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).
See also the note on coordinates and undistorted rendering in sf::Transformable.
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.setPosition(100, 25);
// Draw it
window.draw(sprite);

Constructor & Destructor Documentation
◆ Sprite() [1/3]
| sf::Sprite::Sprite | ( | ) |
Default constructor.
Creates an empty sprite with no source texture.
◆ Sprite() [2/3]
|
explicit |
◆ Sprite() [3/3]
Construct the sprite from a sub-rectangle of a source texture.
- Parameters
-
texture Source texture rectangle Sub-rectangle of the texture to assign to the sprite
- See also
- setTexture, setTextureRect
Member Function Documentation
◆ getColor()
| const Color& sf::Sprite::getColor | ( | ) | const |
◆ getGlobalBounds()
| 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 into 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
◆ getInverseTransform()
|
inherited |
get the inverse of the combined transform of the object
- Returns
- Inverse of the combined transformations applied to the object
- See also
- getTransform
◆ getLocalBounds()
| 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
◆ getOrigin()
|
inherited |
◆ getPosition()
|
inherited |
◆ getRotation()
|
inherited |
get the orientation of the object
The rotation is always in the range [0, 360].
- Returns
- Current rotation, in degrees
- See also
- setRotation
◆ getScale()
|
inherited |
◆ getTexture()
| 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
◆ getTextureRect()
| 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
◆ getTransform()
|
inherited |
get the combined transform of the object
- Returns
- Transform combining the position/rotation/scale/origin of the object
- See also
- getInverseTransform
◆ move() [1/2]
|
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();
- Parameters
-
offsetX X offset offsetY Y offset
- See also
- setPosition
◆ move() [2/2]
|
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:
- Parameters
-
offset Offset
- See also
- setPosition
◆ rotate()
|
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:
- Parameters
-
angle Angle of rotation, in degrees
◆ scale() [1/2]
|
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:
- Parameters
-
factorX Horizontal scale factor factorY Vertical scale factor
- See also
- setScale
◆ scale() [2/2]
|
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:
- Parameters
-
factor Scale factors
- See also
- setScale
◆ setColor()
| 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
-
color New color of the sprite
- See also
- getColor
◆ setOrigin() [1/2]
|
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
-
x X coordinate of the new origin y Y coordinate of the new origin
- See also
- getOrigin
◆ setOrigin() [2/2]
|
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
-
origin New origin
- See also
- getOrigin
◆ setPosition() [1/2]
|
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
-
x X coordinate of the new position y Y coordinate of the new position
- See also
- move, getPosition
◆ setPosition() [2/2]
|
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
-
position New position
- See also
- move, getPosition
◆ setRotation()
|
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
-
angle New rotation, in degrees
- See also
- rotate, getRotation
◆ setScale() [1/2]
|
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
-
factorX New horizontal scale factor factorY New vertical scale factor
◆ setScale() [2/2]
|
inherited |
◆ setTexture()
| 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 behavior 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
-
texture New texture resetRect Should the texture rect be reset to the size of the new texture?
- See also
- getTexture, setTextureRect
◆ 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
-
rectangle Rectangle defining the region of the texture to display
- See also
- getTextureRect, setTexture
