Detailed Description

Specialized shape representing a rectangle.

This class inherits all the functions of sf::Transformable (position, rotation, scale, bounds, ...) as well as the functions of sf::Shape (outline, color, texture, ...).

Usage example:

rectangle.setSize(sf::Vector2f(100, 50));
rectangle.setOutlineThickness(5);
rectangle.setPosition(10, 20);
...
window.draw(rectangle);

inherited

Get the fill color of the shape.

Returns
Fill color of the shape
See Also
setFillColor
FloatRect sf::Shape::getGlobalBounds ( ) const
inherited

Get the global bounding rectangle of the entity.

The returned rectangle is in global coordinates, which means that it takes in account the transformations (translation, rotation, scale, ...) that are applied to the entity. In other words, this function returns the bounds of the sprite in the global 2D world's coordinate system.

Returns
Global bounding rectangle of the entity
const Transform& sf::Transformable::getInverseTransform ( ) const
inherited

get the inverse of the combined transform of the object

Returns
Inverse of the combined transformations applied to the object

getTransform
FloatRect sf::Shape::getLocalBounds ( ) const
inherited

Get the local bounding rectangle of the entity.

The returned rectangle is in local coordinates, which means that it ignores the transformations (translation, rotation, scale, ...) that are applied to the entity. In other words, this function returns the bounds of the entity in the entity's coordinate system.

Returns
Local bounding rectangle of the entity

getInverseTransform
void sf::Transformable::move ( float  offsetX,
float  offsetY 
)
inherited

Move the object by a given offset.

This function adds to the current position of the object, unlike setPosition which overwrites it. Thus, it is equivalent to the following code:

sf::Vector2f pos = object.getPosition();
object.setPosition(pos.x + offsetX, pos.y + offsetY);
Parameters
offsetXX offset
offsetYY offset
See Also
setPosition
void sf::Transformable::move ( const Vector2f offset)
inherited

Move the object by a given offset.

This function adds to the current position of the object, unlike setPosition which overwrites it. Thus, it is equivalent to the following code:

object.setPosition(object.getPosition() + offset);
Parameters
offsetOffset
See Also
setPosition
void sf::Transformable::rotate ( float  angle)
inherited

Rotate the object.

This function adds to the current rotation of the object, unlike setRotation which overwrites it. Thus, it is equivalent to the following code:

object.setRotation(object.getRotation() + angle);
Parameters
angleAngle of rotation, in degrees
void sf::Transformable::scale ( float  factorX,
float  factorY 
)
inherited

Scale the object.

This function multiplies the current scale of the object, unlike setScale which overwrites it. Thus, it is equivalent to the following code:

sf::Vector2f scale = object.getScale();
object.setScale(scale.x * factorX, scale.y * factorY);
Parameters
factorXHorizontal scale factor
factorYVertical scale factor
See Also
setScale
void sf::Transformable::scale ( const Vector2f factor)
inherited

Scale the object.

This function multiplies the current scale of the object, unlike setScale which overwrites it. Thus, it is equivalent to the following code:

sf::Vector2f scale = object.getScale();
object.setScale(scale.x * factor.x, scale.y * factor.y);
Parameters
factorScale factors
See Also
setScale
void sf::Shape::setFillColor ( const Color color)
inherited

Set the fill color of the shape.

This color is modulated (multiplied) with the shape's texture if any. It can be used to colorize the shape, or change its global opacity. You can use sf::Color::Transparent to make the inside of the shape transparent, and have the outline alone. By default, the shape's fill color is opaque white.

Parameters
colorNew color of the shape
See Also
getFillColor, setOutlineColor
void sf::Transformable::setOrigin ( float  x,
float  y 
)
inherited

set the local origin of the object

The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

Parameters
xX coordinate of the new origin
yY coordinate of the new origin
See Also
getOrigin
void sf::Transformable::setOrigin ( const Vector2f origin)
inherited

set the local origin of the object

The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

Parameters
originNew origin
See Also
getOrigin
void sf::Shape::setOutlineColor ( const Color color)
inherited

Set the outline color of the shape.

By default, the shape's outline color is opaque white.

Parameters
colorNew outline color of the shape
See Also
getOutlineColor, setFillColor
void sf::Shape::setOutlineThickness ( float  thickness)
inherited

Set the thickness of the shape's outline.

Note that negative values are allowed (so that the outline expands towards the center of the shape), and using zero disables the outline. By default, the outline thickness is 0.

Parameters
thicknessNew outline thickness
See Also
getOutlineThickness
void sf::Transformable::setPosition ( float  x,
float  y 
)
inherited

set the position of the object

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable object is (0, 0).

Parameters
xX coordinate of the new position
yY coordinate of the new position
See Also
move, getPosition
void sf::Transformable::setPosition ( const Vector2f position)
inherited

set the position of the object

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable object is (0, 0).

Parameters
positionNew position
See Also
move, getPosition
void sf::Transformable::setRotation ( float  angle)
inherited

set the orientation of the object

This function completely overwrites the previous rotation. See the rotate function to add an angle based on the previous rotation instead. The default rotation of a transformable object is 0.

Parameters
angleNew rotation, in degrees
See Also
rotate, getRotation
void sf::Transformable::setScale ( float  factorX,
float  factorY 
)
inherited

set the scale factors of the object

This function completely overwrites the previous scale. See the scale function to add a factor based on the previous scale instead. The default scale of a transformable object is (1, 1).

Parameters
factorXNew horizontal scale factor
factorYNew vertical scale factor
See Also
scale, getScale
void sf::Transformable::setScale ( const Vector2f factors)
inherited

set the scale factors of the object

This function completely overwrites the previous scale. See the scale function to add a factor based on the previous scale instead. The default scale of a transformable object is (1, 1).

Parameters
factorsNew scale factors
See Also
scale, getScale
void sf::RectangleShape::setSize ( const Vector2f size)

Set the size of the rectangle.

Parameters
sizeNew size of the rectangle
See Also
getSize
void sf::Shape::setTexture ( const Texture texture,
bool  resetRect = false 
)
inherited

Change the source texture of the shape.

The texture argument refers to a texture that must exist as long as the shape uses it. Indeed, the shape doesn't store its own copy of the texture, but rather keeps a pointer to the one that you passed to this function. If the source texture is destroyed and the shape tries to use it, the behaviour is undefined. texture can be NULL to disable texturing. If resetRect is true, the TextureRect property of the shape is automatically adjusted to the size of the new texture. If it is false, the texture rect is left unchanged.

Parameters
textureNew texture
resetRectShould the texture rect be reset to the size of the new texture?
See Also
getTexture, setTextureRect
void sf::Shape::setTextureRect ( const IntRect rect)
inherited

Set the sub-rectangle of the texture that the shape will display.

The texture rect is useful when you don't want to display the whole texture, but rather a part of it. By default, the texture rect covers the entire texture.

Parameters
rectRectangle defining the region of the texture to display
See Also
getTextureRect, setTexture
void sf::Shape::update ( )
protectedinherited

Recompute the internal geometry of the shape.

This function must be called by the derived class everytime the shape's points change (ie. the result of either getPointCount or getPoint is different).
