Expand description

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

Required Methods§

Source

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

Sets the position of the object.

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

Source

fn set_rotation(&mut self, angle: f32)

Set the orientation of the object in degrees.

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.

Source

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).

Source

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).
