Do brackets help in logical operations?

IE: elseif Random > 75 && ( LilRandom == 4 || LilRandom2 == 4 )

That should be if Random is over 75, and LilRandom or LilRandom2 equals 4, but what I gather is that Oblivion will interpret it as:

if Random is over 75 and LilRandom is equal to 4, OR LilRandom equals 4.

Logically it should interpret it the prior, but with Oblivion, I'm not so sure. --MaXiMiUS 21:42, 9 April 2006 (EDT)


--JOG 15:21, 14 April 2006 (EDT)Doesn't help as far as I've tested it.

--JOG 04:51, 17 April 2006 (EDT) Didn't really read and thought you asked about AND/OR as bitwise operators. Of course brackets work but since OR always has priority over AND you need to include the AND part.

tabs and spaces

I just spent an hour searching for a bug in a script using &&:

Apparently certain combination of tabs and spaces between the two parameters cause the IF-Block to break processing of the script. No commands within the IF-Block or after the IF-Block are executed.


Here is an example:

http://home.tiscali.de/jo.ge1/tabs_working.txt

This one works fine: for each of the three objects you get a Journal entry when you activate it and can activate it as often as you like.


http://home.tiscali.de/jo.ge1/tabs_not_working.txt

The second one doesn't work: You just get the journal entry when you activate the first object, no activation, And the second and third object can't be activated at all.

Gotchas

The following if condition compiled (I forgot to type the last angleA):

if (angleA >= 0 && angleA <= 90) || (angleA >= 180 && < 270)

Once my script hit this line, it stopped working completely. No indication that anything was wrong. --Mrflippy 21:06, 15 April 2006 (EDT)


Also,

Sometimes a runtime error will occur where:

      if cond1 && cond2
         ;code
      endif

is not evaluated correctly in scripts. If you find a similar conditional statement is not functioning correctly, try:

      if cond1
         if cond2
            ;code
         endif
      endif

The reason for this anomaly is currently unknown.
