## ◆ sfCircleShape_move()

void sfCircleShape_move | ( | sfCircleShape * | shape,
|  | sfVector2f | offset )

Move a circle shape by a given offset.

This function adds to the current position of the object, unlike sfCircleShape_setPosition which overwrites it.

Parameters

  shape | Shape object
  offset | Offset

## ◆ sfCircleShape_rotate()

void sfCircleShape_rotate | ( | sfCircleShape * | shape,
|  | float | angle )

Rotate a circle shape.

This function adds to the current rotation of the object, unlike sfCircleShape_setRotation which overwrites it.

  angle | Angle of rotation, in degrees

## ◆ sfCircleShape_scale()

void sfCircleShape_scale | ( | sfCircleShape * | shape,
|  | sfVector2f | factors )

This function multiplies the current scale of the object, unlike sfCircleShape_setScale which overwrites it.

Parameters

  shape | Shape object
  factors | Scale factors

## ◆ sfCircleShape_setFillColor()

void sfCircleShape_setFillColor | ( | sfCircleShape * | shape,
|  | sfColor | color )

Set the fill color of a circle 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 sfTransparent to make the inside of the shape transparent, and have the outline alone. By default, the shape's fill color is opaque white.

Parameters

  shape | Shape object
  color | New color of the shape

## ◆ sfCircleShape_setOrigin()

void sfCircleShape_setOrigin | ( | sfCircleShape * | shape,
|  | sfVector2f | origin )

Set the local origin of a circle shape.

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 circle Shape object is (0, 0).

Parameters

  shape | Shape object
  origin | New origin

## ◆ sfCircleShape_setOutlineColor()

void sfCircleShape_setOutlineColor | ( | sfCircleShape * | shape,
|  | sfColor | color )

Set the outline color of a circle shape.

You can use sfTransparent to disable the outline. By default, the shape's outline color is opaque white.

Parameters

  shape | Shape object
  color | New outline color of the shape

## ◆ sfCircleShape_setOutlineThickness()

void sfCircleShape_setOutlineThickness | ( | sfCircleShape * | shape,
|  | float | thickness )

Set the thickness of a circle shape's outline.

This number cannot be negative. Using zero disables the outline. By default, the outline thickness is 0.

Parameters

  shape | Shape object
  thickness | New outline thickness

## ◆ sfCircleShape_setPointCount()

void sfCircleShape_setPointCount | ( | sfCircleShape * | shape,
|  | size_t | count )

Set the number of points of a circle.

Parameters

  shape | Shape object
  count | New number of points of the circle

## ◆ sfCircleShape_setPosition()

void sfCircleShape_setPosition | ( | sfCircleShape * | shape,
|  | sfVector2f | position )

Set the position of a circle shape.

This function completely overwrites the previous position. See sfCircleShape_move to apply an offset based on the previous position instead. The default position of a circle Shape object is (0, 0).

Parameters

  shape | Shape object
  position | New position

## ◆ sfCircleShape_setRadius()

void sfCircleShape_setRadius | ( | sfCircleShape * | shape,
|  | float | radius )

Set the radius of a circle.

Parameters

  shape | Shape object
  radius | New radius of the circle

## ◆ sfCircleShape_setRotation()

void sfCircleShape_setRotation | ( | sfCircleShape * | shape,
|  | float | angle )

Set the orientation of a circle shape.

This function completely overwrites the previous rotation. See sfCircleShape_rotate to add an angle based on the previous rotation instead. The default rotation of a circle Shape object is 0.

Parameters

  shape | Shape object
  angle | New rotation, in degrees

## ◆ sfCircleShape_setScale()

void sfCircleShape_setScale | ( | sfCircleShape * | shape,
|  | sfVector2f | scale )

Set the scale factors of a circle shape.

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

Parameters

  shape | Shape object
  scale | New scale factors

## ◆ sfCircleShape_setTexture()

void sfCircleShape_setTexture | ( | sfCircleShape * | shape,
|  | const sfTexture * | texture,
|  | bool | resetRect )

Change the source texture of a circle 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 behaviour 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

  shape | Shape object
  texture | New texture
  resetRect | Should the texture rect be reset to the size of the new texture?

## ◆ sfCircleShape_setTextureRect()

void sfCircleShape_setTextureRect | ( | sfCircleShape * | shape,
|  | sfIntRect | rect )

Set the sub-rectangle of the texture that a circle 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

  shape | Shape object
  rect | Rectangle defining the region of the texture to display
