impl Object

source

pub fn layer(&self) -> &Arc<Layer>

source

pub fn remove(self) -> NewObject

Removes the object from it’s layer.

source

pub fn to_new(&self) -> NewObject

Makes a new object from this object.

source

pub fn copy_new(&mut self, object: NewObject)

source

pub fn set_isometry(&mut self, position: Vec2, rotation: f32)

source

pub fn public_transform(&self) -> Transform

source

pub fn appearance(&self) -> &Appearance

source

pub fn id(&self) -> usize

Returns the identification number of the object specific the layer it is inside right now.

impl PartialEq for Object

source§

fn eq(&self, other: &Self) -> bool
