Issue
Это мой код для моей игры. Кирпич падает и ударяет в сторону квадрата. Чтобы определить, какая сторона поражена, появляются четыре треугольника, которые образуют квадрат. Они невидимы с низкой непрозрачностью. Я не получаю никакого контакта между узлом кирпича и узлом треугольника. Кусок кирпича просто падает прямо через площадь. Любая помощь?
