Hello everyone…
I need to make this C function to maxscript:
short ShortSwap( short s )
{
unsigned char b1, b2;
b1 = s & 255;
b2 = (s >> 8) & 255;
return (b1 << 8) + b2;
}
I don’t understand C++ but if you would write that in pseudocode then I might be able to help…
maybe you can use bitarray values to mimic bitshifting?
But this is only a guess to subscribe to this thread.

Well that’s my problem too, but I know a litle bit of c++.
I know that “<<” is a bitwise shift left operator and the “>>” is a bitwise shift right operator and maxscript have a bitwise function (bit.[font=Courier New]shift[/font]), but my problem is about that & operator. I don’t know what he does.
& should be bit.and
as && is a logical AND.

[size=2][color=white]Problem solved.
fn[/color][/size] ShortSwap s = (
b1 = bit.and s 255
b2 = bit.and (bit.shift s 8) 255
return ( (bit.shift 8 b1) + b2 )
)
Thanks Georg.
please tell me when to use this?
I googled it and it seems to be needed to write endian independent code.
Where could one use this in max?
regards,
Georg
I need to export the geometry of 3dsmax to a binary file format and for that format I need to flip the bytes. That’s why I need this.
thank you.
Georg
No, thank you for the big help Georg.
