Title: The Null Value
Post by: abdalrahman9 on July 20, 2015, 03:40:49 am

Hello there, i am having some problems representing a null value in maxscript and even in 010 editor. I have tried the ctrl 2 and alt 00 but with no avail. I was not sure if there was a special way to do this or if i had to do it through hex. The reason is because i am currently making an exporter in 3ds max.

I am not sure, i have pressed the "" and the "0" keys together and separately but nothing works. I am still new at programming in maxscript.

Uh, there isn't any special supposed to happen. The sequence is an escape sequence in strings that represents a zero byte (0x00). "foobar" is 'f', 'o', 'o', 0x00, 'b', 'a', 'r'.

Though, the better question to ask here, instead of answering, is: What are you trying to do?

I didn't really want to share but i am attempting to create my own wmo exporter for learning purposes. As mirror machine is limited, i wanted to try this to create better wmo's and such. But this is really early and i am not sure what might happen in the future. So i am sure you know that there are many empty bytes in wmo as i was trying to recreate that in maxscript though i have been having some problems.

I am pretty sure you think i am dumb but  from i understand, i have to type "foobar" to get the null value?

I more wanted to know _where_ you want to "get the null value". What exactly do you need "the null value" for? Where does it have to appear? Why do you need it?

Yes, but WHERE?

HOW do you want to write those bytes? How do you write the others?

I want to write them in my script in maxscript, but that is the problem. I haven't found a functionality in maxscript that can do it.(If i understood from you correctly)

EDIT: The other bytes i created is by doing something like this

Code: [Select]

verHeader = "REVM" --4 Bytes
verChunkSize = bit.intAsChar 4 --4 Bytes
wmoVersion = bit.intAsChar 17 --4 Bytes
Format "%%%" verHeader verChunkSize wmoVersion to:out_file
Now i could have instead of written bit.intAsChar 4, i could have wriiten "x04" but the same result

Now i hope i answered your question but to answer "how to write them", i really hope there is a way in maxscript. If there isn't, isn't there a way to run an alternate program after the export and then input the null values? Though i would really dislike doing such thing in the first place. (Sorry for double posting)

You apparently don't use binary file IO. What you want is probably http://docs.autodesk.com/3DSMAX/16/ENU/ ... d30e172159 (http://docs.autodesk.com/3DSMAX/16/ENU/MAXScript-Help/index.html?url=files/GUID-423269A5-B395-4A90-8058-F96C0A24115F.htm,topicNumber=d30e172159" onclick="window.open(this.href);return false;)

The function in this case would be writelong
