Conditional logic is a MUST if you want to create more complex prototypes. The existing setup works well for 'Dribbble designs' and very simple apps, but with the use-cases that we're dealing with in our company, it's impossible to create a functioning prototype without variables and conditional logic. We currently use 'Just in Mind', but as Adobe users and followers we would obviously love to switch to an Adobe tool that can do just as much. Fingers crossed something will be included in the next update!

Let's try and create a journey trigger, where the user can create different journeys in the prototype section, and trigger them on action e.g. when user reaches this page or when user does this action start this page, or when this journey ends revert to this page. I believe this could open a great door for people who do testing on big projects such as my self where i need to create a big project and test different aspects without having to switch file all the time.

Really really waiting for variables management, to make the user flow easier, with fewer artboards, and expand the possibilities of interaction, with multiple navigations.

In my view, this is the single most valuable feature in any prototyping tool. Without this, I consider XD as just an eye candy tool like so many on the market today.

I would like to be able to apply conditional to an animation.
Example: When you click on certain button, depending on the screen, the action should take a particular screen

This would be great and hopefully the step needed to stop me having to use Axure for prototypes requiring logic.

For XD to be useful for any game designer, it must have logic, conditional statements in any form so that a prototype can show some form of gameplay.

I object to my idea (logical operators for voice triggers that are in the trigger syntax) being merged with this post.

- My idea is low-hanging fruit that could be implemented very quickly.
- The post my idea has been merged with is on a GENERAL solution to logic, which may be months or years away from being implemented

It would be great to have logical operators (AND/OR/NOT etc.) for voice triggers.
 
Usecase:
- Suppose your prototype asks your user to choose from 3 options (e.g. flavors)
- Suppose only 3 options are available (Strawberry, Chocolate and Vanilla)
- Suppose the user responds (voice) with something else than these 3 options
- Suppose you want your prototype to respond "We don't have that, please choose between Strawberry, Chocolate or Vanilla"
 
The amount of "wrong" responses is infinite, so you cannot make a trigger for the whole dictionary. But what if:
 
You can combine voice triggers in an OR function:
trigger : voice
command : strawberry OR chocolate OR vanilla
voice response : coming up!
 
And cover all other scenarios in a NOT function:
trigger : voice
command : NOT strawberry NOT chocolate NOT banana
voice response : I did't get that, please choose between strawberry, chocolate and vanilla
 
Possibilities would be almost endless!!
BTW the prototype I attached ONLY responds to the 3 flavors. Saying something else does not trigger a response...

I will think about it if possible i can make a plugin for that

Yes I agree we very much need conditional logic!
Once you get to a certain level of sophistication with your model it becomes frustrating for the customer that you can't take it to the next level of reality. Sometimes the customer mistakes this constraint for lack of effort or diligence, which make me look at other tools.

Live menu for an item where options related to item can be selected/deselected to configure aforementioned item.

Eg.

Let's say I want to configure a pizza. Let's say I have crust, topping and size and variables.

If I select option #2 from crust, option #4 from the toppings, and the extra large size, I want to the pizza-configuration menu to remember my options before the last one (in this case size).

If I have to create a state for every pizza configuration and I would have to create a massive amount of states. Might as well program it then.

Thanks for your attention.

This is a must for me to starting using Adobe XD and streamline my workflow to stop using Sketch/Axure. Thanks!

Support conditions in prototyping?

For example, if {{userName}} has {{1 or more items in basket}} then show populated checkout page, else show empty checkout page.

With all the tools out there, this is why I have always stayed with Axure... I was so delighted when when Adobe came up with XD so you can imagine how let down I was when it did not have any conditional logic.

Agreed! For now, I've created a "demo scenario picker" in my prototypes (a type of overlay). Once you hit a fork in the road, you pop up the overlay and then choose your own adventure. Kind of breaks the flow, but I can keep everything in one file. Not awesome, but it's still better than creating multiple versions of prototypes and separate files.

Absolutely true! Especially in Lean UX when you want to rapidly iterate and test.

Being able to assign a few global variables would be a game-changer IMO.

An intuitive way is to add simple "if var = x" conditions to the "pick-whip" style hook-ups between each artboard. You could even color code them for easy identification.

In our workflow, we have an app that has several release phases. Having a "if version=1.2 show/go here" and a "if version=1.3 show/go elsewhere" connection to a button, would help us to keep working in a single XD file, instead of having duplicate files per milestone/build.

It would also be valuable to implement proper layers or layer comps where those variables could determine visibility. This might be easier and more intuitive to manage and implement than doing variables on an object by object basis (although that should come at some point also).

This would be very helpful to simulate a user journey. Something even as simple as changing the state of an artboard after an interaction would help.

For instance, a "My orders" view for an shopping app has an empty cart until a user adds something to their cart. Instead of two separate artboards, there is just one "My orders" that changes its state. This would reduce the possibility of the user ending up back at the first one via some other path because the other interactions on the "My orders" artboard are hooked up to other things.

On a mobile device or tablet some interactions are based on specific user input... be it a form field with specific data entry, touch based gesture, or selecting specific items on a single screen in order... this request would be the ability to add those conditional interactions into our prototypes.
