Types

type Loop

type Loop struct {
	Receiver Receiver
	// contains filtered or unexported fields
}

Loop реалізує цикл подій для формування текстури отриманої через виконання операцій отриманих з внутрішньої черги.

func (*Loop) Post

func (l *Loop) Post(op Operation)

Post додає нову операцію у внутрішню чергу.

func (*Loop) Start

func (l *Loop) Start(s screen.Screen)

Start запускає цикл подій. Цей метод потрібно запустити до того, як викликати на ньому будь-які інші методи.

func (*Loop) StopAndWait

func (l *Loop) StopAndWait()

StopAndWait сигналізує про необхідність завершити цикл та блокується до моменту його повної зупинки.
