## ◆ sfConvexShape_move()

void sfConvexShape_move | ( | sfConvexShape * | shape,
|  | sfVector2f | offset )

Move a convex shape by a given offset.

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

Parameters

  shape | Shape object
  offset | Offset

## ◆ sfConvexShape_rotate()

void sfConvexShape_rotate | ( | sfConvexShape * | shape,
|  | float | angle )

Rotate a convex shape.

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

Parameters

  shape | Shape object
  angle | Angle of rotation, in degrees

## ◆ sfConvexShape_scale()

void sfConvexShape_scale | ( | sfConvexShape * | shape,
|  | sfVector2f | factors )

Scale a convex shape.

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

Parameters

  shape | Shape object
  factors | Scale factors

## ◆ sfConvexShape_setFillColor()

void sfConvexShape_setFillColor | ( | sfConvexShape * | shape,
|  | sfColor | color )

Set the fill color of a convex 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

## ◆ sfConvexShape_setOrigin()

void sfConvexShape_setOrigin | ( | sfConvexShape * | shape,
|  | sfVector2f | origin )

Set the local origin of a convex 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

## ◆ sfConvexShape_setOutlineColor()

void sfConvexShape_setOutlineColor | ( | sfConvexShape * | shape,
|  | sfColor | color )

Set the outline color of a convex 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

## ◆ sfConvexShape_setOutlineThickness()

void sfConvexShape_setOutlineThickness | ( | sfConvexShape * | shape,
|  | float | thickness )

Set the thickness of a convex 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

## ◆ sfConvexShape_setPoint()

void sfConvexShape_setPoint | ( | sfConvexShape * | shape,
|  | size_t | index,
|  | sfVector2f | point )

Set the position of a point in a convex shape.

Don't forget that the polygon must remain convex, and the points need to stay ordered! setPointCount must be called first in order to set the total number of points. The result is undefined if index is out of the valid range.

Parameters

  shape | Shape object
  index | Index of the point to change, in range [0 .. GetPointCount() - 1]
  point | New point

## ◆ sfConvexShape_setPointCount()

void sfConvexShape_setPointCount | ( | sfConvexShape * | shape,
|  | size_t | count )

Set the number of points of a convex shap.

count must be greater than 2 to define a valid shape.

Parameters

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

## ◆ sfConvexShape_setPosition()

void sfConvexShape_setPosition | ( | sfConvexShape * | shape,
|  | sfVector2f | position )

Set the position of a convex shape.

This function completely overwrites the previous position. See sfConvexShape_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

## ◆ sfConvexShape_setRotation()

void sfConvexShape_setRotation | ( | sfConvexShape * | shape,
|  | float | angle )

Set the orientation of a convex shape.

This function completely overwrites the previous rotation. See sfConvexShape_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

## ◆ sfConvexShape_setScale()

void sfConvexShape_setScale | ( | sfConvexShape * | shape,
|  | sfVector2f | scale )

Set the scale factors of a convex shape.

This function completely overwrites the previous scale. See sfConvexShape_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

## ◆ sfConvexShape_setTexture()

void sfConvexShape_setTexture | ( | sfConvexShape * | shape,
|  | const sfTexture * | texture,
|  | sfBool | resetRect )

Change the source texture of a convex 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?

## ◆ sfConvexShape_setTextureRect()

void sfConvexShape_setTextureRect | ( | sfConvexShape * | shape,
|  | sfIntRect | rect )

Set the sub-rectangle of the texture that a convex 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
