Struct CameraController 

pub struct CameraController {
    pub sensitivity: f32,
    pub zoom_sensitivity: f32,
    pub zoom_range: (f32, f32),
    /* private fields */
}

Camera controller for orbital movement around a target

Fields

sensitivity: f32

Movement sensitivity

zoom_sensitivity: f32

Zoom sensitivity

zoom_range: (f32, f32)

Minimum and maximum zoom distances

Implementations

impl CameraController

pub fn new() -> Self

Create a new camera controller

pub fn set_camera_entity(&mut self, entity: EntityId)

Set the camera entity this controller manages

pub fn set_center(&mut self, center: Point3<f32>)

Set the center point to orbit around

pub fn set_radius(&mut self, radius: f32)

Set the orbital distance

pub fn position(&self) -> Point3<f32>

Get the current camera position based on spherical coordinates

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

Create the view matrix for the current camera position

pub fn mouse_button(&mut self, button: MouseButton, state: ElementState)

Handle mouse button press/release

pub fn mouse_motion(&mut self, x: f32, y: f32) -> bool

Handle mouse movement - returns true if camera changed

pub fn mouse_wheel(&mut self, delta: f32) -> bool

Handle mouse wheel for zoom - returns true if camera changed

pub fn update_camera_transform(&self, world: &mut World)
