Can someone help me with @random() or RANDOM:

I want to have my program go to 1 of the following labels at random:

:example-label-number1
<do something>
:example-label-number2
<do something>
:example-label-number3
<do something>

Seems it should be very easy for a VDSpro, hehe
Thanks in advance...

Hi vtol777,

Welcome to the forums and let me see if I can give you and example
here of what you need:

[FreezingFire]

Just make sure that you have all the necessary labels, otherwise if a
number is generated that doesn't correspond to a label, you'll get an error.

I guess the random stuff has to be complex to work, I was hoping it would be simple without things in the Evloop - etc.., will that interfere or slow anything else down in my program(I'm gonna have to learn what its doing, hehe)?

[FreezingFire]

Actually you can use the standard "evloop", Garrett posted a variation of
the standard one:

[vtol]

I studied the Event stuff with what I had to study with, hopefully I'll tie it all together soon, thanks, the basic Evloop is what I'm used to...

[Garrett]

Sorry about that. We all kind of develop our own preferred habits (not
saying if they are good habits or bad!). I'm in the habit of checking the
%E from the event for when I need to capture an event, parse it and
then allow me to pick the final destination of the event. Unfortunately,
now I use that code even when it's not really needed, such as the
example above.

The random is not that complex, but if you are still a bit new to VDS, then
it may seem a bit complex at first until you've played with it a few times
and get the hang of it. It'll come to you quick enough.

Just take your time, run your code through the stepping in the IDE, watch
where the code goes etc.. Look at the code, verify the commands and
functions with the help file so you can try to understand what is going on
with things.

And of course, if all else fails... Just ask here at the forums. Trust
me, we don't bite... (Well, maybe once in a while.)

[FreezingFire]

You'll eventually get it.

What Garrett's version does is put the event in a variable, and if there's
an event loaded in the variable it goes to the event, otherwise it loops
back.

With the basic event loop, it waits for an event, then when one comes along
it goes directly to the event.

Garrett's version is useful when you need more control over events, although
it will work for simple event handling too.

Would Garretts method help in situations where the Evloop goes back to labels (kinda double checking) when you dont really want it too? Maybe you helped me find a fix to another one of my problems, lol, triple dialog menu, where the program needs a Radio checked and to LIST box items selected before continuing, thanks...

[Garrett]

Yes, exactly like FreezingFire said.

One example of this, is that I have a program that is an icon in the
system tray. This tray icon is a menu to launch programs. The
programs it gets are from two sources, the desktop shortcuts and
it's own folders and shortcuts.

Basically, what has to happen here, is that I have to dynamically generate
menu's. Now for me, I have well about 200 shortcuts in this little menu
system. Each having a MENU event. Mind you, I'm not in the mood to
try and generate 200 MENU branches, so instead, I use that EVENTLOOP
you see above, but I add a little code to it and find out what event has
just happened. IF it's one of the MENU events, then I send the event
to a special branch where I parse out the name of that menu event.

I'm not sure you understand what I mean on that. I'm not always very
good at trying to explain things.

Here's the EVENTLOOP of the program I am talking about:

[vtol]

No not at all, Events was just one of the things I needed help with as Random.
I search string POS (positons) text, files and so on in some of my homemade utilitys at my website. So from what you've said is what I have been missing and needing, full control of event traffic, thanks again Garrett and also FreezingFire, appreciate it highly.
cheers

[Garrett]

Well, if you need more help on that, and not so complex sounding, just
come back and let us know exactly what you are trying to do, and we'll
try to give you something as simple as possible.

[vtol]

Well, I was hoping I was doing something wrong, but after I edited your script a bit, it still just goes to the same label everytime.(I left out the Event section since I didnt need it where I needed the random lines)

%%RandomBranch = @RANDOM(1,3)
IF @equal(%%RandomBranch,1)
GOTO label2
ELSIF @equal(%%RandomBranch,2)
GOTO label3
ELSE
GOTO label3
END
goto skiplabels

:label1
:label2
:label3
:skiplabels

------------------------------------------------------

Heres what I had before(never worked either):
%%random_terrain_number = @RANDOM(3)

IF @equal(%%random_terrain_number,0)
goto label1
end
IF @equal(%%random_terrain_number,1)
goto label2
end
IF @equal(%%random_terrain_number,2)
goto label3
end
IF @equal(%%random_terrain_number,3)
goto label4
end

:label1
:label2
:label3
:label4

*I left out some technical things above in the labels to make the overall picture look easier.

[vtol]

oops

the second 'GOTO label3 ' should be 'GOTO label2 '

I goofed re-editing it on here, lol sorry
