[Remastered] UE4SS: 1. How to call function with InputAction parameter and 2. How to detect combat start

[Ziqul]

Started digging in UE guts of remaster and got stuck. Would much
appreciate if someone will help figure this out, or at least point me in
the direction of where to look.


## Problem 1
For the love of me cannot figure out how to construct
`InputAction` for a function call.

For example:
Class `/Script/Altar.VEnhancedAltarPlayerController` has method
`ToggleWalk`. UE4SS tell that this method has one parameter called
`Value` (`StructProperty /Script/Altar.VEnhancedAltarPlayerController:ToggleWalk:Value`).

Going trough CXX Headers I can find out that this "Value" is of type
`FInputActionValue&` (`Altar.hpp:4615: void ToggleWalk(const FInputActionValue& Value);`).

Finding instance of `VEnhancedAltarPlayerController` (for example
`BP_AltarPlayerController_C`) and clicking "Find Function" in UE4SS
gives this hint: `StructProperty (InputActionValue) e.g.: (Prop1=Val1,Prop2=Val2,Prop3=Val3)`.

So in my code I am calling `ToggleWalk` like this:
`playerController:ToggleWalk({1.0, 0.0, 0.0})` and even thought there is no
errors - nothing happens. No matter if I "walk" or "run"!

I know that I am doing something wrong, but what?

### TLDR 1
How do I toggle walking state via UE4SS?


## Problem 2
I am trying to figure a way to hook into "combat start" (enemy becomes
aggressive, combat music plays, "IsInCombat" in CS), but only function
that I was able to find is `InCombatState` (`Function /Game/UI/Modern/HUD/Reticle/WBP_ModernHud_CrosshairSneakEye.WBP_ModernHud_CrosshairSneakEye_C:InCombatState`).
And that function works exactly as I need - it fires once when combat
starts, the problem with it is that it only fires when player is in
"sneak".

So the question is - are there any functions (or other ways) that can help
me determine when combat starts?

In relation to Problem 2 I am 90 percent sure that game should have some kind of function that is called when combat started. There should be some "StartMusic(BattleMusicFile)" function that "RegisterHook" should be able to accept.
I have watched all AkAudioEvent methods and there was nothing like that. I also watched all ReveiceBeginPlay (I think this one is more related to animations), also nothing there.
Does anybody know how music files are being started in Remaster?
