Поворот по направлению движения
У меня персонаж движется с помощью InputAxis на кнопки WASD. Камера игрока находится сверху. Но моделька не поворачивается в сторону движения.
Находил уроки где поворот персонажа идет в сторону указателя, но там определяется вектор от персонажа до указателя мыши.
А в моем случае как сделать? Подскажите, пожалуйста.
А как ты сам представляешь такое управление? Если не вводить мыш с указателем, то что по твоему должно будет произойти?
Поворот персонажа против часовой стрелки при нажатии "A" и по часовой при нажатии "D"?
Хотя наверное я не так понял вопрос.
Вообще ты можешь воспользоваться MakeRotFromX, используя в качестве вектора инпуты. Для x — вверх, вниз, для y — влево, вправо.
Мне кажется должен быть какой-то более изящный способ, но хз.

Спасибо за ответ. Я сейчас пробую просто поворот в зависимости от значения InputAxis (Compare float>SetControlRotation>MakeRotator). Вроде получается.
А я думал у движка есть автоматическое определение поворота от направления движения. Ведь AI персонажи которые бегут за игроком сами как-то поворачиваются. Но блюпринты относящиеся к этому я не нашел.
Всем привет�� Подскажите пожалуйста, как можно повернуть персонажа в напралении заданного
вектора направления? Я пробовал сделать так, что бы вокруг чара можно было крутить SpringArm с камерой, а по нажатию пкм ForwardVector чара должен был принимать значение ForwardVector'а спрингарма или камеры. Ну и если отжать пкм, то снова можно было бы вращать камеру вокруг чара. Первую часть я сделал, а как поворачивать чара в направлении вектора не додумкаю:(

Если тебе просто нужно двигать персонажа относительно камеры, то ты можешь просто взять мой вот этот код. Только замени мои методы передвижения на дефолтные
Не, именно поворачивать. Поворачивать чара в тоже направление что и SpringArm или камера
Setting Up Character Movement
In this Tutorial, you will create a playable character that exhibits different forms of Character Movement.
Character Movement provides a locomotion system for humanoid characters to traverse through your world. The Character Movement Component is an Actor Component that provides modes of movement for Character classes, including walking, falling, swimming, and flying. Additionally, the Character Movement Component features robust network gameplay integration and provides a framework to help developers create custom networked movement.
For additional documentation on Network Replication in Unreal Engine, refer to the Networking Overview .
In this How-To Gameplay Guide, you will create a Character class, script it’s movement logic, Input, and create an Animation Blueprint which will help determine which state your Character is in, and then play the corresponding animation.
Choose your implementation method:
Creating a New Project
Begin by signing into the Epic Games Launcher and creating a New > Games > Blank > Project named CharacterMovement.
To animate your Character, you will require the Animation Starter Pack which is available to download for free from the Epic Games Marketplace . Click the Free button to download and add the Animation Starter Pack to your Epic Games Library.
From your Library, search for your Animation Starter Pack and click Add to Project, then from the Select the Project to Add the Asset to menu, search for and select your CharacterMovement project file, then click Add to Project.
Upon adding the Animation Starter Pack to your project, you will notice its presence in the Content Browser.

Creating the Player Character
A Character class is required for your Player to control. A character is a pawn that comes with a Character Movement Component to provide a locomotion system for humanoid characters to traverse through your world. Follow the steps below to set up your character.
Click the Add/Import button to create a new Blueprint Character class named BP_PlayerCharacter.
Double-click your BP_PlayerCharacter to open its class defaults, then in the components tab select the Mesh(CharacterMesh0) Skeletal Mesh Component, and navigate to the Details panel.
Click image to expand.
In the Mesh category, select the drop down arrow adjacent to the Skeletal Mesh variable, and from the drop down menu select SK_Mannequin.
In the Details panel, navigate to the Transform category, and set the Mesh’s Location and Rotation to (0,0,-90).
Your Character’s Skeletal Mesh will now be oriented in the direction of the forward facing Arrow Component as shown in the image below.
Navigate to the Components tab to select your Mesh component, then click Add Component and in the drop down menu search for and select SpringArm, then name your Spring Arm Component «SpringArmComp«.
Navigate to the Details panel, and in the Camera Settings category enable the Use Pawn Control Rotation.
Enabling use Pawn Control rotation will rotate the camera relative to the spring arm.
In the Camera category, set the socket offset to (0,0,30) then navigate to the Transform category and set the SpringArmComp’s Location to (0,0,50).
With your SpringArmComp selected, click the Add Component button, then in the drop down menu search for and select Camera to add a Camera Component named CameraComp.
In the Components tab, select the Character Movement Component, then navigate to the Details panel, and in the Character Movement (Rotation Settings) category, enable Use Controller Desired Rotation and Orient Rotation To Movement.
In the Character Movement:Walking category enable the Ignore Base Rotation variable.
Setting Ignore base rotation to true will tell the character to maintain its current world rotation, and ignore any changes in rotation of the base it’s standing on.
In the Character Movement Nav Movement category, navigate to the Movement Capabilities and select the drop down arrow to reveal additional variable settings, navigate to the Can Crouch Boolean and click to enable it.
Compile and Save.

Как повернуть игрока в нужную сторону ue4
У меня персонаж движется с помощью InputAxis на кнопки WASD. Камера игрока находится сверху. Но моделька не поворачивается в сторону движения.
Находил уроки где поворот персонажа идет в сторону указателя, но там определяется вектор от персонажа до указателя мыши.
А в моем случае как сделать? Подскажите, пожалуйста.
А как ты сам представляешь такое управление? Если не вводить мыш с указателем, то что по твоему должно будет произойти?
Поворот персонажа против часовой стрелки при нажатии "A" и по часовой при нажатии "D"?
Хотя наверное я не так понял вопрос.
Вообще ты можешь воспользоваться MakeRotFromX, используя в качестве вектора инпуты. Для x — вверх, вниз, для y — влево, вправо.

Спасибо за ответ. Я сейчас пробую просто поворот в зависимости от значения InputAxis (Compare float>SetControlRotation>MakeRotator). Вроде получается.
А я думал у движка есть автоматическое определение поворота от направления движения. Ведь AI персонажи которые бегут за игроком сами как-то поворачиваются. Но блюпринты относящиеся к этому я не нашел.
В UE4, как мне повернуть тело моего персонажа вместе с камерой?
Я сделал простую анимацию в Blender и экспортировал ее в Unreal Engine 4. В игре персонаж появился с точки зрения третьего лица, но я сделал его похожим на первого лица, отрегулировав камеру.
Теперь, когда я включаю камеру в игру, я могу осмотреться в разных частях тела персонажа. (Например, если я повернуть направо, я вижу плечо своего персонажа, и если я столкнусь с фронтом, я вижу только запястья.) Всякий раз, когда я поворачиваю камеру и запускаю анимацию пуансона, она выглядит странно, потому что модель персонажа не является ‘t выровнен с камерой.
Как я могу заставить тело поворачиваться вместе с камерой, так что моя анимация выглядит правильно?
1 ответ
Это было сделано ранее в видеоуроке для «Ужасной игры». Они обозначают его «True FPS». Прямо сейчас это звучит так, как движение мыши перемещает камеру, а не тело. То, что вы хотите сделать, — это привязать камеру к гнезду на скелете (если вы хотите, чтобы камера двигалась вместе с анимацией). Если нет, вы можете просто поместить камеру там, где она вам нужна, а затем прикрепить ее к гнезду «Нет», когда вы присоедините ее к корневому компоненту или скелетной сетке. Указанный урок находится здесь. Он должен дать вам то, что вы хотите, исходя из вашего вопроса.
Чтобы быть ясным, ваш вопрос состоит в том, чтобы повернуть тело с помощью камеры. Это отвечает на ваш вопрос, потому что ваш поворотный вход будет перемещать как тело, так и камеру. Тем не менее, по технической ноте, камера не поворачивается, а камера поворачивается с телом из-за иерархии вложений. Я упомянул об этом, если вы хотите иметь отдельный вход, чтобы вызвать локальное преобразование только на камеру — вроде как в Legend of Zelda: Ocarina of Time, где вы можете использовать функцию «Look At /Look Around»
