void setScale(const Vector2f &factors)
set the scale factors of the object
void setPosition(float x, float y)
set the position of the object
void setOrigin(float x, float y)
set the local origin of the object
const Vector2f & getScale() const
get the current scale of the object
void move(float offsetX, float offsetY)
Move the object by a given offset.
const Vector2f & getOrigin() const
get the local origin of the object
float getRotation() const
