2D Игра. Часть 1. Создание и раскраска персонажа используя шейдер маски (видеоурок)

В этом видео уроке я покажу вам как создать и раскрасить 2d персонажа в Unity используя шейдер цветовой маски. Я написал такой шейдер и скрипт для кастомизации персонажа.

Часть 2. Мультиспрайтовый 2D персонаж с несколькими состояниями

Это первая часть моих уроков по 2d играм.

В демо я использую мой селектор цветов. Вы можете найти его тут.
