Struct CameraComponent 

pub struct CameraComponent {
    pub fov: f32,
    pub znear: f32,
    pub zfar: f32,
    pub active: bool,
}

A camera lens attached to an entity. active marks the single camera entity Play mode should look through — a bool flag rather than a separate “active camera entity” reference, since entities aren’t referenced by stable ID across a scene save/load (scripts look entities up by name for the same reason). The UI is responsible for keeping at most one entity’s flag set (radio-button semantics, see editor::draw_camera_editor); World::active_camera defends against more than one somehow being set by just using the first it finds.

Fields

fov: f32

Vertical field of view, in degrees — same convention as Camera::fov.

znear: f32

zfar: f32

active: bool

Implementations

impl CameraComponent

pub fn derive_camera(&self, transform: &Transform, aspect: f32) -> Camera

Looks down local -Z, rotated by transform.rotation into world space, then converted to the yaw/pitch Camera stores via Camera::yaw_pitch_from_forward — any roll in transform.rotation is dropped, since the FPS-style Camera has no roll to express it with. aspect is viewport-derived, not stored on the component (mirrors how Renderer::resize keeps Camera::aspect current rather than baking it into camera data).
