Detailed Description

Drawable representation of a texture, with its own transformations, color, etc.

sf::Sprite is a drawable class that allows to easily display a texture (or a part of it) on a render target.

It inherits all the functions from sf::Transformable: position, rotation, scale, origin. It also adds sprite-specific properties such as the texture to use, the part of it to display, and some convenience functions to change the overall color of the sprite, or to get its bounding rectangle.

sf::Sprite works in combination with the sf::Texture class, which loads and provides the pixel data of a given texture.

The separation of sf::Sprite and sf::Texture allows more flexibility and better performances: indeed a sf::Texture is a heavy resource, and any operation on it is slow (often too slow for real-time applications). On the other side, a sf::Sprite is a lightweight object which can use the pixel data of a sf::Texture and draw it with its own transformation/color/blending attributes.

It is important to note that the sf::Sprite instance doesn't copy the texture that it uses, it only keeps a reference to it. Thus, a sf::Texture must not be destroyed while it is used by a sf::Sprite (i.e. never write a function that uses a local sf::Texture instance for creating a sprite).

Usage example:

// Declare and load a texture
sf::Texture texture;
texture.loadFromFile("texture.png");
// Create a sprite
sf::Sprite sprite;
sprite.setTexture(texture);
sprite.setTextureRect(sf::IntRect(10, 10, 50, 30));
sprite.setColor(sf::Color(255, 255, 255, 200));
sprite.setPosition(100, 25);
// Draw it
window.draw(sprite);

Member Function Documentation

const Color& sf::Sprite::getColor ( ) const

Get the global color of the sprite.

Returns
Global color of the sprite
See Also
setColor
FloatRect sf::Sprite::getGlobalBounds ( ) const

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
See Also
getTransform
FloatRect sf::Sprite::getLocalBounds ( ) const

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
const Vector2f& sf::Transformable::getOrigin ( ) const
inherited

get the local origin of the object

Returns
Current origin
See Also
setOrigin
const Vector2f& sf::Transformable::getPosition ( ) const
inherited

get the position of the object

Returns
Current position
See Also
setPosition
float sf::Transformable::getRotation ( ) const
inherited

get the orientation of the object

The rotation is always in the range [0, 360].

Returns
Current rotation, in degrees
See Also
setRotation
const Vector2f& sf::Transformable::getScale ( ) const
inherited

get the current scale of the object

Returns
Current scale factors
See Also
setScale
const Texture* sf::Sprite::getTexture ( ) const

Get the source texture of the sprite.

If the sprite has no source texture, a NULL pointer is returned. The returned pointer is const, which means that you can't modify the texture when you retrieve it with this function.

Returns
Pointer to the sprite's texture
See Also
setTexture
const IntRect& sf::Sprite::getTextureRect ( ) const

Get the sub-rectangle of the texture displayed by the sprite.

Returns
Texture rectangle of the sprite
See Also
setTextureRect
const Transform& sf::Transformable::getTransform ( ) const
inherited

get the combined transform of the object

Returns
Transform combining the position/rotation/scale/origin of the object
See Also
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::Sprite::setColor ( const Color color)

Set the global color of the sprite.

This color is modulated (multiplied) with the sprite's texture. It can be used to colorize the sprite, or change its global opacity. By default, the sprite's color is opaque white.

Parameters
colorNew color of the sprite
See Also
getColor
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::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::Sprite::setTexture ( const Texture texture,
bool  resetRect = false 
)

Change the source texture of the sprite.

The texture argument refers to a texture that must exist as long as the sprite uses it. Indeed, the sprite 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 sprite tries to use it, the behaviour is undefined. If resetRect is true, the TextureRect property of the sprite 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::Sprite::setTextureRect ( const IntRect rectangle)

Set the sub-rectangle of the texture that the sprite 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
rectangleRectangle defining the region of the texture to display
See Also
getTextureRect, setTexture
