Especially when written “Entity Component System”, due to an ambiguity in the English language, a common interpretation of the name is that an ECS is a system comprising entities and components. For example, in the 2002 talk at GDC, [ 1 ] Scott Bilas compares a C++ object system and his new custom component system.
The C++ examples in this section demonstrate the principle of using composition and interfaces to achieve code reuse and polymorphism. Due to the C++ language not having a dedicated keyword to declare interfaces, the following C++ example uses inheritance from a pure abstract base class .
For example, a parent class, A, can have two subclasses B and C. Both B and C's parent class is A, but B and C are two separate subclasses. Hybrid inheritance Hybrid inheritance is when a mix of two or more of the above types of inheritance occurs. An example of this is when a class A has a subclass B which has two subclasses, C and D.

The components are details of the message, for example the message's text "Hello, world!" or perhaps the message's font or color. The system in this case is the entity-renderer, that renders messages to the screen. In this case, the system looks only at the text component of the entity and not other entity components.
English: A simple Entity Component System layout. Each entity is an index into the component tables. Each entity is an index into the component tables. An empty cell denotes that the corrisponding entity does not hold that component.
A national study discovered that teens in the United States consumed significantly less alcohol and drugs in 2024 compared to past years. Teen alcohol use has steadily decreased from 2000 to 2024 ...
The observer design pattern is a behavioural pattern listed among the 23 well-known "Gang of Four" design patterns that address recurring design challenges in order to design flexible and reusable object-oriented software, yielding objects that are easier to implement, change, test and reuse.
