To demonstrate, I have created two keybinds, an event, a function and a float variable. If you don’t know how to use input actions and input axes click here for a detailed run down on how to include these powerful events into your project. All of these attributes will be shared to our child actors. This actor can now be filled with events, input actions, variables, functions and more. To start, create a new blueprint actor and name it ParentActor. So I do not understand why Epic did not already make what my question asks for.3 Conclusion Parent Class Creating the Parent Class And I dont want to use map > Groups because I will make many Maps, thus I want BPs premade that contain Rooms + items spaced correctly - I can access from the Project. (Im from UE1 and grouping meshes together into BPs, and adding code - is much easier on design/updates, instead of placing individual parts in a Map - ill never do that again because it wastes so much time when I need to change groups of things. I would want BPs in BP for 1) the spacing to be exact for all units, 2) I need to place 20 HotelRooms in a map (which need code for Open doors), and 3) I need to edit the Chair BP later, and its collision boxes need to be separate from the HotelRoom volumes. Or if I want to make a HotelRoom BP and inside that is an Physics Chair BP. Well I disagree because even with the other guy’s usecase, he had a Dresser BP and things inside the drawer BP, that need to be separate. If you want to have a bunch of Actor As with ChildActorComponent Child Class B, C, D, and H … then you should make a blueprint based on Actor A for each one Ultimately, the reason why there’s not been a satisfactory answer that tells you how to do it, is because you’re not supposed to do it. (I’m not sure how to affect the spawn or Construct-change of Child Actor Component) - since Component variables have mismax.). So how can I add DT row variables in LootCrate BP (this part I know how) > to CastTO or BPI affect the that is spawned (dont know how)? And do I need that code in BeginPlay? for the Pickup03 armor - I have 6 DT row variables, which then read the DT for each armor piece. But do you have examples of each - how exactly to CastTo or BPI to the Child actor/component - so that I can access their variables from the Details panel in World view?Į.g. You can also use Interfaces to do a similar thing. Then you can cast to PickupBase and you’ll be able to access any functionality inside PickupBase from there. Make a class PickupBase and all of your PickupActors should be children of that class. If you have many different things to cast to, you can cast to the lowest common denominator in their chain. So it’s easier to have separate BP actors. So I need to get at the Pickup BP’s dropbox settings, to set which parts of the DT armor to spawn (because I can mix and match, or sometimes I want a Crate to spawn just boots, not all pieces - thus I need to be able to instance edit the variables).Īnd I need an actor inside an actor because I have some Pickups that spawn with physics shells, so they shoot out of the Lootcrate (as actors with a physics collision box that is separate from Crate BP), and when the box hits the ground, the physics box deletes, so the pickup doesnt move/push anymore. So for head, chest, legs, boots, etc - in that Pickup actor, I just use a dropbox variable - to select which DT row to read, and the Construct script then sets the Mesh, color, name of the matching Row handle.īut then I need to spawn that Armor Pickup BP in the LootCrate BP, or Armor Rack BP. It has complicated code to read a DT and each EACH armor piece in its Construct script. Ok so my Pickup03 is an armor set (6 individual parts, each can be set separately with 6 DT row handle variables). In general, if you think you need to do something in Constructor, you probably are approaching the thing from a way that will turn into a Foot Gun very quickly. If you want to have a bunch of Actor As with ChildActorComponent Child Class B, C, D, and H … then you should make a blueprint based on Actor A for each one, and set the Child Class and Template how you want them. Not always, sometimes there are some things you really have to do in Constructor, but they are usually pretty few and far between. (or approach this with a different tactic) If you need multiples, create more blueprints. Nope, that’s already handled by setting the Child Actor Class and Child Actor Template properties in the blueprint, and leave it alone. I wanted to add an Actor Variable to Lootcrate BP because I also need code in the Construct script to turn the into whatever that I set.
