 ===== Extendable classes =====
-Some core types are flagged as **Extendable** in the documentation. This means an extendable type can be used as parent type when creating a custom type. In addition to new functions, you can override some base functions existing in the parent type, flagged as **virtual**.
+Some core types are flagged as **Extendable** in the documentation. This means an extendable type can be used as parent type when creating a custom type. In addition to new functions, you can override some base functions existing in the parent type, flagged as **Virtual function**. When extend a virtual function, define a new function for your custom type with the same type and parameters. You can call the parent function using the keyword ''super''.

 ===== Custom components =====
-When you define a new component type, you can assign it properties that are editable, usable in your component's behavior, and that can be saved in a savegame. Those properties must have a name and a type. They can also have a default value, flags, and access functions (getter and setter).

   * ''**create**()'': when the component is created
   * ''**init**()'': when the component is initialized in the game
