  - - - Is A
        
        child is a parent - parent is not a child
        
        Child inherits all Parents variables and functions
      - Create Child From Blueprint
      - Polymorphism
      - Parent* variable
        
        A pointer to parent variable
        
        Can store address of any class in the inheritance chain
        
        down cast: convert a parent to a child variable and change it's pointer & where it points to
      - base class impact all derived classes
      - inheritance hierarchy
        
        share functionality that fit in inheritance hierarchy
      - Pitfalls of Deep Inheritance Hierarchies
      - Maintainability, base/parent class will change all code in children, no need to go to every child and rewrite in each child
      - AKA Inhertiance chain
      - Static Cast Vs Dynamic Cast
        
        RunTime Type checking
        
        If cast fails returns null
      - Example: UObject>AActor>APawn>ACharacter
      - Virtual [FunctionName] override;
    - - Has A
        
        a class that contains another class
        
        Outer class contains inner class
        
        Example: Package Class>World Class>Level Class>Actor Class>Component Class
        
        Subclass / SubOject
        
        A Actor Class is sub object of Level Class, Level Class is a sub object of world class
        
        Assets - Not a sub object, its stored inside package class tho
      - Actor Component
      - share functionality that DOESNT fit in inheritance hierarchy
      - actor needs just specific functionality and not all of parents features
      - scene component
  - - - Encapsulation refers to the practice of restricting access to certain components of an object and only exposing a limited interface to the outside world.

        protected
  - - - AActor* VarName;
        
        VarName = &OtherVarName
      - GetOwner();
      - stores an memory address of another variable(which will give u a value)
      - Dereferencing
        
        *Type
        
        (*Variable).Method()
        
        -> arrow operator
      - Type*
      - &Variable
      - pointer isn't a data type, it a variable that stores an addres
    - - stores the value at it's address
  - - - deletes data that isn't being referenced anymore
    - - Autogenerate code
      - include "Items.generated.h"
        
        example, from Items.h file, .generated.h contains the generated code UHT will use to auto generate code
      - uses Macros and places code in their place

      - Should Ignore
- - - - Unit vector
        
        Useful if need just direction
      - Used to represent Orientation of an actor
      - Direction = V / | v |
        
        Direction = ( X / |v|, Y / |v|, Z / |v|)
      - magnitude of 1
        
        useful for direction * speed
      - facing direction, movement input, projectile direction, line tracing
    - - Length / Distance
      - |v | = Squared( X2 + Y2 + Z2)
        
        calculate magnitude from Origin
      - distance from tail to head, you need both of these to calculate |v|
    - - 3 Scalar values in Degrees
      - Roll(X axis / Forward), Pitch(Y / Right axis), Yaw(Z axis / Up)
      - Forward, Right, Up
      - Represents rotation of an actor with a vector
      - Left hand right hand coordinate system
    - - Component Wise Addition
      - Add the tail of new Vector to Head of old Vector
    - - Component Wise Subtraction
      - subtract the tail from head
    - - do component wise subtraction, than
    - - For Actors in scene, location vector specifics position of the actor in 3D world space
