Erm, your link to the Raycaster is broken, pity as I’d love to see it.

See http://www.visualharmonics.co.uk for a grand compilation of AS2/3 optimisation tips.

NOOOO!!! Why can’t I write a textured raycaster in Flash that runs more than 15 fps?! I might just kill myself Q_Q.

strange… i’ve installed flash player 8.5 for IE and FF as well and all I can see is cyan background, the same with other as3 demos.

Very impressive andre. Think you could speed up the whole thing alot more by adding fog maybe ?

andre you should write a book about all this, im sure it would sell, and its the only way the rest of us have a chance of catching up.

Impressive Andre !!
Is bitshifting really faster in AS3 because in AS2 there’s no real difference :S

About your types Array, did you think about creating a List? I mean it cans be compute like a structure owning a reference to the next node and a int value.
Don’t think it can be faster, but you can give it a try ;)

@bitwize:

Unfortunatley reading ByteArrays is much slower than reading from an Array.

What I mean is an Array, where all entries are typed to ‘int’. In Java, most grafic application read the pixels and stores them to a char[] Array. It is very fast to read an entry from.

Brilliant work Andre.

“What I’m really missing is a typed Array with simple bytes to write faster code, just reading RGB values. I have the feeling, that the getPixel method is too slow.”

hmm. if i’m understanding correctly, does this help?

BitmapData.getPixels()

“No, longer do you have to loop through every pixel in a bitmap, one at a time with getPixel… This method returns a ByteArray containing the hexadecimal color value of each of the pixels in the specified rectangular region of a bitmap.”

Brilliant stuff! When I ran the SWF directly as fullscreen 1024×768, I still had more than 30 fps!
