我怎样才能使这个鞋子代码不让计算机陷入困境?

这是我的代码的当前状态,尽管我得到了预期的效果,但它并没有按照我需要的方式工作。 因为该程序处于无限循环中,所以显然它会不断地产生相互重叠的背景渐变,并且每个循环产生 10 个圆圈,很快它们就会过度生产并减慢程序的速度。

这里是这样的:

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do
            i = 0
# Animation loop
    animate ( 24 ) do |i|
# Variables For Randomized Colours
            randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            background randomCol..randomCol2
            fill    randomCol3
            stroke  randomCol4
            strokewidth     ( 0..5 ).rand
# Generate 10 circles per loop cycle
            10.times{
            i += 1
            oval :left => ( -5..self.width ).rand,
            :top => ( -5..self.height ).rand,
            :radius => ( 1..100 ).rand
            } end
        end

我已经尝试了我能想到的,但我不太熟悉 Ruby 的语法,或者我可以或不能用 Ruby 做的鞋子。 一些关于从这里去哪里的建议将不胜感激。

This is the current state of my code, and, although I get the desired effect, it's not working in the manner in which I need it to. Because the program is in an infinite loop, obviously it will produce both background gradients on top of one another constantly, and 10 circles with each loop, and quickly they overproduce themselves and slow the program right down.

Here goes:

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do
            i = 0
# Animation loop
    animate ( 24 ) do |i|
# Variables For Randomized Colours
            randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
            background randomCol..randomCol2
            fill    randomCol3
            stroke  randomCol4
            strokewidth     ( 0..5 ).rand
# Generate 10 circles per loop cycle
            10.times{
            i += 1
            oval :left => ( -5..self.width ).rand,
            :top => ( -5..self.height ).rand,
            :radius => ( 1..100 ).rand
            } end
        end

I've tried what I can think of, but I'm not overly familiar with Ruby's syntax, or what I can or can't do with shoes that I can do with Ruby. Some advice on where to go from here would be greatly appreciated.

您绘制的每个椭圆形和背景都是内存中的单独项目,这意味着它们会在一段时间后陷入困境。 如果您只想显示您绘制的最后一帧,那么您每次都需要清除应用程序:

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do

  # Animation loop
  animate ( 24 ) do |i|
    app.clear

    # Variables For Randomized Colours
    randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )

    background randomCol..randomCol2
    fill    randomCol3
    stroke  randomCol4
    strokewidth ( 0..5 ).rand

    # Generate 10 circles per loop cycle
    10.times do |i|
      i += 1
      oval :left => ( -5..self.width ).rand,
        :top => ( -5..self.height ).rand,
        :radius => ( 1..100 ).rand
    end
  end
end

这不像您原来的那样酷(除了它会无限期运行这一事实),因为您没有不再有层次感。 在这种情况下,我们可以让它运行几次再清除。 在这个例子中,每六次就会清除一次:

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do

  # Animation loop
  animate ( 24 ) do |i|
    app.clear if (i % 6 == 0)

    # Variables For Randomized Colours
    randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )

    background randomCol..randomCol2
    fill    randomCol3
    stroke  randomCol4
    strokewidth ( 0..5 ).rand

    # Generate 10 circles per loop cycle
    10.times do |i|
      i += 1
      oval :left => ( -5..self.width ).rand,
        :top => ( -5..self.height ).rand,
        :radius => ( 1..100 ).rand
    end
  end
end

现在一个更有趣的策略是保留最后的 n 遍并清除最旧的,这样我们总是有 6 层屏幕上(我发现 6 是一个很好的截止点,但您的意见(以及计算机的性能!)可能会有所不同):

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do
  n = 6
  @layers = []
  n.times { @layers << [] }
  # Animation loop
  animate ( 24 ) do |i|
    oldest = i % n
    # Clear out oldest frame
    @layers[oldest].each {|x| x.remove}
    @layers[oldest] = []

    # Variables For Randomized Colours
    randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )

    @layers[oldest] << background(randomCol..randomCol2)
    fill    randomCol3
    stroke  randomCol4
    strokewidth ( 0..5 ).rand

    # Generate 10 circles per loop cycle
    10.times do |i|
      @layers[oldest] << oval (:left => ( -5..self.width ).rand,
        :top => ( -5..self.height ).rand,
        :radius => ( 1..100 ).rand)
      end
  end
end

Each of those ovals and backgrounds you draw is a separate item in memory, which means they bog it down after a while. If you just want to show the last frame you drew, then you need to clear the app each time:

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do

  # Animation loop
  animate ( 24 ) do |i|
    app.clear

    # Variables For Randomized Colours
    randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )

    background randomCol..randomCol2
    fill    randomCol3
    stroke  randomCol4
    strokewidth ( 0..5 ).rand

    # Generate 10 circles per loop cycle
    10.times do |i|
      i += 1
      oval :left => ( -5..self.width ).rand,
        :top => ( -5..self.height ).rand,
        :radius => ( 1..100 ).rand
    end
  end
end

That's not as cool as your original one (other than the fact that it'll run indefinitely), because you don't have the layering effect any more. In that case, we can let it run through a few times before clearing. In this example, it'll clear every sixth time through:

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do

  # Animation loop
  animate ( 24 ) do |i|
    app.clear if (i % 6 == 0)

    # Variables For Randomized Colours
    randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )

    background randomCol..randomCol2
    fill    randomCol3
    stroke  randomCol4
    strokewidth ( 0..5 ).rand

    # Generate 10 circles per loop cycle
    10.times do |i|
      i += 1
      oval :left => ( -5..self.width ).rand,
        :top => ( -5..self.height ).rand,
        :radius => ( 1..100 ).rand
    end
  end
end

Now an even more interesting strategy would be to keep the last n passes and clear out the oldest, so that we always have, say, 6 layers on-screen (I find 6 to be a good cutoff point, but your opinion (and computer's performance!) may vary):

Shoes.app ( :title => 'Circles', :width => 500, :height => 500, :resizable => false ) do
  n = 6
  @layers = []
  n.times { @layers << [] }
  # Animation loop
  animate ( 24 ) do |i|
    oldest = i % n
    # Clear out oldest frame
    @layers[oldest].each {|x| x.remove}
    @layers[oldest] = []

    # Variables For Randomized Colours
    randomCol = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol2 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol3 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )
    randomCol4 = rgb( ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand, ( 0..255 ).rand )

    @layers[oldest] << background(randomCol..randomCol2)
    fill    randomCol3
    stroke  randomCol4
    strokewidth ( 0..5 ).rand

    # Generate 10 circles per loop cycle
    10.times do |i|
      @layers[oldest] << oval (:left => ( -5..self.width ).rand,
        :top => ( -5..self.height ).rand,
        :radius => ( 1..100 ).rand)
      end
  end
