Waves.

Today we presented our work with the API Lab. Since not everyone was able to show up today I presented a bit more than I had prepared. I found out a bit of last minute that I was to present the introduction as well as Felicia’s example since she wasn’t able to come in. It went okay and I feel like I could get our point across. We presented our idea of prototyping with interactive movement and velocity to see changes in the users behavior towards for example loading screens of pending requests or downloads which might take a bit longer time. 

We had explored different ideas of how to use movement and velocity with this purpose, for example making a small “gaming environment” as I did and interactive clicks that changes the displayed image/environment of some kind. I feel like we worked nice together towards the same goal and the same prototyping idea. That is - to test out interactive movement in a loading screen environment. It was a bit difficult at times to gather the group since we have had a lot of other stuff going on - for example with project 1 etc. The API lab has unfortunately got a bit into the background and we’ve worked with it when we’ve felt like we’ve had the time to do it. I also found the assignment a little bit difficult and confusing at times - it wasn’t really clear in the beginning that we were supposed to use it for prototyping purposes and have that in mind. Fortunately we as a group could use our work and extended examples to explain what purposes they had in a prototyping environment. It was also a bit difficult to get into the API since we didn’t have a lot of programming experience and getting thrown into it is both good and bad. If we could get more isolated time with only this it might have turned out to be easier than I experienced it to be. A shattered mind is not ideal for learning new things and diving deeper into a specific library.

## 所感

豊富な実績が物語るように2Dゲーム開発するライブラリとして洗練されている。（想像以上に機能が多かった）

比較的素直なAPIでドキュメントも豊富なので開発中に極端に困ることはたぶんない。

また、良くも悪くもライブラリなのでJavaScriptが得意な人が書くとすごく早く出来上がりそう.(逆にゲームエンジンでの開発に慣れている人は立ち上がりに時間がかかるだろう)

懸念点

ALTJSや静的型付けの型定義の情報が少なくコミュニティでもあまり実績が無いのではないかと思った。

One week after starting Video Jigsaw Puzzle: added music and SFX, responsive canvas, single-button controls, and a new video.

I’ve slightly broaden the spectrum of topics raised on my blog. I want to write about everything I’m coding, so let the new category - #javascript - say hello world. 

I’ve recently heard about JS13kGames Competition and i’m really excited and motivated to submit the entry. In the meantime our local gamedev group is organising a monthly meeting with microjam - tiny game competion. This month’s theme is MURDER. I think it’s nice warmup.

I know nothing about game development, but I can tell some story in simple, point and click way. Framework I’ve picked to do this is PixiJS.
