Crash when I add NPC class, from a exempla

[anon19956301]

I’m just posting again, so that you’ll see this reply. I had a dumb moment and you’ll probably feel a little silly after you look at the code again.
You’ve literally defined the SetupPlayerInputComponent function twice. Once as private in the header and once as public in the header.

#pragma once

include “GameFramework/Character.h”
include “Avatar.generated.h”

UCLASS()
class GOLDENEGG_API AAvatar : public ACharacter
{
GENERATED_UCLASS_BODY()

void SetupPlayerInputComponent(class UInputComponent* InputComponent) override; <-This shouldn’t be here
void MoveForward(float amount);
void MoveRight(float amount);
void MoveLeft(float amount);
void MoveBack(float amount);
void Yaw(float amount);
void Pitch(float amount);

public:
// Sets default values for this character’s properties
AAvatar();

// Called when the game starts or when spawned
virtual void BeginPlay() override;

// Called every frame
virtual void Tick( float DeltaSeconds ) override;

// Called to bind functionality to input
virtual void SetupPlayerInputComponent(class UInputComponent* InputComponent) override;

};

Out of curiosity, are you perhaps normally a Java developer?
I see several of your functions written like this:

void AAvatar::MoveRight(float amount){
if (Controller && amount){
FVector right = GetActorRightVector();
AddMovementInput(right, amount);
}
}

To where the first brace is on the same line as the function name and parameters. Nothing wrong with it, just wanted to see if that is where you’d adopted it from.
