// Purpose: Defines the interface to a game class as defined by the game data
|
|
// file (FGD). Each class is type of entity that can be placed in
|
|
// the editor and has attributes such as: keys that may be set,
|
|
// the default size and color of the entity, inputs and outputs,
|
|
// and any default models that are created when the entity is placed.
|
|
//
|
|
// The game classes support multiple inheritence through aggregation
|
|
// of properties.
