[Flash8]scrollrect Scroller

Here is my example of scrolling tiles:

well, the imageshack scales the swf so you better download it and run it at 100% on your computer to see real speed :)

Fla is attached.

The way it works:
*there is tileset image in the library (1 gif with all tiles on it)
*random tiles are then chosen from there and drawn on myBmp bitmapData
*myBmp is 640x640 px
*tiles mc is created and 400x300 px scrollRect applied to it
*bitmap is drawn into tiles.bmp mc
*tiles.bmp mc is scrolled

fps is set to 32 in Flash

This uses same engine, but has 3 layers and dropshadow applied to 2 top layers:

very nice tony, running silky smooth and hey hey, that shadows give it a sweet depth feel =)
would be cool if you post the code and explanation so we can develop a best of scroller here =)

The fla.

I know what you mean, but the reason I was gonna keep the single tiles/frame in MCs is so that they can still have/inherit prototype tile propreties that might be passed on from an XML map file or a 2d array......things like whether a tile is walkable or not, or whatever else other costum propreties a particular tile template might have......not sure yet if that data can be attached straight to a bmp tile itself.....that's why I thought it would be still worth keeping bmps in MCs.....

just thinking out loud....maybe I'm wrong

I noticed the flickering in scroll too, but I havent found a way to avoid it yet. Looks like Flash cant draw whole bitmap in 1 go. If anyone knows good way, please tell :)

hmm...yeah I was thinking about that.....I want to keep your herarchy/organization as much as possible since I like the way you set it up....with the images/frames in single MCs define by prototype templates inside a main container....yet using some of the new methods to speed it up....

so I was thinking when the building level routine runs, use the bmpAttach method to attach the bmp straight from the lib to the tile MC, set that tile MC to bmp cache true (each one of the tiles in game) and then use the scrollRect to scroll the entire level container MC w/ all the tiles in it.....all at once w/out tile moving.....
and by doing that...still maintaining separate tile MCs there wouldn't be the limit in running in the size image limit for the bmpData...which I think they say it's 2880 pix.....

anyway just some thoughts I'm throwing out there.....I still need to test it...please correct me if you see something wrong or a better/more efficient way of doing it :-)

Indeed. Although it doesn't leave much room for interactive environments.

Even before seeing the code for this, I'm formulating an idea to combine this technique with something similar to strilles obj scroller to create some sort of super engine ;D I've already combined the obj scroller with a tile engine to create pretty swifty engines with lots of interactive objects in a large screen size, I can only imagine this would speed it up considerably.

I'm curious how it would work with alpha channels in the bitmaps so it would be possible to create a few levels of paralax using this.

Parallax, alpha, 256x256 tiles, no huge memory usage only related to screen size and tileset, scroll optimized...

erixon.. That seems to be way faster than the last time I looked at that demo. Either I'm stupid, or it's crazy fast now. Great job, sir!

Wow!! This Flash 8 is really getting popular around here. I wonder what new games we migh start seeing on the web? The possibilities are endless. I have all sorts of ideas for original games, but can't get to them all. Good luck on the Super Engine, tomsamson. Thanks to flash developers like yourself, we might just see huge games around here.

I wonder how fast my engine would run on that thing. Is there anyway to convert the flash 7 swf to flash 8 without having to get the program.

http://e.1asphost.com/andross88/MainGame.html

The game runs smoothly, but when I have 3 layers, its starts to slow down. So there would probably be no way for me to add enemies without the cpu going above 100, darn!. I want to test this with bitMapConverter in Flash 8 and see how much cpu resources it uses. my thanks for any help you can give.

nope, you're right!!...it is MUCH faster then when I looked at it a while back!!....also far faster/less staggering......very nice, Erixon.

can you tell us your method?..did you just use scrollRect?...also your engine doesn't seem to have flickering as some other ones seem to have.....was curious on how you got it so fast/smooth.....
nice work..


paul.

What can be tricky about test is that its best performance if CPU is at zero when starting, otherwise the FPS can decrease or CPU showing much more. So there is no big optimize since last time.

Its no secrets there really. Its 3 bitmapdata layers of 640x480 and when scrolling top layer I first scroll the whole area in one go and then fill out with tiles only where its needed at the sides. Middle layer is just wrapped around with a 640x480-image.
