Specialized shape representing a circle.

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

Usage example:

Since the graphics carte tin't draw perfect circles, we have to fake them with multiple triangles continued to each other. The "points count" property of sf::CircleShape defines how many of these triangles to use, and therefore defines the quality of the circle.

The number of points can likewise exist used for some other purpose; with small numbers y'all tin create any regular polygon shape: equilateral triangle, square, pentagon, hexagon, ...

◆CircleShape()

sf::CircleShape::CircleShape	(	float	radius = `0`,
		std::size_t	pointCount = `xxx`
	)

explicit

Default constructor.

Parameters

radius	Radius of the circle
pointCount	Number of points composing the circle

◆getFillColor()

const Colour& sf::Shape::getFillColor ( ) const

Go the fill colour of the shape.

Returns: Fill color of the shape

Run across also: setFillColor

◆getGlobalBounds()

FloatRect sf::Shape::getGlobalBounds ( ) const

inherited

Get the global (not-minimal) bounding rectangle of the entity.

The returned rectangle is in global coordinates, which ways that information technology takes into account the transformations (translation, rotation, scale, ...) that are applied to the entity. In other words, this function returns the premises 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 perhaps more). This allows for a fast approximation of the bounds as a start cheque; yous may want to utilize more precise checks on top of that.

Returns: Global bounding rectangle of the entity

◆getInverseTransform()

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

◆getLocalBounds()

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 practical to the entity. In other words, this function returns the bounds of the entity in the entity's coordinate organization.

Returns: Local bounding rectangle of the entity

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

Parameters

thickness New outline thickness

Come across as well: getOutlineThickness

◆setPointCount()

void sf::CircleShape::setPointCount ( std::size_t count )

Set the number of points of the circle.

Parameters

radius New radius of the circle

Run across as well: getRadius

◆setRotation()

void sf::Transformable::setRotation ( float angle )

◆setScale() [1/2]

void sf::Transformable::setScale	(	bladder	factorX,
		float	manufacturing plant
	)

inherited

set the scale factors of the object

This function completely overwrites the previous scale. Come across the scale role 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
mill	New vertical scale factor

See also: scale, getScale

◆setScale() [2/2]

void sf::Transformable::setScale ( const Vector2f & factors )

inherited

set up the scale factors of the object

◆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 equally the shape uses it. Indeed, the shape doesn't store its own copy of the texture, but rather keeps a arrow to the i that yous passed to this role. If the source texture is destroyed and the shape tries to employ it, the behavior is undefined. texture tin exist 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?

Meet also: getTexture, setTextureRect

◆setTextureRect()

void sf::Shape::setTextureRect ( const IntRect & rect )

inherited

Prepare the sub-rectangle of the texture that the shape will brandish.

The texture rect is useful when yous don't want to brandish the whole texture, but rather a role 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 chosen by the derived course everytime the shape's points change (i.e. the result of either getPointCount or getPoint is dissimilar).
