Expand description
An entity index.
They are created using the Entities

They are used as indices with Components
structs.
Entities are conceptual “things” which possess attributes (Components). As an exemple, a Car (Entity) has a Color (Component), a Position (Component) and a Speed (Component).

Returns the index of this Entity
.
