C# Класс Project290.Physics.Collision.Shapes.Shape

A shape is used for collision detection. You can create a shape however you like. Shapes used for simulation in World are created automatically when a Fixture is created. Shapes may encapsulate a one or more child shapes.

Открытые методы

Метод	Описание
Clone ( ) : Shape	Clone the concrete shape
ComputeAABB ( AABB &aabb, Transform &transform, int childIndex ) : void	Given a transform, compute the associated axis aligned bounding box for a child shape.
ComputeProperties ( ) : void	Compute the mass properties of this shape using its dimensions and density. The inertia tensor is computed about the local origin, not the centroid.
RayCast ( RayCastOutput &output, RayCastInput &input, Transform &transform, int childIndex ) : bool	Cast a ray against a child shape.
TestPoint ( Transform &transform, Vector2 &point ) : bool	Test a point for containment in this shape. This only works for convex shapes.

Описание методов

Clone() публичный абстрактный Метод

Clone the concrete shape

public abstract Clone ( ) : Shape
Результат	Shape

ComputeAABB() публичный абстрактный Метод

Given a transform, compute the associated axis aligned bounding box for a child shape.

public abstract ComputeAABB ( AABB &aabb, Transform &transform, int childIndex ) : void
aabb	AABB	The aabb results.
transform	Transform	The world transform of the shape.
childIndex	int	The child shape index.
Результат	void

ComputeProperties() публичный абстрактный Метод

Compute the mass properties of this shape using its dimensions and density. The inertia tensor is computed about the local origin, not the centroid.

public abstract ComputeProperties ( ) : void
Результат	void

RayCast() публичный абстрактный Метод

Cast a ray against a child shape.

public abstract RayCast ( RayCastOutput &output, RayCastInput &input, Transform &transform, int childIndex ) : bool
output	RayCastOutput	The ray-cast results.
input	RayCastInput	The ray-cast input parameters.
transform	Transform	The transform to be applied to the shape.
childIndex	int	The child shape index.
Результат	bool

Shape() защищенный Метод
