AbstractCenter X
Center Y
Unique name of the entity (used for lookup and serialization).
OptionalarrayZ-order for draw sorting (higher = drawn later / on top).
OptionalcustomWidth of the rectangle (centered on x).
Height of the rectangle (centered on y).
Default fill color for the rectangle (used in base draw implementation).
Current position (center point).
X coordinate (center).
Y coordinate (center).
Left edge of the bounding box.
Right edge of the bounding box.
Top edge of the bounding box.
Bottom edge of the bounding box.
Await the next emission of a specific event. Resolves with the arguments passed to that event.
Await the next emission of any one of the listed events. Resolves with { event: name, args: the arguments it received }
Registers a listener for the specified event.
Event name
The name of the event
The callback to invoke when the event is emitted
This emitter for chaining
Registers a listener for the specified event but returns a cleanup func.
Event name
The name of the event
The callback to invoke when the event is emitted
Registers a one-time listener for the specified event.
The listener is automatically removed after the first invocation.
Event name
The name of the event
The callback to invoke once
This emitter for chaining
Removes a listener for the specified event.
Event name
The name of the event
The callback to remove
This emitter for chaining
Emits an event, invoking all registered listeners with the provided arguments.
If the event is "error" and no listeners are registered, the first argument (the error)
will be thrown.
Event name
The name of the event to emit
Arguments to pass to listeners
true if any listeners were invoked, false otherwise
ProtectedemitEmits an event, invoking all registered listeners with the provided arguments.
If the event is "error" and no listeners are registered, the first argument (the error)
will be thrown.
Event name
The name of the event to emit
Arguments to pass to listeners
true if any listeners were invoked, false otherwise
Removes all listeners for the specified event, or all listeners if no event is provided.
Event name
Optionalevent: KOptional event name to clear listeners for
This emitter for chaining
Returns the number of listeners registered for the specified event.
Event name
The event to count listeners for
The number of registered listeners
Update entity.
Draw entity.
Optionalconfig: LocalUpdatableOperationConfig<T>Serializes the entity to a plain object (for save/load).
Excludes internal properties and respects nonSerializableProperties.
Serializable data
StaticdeserializeChecks for axis-aligned bounding box collision with another rectangular entity.
The other entity to check against
true if the bounding boxes overlap
AbstractupdateCalled once per tick with delta time (seconds).
Draws a filled rectangle centered on the entity's position.
Subclasses should override or call super.draw(ctx) if extending.
The 2D rendering context
Rectangular entity with centered position, width, height, and basic AABB collision.
Automatically handles translation and rotation for drawing if needed.
