Unreal学习开发(一)

Actor

An Actor is any object that can be placed into a level, such as a Camera, static mesh, or player start location. Actors support 3D transformations such as translation, rotation, and scaling. They can be created (spawned) and destroyed through gameplay code (C++ or Blueprints).

In C++, AActor is the base class of all Actors

Each actor has a instigator, in new version it is private so ues GetInstigator() to get it .

Delegates

Data types that reference and execute member functions on C++ Objects.

• Single

• Multicast

  • Events

• Dynamic (UObject, serializable)

  Notes: Function should be tag as UFUNCTION()

Pawn

Pawn是可作为世界场景中”代理”的Actor。Pawn可被控制器所有，

• • AAIController

Character

PlayerInputComponent

Character basic control animation

Controller

• AController
  • PlayerController
  • AAIController

Weapon class

Add damage to a target dummy

• TSubclassOf

  /** type of damage */
  UPROPERTY(EditDefaultsOnly, Category=Damage)
  TSubclassOf<UDamageType> DamageType;

  Let designer choose demage type.

• Spawn an actor in world.

GetWorld()->SpawnActor<AActor>(ProjectileClass);

Weapon to Character need to set owner.

TPSCamera

CameraComp->SetFieldOfView(FOV);

terminology

OKR: Objective and key results

Muzzle: 枪口

Replicated：同步给服务端

定义component 起始字母为U(Uobject)，Actor 为A(Actor)

Black Magic

UE_4.26\Engine\Binaries\Win64 下UnrealHeaderTool.target

TypeName 行尾加一个空格。

可以加快编译速度。
