Concave shape class.
This class has an interface and functionality similar to sf::ConvexShape, but is additionally able to work with shapes that are concave. It inherits the sf::Drawable and sf::Transformable classes.
| thor::ConcaveShape::ConcaveShape | ( | ) |
Creates an empty shape.
You can use setPointCount() and SetPoint() to build your own concave shape.
| thor::ConcaveShape::ConcaveShape | ( | const sf::Shape & | shape | ) |
Implicit constructor that adapts an existing sf::Shape.
The concave shape should look as similar as possible to the original convex shape.
| sf::FloatRect thor::ConcaveShape::getGlobalBounds | ( | ) | const |
Return transformed bounding rectangle.
This function does not necessarily yield the minimal bounding rect that spans all vertices. It transforms the local bounding rect, and then computes the bounding rect of that transformed bounding rect – so for example, a rotated shape might not have the bounding rect that you expect. This behavior is consistent with SFML.
| sf::Vector2f thor::ConcaveShape::getPoint | ( | std::size_t | index | ) | const |
Returns the position of a point.
| index | Which point? Must be in [0, getPointCount()[ |
| void thor::ConcaveShape::setOutlineThickness | ( | float | outlineThickness | ) |
sets the thickness of the shape's outline (0.f by default).
outlineThickness must be greater or equal to zero. If it is zero, no outline is visible.
| void thor::ConcaveShape::setPoint | ( | std::size_t | index, |
| sf::Vector2f | position | ||
| ) |
Sets the position of a point.
| index | Which point? Must be in [0, getPointCount()[ |
| position | New point position in local coordinates. |
