Hello i want to know how to set (State) variable of the (AC_Base) inside the (AC_Base_Child) child. i want to change the variable inside the parent not the child ):
Hey @LuBuSniper!
Something to understand here is the parent/child relationship is of CLASSes(violet) not objects(blue).
This is on the player blueprint. Notice it is saying “AC Base Child” as you have named it, as the target, with target being an AC Base Child OBJECT.
Do you possibly have an “AC_Base” AND an “AC_Base_Child” on the player?
Do you need both if Child is doing everything the Parent is doing? (meaning parent logic is running 2x, once with the child’s logic and once without)
Here you are saying “Use “Do It” event on AC Base Child”. You could also pull in AC_Base and pull off it to have it do the same if you wish.
Hope that helps!
you are right, 2 ways to do this, first i have to find a way to get AC_Base and activate the custom event inside the child or i have to get component by class of the parent, i will think about it. thank you so much
i have tried this way, it worked inside UE4, but it didn’t work in UE5! UE5 is full of bugs i guess 
If you spawned the component or child actor correctly - and assigned the Parent - then the parent variable is avaliable to you for callback.
Then in the component you can do this->parent>cast to because you are trying to access a specific instance to change its values, and from it update the value you need.
Essentially any Character/Animarion interaction should work in a similar fashion.
And yes, its totally possible this too is broken in ue5.
maybe i have to look for another game engine. the retargeting tools is also broken. i don’t think if they listen to the Users at all.
Well, I can settle you on that.
They never have, and never will.
When you suggest something - and they end up doing it which is possibly 1 in a 1 trillion of a chance, even if you can prove it was your suggestion that started the process, or even if you give them code via a properly formatted Git Pull Request: They will f*ck it up into a dystopian version of what you suggested and make it not work anyway.
So… don’t hold your breath on Epic doing anything except for what they are known to do:
Erode your rights with horrible TOS.
Fly in the face of FTC rulings and pay fines.
Steal ideas from other developers and get sued into having to settle - or worse, make money on other people’s back without providing any recompense at all (even on Patents!)
Sue little kids for “cheating” - because you know, how dare they?! their families now need to pay a few billion for having kids smart enough to figure out just how stupid epic is and pointing it out.
Make changes to the engine literally no one welcomes, or even asked for.
Oh. And apparently, of late, also enforce some sort of BS where you can’t write the word slave in your code as a term? Though, I think this is just some BS streamers picked up with little to no truth. EPIC doesn’t have access to your code unless you grant them access, and you don’t need to talk to them to publish so long as you stick to the agreement. However the fact any official document at all anywhere makes any statement at all about whatever the f you should or should not do with your private code base… well, that’s just one more example of the blatant overreach they attemp - Until you/someone sues them into oblivion for even trying. Which you can, and they’ll end up settling on because they can’t possibly win…
OH OK… I looked it up, it’s even worse!
Basically the reason the engine doesn’t work is that they went full rtard on all fronts! Including Coding Standards for their emploees!
On the wake of GamerGate 2.0 this is quite Astounding! 
I’m surprised people aren’t already up in arms and boycotting any game made with Unreal
Honestly, change engine. At this point its not even worth the “free” stuff they give you.
Cry works better.
I’m speechless
