How can I create this condition using a single event in Construct 3?

Coming from using other game engines, I am learning how to use Construct 3 and I find it interesting, but in its event system I find something that really bothers me all the time because I can not develop my logic with enough versatility. With other game engines, I am used to creating these kinds of conditions using a single event:

Event 1: If (a=1 and b=2) or (c=1 and d=2) then (actions)

This is something that even the extremely simple and basic game engine called Scratch allows to do easily. However, surprisingly, it seems that with Construct 3 it is not possible to use a single event to create such a condition, but rather I have to use at least 2 events, in this way:

Event 1: If (a=1 and b=2) then (actions)

Event 2: If (c=1 and d=2) then (same actions)

Since I have no idea about javascript, I want to ask: is this an unnecessary restriction of Construct 3, or is it an unavoidable limitation of the javascript language itself?

Note: I am not looking for workarounds to handle this issue, I am just looking for an answer to my question.

You probably want to use Ternary operator to put action based on several criteria under single event like what I do in following case: onicstudios.wordpress.com/2021/02/04/formula-that-moves-object-efficiently

Try search on forum with keyword 'ternary' so you will end up with relevant topics.

The most extreme use case I came up with is this one:

alextro Thanks, but that can not be used in many cases. For example, how could this be done using a single event and without having to write javascript code?:

Event 1: If (Sprite1 is visible and Sprite1 is mirrored) or (Sprite2 is visible and Sprite2 is mirrored), then (actions)

Here, again, Construct 3 forces me to use two events and repeat the same actions, or use a function for something that I think should be able to be done in a simpler way.

I really don't understand the reason for these restrictions in the Construct 3 event system.

I was hoping to be able to do at least something similar to this:

I think this would allow us to create the logic in a much more versatile, easy and fast way.

In expression you directly assign value to specific attribute. The comparison can be anything but it needs to be put into a value/property/attribute. works just like if else condition (ternary) even nested one. So yes everything were put in action and you can leave the condition blank or under certain condition.

I honestly think that the AND/OR operators should be better implemented in Construct so that it would be possible to easily perform all kinds of combinations between them using the visual event system. Also, I think this is something fundamental, since these kinds of operators are something we are using all the time while creating game logic. I am just learning how to use Construct. The first time I wanted to use the OR operator in a single condition within an event and I saw that suddenly all the conditions in the event became OR, I thought "Huh? What is this? what's going on here?", and it is something that I am finding quite restrictive and rigid. In fact, I find it downright strange that a game engine as complete and powerful as Construct offers so little versatility when it comes to using something as fundamental as the AND/OR operators in its event system, to the point that at first I even thought that maybe I didn't know how to find the option to be able to make combinations with them, or maybe it was a limitation of JavaScript language itself. But if JavaScript doesn't have that limitation, I don't know why Construct has it in its event system.

Hopefully this will improve because I really like Construct in many other aspects.

Kind regards.
