Я пытаюсь получить доступ к скрипту из другого объекта, поэтому в конечном итоге я могу проверить наличие конфликта в массиве бонусов.

Я получаю объект исключительных исключений, не установленный в экземпляр. Я связал себя, если супы пытаются использовать разные решения. Я вернул его на голые кости и все еще имею проблему. Я поставлю скрипт gamemaster ниже, чтобы вы могли видеть полную картину.

Answer 1

Я решил это сделать общественное Int Я хотел настроить на столкновении статическую, а затем к нему доступ через скрипт у меня уже был, погубивший двух встречных предметов.

Я удалил powerupmaster, поскольку он больше не нужен.
