помогите разобраться с кодом, есть симулятор графических повреждений называется BeamNG drive, в интерфейсе есть скрипт который считывает время ( разгон до 100, торможение, называется perfomance timers ), как изменить код так чтобы тот считал время прохождения заданного расстояния допустим 1000 условных единиц (Считает он как в имперской системе так и в метрической), что нужно переделать, может нужно какие то переменные добавить?
