## Constructor & Destructor Documentation

## ◆ RectangleShape()

sf::RectangleShape::RectangleShape | ( | Vector2f | size = {} | ) |
| explicit

Default constructor.

Parameters

  size | Size of the rectangle

## Member Function Documentation

## ◆ getFillColor()

Color sf::Shape::getFillColor | ( |  | ) | const
| nodiscard inherited

Get the fill color of the shape.

Returns
  Fill color of the shape

See also
  `setFillColor`

## ◆ getGeometricCenter()

Vector2f sf::RectangleShape::getGeometricCenter | ( |  | ) | const
| nodiscard override virtual

Get the geometric center of the rectangle.

The returned point is in local coordinates, that is, the shape's transforms (position, rotation, scale) are not taken into account.

Returns
  The geometric center of the shape

Reimplemented from sf::Shape.

## ◆ getGlobalBounds()

FloatRect sf::Shape::getGlobalBounds | ( |  | ) | const
| nodiscard 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()

const Transform & sf::Transformable::getInverseTransform | ( |  | ) | const
| nodiscard 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::Shape::getLocalBounds | ( |  | ) | const
| nodiscard 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()

Vector2f sf::Transformable::getOrigin | ( |  | ) | const
| nodiscard inherited

get the local origin of the object

Returns
  Current origin

See also
  `setOrigin`

## ◆ getOutlineColor()

Color sf::Shape::getOutlineColor | ( |  | ) | const
| nodiscard inherited

Get the outline color of the shape.

Returns
  Outline color of the shape

See also
  `setOutlineColor`

## ◆ getOutlineThickness()

float sf::Shape::getOutlineThickness | ( |  | ) | const
| nodiscard inherited

Get the outline thickness of the shape.

Returns
  Outline thickness of the shape

See also
  `setOutlineThickness`

## ◆ getPoint()

Vector2f sf::RectangleShape::getPoint | ( | std::size_t | index | ) | const
| nodiscard override 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()

std::size_t sf::RectangleShape::getPointCount | ( |  | ) | const
| nodiscard override 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()

Vector2f sf::Transformable::getPosition | ( |  | ) | const
| nodiscard inherited

get the position of the object

Returns
  Current position

See also
  `setPosition`

## ◆ getRotation()

Angle sf::Transformable::getRotation | ( |  | ) | const
| nodiscard inherited

get the orientation of the object

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

Returns
  Current rotation

See also
  `setRotation`

## ◆ getScale()

Vector2f sf::Transformable::getScale | ( |  | ) | const
| nodiscard inherited

get the current scale of the object

Returns
  Current scale factors

See also
  `setScale`

## ◆ getSize()

See also
  `setSize`

## ◆ getTexture()

const Texture * sf::Shape::getTexture | ( |  | ) | const
| nodiscard inherited

Get the source texture of the shape.

If the shape has no source texture, a `nullptr` 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()

const IntRect & sf::Shape::getTextureRect | ( |  | ) | const
| nodiscard inherited

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

Returns
  Texture rectangle of the shape

See also
  `setTextureRect`

## ◆ getTransform()

const Transform & sf::Transformable::getTransform | ( |  | ) | const
| nodiscard inherited

get the combined transform of the object

Returns
  Transform combining the position/rotation/scale/origin of the object

See also
  `getInverseTransform`

## ◆ move()

void sf::Transformable::move | ( | 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);
sf::Transformable::getPosition
Vector2f getPosition() const
get the position of the object

Parameters

  offset | Offset

See also
  `setPosition`

## ◆ rotate()

void sf::Transformable::rotate | ( | Angle | 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);
sf::Transformable::getRotation
Angle getRotation() const
get the orientation of the object

Parameters

  angle | Angle of rotation

## ◆ scale()

void sf::Transformable::scale | ( | 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);
sf::Transformable::scale
void scale(Vector2f factor)
Scale the object.

Parameters

  factor | Scale factors

See also
  `setScale`

## ◆ setFillColor()

void sf::Shape::setFillColor | ( | 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

  color | New color of the shape

See also
  `getFillColor`, `setOutlineColor`

## ◆ setOrigin()

void sf::Transformable::setOrigin | ( | 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

  origin | New origin

See also
  `getOrigin`

## ◆ setOutlineColor()

void sf::Shape::setOutlineColor | ( | Color | color | ) |
| 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()

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

  thickness | New outline thickness

See also
  `getOutlineThickness`

## ◆ setPosition()

void sf::Transformable::setPosition | ( | 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

  position | New position

See also
  `move`, `getPosition`

## ◆ setRotation()

void sf::Transformable::setRotation | ( | Angle | 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

  angle | New rotation

See also
  `rotate`, `getRotation`

## ◆ setScale()

void sf::Transformable::setScale | ( | 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

  factors | New scale factors

See also
  `scale`, `getScale`

## ◆ setSize()

void sf::RectangleShape::setSize | ( | Vector2f | size | ) |

Set the size of the rectangle.

Parameters

  size | New size of the rectangle

See also
  `getSize`

## ◆ setTexture()

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 behavior is undefined. `texture` can be a null pointer 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()

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

  rect | Rectangle defining the region of the texture to display

See also
  `getTextureRect`, `setTexture`

## ◆ update()

void sf::Shape::update | ( |  | ) |
| protected inherited

Recompute the internal geometry of the shape.

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