Struct Transform

pub struct Transform {
    pub position: Vec3,
    pub rotation: Vec3,
    pub scale: Vec3,
    /* private fields */
}

A 3D representation of an entity’s position, rotation and scale.

A Transform contains Vec3s for Position, ROtation and Scale.

Fields

position: Vec3

Position component of the Transform.

rotation: Vec3

Rotation component of the Transform.

scale: Vec3

Scale component of the Transform.

Implementations

impl Transform

pub fn new() -> Self

Create a new Transform with default values.

pub fn new_with_position(position: Vec3) -> Self

Create a new Transform with an initial position.

pub fn matrix(&self) -> Mat4

Get a clone of the Mat4.

pub fn matrix_slice(&mut self) -> &[f32]

Get the Mat4 representing the transform as a slice of f32 to use with WebGL.

pub fn set_position(&mut self, position: Vec3)

Set the Transform’s position and calculate its matrix.

pub fn set_rotation(&mut self, rotation: f32)

Set the Transform’s rotation and calculate its matrix.

pub fn set_scale(&mut self, scale: Vec3)

Set the Transform’s scale and calculate its matrix.

pub fn get_position(&self) -> &[f32]

Get the position as a slice.

pub fn get_rotation(&self) -> f32

Get the rotation as an f32.

pub fn get_scale(&self) -> &[f32]

Get the scale as a slice.
