2D`	getScale() Gets the 2-dimensional scaling factor for this entity.
`public void`	move(float amountX, float amountY) Moves this entity the given distance.
`public void`	rotate(float angle) Rotates this entity the given number of degrees.
`public void`	setPosition(Point2D position) Sets the position of this entity.
`public void`	setPosition(float x, float y) Sets the position of this entity.
`public void`	setRotation(float angle) Sets the rotational angle of this entity.
`public void`	setScale(float scaleValue) Sets the scaling factor for this entity.
`public void`	setScale(float scaleX, float scaleY) Sets the scaling factor for this entity, specifying different values horizontally and vertically.

getPosition
public Point2D getPosition() Gets the current position of this entity. Returns: Current 2-dimensional position

getRotation
public float getRotation() Gets the current rotational angle of this entity. Returns: Rotational angle in degrees

getScale
public Point2D getScale() Gets the 2-dimensional scaling factor for this entity. Returns: The scaling factor over horizontal and vertical axes

move

public void move(
    float amountX,
    float amountY
)

Moves this entity the given distance. The translation will be relative to this entity's current position.

Parameters:

amountX	The horizontal translation
amountY	The vertical translation

rotate

public void rotate(
    float angle
)

Rotates this entity the given number of degrees. This rotation will be relative to this entity's current rotational angle.

Parameters:

angle

The angle in degrees to rotate

setPosition

public void setPosition(
    Point2D position
)

Sets the position of this entity.

Parameters:

position

The new position

setPosition

public void setPosition(
    float x,
    float y
)

Sets the position of this entity.

Parameters:

x	The x coordinate of the new position
y	The y coordinate of the new position

setRotation

public void setRotation(
    float angle
)

Sets the rotational angle of this entity.

Parameters:

angle

Rotational angle in degrees

setScale

public void setScale(
    float scaleValue
)

Sets the scaling factor for this entity. Horizontal and vertical scaling factors will be set to the same value.

Parameters:

scaleValue

Scaling factor

setScale

public void setScale(
    float scaleX,
    float scaleY
)

Sets the scaling factor for this entity, specifying different values horizontally and vertically.

Parameters:

scaleX	Horizontal scaling factor
scaleY	Vertical scaling factor
