Помогите со скриптом на физику машины

[obi.stas]

У меня есть java скрипт на физику машины, но я не могу понять, как добавить центр тяжести машине.Вот скрипт:

Примените теги форматирования. Ваш пост не читаем.

Синтаксис:

Синтаксис: [ Показать ]

Используется csharp

public CoM : Gameobject

function Start()
{
    rigidbody.centerOfMass = CoM.localPosition;
}
 

Создаёшь на сцене пустой ГО, переносишь его в объект машины (чтобы он стал дочерним, а машина - родителем), выставляешь туда где тебе нужен центр масс, и перемещаешь его в поле скрипта

з.ы. скрипт - пипец просто ))

[Whity3D]

Всем привет! Дабы не плодить темы напишу тут. Меня тоже интересует скрипт для физики авто, но без использования WeelCollider. Мне не нужен готовый скрипт, объясните в общих чертах куда копать. Быть может есть где-то примеры?
Заранее спасибо!

Старая версия jCar не использовала WC.

А чем WC не устроил?

WC - тот же raycast, только для него уже реализованна сила трения и тд.
