Struct Entity 

pub struct Entity { /* private fields */ }

The fundamental entity in the engine, combining a transform with a collection of behavior-defining components.

Implementations

impl Entity

Implements static factory and ID generation methods for Entity.

pub fn generate_id() -> u64

Generates the next unique entity ID using a global atomic counter.

Returns

• u64 - The next unique ID.

pub fn create(name: &str) -> Entity

Creates a new entity with the given name and a default identity transform.

Arguments

• &str - The name of the entity.

Returns

• Entity - The newly created entity.

pub fn create_at(position: Vector2D) -> Entity

Creates a new entity at the specified position with a default name.

Arguments

• Vector2D - The initial position.

Returns

• Entity - The newly created entity.

impl Entity

Implements lifecycle and component management methods for Entity.

pub fn add_component(&mut self, component: ComponentRc)

Adds a component to this entity and calls its on_start lifecycle method.

Arguments

• ComponentRc - The component to add.

pub fn remove_component_by_name(&mut self, name: &str) -> Option<ComponentRc>

Removes the first component matching the given name.

Arguments

• &str - The component name to match.

Returns

• Option<ComponentRc> - The removed component, if found.

pub fn get_component_by_name(&self, name: &str) -> Option<ComponentRc>

Returns the first component matching the given name.

Arguments

• &str - The component name to match.

Returns

• Option<ComponentRc> - The matching component, if found.

pub fn update(&mut self, delta_time: f64)

Calls on_update on all active components.

Arguments

• f64 - The delta time in seconds.

pub fn render(&self, context: &CanvasRenderingContext2d)

Calls on_render on all active components.

Arguments

• &CanvasRenderingContext2d - The canvas rendering context.

pub fn destroy(&mut self)

Calls on_destroy on all components and clears the component list.

pub fn add_tag(&mut self, tag: String)

Adds a tag string to this entity.

Arguments

• String - The tag to add.

pub fn has_tag(&self, tag: &str) -> bool

Tests whether this entity has the given tag.

Arguments

• &str - The tag to check.

Returns

• bool - True if the tag is present.
