利用Box2D+WCK賦予Flash物理特性 萬有引力
這已經是第五篇Box2D+WCK的介紹文章了，前面幾篇文章如果各位有注意應該會發現，所有範例的萬有引力都跟現在我們生活的環境一樣，物件像是被地心引力給吸引著都會往下方掉落，其實我們在使用這個模組的時候，也可以改變這樣的萬有引力，讓這些物件不要往下掉落而是往我們所指定的方向移動，馬老師在這邊大概製作了三種不同類型的萬有引力範例，分述如下：
1.容器型萬有引力：這個萬有引力是利用一個封閉的空間來繪製的。
大概的製作步驟如下：
我們可以在World元件中繪製一個如下圖的形狀：
接下來將他轉換成一個影片片段，在類別的部分輸入gravity.GravityCapsule的名稱，如下圖所示：
接下來把這個元件拖曳到World元件裡面就可以了。
2.放射狀萬有引力：這種萬有引力是以往內或往外放射狀的方式存在。
我們可以在World元件中繪製一個如下圖的形狀：
接下來將他轉換成一個影片片段，在類別的部分輸入gravity.GravityRadial的名稱，如下圖所示：
接下來把這個元件拖曳到World元件裡面就可以了。
3.正弦萬有引力：就是三角函數的sin。
我們可以在World元件中繪製一個如下圖的形狀：
接下來將他轉換成一個影片片段，在類別的部分輸入gravity.GravitySine的名稱，如下圖所示：
接下來把這個元件拖曳到World元件裡面就可以了。
同樣的也讓大家可以下載以上的三個範例檔，範例檔為CS5格式，下載後要重新設定來源路徑和元件庫路徑喔！希望這個範例對大家有所幫助，如果還有疑問，也可以在這邊回應唷～
Airbus exploring double-level airplane seat design
гей порно большой
If you’ve seen images of the infamous double-level airplane seat concept and thought “that’s never going to happen” — maybe think again.
Aviation start-up Chaise Longue, the brains behind the controversial dual-level seat, announced today it’s “exploring some early stage concepts” with aviation giant Airbus.
This collaboration with an aircraft manufacturing heavyweight is a significant step in this seat design’s journey from college student project to potential in-air reality.
Designer and Chaise Longue CEO Alejandro Nunez Vicente tells CNN Travel he’s thankful Airbus sees “the true potential of two-level seating.”
An Airbus representative confirmed to CNN Travel that “Chaise Longue is exploring some early stage concepts with Airbus on two-level seating solutions for Airbus commercial aircraft.”
The representative added that “given the nature of this early phase level,” Airbus preferred “not to further comment at this stage.”
The crux of Nunez Vicente’s Chaise Longue seat design is the removal of the overhead cabin to allow two levels of seats in a single aircraft cabin.
The idea is that travelers would have the option of booking the top row or the bottom row — and while the lower level might look less-than-appealing in photos, bottom passengers would be able to stretch out their legs and enjoy extra leg room. The top level is also designed to give “larger recline angles” and “leg-stretching possibility” than your average economy airplane seat, says Nunez Vicente.
Nunez Vicente initially developed the design for economy cabins before last year premiering a business class/first class iteration.
CNN Travel tested out early prototypes of both concepts and concluded that while the lower level has definite claustrophobia potential, the increased leg room could cancel out the potential cabin fever for some passengers.

How Nigeria’s biggest city became the world’s hottest winter party destination
casino bonus
It’s a world of endless parties and sleepless nights. A relentless celebration that turns West Africa – and especially Nigeria’s largest city, Lagos – into one of the hottest destinations on the continent, if not the planet, right in the middle of winter.
Detty December is a magical time between December and early January when diaspora communities and tourists flock to Ghana, Nigeria and South Africa for an unforgettable experience filled with flavourful food, soulful African music and sunshine.
Beach parties, festivals and top-tier performances fuel the energy, while fashion takes center stage, with everyone dressing to impress.
Nearly two-thirds of Nigeria’s population is under 25, according to the United Nations Population Fund, making this one of the world’s youngest countries.
Internationally renowned Afrobeats performers and foreign artists make surprise appearances. DJs take to the streets, blasting powerful beats from consoles mounted atop bright yellow minibuses.
At times it’s all-consuming. Good luck getting hair salon appointments, affordable air tickets or navigating Lagos’ already notorious traffic when the party crowds are in town.
Detty December (“detty” is a playful corruption of “dirty”) is a triumphant celebration of culture, music and good vibes that has evolved in recent years during the traditional holidays influx of diaspora returnees, which heightened in 2018 when Ghana ran a launched a successful “Year of Return” campaign actively encouraging people to visit their ancestral homelands.
It’s gathered pace over the past five years, gaining an international reputation, as IJGBs (“I Just Got Backs”) and their friends arrive in batches, eager to unwind and blow off steam after the fast-paced, hard-working year they’ve had overseas.
For many in the vast Nigerian diaspora, it is a deeply personal homecoming, a chance to reconnect with their heritage, traditions and families while immersing themselves in the lively energy of Nigerian life.
