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

It's, erm, insania. The gist of it being that the whip-wielding vampire-vanquishing adventure into androgyny, Castlevania: Symphony of the Night, is going to vanquish vampires and wield whips on Xbox Live Arcade this Wednesday (when else?). An 800 MS Point ($10) expenditure will net you both the original version of the game and another that boasts improved HD visuals and sound.

While there are some other factors the main one is simple supply and demand. The same reason why MBPs hold their value over non-mac notebooks.

Okay, I'm no newbie but I am stumped on this. Just got a new iPad 1. It came loaded with 3.2.2 (blow out pricing at Verizon). From all my reading, I can't jb this firm version. So, I dl'd the iPad 1,1 4.2.1.ipsw file so I could utilize the Greenp0is0n app (which, I gather 'used to' work on 3.2.2 but now requires 4.2.1). I shift-click (PC) to install that and Apple won't let me (natch, cuz it isn't 4.3.1). Since this is new, with unbreakable current firmware, I have no shsh blobs I can reference saved. So, changing the hostfile won't help me as there is nothing a cydia I can retrieve.
Question, in short, what do I need to do to jb this? :confused:
You have a very limited window, see this thread http://forums.macrumors.com/showthread.php?t=1124940
You need to run TinyUmbrella Now! Save your 4.3 blobs now...

Are you sure you played Lemmings on the Amiga? We'll forget Lemmings 3 though :cool: ... everyone else did!
No game I've ever played could I call perfect. There have been some close calls such as
Mario 64 & Super Mario World - Nintendo
Indiana Jones & Fates of Atlantis - LucasArts
but - there's always room for improvment.

I don't really know why research is needed for this, unless you don't know Python at all. If that is the case, you don't need to research how to do this in Python, you just need to research Python. Finding code online that does what you need is easy. However, i doubt somewhat seriously that you have a real-world problem requiring this, and you're simply desperate for a solution. Instead this sounds like an academic assignment/exercise/what-have-you.
If that is the case, then you want to learn something, not find the answer. That means you might need to learn:
What a palindrome is (you probably already know this)
How to write a loop in Python
How to manipulate numbers using Python (including exponentiation and division, perhaps taking logarithms)
OR
How to manipulate strings using Python (including getting a substring, string equality, or character equality and getting characters)
As an academic exercise i would try to write both approaches... treating the number as a number and approaching this with math and treating the number with a string and dealing with it that way.
I'm confident that you can google your way to what a palindrome is if you don't know, and the Python documentation is actually quite good:
http://www.python.org/doc/
Good luck. As you progress feel free to post code here telling us what you've tried, what the current errors are (or erroneous results), what you expect to happen, etc. We'll be glad to help you work it out, but it's better for everyone if we don't give you the answer.

I got some relief from a similar problem when I set my mail to check for new mail less often than I had previously set it. Seems some servers don't like it when you access too often. I'm at every 5 minutes now, with no problems. Maybe this would work for you?

hahah i just might do the overnight thing! thats taking a big risk of going that late to an apple store, might be at the back of the line LOL!!! most apple stores online are updating to reflect an 8am open on friday, so waiting for Canada's store to say that too :-) Maybe even a reserve as well...
I am 99.9% sure if you show up at an Apple Store at 6am you'll walk out with an iPhone 4 - even if they open at 8am.
Those that showed up at 7am to the Apple Stores during the iPad launch were able to get iPad's.
6am is a safe bet.

Perhaps it can be used in the Mac Mini Media and iMac lines. Future generations will be smaller for notebooks.

As much as the sarcasm was welcomed - he did ask for just the screen portion. I.E - without the stand. So that "really helpful website" wasn't too helpful.

I can't comment on the HD650 with a macbook pro personally, as I do not exactly have one. Of the few times I've tried it out, it was at a friend's and at local music stores. I'm an audio technica kind of guy, so I tend to stick to their products. I know the lower impedance audio techncia cans sound pretty good on my brother's macbook pro and my iMac via their intel hd integrated card and headphone jack.Well, thanks for the posts. I am a bit surprised how quiet this subform seems to be, I was hoping for a wider range of opinions. Or, do I just need a shower?

I used the V400 for a while. We didnt get a long to well. It was fine, the battery life was fine for me. Nothing un reasonable. 3-4 days is what I got. I seemed rather slow n sluggish at times. It also scratches very easier. Then my backlight died on it. ( Just one day went out.) I went into Cingular and they gave me a new one on the spot.
I was done with the phone though, and bought a V600 at the same time. (sold the new V400 on ebay) It much more durable IMO opinion.
I've since bought a V3.
All in all its a good phone. Nothing special IMO. but solid.So you would recomend the v600 over the v400 as far as battery life and quality?

BTW Macaholic, how did you get sooooo much folding power?!? And are you folding for Team MR?!?
Bought it or built it myself. A man has to have a hobby. ;) I fold with Team MacOS X. Calling all Mac folders. Please spread the SMP client news (http://forum.folding-community.org/viewtopic.php?t=16715&highlight=) far and wide. Oh, did I mention it is SPEEDY and worth your time?! Can you say NATIVE?! I thought so. Now GO! :D
