Definitely a basic topic...however, it requires quite a few statements to get around this. Am I missing something? I was doing a level 3 exercises yesterday where I needed two separate scores on the same page to equal 4 in order for the student to pass. I kept looking for an "and" function to follow an "If" statement, i.e., "IF variable 1 is equal to 2 AND variable 2 is equal to 2 THEN set SCORE_CORRECT=PASS" Seems simple enough, but I had to create several variables and mess around about 2 hours to get it to work using other methods.

Perhaps I missed something...I haven't programmed much in a long time and just upgraded to XE from 4.1.

BTW...OPUS ROCKS!

May seem really basic, but you can just nest another 'if' inside the first 'if' to check for 2 conditions.

Hi Mallette

if ((var1 == 2)&&(var2 == 2))
{
SCORE_CORRECT=PASS
}

or if you just need the total to be 4

if (var1+var2 == 4)
{
SCORE_CORRECT=PASS
}

If you are using the normal actions interface then FishBox is correct, simply nest the "if" statements.
If you are using scripting then Chris' suggestions are the way to go. Make sure you use the double ampersand (&&) - a single & is a bitwise AND, not a logical one, and will have a different effect. See this page for some more info

Hey, not one, but two ways...
Haven't fully evaluated either, but they appear logical. Operating at the high level, I've not yet quite figured out the order Opus evaluates things. I was a bit confused as to why I couldn't place a global If or whatever at the top level.

As to Opus script, I've not even figured out where it's located yet...

Now THAT's BASIC!

Thanks for your help.

There are two ways to work with scripts

script objects and script actions

This type would normally be a script action which
is added like any other action associated with a trigger.
(like left mouse click)

Actions dialog >> programming >> script
