[Unreal Engine][C++] How to create a custom CharacterMovementComponent

A Custom Character Movement Component

Used Unreal Engine Version: 4.22

Since the Unreal Engine Wiki is somewhat outdated in specific areas and I am not allowed to edit there, because they are working on a new one, I spare you the hassle to figure it out for yourself and present to you: the custom character movement component :D

If you want a character that supports more movement types, you have to extend character movement component. Here is how to do it:

First, create a new class inheriting from UCharacterMovementComponent:

// MainCharacterMovementComponent.h

UCLASS()
class MYGAME_API UMainCharacterMovementComponent : 
  public UCharacterMovementComponent
{
  GENERATED_BODY()
 
public:
  UMainCharacterMovementComponent(const FObjectInitializer& ObjectInitializer);

protected:
  virtual void InitializeComponent() override;

  virtual void TickComponent
  (
    float DeltaTime, 
    enum ELevelTick TickType, 
    FActorComponentTickFunction* ThisTickFunction
  ) override;
};

and implement it:

// MainCharacterMovementComponent.cpp

#include "MainCharacterMovementComponent.h"

UMainCharacterMovementComponent::UMainCharacterMovementComponent(const FObjectInitializer& ObjectInitializer)
 : Super(ObjectInitializer)
{
    // You stuff here
}

void UMainCharacterMovementComponent::InitializeComponent()
{
 Super::InitializeComponent();
}

//Tick Comp
void UMainCharacterMovementComponent::TickComponent
(
 float DeltaTime,
 enum ELevelTick TickType,
 FActorComponentTickFunction* ThisTickFunction
){
 Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
}

Then, extend ACharacter and replace it’s default UCharacterMovementComponent:

// ThirdPersonCharacter.h

UCLASS()
class MYGAME_API AThirdPersonCharacter : public ACharacter
{
 GENERATED_BODY()

public:

 // .............................................................. Constructor
 // Sets default values for this character's properties
 AThirdPersonCharacter(const FObjectInitializer& ObjectInitializer = FObjectInitializer::Get());
}

Then implement it like this to replace the component:

// ThirdPersonCharacter.cpp

AThirdPersonCharacter::AThirdPersonCharacter(const FObjectInitializer& ObjectInitializer)
 : Super(ObjectInitializer.SetDefaultSubobjectClass
 <UMainCharacterMovementComponent>(ACharacter::CharacterMovementComponentName))
{
    // Your implementation stuff here
}

Hope, this helps :)
