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.
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::Vector2f thor::ConcaveShape::GetPoint | ( | unsigned int | 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 | ( | unsigned int | 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. |
