what does a , seperator do in an /if statement do?
ie

/if n (1==1,2==1) /echo hello

thanks

$target(x) should give the x coordinate of the target(This may be goofy and give the y). The x and y axis everquest uses is kind of goofy. If I remember correctly the x axis runs n/s and the y axis runs e/w (rotated 90 degrees from what you would expect basicly).

I have never seen a , used in an /if. (Just because I have not seen it does not meen it does not work)
, is used in $if though.

Thanks

Code: Select all

/if n $distance($calc($target(y)-$cos($target(heading))*10),$calc($target(x)-$sin($target(heading))*10))<3

found this in the getbehind system I was looking through a few min. ago and didn't know what the comma did.

Thanks for your reply about the x thing. I was in game and tested it while you were replying I guess. looks like n-s is Y, north is positive and south is negative. w-e is X, west is positive, east neg. and Z is up/down. up is positive, down is neg.[/code]

Kint, those aren't really parms for the if statement as much as they are parms for the $distance function.

From the MQ manual:

$distance(y,x)
Returns the distance to a location

Without all the fancy computations, it would just look like

Code: Select all

if n $distance(y,x)>3

Hope that helps.

how many && operators can you shove into one /if statement?

hehe, fairly certain there are no AND or OR operators in the macroquest /if statements.

Ran a test to confirm that...

Here's what you do if you have a situation that requires an AND:

Code: Select all

/if thing1==1 {
    /if thing2==2 {
        /dosomething
    }
}

Pretty simple -- but if you need an OR, it gets just a little bit more complicated:

Code: Select all

/varset l0 0
/if thing1==1 /varset l0 1
/if thing2==2 /varset l0 1

/if $l0==1 /dosomething

$l0 can be anything -- you can see how that works, though, right?

&& and || were implimented at one point, but I think they were always buggy... not going to dig into the source right now to find out.
