Flash 11 Platform Game Prototype

you can view an early prototype for a platform game I’m building with flash 11, away3d and box2d below. You can view the game in action here (Warming: there is no pre-loader). I’ve been surprised at the speed in which I’ve been able to put this together and because everything is xml driven once the initial level, characters and game objects have been implemented content generation is going to be a breeze. You can view the xml here. As stated above this is an early prototype, so there are plenty of things missing, for example the hero will probably stop walking when he isn’t moving ūüėČ and I’m sure most of what you see will change anyway, but just thought I’d share my...

integrate browser scrollbar with flash – part 2

After my last post on integrating the browser scrollbar with flash a friend of mine (Tim Keir) instantly pointed out that there is a small library called swffit which he said achieves a similar result. Don’t you just hate it when that happens! However while swffit is a great library (and I encourage you to check it out),¬†it achieves a somewhat different result than what I was trying to demonstrate. swffit basically sets the height of the swf to 100% as long as the browser height is greater than x, if the browser height is reduced below x then the flash movie’s height is set to x and a browser scrollbar appears. This is great for full-page flash movies when viewed on a small screen because the user will always be able to scroll down if there screen isn’t big enough. So obviously my explanation and example require a little reworking to clarify why you might want to implement something like this. So that’s what I’ve done.¬†This time round I’ve¬†abandoned the idea of creating an experience similar to an html page and focused on more of a ‘flashy’ example. Its still very basic, but it should give you a better impression of the possibilities. The second example can be viewed¬†here. This time there is also a scrollbar along the bottom of the window, as well as a 3d cube which replaces the checker panel. The side scrollbar controls the cube’s rotation around its¬†x axis and the bottom scrollbar moves around the cube on its y axis. also in¬†addition to this clicking and dragging anywhere on the flash content (or...

Integrate browser scrollbar with flash – part 1

Just a quick post to demonstrate how to integrate the browsers native scrollbar with a full-page flash movie. Why? Why not… People always go on about how flash and html/javascript work well together, so thought I’d try to create something new that’s flash/javacript related. Click here to view the example in action. Right clicking anywhere on the page will bring up the flash player context menu, so obviously this is a full-page flash movie. However where this differs from your traditional full-page flash movie is that it will add a native browser scrollbar if the checker box exceeds the height of the browser window. Once the scrollbar appears the user is able to drag the scrollbar up and down and it will adjust the flash content just as you would expect html content to scroll. So why is this a nice feature to have? Well the browser scrollbar is something everyone is familiar with. Everyone knows that when you see the scrollbar on the right hand side of the browser you can scroll the page. That’s not to say you can’t add additional interaction to the flash movie and update the scrollbar appropriately, I think its always nice to have a few different ways of navigating through a site, whether it be via the keyboard, or various mouse interactions. Obviously this is just a basic example, but you could really go to town with this. If I had the time I would love to create a Stage3D scene and use the scrollbar to move through it. You can grab the source here. Continue reading part...

.MPO to Anaglphic or Stereo Pair JPG

I recently bought the new Fujifilm FinePix W3, it a nutshell its a camera with stereoscopic lenses (see below) which means you can shoot 3d photography and hd footage. It doesn’t stop there though, on the back of the camera you have a 3.5-inch glasses free 3d display. Without a doubt the coolest gadget I’ve ever bought. One thing that surprised me was the format in which the W3 saves stereoscopic images, the file extension is called .mpo and I can’t say I’ve ever heard of it. I was expecting it would save as a stereo pair .jpg or .jps which would be easier to view and edit on a regular computer display. It turns out there are a few programs out there that will convert .mpo to .jpg, but not that many. So i decided to look into the possibility of converting in actionscript. Because the .mpo format is basically multiple jpgs saved within the one file it turned out to be pretty straight forward. Building on Thibault Imbert’s work on jpg decoding I simply wrote a few classes to parse the .mpo into separate jpg byteArrays and then output the result as a stereo pair or a anaglyphic...
