暂停和主屏幕不同

Question

我是一位经验不足的编码员，如果有人可以为我解决这个问题，那就太好了。

library(plotly)
ay <- list(
  tickfont = list(color = "red"),
  overlaying = "y",
  side = "right",
  title = "second y axis"
)
p <- plot_ly() %>%
  add_lines(x = ~1:3, y = ~10*(1:3), name = "slope of 10") %>%
  add_lines(x = ~2:4, y = ~1:3, name = "slope of 1", yaxis = "y2") %>%
  layout(
    title = "Double Y Axis", yaxis2 = ay,
    xaxis = list(title="x")
  )

}

ATM，我正在尝试制作它，因此起始屏幕与暂停屏幕不同。在开始屏幕上，我看到了欢迎和地球图片。在暂停的屏幕上，我希望它具有暂停符号的纹理。我知道这与这一行有关

我共同编写了一个简短的程序，向您展示如何使用枚举。启动应用程序时，它处于状态菜单中，并显示一个圆形和文本“菜单”。通常，您会从菜单状态转到游戏状态。但是在我的小应用程序中，您需要按Enter键，它从GAMEPLAY变为PAUSED并显示文本。我想您知道这个主意，希望对您进一步完善解决方案有帮助。
