"or" conditional with part-type

Dustin Rambo:

That makes perfect sense, I will tinker with it and see what I come up with. Thank you very, very much!

Good news is that the session tag is returning the correct values

Bad news is that something isn't working as expected. maybe it's the conditional, maybe not.

Let me ask a silly question;

The way i've got the code structured, would the "Doing Stuff" portion execute for either part-type, or does the first part-type map to "doing stuff" and the second to "doing nothing"?

I was thinking it was something like

if(part type == this OR part type == that) {do stuff}

else { do nothing}

But it seems i'm getting 

if (part type == this) {

     do stuff

}else {

     if(part type == that) {

          do nothing

     }

}

Pardon my loose pseudo code

I appreciate your help, either way!

Brian Mucha:

I think it should work for either. Lets walk through this.

 

[[?

     [[?x[[S48:0art-type]]x::xParty Hostx::T::F]]

     [[?x[[S48:0art-type]]x::xOmega Psi Phix::T::F]]

::T::

     DOING STUFF

::

     DOING NOTHING

]]

 

Say the Part Type is 'Party Host'. So that S48 tag evaluates to this:

 

[[?

     [[?xParty Hostx::xParty Hostx::T::F]]

     [[?xParty Hostx::xOmega Psi Phix::T::F]]

::T::

     DOING STUFF

::

     DOING NOTHING

]]

 

So, the first conditional is true and the second is false. (If xParty Hostx contains xParty Hostx then T else F)

 

They would evaluate to this:

 

[[?

     T

     F

::T::

     DOING STUFF

::

     DOING NOTHING

]]

 

That means... If TF contains T then Do Stuff else Do Nothing.

 

If the PartType was Omega Psi Phi it would be If FT contains T then Do Stuff else Do Nothing.

 

Since both TF and FT contain T, the DOING STUFF block should be returned in both cases.

 

And if Part Type was neither, then it would be If FF contains T then Do Stuff else Do Nothing. (And presumably your DOING NOTHING block is actually empty.)

Oooh, ok, I see. You really helped me to see what I was missing. I was brought up in Java and this is quite different from the if else statements that I am used to.

I'll be able to make good use of this, thanks a million!
