[+] Show declaration

pub struct Transform {
    needs_update: bool,

[−] Expand description

Position, rotation and scale of an object.

Every gameobject in a scene has (should have) a Transform. Its purpose is to store and manipulate the position, rotation and scale of the gameobject and determine its model matrix for rendering.

Fields

needs_update: bool

position: Vector3<f32>

rotation: Vector3<f32>

scale: Vector3<f32>

matrix: Matrix4<f32>

Methods

impl Transform

[−]

pub fn new() -> Transform

pub fn set_position(&mut self, position: Vector3<f32>)

[−]

Sets the transforms position in world coordinates.

pub fn set_rotation(&mut self, rotation: Vector3<f32>)

[−]

Sets the rotation of eulerAngles in the following order: (I hope the order is right and it is in degrees not radians)

• z degrees around the z axis
• x degrees around the x axis
• y degrees around the y axis

pub fn set_scale(&mut self, scale: Vector3<f32>)

[−]

Sets the scale of the object for each axis.

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

[−]

Sets the objects origin relative to world coordinates.

pub fn rotation(&self) -> Vector3<f32>

[−]

Returns the rotation of eulerAngles. x: yaw y: pitch z: roll

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

[−]

Returns the scale of the object for each axis.

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

[−]

Returns the model matrix according to scale, rotation and position of the object in world coordinates. Note: The object has to be mutable because it stores a model matrix, which will be updated in this function if some parameter has changed since the last matrix request.
