00:00:13:11 - 00:00:14:15
In this tutorial, we'll
00:00:14:15 - 00:00:17:17
look at Invent ability
to create variable logic.
00:00:18:11 - 00:00:21:06
So this allows you to create and perform
more complex
00:00:21:06 - 00:00:24:07
and intelligent behavior
within your MegaEdit product.
00:00:24:29 - 00:00:29:07
Variable logic is essentially a collection
of rules, with each rule
00:00:29:07 - 00:00:31:26
being made up of a series of conditions
and actions.
00:00:33:09 - 00:00:36:02
This video will run you
through the high level process
00:00:36:02 - 00:00:40:00
of creating some simple logic, conditions
and actions to demonstrate
00:00:40:01 - 00:00:41:22
how this can be used in real life.
00:00:41:22 - 00:00:44:07
Examples.
00:00:45:27 - 00:00:47:02
Now, before we begin this.
00:00:47:02 - 00:00:48:01
Process, we do need.
00:00:48:01 - 00:00:51:15
To spend a bit of time
understanding the initial product setup.
00:00:51:15 - 00:00:53:02
I have here.
00:00:53:06 - 00:00:58:19
So our initial Invent template is a very
simple setup consisting of functionality
00:00:58:19 - 00:01:01:26
that we've covered in previous tutorials
in this series.
00:01:02:25 - 00:01:05:25
So this consists of a few resource groups
00:01:05:25 - 00:01:08:24
which we're going to be utilizing
primarily these bottom three.
00:01:09:15 - 00:01:10:18
So we have a clip.
00:01:10:18 - 00:01:13:04
Art group
which controls this. Graphic down in.
00:01:13:04 - 00:01:17:27
The bottom left of our business card,
we have a logo set,
00:01:17:27 - 00:01:19:01
which is just two different.
00:01:19:01 - 00:01:21:08
Variations of this logo shown. Here.
00:01:22:14 - 00:01:24:22
And we have background color sets.
00:01:24:22 - 00:01:27:17
So these are color pickers
to colors, to be precise,
00:01:28:06 - 00:01:32:21
which will control the background of this
frame here.
00:01:32:21 - 00:01:36:03
So the same frame
that's utilizing this clip art.
00:01:36:03 - 00:01:37:04
It will.
00:01:37:04 - 00:01:39:27
Control.
The background color of that frame.
00:01:40:04 - 00:01:42:00
And that's essentially acting
as a background.
00:01:42:00 - 00:01:43:07
Color for this particular.
00:01:43:07 - 00:01:45:13
Document.
00:01:50:25 - 00:01:51:09
Built
00:01:51:09 - 00:01:55:00
from those resources,
we have three variables available.
00:01:55:18 - 00:01:58:13
One of them is a logo set variable.
00:01:58:14 - 00:02:01:22
So that's which of the logos we're using.
00:02:02:24 - 00:02:04:06
We have a graphic set.
00:02:04:06 - 00:02:05:19
That's the.
00:02:05:21 - 00:02:07:13
Graphic that we're using.
00:02:07:13 - 00:02:10:11
And the background color set,
which is controlling the background
00:02:10:11 - 00:02:13:05
color of this frame.
00:02:13:13 - 00:02:15:13
Now do note that each of these variables.
00:02:15:13 - 00:02:17:29
Is set to a dropdown.
00:02:17:29 - 00:02:19:13
As it stands at the moment.
00:02:19:13 - 00:02:23:16
At the time of recording this video,
setting up logic on
00:02:23:16 - 00:02:26:12
your forms is best done with.
00:02:27:04 - 00:02:28:18
Dropdown. Entries.
00:02:29:28 - 00:02:31:18
This may change as time progresses.
00:02:31:18 - 00:02:33:09
However, at the moment, please
make sure you're
00:02:33:09 - 00:02:37:19
utilizing dropdown variable types
if you want to.
00:02:37:19 - 00:02:41:09
Utilize form logic.
00:02:42:15 - 00:02:44:26
Now to actually define
some logic on our form.
00:02:44:27 - 00:02:50:23
If we go to the variables
tab and click on set up logic,
00:02:50:23 - 00:02:52:21
that will give you a separate window
which looks.
00:02:52:21 - 00:02:55:25
Something like this.
00:02:57:21 - 00:02:58:26
We start off by clicking
00:02:58:26 - 00:03:01:08
the add logic button on the top right
hand side
00:03:02:00 - 00:03:06:17
that will and add a new entry of which
we can have a maximum of 50 of these,
00:03:07:02 - 00:03:09:21
where we can specify a name,
a description.
00:03:10:01 - 00:03:11:23
And then set up our actual.
00:03:11:23 - 00:03:15:07
Rules for that logic statement.
00:03:21:06 - 00:03:24:17
So first we'll specify a name
and what we're essentially trying
00:03:24:17 - 00:03:30:06
to get this logic statement to do is
to automatically change the logo that's.
00:03:30:06 - 00:03:31:11
Being utilized.
00:03:31:11 - 00:03:33:15
Based on the. Background color selection.
00:03:34:28 - 00:03:35:16
So we can give it an.
00:03:35:16 - 00:03:38:04
Appropriate name.
00:03:40:20 - 00:03:44:00
Optionally, we can give it a description
00:03:53:01 - 00:03:53:26
and then we can start.
00:03:53:26 - 00:03:56:11
Building our rules.
00:03:56:14 - 00:03:59:10
So each rule requires first a condition
00:03:59:23 - 00:04:04:16
and there's a maximum of ten
assigned to a single rule.
00:04:05:22 - 00:04:08:21
So I can click add condition
down on the right hand side
00:04:09:07 - 00:04:11:25
and then you just building up
the required statement.
00:04:12:17 - 00:04:15:27
So it's an IF statement that we're building
and the options we have.
00:04:15:27 - 00:04:17:21
Available are.
00:04:17:21 - 00:04:20:00
Always or never.
00:04:20:00 - 00:04:23:14
And then optionally,
we have a list of all different variables
00:04:23:14 - 00:04:27:16
that we have specified.
00:04:27:16 - 00:04:29:22
So we're basing this
around the background color.
00:04:30:02 - 00:04:33:20
So if I say if one of our variables
called background color
00:04:34:12 - 00:04:39:03
and then we have equals or not equals,
00:04:39:03 - 00:04:42:16
then we have a specification of the values
available.
00:04:42:25 - 00:04:46:01
For that particular variable,
which in this case are.
00:04:46:01 - 00:04:47:19
Navy or white.
00:04:48:22 - 00:04:49:24
So I could say that if the
00:04:49:24 - 00:04:52:00
background color equals navy
00:04:54:28 - 00:04:56:28
and then we want an associated action.
00:04:58:27 - 00:04:59:19
So I can say add.
00:04:59:19 - 00:05:03:09
Action,
and then we want to dictate what happens
00:05:03:17 - 00:05:06:28
if that condition is met.
00:05:07:24 - 00:05:12:16
So we want to change the logo set
and we want to set the value of.
00:05:12:17 - 00:05:15:19
That variable. To be.
00:05:15:23 - 00:05:18:00
The white version in this case.
00:05:18:00 - 00:05:20:21
So what that means
is that if the Navy background color
00:05:20:21 - 00:05:23:26
is selected, the logo.
00:05:23:26 - 00:05:27:28
Will change to the white version
of the logo.
00:05:33:29 - 00:05:36:08
Notice
that we can have multiple conditions
00:05:36:08 - 00:05:39:28
or multiple actions per rule.
00:05:40:15 - 00:05:43:02
We also need to define an else.
00:05:43:04 - 00:05:45:06
Statement for this rule as well.
00:05:45:06 - 00:05:47:14
So what happens
if this condition isn't met?
00:05:48:17 - 00:05:51:14
So I can say add else
00:05:52:00 - 00:05:54:06
that will give us a second set of actions.
00:05:54:13 - 00:05:59:13
So these are the actions that will happen
if this condition or multiple conditions
00:05:59:13 - 00:06:03:01
that we've defined are not met.
00:06:03:15 - 00:06:05:16
So else add action
00:06:07:12 - 00:06:08:06
logo set.
00:06:08:06 - 00:06:09:14
Variable
00:06:10:26 - 00:06:12:17
set value
00:06:12:17 - 00:06:17:00
to the other variable
or the other entry we've got.
00:06:17:00 - 00:06:23:22
Within that variable.
00:06:23:22 - 00:06:25:23
And that's our statement completed.
00:06:25:23 - 00:06:29:09
Just to show you this before we move
on, you'll notice that when I'm
00:06:29:09 - 00:06:33:09
setting my actions, we have a list of both
the available variables
00:06:33:22 - 00:06:37:11
and the fields
that we have set to dynamic.
00:06:38:16 - 00:06:40:29
So notice
if I select one of the fields, my
00:06:41:07 - 00:06:44:18
a available actions
become a little bit different.
00:06:45:06 - 00:06:48:01
So we have the ability to show and hide
a certain field.
00:06:48:22 - 00:06:51:19
We have the ability to directly change
the background color,
00:06:51:19 - 00:06:54:05
which we could have utilized
in this particular rule as well.
00:06:54:26 - 00:06:57:02
Change the size at the position or.
00:06:57:02 - 00:06:59:15
Change the image that's being utilized.
00:06:59:15 - 00:07:01:14
So the way in which you approach this.
00:07:01:14 - 00:07:03:04
Is completely up to you.
00:07:04:17 - 00:07:06:03
In this case, we're going to
00:07:06:03 - 00:07:08:03
stick with changing one of our variables.
00:07:09:10 - 00:07:10:29
As that's nice and easy based on our.
00:07:10:29 - 00:07:13:05
Setup.
00:07:16:10 - 00:07:18:13
With that defined, I can click on Save
00:07:19:13 - 00:07:23:18
and then going to go ahead and export
the MEX file and.
00:07:23:18 - 00:07:25:28
Re-Import that into our MegaEdit.
00:07:25:28 - 00:07:27:03
Product.
00:07:27:08 - 00:07:31:03
So with our product loaded in MegaEdits,
we can actually test the behavior.
00:07:31:03 - 00:07:32:23
That we've just set. Up.
00:07:32:23 - 00:07:35:07
So if we recall, we'd specified it
00:07:35:07 - 00:07:38:21
so that when we change the background
color, the logo selection changes.
00:07:39:24 - 00:07:43:19
So if I change the background color,
you can see that the chosen logo.
00:07:43:26 - 00:07:46:06
Has. Switched.
00:07:49:09 - 00:07:51:09
Now, in this case, we still have that.
00:07:51:09 - 00:07:52:19
Logo set variable.
00:07:52:19 - 00:07:56:22
Being displayed on our form
as it's been automatically changed.
00:07:57:07 - 00:07:59:18
Hypothetically, we could get rid. Of that.
00:08:00:10 - 00:08:03:27
Variable on the actual form,
so the variable will still be
00:08:04:02 - 00:08:05:11
present in the background
00:08:05:11 - 00:08:07:25
and it will still be being driven
by the background color.
00:08:08:08 - 00:08:10:14
But we don't have to
make it present on the form.
00:08:11:26 - 00:08:13:15
Just to remind you where to do that.
00:08:13:15 - 00:08:17:06
Same as with a previous video.
00:08:17:06 - 00:08:23:18
If we go to variables and set up forms,
we could get rid of that.
00:08:23:18 - 00:08:25:09
Logo set variable on.
00:08:25:09 - 00:08:27:28
The form itself.
00:08:31:27 - 00:08:33:23
So that's a very simple overview
00:08:33:23 - 00:08:36:24
of setting up rules
and setting up logic on your form.
00:08:37:07 - 00:08:41:01
Of course, you can accomplish
much more complicated actions than that.
00:08:42:14 - 00:08:43:25
Hopefully that gives you an overview.
00:08:43:25 - 00:08:46:12
We'll try to cover
some more detailed functionality.
00:08:46:20 - 00:08:50:12
In future videos on this topic.
