When I used cracked (I am sorry for it) 1.5.x version, I saw a camera function. Now, when I bought it, I didnt find this function. How to access it in 1.8?

It's the button at the top that looks like a camera. Go figure.

There isnt any. Maybe my camera is unsupported? (iMac, Mac OS 10.6)

Do you have 1.8 or 1.8.5? Even if the camera is unsupported, there should still be a button. I don't even have my camera connected and the button is still there.

1.8.5

And there's no camera button directly to the right of the options menu button (the one that looks like a hollow gear)?

I normally wouldn't help you, because you used a crack version, but here. It's the one circled in red. You have to have the menu expanded to see it, I think.

I used it a long time ago, I liked Algodoo and bought it. And, maybe its because of mac?

I'm pretty sure you just answered your own question. You need a webcam to use a webcam. How else will the image get to your computer, without the actual camera?

However, if you mean you just want something acting as a webcam, I think Manycam can do that, but you might want to check first.

You haven't heard of the magical software that makes a webcam spring out of your monitor? Jeez Jason, keep with the times...

I managed to construct a primitive webcam out of common household objects and a nearby cat.

Oh, that's why my webcam didn't work, I forgot the cat. D'oh!

Don't worry about it; it's a common rookie mistake.
