Hi guys,
I'm working on a Space Invaders testcase.
You know those barriers right? Where you can hide behind and shoot a hole through? That's what I want to achieve.
Is it possible to do a collisiondetection pixelwise? And make a series of pixels of that sprite transparent after collision?
I'm using Cocos2d by the way.
Cheers
I think I'll have to go with a custom MutableTexture2d for fast getting and setting of pixels:
http://www.cocos2d-iphone.org/forum/topic/2449
My idea is:
- First do a pixel perfect collision detection using the pixelAt function
- If there's a collision do a 'sprite merge' with one sprite being an impact-radius sprite and of course the barrier sprite using setPixelAt.
Hope that's going to work out (performance).
Any other thoughts on the subject are very welcome.
Cheers

1. This might be a stupid question, but does GarageBand allow me to compose music "from scratch"?
Kind of like asking "Does a piano allow you to compose music from scratch?" You can play anything you like in GB and record the notes and later look at them on a staff.
2. What's the difference between GarageBand and Logic Pro?
Apple has three products, GB, Logic Express, and Logic Pro.
All three use the same engiine but Logic exposes a much more complex user interface and also comes with many more software instruments.
Stay with garage band until you have some specific reason to upgrade to Logic. Logic will directly import your GB projects so you don't loose any work.
3. Do I need a keyboard or whatever in order to start composing on Mac?
You can used what Apple calls "musical typing" to play music on the computer "qwerty" keyboard. The asdf row acts like the white keys and the qwerty row like black keys. It is clumsy and slow but some people get good at it. Buy a "real" music keyboard and it will be much better. I think also you can mouse click on a picture of a music keyboard but that is just awful.
But you want to play drums. Why not get a MIDI Drum controller and play on a simulated rubber drum head. I know you can play drums on a keyboard but I'd bet it feels un-natural if you are a drummer
4. Currently I only have GarageBand (which comes bundled within iLife). I did a search on Google and apparently GarageBand Jam Pack 4 comes with percussion which includes taiko drums. I haven't been able to find any reviews or videos on this, so could anyone tell me how good it is?
Most of the instruments on jam pack are just "ok". Good enough for your own composing but not good enogh for profesional recording. But there are third party speccialized software instruments that work. Jam Packs are the best bang per buck because you get so many on the disc. but always there is something better.
This is one example of a 3rd party "plug-in" I think there are a few others. http://www.ninevoltaudio.com/products/taiko.html
Put use the jam pack first
EDIT: The link about says you need "Kontakt" (full version) to use it. That is getting expensive but if you need that quality then you need it.

just to clarify, i'm not asking for advice in if I should invest. I understand concerns that apple has hit an all time high, but I strongly believe it will only increase in the next year.
If anyone has any advice as to how I can do this that would be great.
Call your local discount broker's office- TD Ameritrade, eTrade and ask them if it's possible.

It may be a lack of scope or focus. For example, I almost started a "using Gmail with Mail.app" article, but, you know, Google maintains such an article. Why not link to that? There are several other guides out on the net from various sources. Do we re-author them?
What warrants creating a new guide and what does not?

You aren't going to find any Javascript to do that. You are going to need some coding on the server side. Somewhere you are going to need to run the SQL and pull the data from a database.
For example, I'm currently working on a project that has a Flex front end and uses Google App Engine on the back end. I have a servlet that can process images and serve them up. I am using Java on the App Engine side.
http://photography.jeffknox.com/photography/image?id=188005&s=300
The above image is pulled from the database, the watermark is added, the image is sized and sent to the browser. It isn't a trvial copy and past but you might want to start looking at whatever the back end server is running. Too many questions to provide a definitive answer.
(Note: The above image will eventually go away as the database is still in active development and this is a test image. Likewise the watermark is just a placeholder and will change.)

Full keyboards only have 88 keys, not 108.
There are many different smaller size keyboards available, 49, 61, etc.. Even very small ones. Just google the, lotsa choices. Don't bother getting a pressure sensitive keyboard unless you're already a proficient player.
If you're using Garageband, you can just use loops and not even bother with a keyboard.

Aladdin Systems, maker of StuffIt , one of the most-used Mac applications ever, changed its name to Allume Systems last month.
The long-standing www.aladdinsys.com web site is now redirected to www.allume.com. They still have the magic lamp logo and refer to themselves on the web and in e-mail as "Allume Systems (formerly Aladdin Systems)".
They changed in order to settle legal disagreements with Aladdin Knowledge Systems (www.ealaddin.com (http://www.ealaddin.com/) or www.aladdin.de ( http://www.aladdin.de/)), maker of dongles and other security products. I happen to use products of both companies, and I sometimes went to one web site when I meant the other. There was probably longstanding confusion between the companies (and maybe also with Aladdin Enterprises (www.aladdin.com/index2.html (http://www.aladdin.com/index2.html)), the original maker of Ghostscript).
Aladdin Systems must have had little choice but to make this change, because they are sacrificing a huge amount of name recognition.
I wonder why they picked "Allume" as their new name. And why not call themselves StuffIt after their most famous product, since they already have www.stuffit.com (http://www.stuffit.com/)?

Look in your book for exactly what you're supposed to use for #import. You may have made a mistake.
I'm not sure, but #import <Fraction.h> seems wrong to me. If Fraction.h were a system-provided class, it would be correct. But it's a developer-created class, so #import "Fraction.h" seems more sensible to me, and is what I've always used when referring to class headers I create.
Post your code.
No one with any programming experience would believe anyone (beginner or experienced) who says there are no compilation errors, unless the code has actually been compiled without errors. You may be right, but we need to see the evidence of the compiler.
Thanks! Your answer helped. So now I know that <**> are only for system provided classes. I used quotes for Fraction.h and it worked.
The example that I used had everything dumped in the main .m file along with the main function.

Get a gigabit switch. They're cheap. As well, many/most currently sold WiFi routers and cable modems/DSL routers have a built-in gigabyte switch.
To use the WiFi printer, the device that is printing does NOT have to connect to the WiFi router via WiFi. It can connect hard-wired. That means if the WiFi router has a gigabyte switch, the connection to other hard-wired devices will be gigabyte (assuming gigabyte capability in the other device.) So the WiFi speed is not an issue, except when printing. And the WiFi speed will be more than sufficient for printing. You'll also be able to print from both machines.
http://img94.imageshack.us/img94/3773/photoiw.jpg (http://img94.imageshack.us/i/photoiw.jpg/)
It's hooked up to my cable modem, the Mini and the router. Both the Mini and the router get external IPs, however the Mini is connected full speed, while you can't get more than 20% of the bandwidth through the router, doesn't matter whether you're connected via Ethernet or WiFi-n to it. I guess the Mini is somehow prioritized by the modem.
And no, I can't connect the router to the modem and the mini to the router - because this is a 110MBit/s DOCSIS3 connection and as stated, the router only has 100MBit/s ethernet ports. I could however connect the router to the Mini via the USB2.0 ethernet adapter intended for the MacBook Air, but I don't really want to dedicate any CPU to that at all.
Darwin: This is exactly what I wanted, and Ethernet was already on top of WiFi. Thanks.

What are some good Go clients/servers?
I play Go on occasion. Here's what I've played on/heard of:
Goban - A nice little native Mac program that you can play against GnuGo with, or analyze SDF files with. It might also work with some online servers.
DragonGoServer.net - You can play correspondence games online here, no client required other than a web browser. Some people even play fast games on it. This is what I played on when I played regularly. I haven't been active on there for a year or so, though.
Kiseido Go Server (http://www.gokgs.com/) - I played on here once or twice, but they had a java client back then. Looks like they have a downloadable client on their web page.
Actually, I'll just link you to the Sensei's Library wiki. They have -all- sorts of resources for the Go junkie. http://senseis.xmp.net/ In particular, you can check out their entry on Go Servers: http://senseis.xmp.net/?GoServers
Have fun and good luck! :)

I'll be at the Palo Alto Store by about 2PM with my copy from a nearby college bookstore that I'm getting for $69 before 2PM. That should put me near the front of the queue.
I don't know what you mean here. You're going to the Apple store with a copy of Leopard you already bought? Or do you mean you'll be near the front of the queue of people who will have the item in hand?
Pretty sure you have to buy a $129 copy to get the T-Shirt.
Well it does say on Apple's website that the "first 500 guests" will receive the T-shirt, and says nothing about requiring a purchase. Though, if MacMall doesn't ship it out on Thursday, I'll be cancelling the order with them and going to the store to buy it anyway. And if they do, I would still consider going to the store, and buying it and returning it just for the T-shirt. I'm a geek like that. ;)
Oh, you edited your post to answer mine, so I shall do the same ;)

it will sure fix it if the kernel panics were caused by overheating, which is likely, i would give it a shot, if that doesnt fix it then you know that the problem lies somewhere else!
do you know what I have to type in google to find which one I would need to buy? I dunno what the name of the product is... thank you.

I also have a job, two kids and not a lot of time to troubleshoot a problem if I mess up my iPad configuration.
