Specialized shape representing a convex polygon.
This class inherits all the functions of sf::Transformable (position, rotation, scale, bounds, ...) as well as the functions of sf::Shape (outline, color, texture, ...).
It is important to keep in mind that a convex shape must always be... convex, otherwise it may not be drawn correctly. Moreover, the points must be defined in order; using a random order would result in an incorrect shape.
Usage example:
Definition at line 42 of file ConvexShape.hpp.

explicit |
Default constructor.
| pointCount | Number of points of the polygon |
|
virtual |
Get the position of a point.
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.
| index | Index of the point to get, in range [0 .. getPointCount() - 1] |
Implements sf::Shape.
|
virtual |
Get the number of points of the polygon.
Implements sf::Shape.
| void sf::ConvexShape::setPoint | ( | std::size_t | index, |
| const Vector2f & | point | ||
| ) |
Set the position of a point.
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.
| index | Index of the point to change, in range [0 .. getPointCount() - 1] |
| point | New position of the point |
| void sf::ConvexShape::setPointCount | ( | std::size_t | count | ) |
Set the number of points of the polygon.
count must be greater than 2 to define a valid shape.
| count | New number of points of the polygon |
