xy::Transform Class Reference

Wraps the SFML transformable class in a component friendly format, parentable to other transforms in a scene graph hierachy. Transforms are non-copyable, but are moveable. More...

Public Member Functions
	Transform (const Transform &)=delete
	Transform (Transform &&) noexcept
Transform &	operator= (const Transform &)=delete
Transform &	operator= (Transform &&) noexcept
void	addChild (Transform &)
	Adds a child transform to this one.
void	removeChild (Transform &)
	Removes the given child transform from this one, if it exists, else does nothing.
sf::Transform	getWorldTransform () const
	Returns the world position of this transform by multiplying it with any parent transforms it may have.
sf::Vector2f	getWorldPosition () const
	Returns the world position of the transform. This is effectively a shortcut for getWorldTransform().transformPoint({}). If this transform does not have a parent transform then getPosition() is probably preferable.
float	getWorldRotation () const
	Returns the sum of this and all the transform's parents rotations if they exist, else returns the transform's current rotation.
std::size_t	getDepth () const
	Returns the depth of this transform in the scene hierachy. A value of 0 means it has no parent, 1 means one parent and so on.

Detailed Description

Wraps the SFML transformable class in a component friendly format, parentable to other transforms in a scene graph hierachy. Transforms are non-copyable, but are moveable.
