Detailed Description

The "multi-shape" shape configuration.

Composes zero or more convex shapes into what can be a concave shape.

Member Function Documentation

MultiShapeConf & playrho::d2::MultiShapeConf::AddConvexHull	(	const VertexSet &	pointSet,
		NonNegative< Length >	vertexRadius = `GetDefaultVertexRadius()`
	)

noexcept

Creates a convex hull from the given set of local points. The size of the set must be in the range [1, MaxShapeVertices].

Warning: the points may be re-ordered, even if they form a convex polygon; collinear points are handled but not removed. Collinear points may lead to poor stacking behavior.

MultiShapeConf & playrho::d2::MultiShapeConf::Transform ( const Mat22 & m )

noexcept

Transforms the vertices of all the children by the given transformation matrix.
