I am participating in the nuggets Community game creative submission Contest. For details, please see: Game Creative Submission Contest

preface

Above we have placed the game character in the scene, the next thing to do is to let the game character in the scene to let it run, today, we will realize this function, through the keyboard W A S D keys to realize the role free running.

steps

To have a third-person view of the character as he runs, we first need to add a camera to the character.

Adding a Camera

Add a camera to the component.

Move the camera and the character, yes the character and the camera should be facing the blue arrow.

Then save the Settings.

Create GameMode

Click File-New Class and create GameMode and name it HeroGameMode. This will give you an extra HeroGameMode Class in your VS project.

Create the blueprint for GameMode

Go back to our scene, select Blueprints and create a New HeroGameMode blueprint.

This is called BP_HeroGameMode.

Specify role blueprints

Specify the role blueprint we created earlier, BP_Hero, in the details panel classes-Default Pawn Class on the right.

And then save.

Setting keyboard input

Click Project Settings, click Input in the left pane, and add the key mapping as shown.

Code control

Add the following code to the Hero class generated above in VS:

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

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "Hero.generated.h"

UCLASS(a)class ACTOREXAMPLE_API AHero : public ACharacter
{
	GENERATED_BODY(a)public:
	// Sets default values for this character's properties
	AHero(a);protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay(a) override;

public:	
	// Called every frame
	virtual void Tick(float DeltaTime) override;

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


	void MoveForward(float amount);

	void MoveBack(float amount);

	void MoveLeft(float amount);

	void MoveRight(float amount);

	void Yaw(float amount);

	void Pitch(float amount);
};

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


#include "Hero.h"

// Sets default values
AHero::AHero()
{
 	// Set this character to call Tick() every frame. You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;

}

// Called when the game starts or when spawned
void AHero::BeginPlay(a)
{
	Super::BeginPlay(a); }// Called every frame
void AHero::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

// Called to bind functionality to input
void AHero::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);
	PlayerInputComponent->BindAxis("Forward".this, &AHero::MoveForward);
	PlayerInputComponent->BindAxis("Back".this, &AHero::MoveBack);
	PlayerInputComponent->BindAxis("Left".this, &AHero::MoveLeft);
	PlayerInputComponent->BindAxis("Right".this, &AHero::MoveRight);
	PlayerInputComponent->BindAxis("Yaw".this, &AHero::Yaw);
	PlayerInputComponent->BindAxis("Pitch".this, &AHero::Pitch);
}

void AHero::MoveForward(float amount)
{
	if (Controller && amount)
	{
		FVector fwd = GetActorForwardVector(a);AddMovementInput(fwd, amount); }}void AHero::MoveBack(float amount)
{
	if (Controller && amount)
	{
		FVector back = -GetActorForwardVector(a);AddMovementInput(back, amount); }}void AHero::MoveLeft(float amount)
{
	if (Controller && amount)
	{
		FVector left = -GetActorRightVector(a);AddMovementInput(left, amount); }}void AHero::MoveRight(float amount)
{
	if (Controller && amount)
	{
		FVector right = GetActorRightVector(a);AddMovementInput(right, amount); }}void AHero::Yaw(float amount)
{
	if (Controller && amount)
	{
		AddControllerYawInput(200.0 f * amount * GetWorld() - >GetDeltaSeconds()); }}void AHero::Pitch(float amount)
{
	if (Controller && amount)
	{
		AddControllerPitchInput(200.0 f * amount * GetWorld() - >GetDeltaSeconds()); }}Copy the code

The engine will detect the key input we configured earlier, press the W key, and call the MoveForward function in the class, as will the other keys.

run

After pressing Play, you can control your character’s free movement by controlling the W A S D button.

The last

That’s the end of the tutorial, let’s go over what we’ve said.

  1. Add a camera to get a third-person view
  2. Create the GameMode class and GameMode blueprint, and specify the role blueprint
  3. Set the keyboard input mapping
  4. Write code to map the keyboard and control character walking

Isn’t it easy? Well, let’s call it a day!
