Break statement not breaking, where to look for info?

Submitted by Endoperez on Tue, 2014-09-02 10:42

Hi all,

After a long break, I've once again found myself writing max scripts. I've more or less finished my script, except for this one weird thing.

I have two nested loops, for-i and for-j. I want to break out of for-j when a specific condition is met, iterate through the rest of for-i, and then have the loop continue at i+1 as normal.

Should be simple, right?

However, it seems the BREAK statement doesn't work! 

for j = value to bones_total_nr do
(
	if (another_value == 0) do
	(
		print("found a zero");
		break;
		print("it didn't break");
	)
)

This prints out:

"found a zero"
"it didn't break"

Break should break out of the for-j loop, but it doesn't. Am I misunderstanding something? Where could I find more information about this?

Thanks for your time

Solution

Thanks barigazy, I'm now using for-while!

I was using this resource:
http://www.scriptspot.com/bobo/mel2mxs/loops.htm

and relied on it too much without double-checking the information elsewhere. In this case, I mistakenly thought the Maya section also applied to the 3DS Max.

It seems like the MaxScript command for breaking out of loops is called exit;, not break; and while reading on for-while loops I also found out that the exit command is quite slow.

It's better to use for-loop this way

for j = value to bones_total_nr while (another_value != 0) do (print "Zero not found...jet :)")
