Система /engine, помогите

[_Diamond_]

Здравствуйте, я новичок в pawno, столкнулся с такой проблемой: пытаюсь сделать чтобы при заведении двигателя если у него допустим 500хп то шанс что авто заведётся будет например 1 к 5, если 1000 хп то кар заводится с 1 раза, если 300 хп то вообще не заводится. В гугле не нашёл, у самого не получается, кто поможет дам большой +
