This time a pixelscroller in Actionscript3.
I hope you know Zelda from the good old SNES. Maybe you do not, but there are two worlds, the light- and the darkworld. As Link you are able to switch between these two worlds using a teleporter.
Now what about Flash and two worlds?
This is just a quick result of a bored evening but you can see what is possible. The world is 2048×2048 px large and has 128×128 tiles with a size of 16×16 px. This makes it easy to imagine what huge chunks of data Flash has to manage and I think the speed is ok. Of course the 640×480 px version could be faster.
I also made a test while working on the tile engine with a Mario-Level. The speed at 640×480 px was ok (!) so with Flash 8.5 you are able to build nice tile engines that run with a high framerate at 640×480 px.
Press your left mouse button to switch between both worlds.
By the way I found an old bug. I am not sure if it really is a bug but this is annoying since Flash5. You have two listeners. One for onKeyDown and one for onKeyUp. Now you have an array of boolean values which shows you if a key is pressed or not. Something like function onKeyDown( event: KeyboardEvent ): Void { isKeyDown[ event.keyCode ] = true; } and the same with false for onKeyUp. Now if you press two keys at the same time and you release one and then the other there won’t be any event for the second onKeyUp.
Mmm… oddly it doesn’t seem to load for me, the screen stays black. (Flash 8.5, OSX 10.4.3)
I read about the same problem with a Mac on other blogs. Don’t know why it doesn’t work for you…
