UITacticalHUD and the Target System

[btysgtmajor]

I'm still fairly new to XCOM 2 modding, but, I was wondering if anyone knows if there are any events triggered or any way whatsoever to know when UITacticalHUD ends up calling RaiseTargetSystem() or LowerTargetSystem()? I've tried polling the class, but, so far I've only been able to do it via the Visualization Observer Interface (or whatever) but those events don't trigger when the targeting system goes up or down.

 

This is the last sticking point for a mod of mine. Otherwise, I have to override UITacticalHUD and it creates all kinds of conflicts with other mods.

 

Any thoughts/advice? Or am I missing something obvious?

 

Thanks in advance!

FYI, Robojumper has suggested a mod called "NobodySawThat" might have a way to accomplish what I'm looking to do. I'm going to check that out when I get the chance, and hopefully report my findings here.

As promised, I'm sharing my results.

 

Thanks to the mod referenced above, I found a snazzy way to be alerted to essentially ANY variable change! Take a look at the line below and I think you'll see how you can use it most anywhere:

WorldInfo.MyWatchVariableMgr.RegisterWatchVariable( HUDScreen, 'm_isMenuRaised', self, ToggleTargetSystem);

In the case above, we're registering the variable/property "m_isMenuRaised" against the "HUDScreen" class (in this case a UITacticalHUD), and telling it to notify "self" and, when doing so, call the "ToggleTargetSystem" method.

 

Hope this helps someone else!

That being said, RegisterWatchVariable should be considered a last resort for ONLY UI ELEMENTS. Often, these class variables contain data relevant to the internal state of the object. If there is anything that changes the GameState, you should not rely on it, and use the built-in `XEVENTMGR if possible.

An excellent point.

 

@robojumper: Have you considered putting a guide/document together with all these great tidbits? I've found them most helpful so far.
