Struct sfml::graphics::Transformable

pub struct Transformable {
    // some fields omitted
}

Target for off-screen 2D rendering into a texture

Methods

impl Transformable

fn new() -> Option<Transformable>

Create a new transformable

Return Some(Transformable) or None

fn clone_opt(&self) -> Option<Transformable>

Copy an existing transformable

Return Some(Transformable) or None

fn set_position(&mut self, position: &Vector2f)

Set the position of a transformable

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 Transformable object is (0, 0).

Arguments

• position - The new position

fn set_rotation(&mut self, angle: f32)

Set the orientation of a transformable

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

Arguments

• angle - The new rotation, in degrees

fn set_scale(&mut self, scale: &Vector2f)

Set the scale factors of a transformable

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

Arguments

• scale - New scale factors

fn set_origin(&mut self, origin: &Vector2f)

Set the local origin of a transformable

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 Transformable object is (0, 0).

Arguments

• origin - New origin

fn get_position(&self) -> Vector2f

Get the position of a transformable

Return the current position

fn get_rotation(&self) -> f32

Get the orientation of a transformable

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

Return the current rotation, in degrees

fn get_scale(&self) -> Vector2f

Get the current scale of a transformable

Return the current scale factors

fn get_origin(&self) -> Vector2f

Get the local origin of a transformable

Return the current origin

fn move_(&mut self, offset: &Vector2f)

Move a transformable by a given offset

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

Arguments

• offset - Offset

fn rotate(&mut self, angle: f32)

Rotate a transformable

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

Arguments

• angle - Angle of rotation, in degrees

fn scale(&mut self, factors: &Vector2f)

Scale a transformable

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

Arguments

• factors - Scale factors

fn get_transform(&self) -> Transform

Get the combined transform of a transformable

Return the transform combining the position/rotation/scale/origin of the object

fn get_inverse_transform(&self) -> Transform

Get the inverse of the combined transform of a transformable

Return the inverse of the combined transformations applied to the object
