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:
sf::RectangleShape rectangle;
rectangle.setSize(sf::Vector2f(100, 50));
rectangle.setOutlineColor(sf::Color::Red);
rectangle.setOutlineThickness(5);
rectangle.setPosition(10, 20);
...
window.draw(rectangle);
void setOutlineColor(const Color &color)
Set the outline color of the shape.
void setOutlineThickness(float thickness)
Set the thickness of the shape's outline.

Constructor & Destructor Documentation
◆ RectangleShape()
Default constructor.
- Parameters
-
size Size of the rectangle
Member Function Documentation
◆ getFillColor()
|
inherited |
◆ getGlobalBounds()
|
inherited |
Get the global (non-minimal) 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 shape in the global 2D world's coordinate system.
This function does not necessarily return the minimal bounding rectangle. It merely ensures that the returned rectangle covers all the vertices (but possibly more). This allows for a fast approximation of the bounds as a first check; you may want to use more precise checks on top of that.
- 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()
|
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
◆ getOrigin()
|
inherited |
◆ getOutlineColor()
|
inherited |
◆ getOutlineThickness()
|
inherited |
Get the outline thickness of the shape.
- Returns
- Outline thickness of the shape
- See also
- setOutlineThickness
◆ getPoint()
|
virtual |
Get a point of the rectangle.
The returned point is in local coordinates, that is, the shape's transforms (position, rotation, scale) are not taken into account. The result is undefined if index is out of the valid range.
- Parameters
-
index Index of the point to get, in range [0 .. 3]
- Returns
- index-th point of the shape
Implements sf::Shape.
◆ getPointCount()
|
virtual |
Get the number of points defining the shape.
- Returns
- Number of points of the shape. For rectangle shapes, this number is always 4.
Implements sf::Shape.
◆ 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 |
◆ getSize()
| const Vector2f & sf::RectangleShape::getSize | ( | ) | const |
◆ getTexture()
|
inherited |
Get the source texture of the shape.
If the shape 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 shape's texture
- See also
- setTexture
◆ getTextureRect()
|
inherited |
Get the sub-rectangle of the texture displayed by the shape.
- Returns
- Texture rectangle of the shape
- 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:
- Parameters
-
offset 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:
sf::Vector2f pos = object.getPosition();
- Parameters
-
offsetX X offset offsetY Y 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
-
factor Scale factors
- 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
-
factorX Horizontal scale factor factorY Vertical scale factor
- See also
- setScale
◆ setFillColor()
|
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
-
color New color of the shape
- See also
- getFillColor, setOutlineColor
◆ 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
-
origin 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
-
x X coordinate of the new origin y Y coordinate of the new origin
- See also
- getOrigin
◆ setOutlineColor()
|
inherited |
Set the outline color of the shape.
By default, the shape's outline color is opaque white.
- Parameters
-
color New outline color of the shape
- See also
- getOutlineColor, setFillColor
◆ setOutlineThickness()
|
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
-
thickness New outline thickness
- See also
- getOutlineThickness
◆ 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
-
position 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
-
x X coordinate of the new position y Y coordinate of the 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 |
◆ setScale() [2/2]
|
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
◆ setSize()
| void sf::RectangleShape::setSize | ( | const Vector2f & | size | ) |
◆ setTexture()
|
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 behavior 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
-
texture New texture resetRect Should the texture rect be reset to the size of the new texture?
- See also
- getTexture, setTextureRect
◆ setTextureRect()
|
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
-
rect Rectangle defining the region of the texture to display
- See also
- getTextureRect, setTexture
◆ update()
|
protectedinherited |
Recompute the internal geometry of the shape.
This function must be called by the derived class everytime the shape's points change (i.e. the result of either getPointCount or getPoint is different).
