Specialized shape representing a circle.

This class inherits all the functions of sf::Transformable (position, rotation, calibration, bounds, ...) besides as the functions of sf::Shape (outline, colour, texture, ...).

Usage example:

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

The number of points can also exist used for another purpose; with small numbers you can create any regular polygon shape: equilateral triangle, square, pentagon, hexagon, ...

void sf::Transformable::move ( bladder offsetX, float offsetY )

inherited

Move the object past a given offset.

This function adds to the current position of the object, unlike setPosition which overwrites it. Thus, it is equivalent to the post-obit code:

object.setPosition(pos.x + offsetX, pos.y + offsetY);

Parameters

offsetX	X offset
offsetY	Y offset

See likewise

setPosition

void sf::Transformable::move ( const Vector2f & start )

inherited

Move the object by a given start.

This function adds to the electric current position of the object, unlike setPosition which overwrites it. Thus, it is equivalent to the following lawmaking:

Parameters

See also

setPosition

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

inherited

Rotate the object.

This role adds to the current rotation of the object, unlike setRotation which overwrites it. Thus, information technology is equivalent to the post-obit code:

Parameters

bending

Angle of rotation, in degrees

void sf::Transformable::calibration ( float factorX, bladder factorY )

inherited

Calibration the object.

This function multiplies the current calibration of the object, different setScale which overwrites it. Thus, information technology is equivalent to the following code:

object.setScale(scale.x * factorX, scale.y * factorY);

Parameters

factorX	Horizontal scale factor
mill	Vertical calibration factor

See besides

setScale

void sf::Transformable::calibration ( const Vector2f & factor )

inherited

setScale

void sf::Shape::setFillColor ( const Colour & color )

inherited

Set up the fill colour of the shape.

This color is modulated (multiplied) with the shape's texture if whatever. It can be used to colorize the shape, or change its global opacity. You tin use sf::Colour::Transparent to make the inside of the shape transparent, and have the outline alone. By default, the shape's fill colour is opaque white.

Parameters

colour

New color of the shape

getFillColor, setOutlineColor

void sf::Transformable::setOrigin ( bladder 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 signal must be relative to the elevation-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

Parameters

10	X coordinate of the new origin
y	Y coordinate of the new origin

Run across also

getOrigin

void sf::Transformable::setOrigin ( const Vector2f & origin )

inherited

set up the local origin of the object

The origin of an object defines the heart bespeak for all transformations (position, scale, rotation). The coordinates of this bespeak 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

Meet also

getOrigin

void sf::Shape::setOutlineColor ( const Color & color )

inherited

Fix the outline colour of the shape.

By default, the shape'south outline colour is opaque white.

Parameters

color

New outline color of the shape

See also

getOutlineColor, setFillColor

void sf::Shape::setOutlineThickness ( bladder thickness )

inherited

Fix the thickness of the shape's outline.

Note that negative values are immune (and then 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

void sf::CircleShape::setPointCount

(

unsigned int

count

)

Set the number of points of the circle.

Parameters

count

New number of points of the circumvolve

Parameters

ten	X coordinate of the new position
y	Y coordinate of the new position

See also

move, getPosition

void sf::Transformable::setPosition ( const Vector2f & position )

inherited

prepare the position of the object

move, getPosition

void sf::CircleShape::setRadius

(

float

radius

)

Set the radius of the circle.

Parameters

radius

New radius of the circle

Parameters

bending

New rotation, in degrees

rotate, getRotation

void sf::Transformable::setScale ( float factorX, float factorY )

inherited

prepare the scale factors of the object

This role completely overwrites the previous scale. See the scale function to add a factor based on the previous calibration instead. The default scale of a transformable object is (1, 1).

Parameters

factorX	New horizontal scale factor
factorY	New vertical calibration factor

Come across also

scale, getScale

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

inherited

ready the scale factors of the object

This function completely overwrites the previous calibration. See the calibration function to add a cistron based on the previous calibration instead. The default calibration of a transformable object is (ane, 1).

Parameters

See also

calibration, getScale

void sf::Shape::setTexture ( const Texture * texture, bool resetRect = false )

inherited

Alter the source texture of the shape.

The texture argument refers to a texture that must exist equally long as the shape uses it. Indeed, the shape doesn't store its own re-create of the texture, but rather keeps a arrow to the i that you passed to this function. If the source texture is destroyed and the shape tries to utilize it, the behavior is undefined. texture tin can be NULL to disable texturing. If resetRect is truthful, the TextureRect property of the shape is automatically adjusted to the size of the new texture. If it is imitation, the texture rect is left unchanged.

Parameters

texture	New texture
resetRect	Should the texture rect exist reset to the size of the new texture?

Meet likewise

getTexture, setTextureRect

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

inherited

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

The texture rect is useful when you don't desire to brandish the whole texture, just 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

void sf::Shape::update ( )

protected inherited

Recompute the internal geometry of the shape.

This function must be called by the derived grade everytime the shape's points alter (i.e. the effect of either getPointCount or getPoint is different).
