Title: Unreal Architecture
|
|
Crumbs:%ROOT%, Programming
|
|
Description:Reference to creating and implementing gameplay classes.
|
|
|
|
When programming gameplay elements using C++ code, each module can contain many C++ classes.
|
|
|
|
[REGION:raw]
|
|
|
|
[/REGION]
|
|
|
|
Each class defines a template for a new Actor or Object. Within the class header file, the class and any class [functions](Programming\UnrealArchitecture\Reference\Functions) and [properties](Programming\UnrealArchitecture\Reference\Properties)
|
|
are declared. Classes can also contain [structs](Programming\UnrealArchitecture\Reference\Structs), data structures that help with organization and manipulation of related properties. Structures can also be defined on their own.
|
|
[](Programming\UnrealArchitecture\Reference\Interfaces) allow additional gameplay behavior to be implemented by different classes.
|
|
|
|
When programming with Unreal Engine, it is possible to have standard C++ classes, functions, and variables. These can be defined using standard C++ syntax. However, `UCLASS()`, `UFUNCTION()`, and
|
|
`UPROPERTY()` macros can be used to make Unreal Engine aware of the new classes, functions, and variables. For instance, a variable with a declaration prefaced by a `UPROPERTY()` macro can
|
|
be garbage collected by the engine, and can be displayed and edited within Unreal Editor. There are also `UINTERFACE()` and `USTRUCT()` macros, and keywords for each macro that can be used
|
|
to specify the [class](Programming\UnrealArchitecture\Reference\Classes\Specifiers)'s, [function](Programming\UnrealArchitecture\Reference\Functions\Specifiers)'s, [property](Programming\UnrealArchitecture\Reference\Properties\Specifiers)'s,
|
|
[interface](Programming\UnrealArchitecture\Reference\Interfaces\Specifiers)'s, or [struct](Programming\UnrealArchitecture\Reference\Structs\Specifiers)'s behavior within Unreal Engine and Unreal Editor.
