impl Transform

pub fn identity() -> Self

Creates new transform that has no effect, in other words any vector or matrix will remain unchanged if combined with identity transform.

pub fn position(&self) -> &InheritableVariable<Vector3<f32>>

Returns current position of transform.

pub fn set_position(&mut self, local_position: Vector3<f32>) -> &mut Self

Sets position of transform.

pub fn rotation(&self) -> &InheritableVariable<UnitQuaternion<f32>>

Returns current rotation quaternion of transform.

pub fn set_rotation(&mut self, local_rotation: UnitQuaternion<f32>) -> &mut Self

Sets rotation of transform.

pub fn scale(&self) -> &InheritableVariable<Vector3<f32>>

Returns current scale factor of transform.

pub fn set_scale(&mut self, local_scale: Vector3<f32>) -> &mut Self

Sets scale of transform.

pub fn set_pre_rotation( &mut self, pre_rotation: UnitQuaternion<f32>, ) -> &mut Self

Sets pre-rotation of transform. Usually pre-rotation can be used to change “coordinate” system of transform. It is mostly for FBX compatibility, and never used in other places of engine.

pub fn pre_rotation(&self) -> &InheritableVariable<UnitQuaternion<f32>>

Returns current pre-rotation of transform.

pub fn set_post_rotation( &mut self, post_rotation: UnitQuaternion<f32>, ) -> &mut Self

Sets post-rotation of transform. Usually post-rotation can be used to change “coordinate” system of transform. It is mostly for FBX compatibility, and never used in other places of engine.

pub fn post_rotation(&self) -> &InheritableVariable<UnitQuaternion<f32>>

Returns current post-rotation of transform.

pub fn set_rotation_offset( &mut self, rotation_offset: Vector3<f32>, ) -> &mut Self

Sets rotation offset of transform. Moves rotation pivot using given vector, it results in rotation being performed around rotation pivot with some offset.

pub fn rotation_offset(&self) -> &InheritableVariable<Vector3<f32>>

Returns current rotation offset of transform.

pub fn set_rotation_pivot(&mut self, rotation_pivot: Vector3<f32>) -> &mut Self

Sets rotation pivot of transform. This method sets a point around which all rotations will be performed. For example it can be used to rotate a cube around its vertex.

pub fn rotation_pivot(&self) -> &InheritableVariable<Vector3<f32>>

Returns current rotation pivot of transform.

pub fn set_scaling_offset(&mut self, scaling_offset: Vector3<f32>) -> &mut Self

Sets scaling offset. Scaling offset defines offset from position of scaling pivot.

pub fn scaling_offset(&self) -> &InheritableVariable<Vector3<f32>>

Returns current scaling offset of transform.

pub fn set_scaling_pivot(&mut self, scaling_pivot: Vector3<f32>) -> &mut Self

Sets scaling pivot. Scaling pivot sets a point around which scale will be performed.

pub fn scaling_pivot(&self) -> &InheritableVariable<Vector3<f32>>

Returns current scaling pivot of transform.

pub fn offset(&mut self, vec: Vector3<f32>) -> &mut Self

Shifts local position using given vector. It is a shortcut for: set_position(position() + offset)

pub fn matrix(&self) -> Matrix4<f32>

Returns matrix which is final result of transform. Matrix then can be used to transform a vector, or combine with other matrix, to make transform hierarchy for example.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Transform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str

In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly.
