Decomposed transform defined by a position, a rotation and a scale.

Required methods

fn set_position<P: Into<Vector2f>>(&mut self, position: P)

Sets the position of the object.

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable object is (0, 0).

fn set_rotation(&mut self, angle: f32)

Set the orientation of the object.

This function completely overwrites the previous rotation. See the rotate function to add an angle based on the previous rotation instead. The default rotation of a transformable object is 0.

fn set_scale<S: Into<Vector2f>>(&mut self, scale: S)

Sets the scale factors of the object.

This function completely overwrites the previous scale. See the scale function to add a factor based on the previous scale instead. The default scale of a transformable object is (1, 1).

fn set_origin<O: Into<Vector2f>>(&mut self, origin: O)

Sets the local origin of the object.

The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0).

fn position(&self) -> Vector2f

Gets the position of the object.

fn rotation(&self) -> f32

Gets the rotation of the object.

The rotation is always in the range [0, 360].

fn get_scale(&self) -> Vector2f

Gets the current scale of the object.

fn origin(&self) -> Vector2f

Gets the local origin of the object.

fn move_<O: Into<Vector2f>>(&mut self, offset: O)

Moves the object by a given offset.

This function adds to the current position of the object, unlike Transformable::set_position which overwrites it.

fn rotate(&mut self, angle: f32)

Rotates the object.

This function adds to the current rotation of the object, unlike Transformable::set_rotation, which overwrites it.

fn scale<F: Into<Vector2f>>(&mut self, factors: F)

Scales the object.

This function multiplies the current scale of the object, unlike Transformable::set_scale, which overwrites it.

fn transform(&self) -> Transform

Gets the combined transform of the object.

fn inverse_transform(&self) -> Transform

Gets the inverse combined transform of the object.
