Я начал с mapbox и пытаюсь анимировать трехмерный объект случайным образом, используя Tween. js. До сих пор мне удавалось перемещать объекты по прямым линиям только по определенным путям. Проблема в том, что эта часть: .to({ x: 300, y: 200 }, time) не работает с mapbox.
Я анимировал объекты, просто используя функцию onUpdate() Tween. js.
Я хочу перемещать объект случайным образом и в определенной области c только на медленной скорости. Кто-нибудь может мне помочь, пожалуйста?
