呢首係我第一首公開發放嘅歌, 歌名係"呢首歌嘅歌詞好奇怪". 首歌係關於呢首歌同埋佢嘅歌詞有幾咁唔掂嘅.
Behold my first song ever released publicly: "The Lyrics of This Song are Weird". This song is about the suckiness of the song and its lyrics.
首歌係我自己一個人整嘅(包括把聲同段片). 整左超過一個月. 如果你鐘意嘅話, 麻煩幫段片俾個like, subscribe個Youtube channel同埋share下俾你D friend. 如果呢首歌嘅反應良好, 我響未來將會整多D類似嘅歌. 多謝支持! :)
I made the song (including the vocal and the video) on my own. It took me more than a month to produce it. If you enjoyed the song, please give the video a like, subscribe to my Youtube channel and share it with others. If the reception of this song is good, I'll spend more time to compose similar songs in the future. Thank you very much! :)
我原本係為左整game而學整音樂嘅. 直至到幾年前, 我大概每一年就整一首廣東話歌. 呢首係我整嘅第三首歌. 之前果兩首太差, 所以我冇放到出來. 呢首我覺得唔算好好, 但係都算係咁啦. 所以我就決定放出來喇.
I learned music composition for game development. Since a few years ago, I compose Cantonese songs approximately once a year. This song is the third song that I've made. I didn't release the previous two songs because the quality were too bad. This one isn't good. It isn't that bad either. That's why I decided to release it.
呢個project總共用左8個軟件. 包括LMMS, Audacity, ProjectM, SimpleScreenRecorder, Inkscape, Spriter Pro, Aegisub同FFmpeg. 除左Spriter Pro之外, 其他都係免費嘅開源的軟件.
In total, 8 software applications were used for this project. They are LMMS, Audacity, ProjectM, SimpleScreenRecorder, Inkscape, Spriter Pro, Aegisub and FFmpeg. Except Spriter Pro, all of them are FOSS software.
This music was composed with LMMS. It's a music composition software designed for making music from scratch. I had briefly contributed to its development a few years ago. The voice was recorded and processed using Audacity. Some audio engineering was performed for the vocal track.
The procedure of composing this song is shown below:
我無正式學過作曲. 如果我用錯D專有名詞嘅話, 麻煩同我講聲. 我會更正. 另外, 以上步驟唔係唯一嘅作曲嘅方法. 以前我都用過其他方法作曲. 呢D步驟只係想解釋返我點整呢首出來嘅姐.
I haven't formally learned music composition. If I have used the wordings above incorrectly, do tell me. I will fix them. Please notice that it is not the universal solution of music production. I have tried out other approaches in my other songs. The steps above is just what I did for making this specific song.
Here's a screenshot of the song being edited in LMMS:
作廣東話歌同其他語言嘅歌有一個好大嘅分別. 就係要啱音. 我地有成6個音, 要對返個melody其實都有D難度. 仲要整到個歌詞嘅意思都要啱, 難上加難. 所以我作作下就卡死左喇!
Since Cantonese is a tonal language, I have to match the pitch of the melody notes with the tone of the Cantonese characters. Therefore, it's very tough to compose a Cantonese song as it's difficult to find the right word that has both the correct tone and the correct meaning. I was stuck in the midway while I was writing the lyrics.
Therefore, I had developed a tool to do this for me. The tool was written in Python. By using three Chinese word databases that I found on the internet, combined with the tone of the word suggested by Chinese Character Database: With Word-formations (which I had further modified manually because some of the tones were changed in the modern Cantonese we're using today), a list of words with matching tones is generated:
由上面嘅cap圖可以見到, 呢個工具可以列出個database嘅啱音嘅字(但係有小量錯誤). 例如我打240, 就可以搵到同"240"同音嘅字. 包括"亂晒籠, 垃圾蟲, 定晒形, 未夠喉, 滑鐵廬, 落晒形, 鼻涕蟲".
As shown on the screenshot above, the tool lists out all matching words that it found (with some minor errors). For example, if I type "240" (二四零), the first character of the word has to match the tone of 二, the second character must match 四, and the third character must match 零. The filtered result of the words is displayed, which includes "亂晒籠, 垃圾蟲, 定晒形, 未夠喉, 滑鐵廬, 落晒形, 鼻涕蟲" in the Chinese word database of Cantonese.
個工具仲可以俾你揀database. 目前個工具有廣東話, 大陸普通話, 同埋台灣國語嘅詞語嘅database. 雖然唔係所有歌詞都係用呢個工具作嘅, 但係呢個工具用來做brainstorming同埋搵D啱音嘅四字成語真係無得輸. 我以後應該都會繼續用呢個工具來填詞.
Database selection is also supported. The current version of this tool supports Cantonese, Chinese and Taiwan-style Chinese. This tool helped a lot while I was writing the lyrics for this song. Although I did not exclusively use this tool for writing all of the lyrics, it was very useful for brainstorming and finding Four-characters Chinese Idioms that match the tone that I want. I will probably continue to use this tool for my future songs.
不過好可惜, 我唔清楚部分database嘅使用條款. 所以我係唔可以放呢個工具出來嘅. 同大家講返聲唔好意思先.
Unfortunately, due to the unknown license of some Chinese words databases, I could not release this tool publicly. I'm sorry about that.
填完詞就用Audacity錄音同改音. 下面幅圖係我改音嘅過程. 只要複製highlight左果part就可以延長隻字個音長. Delete左果part就可以縮短隻字個音長. 呢個步驟不停重複, 直至做到把聲同首歌同步為止.
After the voice was recorded according to the lyrics written, Audacity were used for audio engineering. The image below shows how did I change the length of the Cantonese character that I had sung. By duplicating the highlighted part, the duration of that character is extended. Conversely, by deleting that part, the duration is reduced. This process was repeated for synchronizing my voice with the melody.
之後Audacity整出來嘅track會放返入LMMS裏面. 最後首歌係用LMMS generate出來嘅.
After that, the vocal track generated by Audacity was imported into the LMMS project. Finally, the song was generated by LMMS.
After the completion of the song itself, a video for this song was produced.
The audio visualizer software used in the video used was ProjectM. It is a real time audio visualizer. The visualization were recorded using SimpleScreenRecorder, which supports recording OpenGL output of any program. Compared with software-based recording method, recording the OpenGL output is much more efficient. Therefore, the output video is almost lag-free.
The image of the banner was created using Inkscape. After that, it was animated using Spriter Pro. Image sequences of the animation were generated. The subtitles editor used for the video of this project was Aegisub. With this software, a subtitles file were generated. An extra image were drawn with Inkscape for the end scene that asks the viewer to subscribe my channel. Finally, the audio outputted by LMMS, the visualization of the audio, the banner image sequence and the subtitles were combined by using FFmpeg. That's it!
我係作曲新手. 呢首個我花左好多工夫, 整左成超過一個月. 如果你鐘意嘅話, 麻煩幫忙share一下. 如果你地鐘意, 我日後會整多D呢類嘅歌. 多謝支持!
I'm rather new in song production. More than a month of work was spent on producing this song. If you enjoyed it, please take a moment to share it. Similar songs will be produced if the reception of this one is good. Thank you very much! :)
除此之外, 我都歡迎未來合作. 如果你有興趣, 可以send封email俾我架(email見網頁頂部)!
In addition, future collaboration is welcomed. Feel free to drop me a line by using the email address on this website.
This year, I've developed the game E. M. Wave Jammer. It is the world's first telephone game in Global Game Jam, which is playable by dialing a telephone number.
I FUBAR'd in last year's game jam. Fortunately, I did much better this year.
This game is for entertainment only, no political message intended.
For Hong Kong SAR phone numbers, dial 54839953. For non-Hong Kong SAR phone numbers, dial +85254839953 with skype. We do not accept international non-skype calls to save our operational cost. This game has Cantonese(Press 1), Mandarin(Press 2) and English(Press 3) version. Please notice that this phone number is temporary. It will be changed after I've finished setting up my phonesite.
The game happens in Japan during Cold War era. In the game, North Korea is using advance electromagnetic waves technology for sending signals to Cuba. They are plotting to attack Japan. In the game, the player plays as the role of the commander of telecommunication department. The player is responsible for jamming the signals between them.
For the ease of command, Japan is divided into 6 zones. The electromagnetic waves from North Korea will propagate via zone 1, zone 2, zone 3, zone 4, zone 5, zone 6, all the way to Cuba.
The player is required to use limited amount of electricity to build jammers. Electricity are consumed for building the jammers. No electricity is required to operate the jammers. The more electricity you spend to build a jammer, the more powerful it is. For example, a 5W jammer can attenuate the signal by 5W.
The remaining non-attenuated signal will become military information end up on enemy's hand. When the information level reaches 100%, you lose. The information level is increased by the Wattage of signal received divided by the Wattage of signal sent. There is no way to reduce the information level.
The player starts with 20W of electricity. To generate electricity, generators have to be built. They generate electricity when signal pass thru its zone. For example, a 5W generator will cost 5W to build, and generates 5W of electricity.
Each zone can only have one structure(e.g jammer, generator). New structure building on a zone with existing structure will demolish the existing one. Structures cannot be sold.
After wave 6, there will be Accelerated E.M. Wave signal. It is able to bypass Zone 2, 4, 6. It is sent via Zone 1, 3, 5 to Cuba.
After wave 11, there will be Narrow-band E.M. Wave signal, which includes low frequency E.M. Wave Signal and high frequency E.M. Wave Signal. Ordinary jammers are half as effective against these signal compared with other signals. Therefore, the player is able to build LF Jammers and HF Jammers to defend against these signals. A 10W LF Jammer can attenuate LF Signal by 20W, Ordinary Signal by 5W, and cannot attenuate HF signal. A 10W HF Jammer can attenuate HF Signal by 20W, Ordinary Signal by 5W, and cannot attenuate LF signal.
After wave 16, there will be E.M. Wave from Cuba to North Korea, which propagates via Zone 6, 5, 4, 3, 2, 1 to North Korea. Accelerated E.M. Wave from Cuba propagates via Zone 6, 4, 2 to North Korea.
After wave 21, there will be FM Signal. FM Signals is immune to Ordinary Jammers. It makes non-LF, non-HF FM waves very troublesome to be dealt with because they couldn't be attenuated by ordinary jammers. Yet, HF and LF jammers are only half as efficient to deal with non-LF, non-HF waves.
Before the Jam, I've developed the hardware Dinbo Prototype B as well as its library libdinbo. I've also made a template for developing any telephone system based on this library.
In addition of the telephone system, I have also practiced using LMMS, Labchrip, Audacity, SoX, just all of the software that I planned to use. I also planned to practice Aegisub for making video subtitles. Unfortunately, I didn't have enough time and the Jam day had come. :(
Just like the last year, the 48 hours game jam spanned across three days.
In the first day, I've arrived at the venue, before the event started, I've found a bug on the library of Dinbo Prototype B that made it failed to detect DTMF touch keys properly. Fortunately, I fixed it right before it started.
After that, I've listened to the briefing. After the theme Waves was announced, I came up with this game design quickly. Since I was working solo in this jam, this process went way quicker than the jam of previous year. :)
Here is a photo of my game design document. As you see below, it is only one A4 page. It is poorly-organized because I'm the only intended audience of this document. :P
Some of the features are strike'd out at the design stage because I foresaw that it couldn't be completed within 48 hours.
Here is a photo taken from day 1 of the event. Sorry for phone camera quality:
There were many jammers in our Jam site, and the Hong Kong SAR was the 8th largest out of 700+ jam sites all over the world in 2017!
With the experience of last year, I won't sleep on-site because I couldn't. At the end of the day, I went to home and took a rest.
Although I slept much better than last year, I still didn't sleep enough. Therefore, I woke up late. I started programming. Feeling dizzy, I took a nap after an hour of development. Then I woke up again and continue. To save some traveling time, I decide to jam at home this day because I was solo and I didn't need to go to the site to collaborate with my teammates.
With software emulation feature of the libdinbo, I was able to develop the game without dialing the phone number. It saved me some cost of calling the number.
With existing code base, the development went smoothly. I managed to implement the game play. After midnight, I started translating the game into Mandarin as well as English. I have also synthesized and recorded some sfx. Originally I also planned to make music and recording the Cantonese voice myself. Considered that I need to prepare for the presentation, I decided to drop these features and went to bed. All of the development works ended here. However, I still haven't deployed it on the Dinbo Prototype B hardware.
I (almost) dedicated this day for preparing for the presentation. I decided to prepare for the presentation before deploying it to the hardware. That is because the deadline of submitting the presentation was very tight. And preparing presentation before the deployment can buy me a bit extra time.
I started with recording the gameplay audio using the voice log function of the libdinbo in its software emulation mode. It went quite well and I've recorded a 9 minutes audio. I had cut down the audio to 4.5 minutes.
Then I asked the volunteers about the time limit of presentation. Turned out that each team would only be given two minutes to present their game. Well, I thought that I had 5~10 minutes. :/
After that, I further cut down the audio to 1.5 minutes. Even the gameplay instruction were removed.
So how did I explain the gameplay? Simple. I used Libreoffice Impress to make some presentation slides to visualize the game play frame by frame. Then I played the gameplay audio and used vokoscreen record the voice and the presentation slides. I clicks as I record and play the gameplay audio. After that, I used ffmpeg to trim beginning and the end of the video. Then convert the video format to webm. Here is the demonstration video in Cantonese.
After that, I prepared another powerpoint file. I planned to use the powerpoint before playing the demonstration video.
Everything went well, except that the deadline was very tight. I had to do everything I said above within like 3~4 hours. Then I uploaded my video to the website of Global Game Jam and sent the powerpoint to the staffs. After that, I have deployed my program to the Dinbo Prototype B hardware.
Here is the presentation session(the guy who is presenting in the photo is not me):
It didn't went very well when it was my turn. I thought that I could access a presenter's mouse so that I could show my powerpoint with animation. I thought that I could click the powerpoint myself. Unfortunately, the presenter's mouse wasn't working somehow. Then the staff of my jam site just random clicked his mouse, causing the slides shown up earlier than it was supposed to be shown. After that, the staff was trying to click on the gameplay demonstration video link inside the last slide of my powerpoint. But he forgot to enter presentation mode and couldn't click on the link. It looked very bad for the audience. :/
Nevertheless, the gameplay video was found to be funny by many fellow jammers. I enjoyed their laugh and applause at the end, and I earned a certificate of participation. :)
After that, I have introduced my final year project to my fellow jammers. Then I have interviewed some of them about my project. That is helpful for me to improve my final year project. :)
Finally, it was the closing ceremony of the event. As I have expected, I got no award because I'm solo. Apparently the sponsors of our site is reluctant to give out awards to solo teams. :P
Anyway, I have completed the game during the 48 hours. I have proven that libdinbo is working and I have shown my final year project to others. It is a great success compared with the previous jam.
After the jam, I have talked about the event with people from other jam sites via the Internet. Someone who joined the site of Tokyo University of Technology shared an interesting photo of the site(photo used with permission by the copyright holder of the photo):
Apparently the jammers in Tokyo University of Technology site had more fun than we do. Instead of giving out awards to well-performing teams, they had a pizza party! And the award was the game itself that the jammers developed. It is a better match to the sprite of Game Jam.
I'm performing much better in this game jam than the last one. And this year is much more fun for me. Here is what went well:
Overall, The Jam of this year went pretty well. And it was a quite memorable experience. :)
The Game Jam of this year is very special for me. It has some strategical value. As you may have noticed in my previous blogpost, Dinbo Prototype B will be a successor of the existing telephone system, Dinbo Prototype A. Dinbo Prototype B will be used for the following purposes:
This game jam helps improving the code base for Dinbo Prototype B, particularly, the internationalization functionality of the code base was enhanced during the jam. In addition, it's also a good way to test whether the entire system works. If a game can be developed for this system, then it would definitely be possible for me to develop my final year project using the same system.
That says, my mission of Global Game Jam 2017 is accomplished. Now I got to work on my final year project as well as my phonesite. :D

Sorry for not updating for a while guys.
Spent almost $100 on hardware and stuffs, worked for more than a month, Whack-a-mole over telephone is finally completed!
各位! 好耐無打廣東話嘅blostpost. 耗資陸佰港元. 動工參拾陸夜. 小弟嘅電話扑傻瓜終於搞掂喇!
Behold the gameplay(Cantonese with English subtitle)!
The gameplay is simple. First, dial the number 5517 6408 in Hong Kong(does not accept international call, Cantonese only). Then, when you hear certain sound, you'll have to press certain key. The sounds and the keys are randomly generated. If you press the correct one, you get a score. When it reaches the threshold, the difficulty will be increased as shown below:
Level 1: Score requirement: 0; Three random animal sounds. Each requires the player to press a key.
Level 2: Score requirement: 10; Three additional random synth'd wave sounds. Each requires the player to press a key.
Level 3: Score requirement: 30; Three additional random voice of numbers. Each requires the player to press another key that is usually inconsistent with the number that the player have heard.
Level 4: Score requirement: 60; After this level, the player has to press certain key for every 5 sounds, regardless what is the sound that the player has heard.
Level 5: Score requirement: 100; Upon hearing any of 5 random sounds, the players has to press a key. Upon hearing another 5 random sounds, the players has to press another key. Upon hearing yet another 3 random sounds, the player has to press yet another key.
遊戲玩法好簡單. 首先打5517 6408(唔收國際電話, 唔收133電話), 跟住佢就會叫你聽到某D聲就要撳某D制. D聲同D制係隨機嘅. 撳啱加分. 夠分就LEVEL UP:
LEVEL 1: 所需分數: 0; 三個隨機動物聲. 每個聲要撳一粒制.
LEVEL 2: 所需分數: 10; 三個隨機電腦合成聲. 每個聲要撳一粒制.
LEVEL 3: 所需分數: 30; 三個隨機數字聲. 每個聲要撳一粒制, 而嗰粒制通常唔係你聽到嗰個數字嘅聲.
LEVEL 4: 所需分數: 60; 每聽到五個聲就要撳某一粒制.
LEVEL 5: 所需分數: 100; 聽到某五種聲要撳一粒制. 聽到另外某五種聲要撳另一粒制. 聽到另外某三種聲又要撳另一粒制.
If you press the wrong key, or if you're too slow, then you lose. If your score is the highest among everyone else, the score will be recorded.
如果你撳錯制或者撳得太慢就會輸. 如果你嘅分數係最高嘅話, 個分將會被記錄.
Alright! That's it for the first part of the blogpost. The second part will be about the technical details of this project. See you! :)
Previously, I've released the web version of Poopie: Making Kim Jong Un Cry.
Today, I bring Poopie to Google Play! Behold feature graphic for the listing:
Let's make Kim cry. Go pooping with your Android phone today!
Hey guys! I've just released a new game. Poopie: Making Kim Jong Un Cry!
It is an enhanced version of my Ludum Dare 33 Entry.
The graphic isn't very good. But it's already a big improvement compared with its preceder. Well, my art indeed sucks. But it's getting improved over time. :D So don't complain about it. :P
A: Win the game to figure it out! :D
