This has been the best tutorial on this functionality I have see so far. Especially the part from the 4:00 mark. ;)

[DonMatek]

Great explanation, this is one of the most frustrating things when you are a beginner, work on your script for half hour just to do some silly stuff and then your cast or reference isn't a valid one! :)

This helped me figure out a mod I was working on. Thanks so much!

[ConnorDoesRugby]

Thank you so much I had been stuck on my widget menu system for days and now it’s working

The blue pin in casting (Object (wildcard)) has been a headache but after looking this is like taking an aspiring. Very helpful and useful. I could only after get all actors from class and GET made a lot of stuff to work which was a problem earlier. Huge thanks sir!

5:04 a 3 days search for this answer came to an end !
Finally I could get the component velocity (a sphere falling) to a text widget :-)

I have an Actor Blueprint with a Mesh and a Widget Component. The Blueprint can be placed in the world by the player and the Widget will update over time(for example: a chest that has a bar which shows the player when the chest is full ). If the player can place multiple chests in the world, how can I reference all the chests individually so that the Widget Component can track them all?(When the player hovers/interacts with a chest, if I use the "Get All Actors From Class" node, how will it know what ID does that particular chest have?) Thank you for your videos and answers on the forums!

Thanks for the explanation. However, I have a case where I've made a parent of a sort of 'machine gun' type that uses specific type of bullets (different blueprint). Now, I want to be able to create a public variable that controls the speed of the 'bullets/projectiles' and I put as many children on the level as I need, but I want to access through the details panel of the 'machine gun' blueprint. You know, place the 'machine gun' on the level, and change the speed on the fly. So, I thought I'd do casting from 'machine gun' to bullets blueprint and get that variable, or get access to the min/max speed of the projectile. How do I do that cast? Or maybe I'm having a wrong approach?

I am trying to get a reference to another static mesh component located on the parent actor of the actor component I am referencing from.. When I use 'get components by class' to find static mesh components and then 'get' to get the right one - as soon as I connect the array to 'validated get' to set the variable it changes to a different mesh.. any idea why that might be happening?

My problem is that i have a gun which is spawned in the level on begin play. When i get reference to using all actors it will be empty until it is spwned and hence gives out error message. How can i get a referemce to the objects which are spawned ?

[nahiansharif]

oh boi, I was stuck for weeks trying to figure out how to reference my AI character with the widget, but 4:00 took all my pains

[NateEMG]

I want my enemy to be able to open door blueprints. Can I do it using this? If so, how?

[nitadebbarma]

Bro I heard that get all actors of class node is very expensive to use. Is it true.

[Neiv]

Do u know how do I get a reference for a widget thats its not created on a thirdPersonCharacter, i mean, my widget its created+addToViewport on a simple cube blueprint so I cant use the 'get player character' to conect to the cast node

[tpsher]

How i cant cast to not my charapter(my game haven't any pawn or player)

[mohammaddirani]

what if i have the same actor duplicated and i want to cast to it ???
