type Component ¶

type Component interface {
	Name() string
}

Component is a generic struct with data in them for systems to utilize.

type ComponentManager ¶

type ComponentManager interface {
	// Register will reserve a new ID by the given name for a component.
	Register(name string)

	// Read will return the component data by name for the given entity.
	Read(entity entity.Entity, name string) Component

	// Remove will delete the given component by name on the given entity.
	Remove(entity entity.Entity, name string)

	// Attach will assign a component data by name to the given entity.
	Attach(entity entity.Entity, name string, component Component)

	// Sign will create a signature for the given components by name that can be
	// assigned to an entity.
	Sign(names ...string) *bitset.BitSet

	// Signature will return the ID of a component by name.
