5.3 Default Character Movement Controller Gravity Direction Greyed Out

Make a custom movement component that extends character movement component and add a custom function to override gravity


// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/CharacterMovementComponent.h"
#include "CharacterMovementComponentEX.generated.h"

/**

UCLASS()
class MYGAMENAME_API UCharacterMovementComponentEX : public UCharacterMovementComponent
{
	GENERATED_BODY()

	UFUNCTION(BlueprintCallable)
	void SetGravDirection(const FVector& GravityDir);
};

#include "CharacterMovementComponentEX.h"

void  UCharacterMovementComponentEX::SetGravDirection(const FVector& GravityDir) {
	Super::SetGravityDirection(GravityDir);
}

then inside of the character swap out the movement component with the new one

.h

// needs constructor (eg. class is called AMyCharacter)
AMyCharacter(const FObjectInitializer& ObjectInitializer);

cpp

/* needed include code */
#include "CharacterMovementComponentEX.h"


AMyCharacter::AMyCharacter(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer.SetDefaultSubobjectClass<UCharacterMovementComponentEX>(CharacterMovementComponentName))
{
// rest of your init code here if needed
}

With SetGravDirection you should be able to pass in a vector. Just to a cast to the CharacterMovementComponentEX class before calling the function.
