未來簡單式

If you've seen some of my other videos, you'll know I like making games with redstone.

如果你看過我的其他視頻，你就會知道我喜歡用紅石製作遊戲。

動名詞

I really like making games with redstone.

How do my projects get built from start to end?

我的項目是如何從頭到尾完成的？

Today, hopefully, I'm going to answer those questions and take you along with me on my journey to build Flappy Bird with just redstone.

今天，我希望能回答你的這些問題，並帶你一起踏上用紅石製作 Flappy Bird 的旅程。

Flappy Bird is a mobile game by Miniclip, originally released in 2013.

Flappy Bird》是一款由 Miniclip 製作的手機遊戲，最初於 2013 年發佈。

However, it was removed from the App Store and the Google Play Store in 2014 because the creator felt like it was too addictive.

不過，由於製作者認為這款遊戲太容易讓人上癮，它於 2014 年從 App Store 和 Google Play Store 下架。

Well, sorry Miniclip, but today we're going to be spreading your game a little bit.

好吧，對不起，Miniclip，但今天我們要把你的遊戲攤開一點。

I think the best way to do the screen is with a lamp display.

我認為做螢幕的最佳方法是使用燈管顯示屏。

I don't see any advantage to using pistons here.

我看不出在這裡使用活塞有什麼好處。

As far as how big it's going to be, I'm not really sure, so I'm just going to make a starter screen and we can always change the size later.

至於它有多大，我還不太確定，所以我只想做一個起始螢幕，以後我們可以隨時更改大小。

Okay, I just made one that's 16 lamps by 16 lamps.

好吧，我剛做了一個 16 盞燈乘 16 盞燈的。

To me, when I hear constantly falling, I think of a degrading circuit.

對我來說，當我聽到不斷下降的聲音時，我就會想到電路正在退化。

A degrading circuit would just lose value over time.

劣化電路只會隨著時間的推移而失去價值。

For example, you could have a comparator into another comparator like this.

例如，您可以讓一個比較器進入另一個比較器，就像這樣。

If you imagine that this line right here is the height of the bird, if you start it like this, you can see how the height naturally falls down.

如果你想象這條線就是小鳥的高度，像這樣開始，你就能看到高度是如何自然下降的。

Here, let me put some lamps so you can see it a little bit better.

來，我放幾盞燈，讓你看得更清楚一點。

You start like this and see how the gravity part of the bird.

像這樣開始，看看鳥的重力部分是怎樣的。

All right, so I played with the timings a little bit and as long as we're trying to make this game run in real time, I think this is probably a good speed.

好吧，我稍微調整了一下時間，只要我們想讓遊戲實時運行，我覺得這個速度應該不錯。

The one problem with this though is that right now, aesthetically, the bird is just a huge bar of lamps that gets shorter.

但這樣做的一個問題是，從美學角度來看，現在的小鳥只是一個變短的巨大燈條。

I'd rather have it just be like the top of the bar, so a single pixel.

我更希望它就像條形圖的頂部一樣，只有一個像素。

If we attach a red coder to this or a signal strength decoder, we can just get that top pixel.

如果我們在上面安裝一個紅色編碼器或信號強度解碼器，就能得到最上面的像素。

All right, I attached a red coder on the end of Now, if we send in a signal strength here, it's only going to light up one lamp associated with that signal strength.

現在，如果我們在這裡發送一個信號強度，它只會點亮與該信號強度相關的一個燈。

When I press this button, it's still going to give a signal strength of 15 and start to degrade, but now it's just a single lamp.

當我按下這個按鈕時，信號強度仍然是 15，然後開始衰減，但現在只有一個指示燈。

Our lamp started up there and it falls all the way down to the bottom just like it had gravity.

我們的燈從上面開始，一直落到下面，就像有重力一樣。

All right, so we've got a bird on the ground.

We can set it up to the ceiling and then it'll fall down, but how do we make it jump?

我們可以把它架到天花板上，然後它就會掉下來，但怎麼才能讓它跳起來呢？

Well, if we think about what a jump is, a jump is really just take the current height and add a value to it.

好吧，如果我們想想什麼是跳躍，跳躍其實就是把當前高度加上一個值。

Why don't we just take this signal strength, which again represents the height, add some value to it, and then plug it back in whenever we want to jump.

我們為什麼不把這個信號強度（同樣代表高度）加上一些值，然後在我們想跳轉的時候再把它插回去呢？

The way that we're going to add a value to the height is with a circuit like this.

我們將通過這樣的電路為高度添加數值。

This is the input signal strength right here, this is the output, and this is where you want to put the value that you want to add.

這裡是輸入信號強度，這裡是輸出信號強度，這裡是要添加值的位置。

What we're doing here is what I like to call a double inversion, where an inversion is taking 15 minus your current signal strength.

我們在這裡做的是我喜歡的 "雙重反轉"，反轉就是用 15 減去當前的信號強度。

We do it once right here because we're taking 15 minus whatever this signal strength is, and that's the output, and then we're doing it again over here. 15 minus 7 is 8.

我們在這裡做一次，因為我們用 15 減去信號強度，這就是輸出，然後在這裡再做一次。15 減 7 等於 8。

If you don't do anything special to it in between the two inversions, then it's just kind of a comparator.

如果在兩次反轉之間不做任何特殊處理，那麼它就只是一個比較器。

It goes in one signal strength, and it comes out the same signal strength, because inverting it once and then inverting it again puts it back to what it was.

輸入的信號強度相同，輸出的信號強度也相同，因為反相一次，再反相一次，就會恢復到原來的狀態。

But if we go over here and put some value here, that's going to subtract it from whatever it is in between the two inversions, and that actually adds it to the number.

但是，如果我們在這裡輸入一些數值，就會從兩個反轉之間的數值中減去它，這樣實際上就把它加到了數字中。

If you want a proof of this, I'll put it on the screen right now, but yeah, I mean this is just the way I remember it.

如果你想證明這一點，我現在就把它放到螢幕上，不過，我的意思是，這只是我記憶中的樣子。

The way to add to signal strength is just to subtract while it's inverted.

增加信號強度的方法就是在反轉時減去信號強度。

So if you jump height to be let's say 3, then you just grab a signal strength barrel with 3, and now whatever signal strength goes in here, it's going to add 3 to it and come out here.

是以，如果將高度設為 3，那麼你只需抓取一個信號強度為 3 的桶，現在無論什麼信號強度進入這裡，它都會加上 3，然後從這裡出來。

So for this example, we have 8 plus 3 is 11.

是以，在這個例子中，8 加 3 等於 11。

If I try something else, let's say 10 plus 3 is 13.

如果我試試別的，比方說 10 加 3 等於 13。

So now I just have to attach this to this, and we should have jumping.

是以，現在我只需把這個連接到這個上，我們就可以跳轉了。

讓我們試著生出一隻小鳥，然後跳起來。

Alright, I think it's time to put this bad boy onto the screen.

好了，我想是時候把這個壞小子搬上銀幕了。

To do that, I'm going to need a vertical red coder instead of a flat one like I have here, but I think I have a design for it.

為此，我需要一個垂直的紅色編碼器，而不是像這裡這樣的扁平編碼器，但我想我已經有了一個設計方案。

我的原理圖文件夾裡就有一個。

是以，這是一個垂直的紅色編碼器。

It does the exact same thing as the other one.

Whatever signal strength you put into the back here, it's just going to show whatever lamp that is.

無論你在後面輸入什麼信號強度，它都會顯示相應的燈號。

Okay, I took the vertical red coder, I attached it to this guy, and I put it behind the screen.

好了，我把垂直的紅色編碼器連接到這個傢伙上，然後把它放在螢幕後面。

It actually feels like Flappy Bird already.

實際上，它給人的感覺已經像《Flappy Bird》了。

Since we have pipes coming from the top and the bottom, you might think it's easiest to just generate like a random length pipe right here, and then another random length pipe right here, and that would look something like this.

由於我們的管道來自頂部和底部，你可能會認為最簡單的方法就是在這裡隨機生成一個長度的管道，然後在這裡隨機生成另一個長度的管道，看起來就像這樣。

But I think a better way to generate them would be to generate one giant line and then pick a random hole, right?

但我認為，生成它們的更好方法是生成一條巨線，然後隨機選擇一個洞，對嗎？

Because once you have this line, if you just pick a random hole, like say you pick here, there you go.

因為一旦你有了這條線，如果你隨便選一個洞，比如選這裡，就可以了。

To physically move the pipes across the screen, I think I'm just going to use a system like this.

要在螢幕上實際移動管道，我想我會使用這樣一個系統。

We just have an observer chain and then a bunch of observers coming off of that chain.

我們只是有一個觀察員鏈，然後再從這個鏈上分出一批觀察員。

Whenever you give it an update, it gives you a nice three-wide pulse across these lamps.

每當你對它進行更新時，它就會在這些燈具上提供一個漂亮的三寬脈衝。

Okay, I stacked it up a little bit and I simulated a little system to see what the pipes might look like.

好了，我把它疊起來，模擬了一個小系統，看看管道可能是什麼樣子。

我的意思是，這看起來很不錯。

My only concern is that this might be a little bit too fast.

我唯一擔心的是，這可能有點太快了。

I mean, these are moving pretty fast across the screen and considering our bird only falls that fast, I don't think it'll mix well with those pipes.

我的意思是，這些東西在螢幕上移動的速度非常快，考慮到我們的小鳥只能以這麼快的速度落下，我不認為它能和那些管道很好地混合在一起。

But I mean, at the same time, you can also just make the bird fall a little bit faster by making this clock a little bit shorter.

但我的意思是，與此同時，你也可以通過把這個時鐘縮短一點，讓小鳥落得更快一點。

This would, even if the bird was at the same pace and it was falling really fast, this, I don't think Flappy Bird is meant to be, meant to be this crazy.

即使小鳥以同樣的速度快速下落，我也不認為 "快樂小鳥 "會如此瘋狂。

At least not until you get to the later levels or whatever.

至少在進入後面的關卡或其他關卡之前不會。

So I'm going to have to think of a different system to move the pipes across.

是以，我必須想一個不同的系統來移動管道。

What if we put repeaters on the back of these?

如果我們在這些後面裝上中繼器呢？
