The Null Value

[abdalrahman9]

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.

isn't it something like

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?

[abdalrahman9]

i want to recreate something like this:

[schlumpf]

Yes, but WHERE?

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

[abdalrahman9]

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

[abdalrahman9]

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

The function in this case would be writelong

Thank you it worked! The help is much appreciated. Now i can finally continue on my work.
