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

Hi,
I've got a 2007 Aluminium iMac and I've noticed these last few weeks that it is spinning the beach ball a bit more than before and has to have a little think about things when I ask it to do something from time to time.
Time for a spring clean I think. :D
So, can anyone point a tech-savvy person towards some good articles or forum threads on how to get my Mac operating again as it should?
My machine was running Tiger when I bought it and was upgraded to Leopard then Snow Leopard. I've never done a reinstall and to be honest I was hoping I wouldn't have to. I'm 100% comfortable with messing with files, folders, plists and pretty much anything else on the Mac. If I'm honest I'm just looking for a cheat sheet for regaining performance on my machine without having to figure it out for myself... :o
Thanks in advance for any help,
Craig.

Bill Gates! Maybe you guys are too young to remember that. I thought it was the end of Apple, or at least the end of the Apple I knew and loved.
Whew, glad it turned out ok.

Isn't there a set amount of levels you can define?

OK I see the problem with Netflix, Microsoft not support PPC in Silverlight (well at least for the Macs), obviously the processor in the XBox is a tad different..

Thanks, Shagrat! I hadn't heard of that site, it looks like it could be very useful! :cool:
Great site, not unlike this one:- a lot of people who seem to enjoy a good barney every once in a while. Some N00bs, some real old hands, a good mix!
Been going there for a while. :D

What will you be using it for? I always suggest the Mac mini as the "switcher machine." But a Power Mac G4 will also be nice, especially since it is easy to upgrade.

You can't just turn it on..........then continually move the mouse around and around and around and around?
To stop it coming on?
nope that doesnt work either

Screenaid should be in the Hall of Shame.. Maybe yours was a beginners luck purchase but keep ordering and they'll get you. Google screenaid before you order anything. Several of my colleagues in the industry have blacklisted them

I would recommend to hold off any GPU purchases until Lion is released.

If they do announce, and release, at WWDC anyone buying a MBP within a month or two before may also get a discounted price on Lion.

I'm getting a PowerMac sometime soon and want to add a second hard drive pretty much straight away.
I'm looking at two on eBuyer that are priced well but just wondered if anyone had any advice.
Ones I'm looking at are:
Western Digital WD2500JD 250Gb 8mb Cache 7200rpm Serial ATA
or
Maxtor 6L250S0 Diamondmax 10 250GB 7200rpm Serial ATA150 16mb Cache
Thanks
Steve

focus on the eyes or some part of the face and then reposition. sometimes it comes out the way i want
I would suggest this could be the problem: when you reposition you are probably altering the distance between the lens and the subject somewhat.

What's everyone's SSD preferred SSD these days? I've got a 2010 MBP, so the Vertex 3 is not a good choice (expensive and less performant on a 3gbps connection), and I'm afraid of getting the junk version of the Vertex 2.
I've heard good things about OWC, but I have a bunch of Amazon gift certificates ($260 worth), so they're unfortunately not an option. (The only 240GB I could find on there was from one seller I've never heard of, memoryc -- no thanks.)
I'd like to get over 200GB if the price is right.

I haven't have any problems burning AAC to CD.
Here is a link to a discussion of AAC issues. Hopefully your answer is there (if you've not already seen this website).
Good luck.
