I think the real challenge is that I'm working with an Actor not a UObject. If not your monsters array will be empty.

You could create a separate function Initialize () and call it after spawning the actor. Thanks for all of your advice ! RepNotify is triggered in two ways. It is one of the properties in the details panel.

(I know it doesnt sound optimal but it works in many cases). Your script should flow logically, I should be able to understand what you are doing just by reading the nodes, however there are multiple areas where the logic seems to break down. What Ive concluded investigating the code and playing with it: Replicated vars provided at spawn* will not show up in the Construction Script on Blueprints for that replicated actor. This is extremely difficult to solve I think. Character = GetWorld ()->SpawnActor (.) I was being stupid. Aside from the compiler error on line 13 from trying to assign a pointer to a value, it should spawn.

Cookie Notice When I use that method in my persistant level, it works perfectly fine. To learn more, see our tips on writing great answers. As I said before, it works when I put the spawners in the persistant level but when I delete them in the persistant level and create them in the Level2 (my sub-level) then it doesnt work (as long as I know, the get all actor of class is always empty). You create the spawners in the persistent level and everything is fine when you open the sub level? Alternatively, you can also use PostNetInit but that only works for clients and doesnt work for Actors that were originally part of the level. You could create a separate function Initialize() and call it after spawning the actor. So most likely it hasnt yet created the spawners in the sub-level by the time it reaches the point where it needs to get all actors of class. Could this cause any hiccups or other issues if the parameters also define which mesh to use? I thought to use a BeginPlay to pass parameters but it looks like this method is called by itself just when actor is spawned. There you can then pass all the parameters you need. Really basic question, where should this go? Unless one of the nodes is explicitly marked as a latent one (which I think comes up with a little clock icon on it) then you can assume the whole graph will execute before .

The open-source game engine youve been waiting for: Godot (Ep. UE44.22.1; Visual Studio Code; . I cannot confirm this. or is this an obsolete solution?

Therefore, I'm attempting to pass in a parameter at the Actor's creation that will change the staticMesh of the projectile based on what Key was pressed. c++ unreal-engine4 Share Improve this question Follow If youre in the editor you should be able to look in the world outliner to see if your actors are popping up too. How do you get out of a corner when plotting yourself into a corner. Same thing with your player character, The second screen shot is still bad, there were so many other things I had questions about I decided to just skip trying to figure out what is going on there, When you post screen shots of long lines of code, make sure you have the end of the first one in view when you take the second screen shot and so on that way people reading it can follow exactly where the code is going, it only takes one little pin to be off to cause a problem and if we cant see everything we may be chasing our tail for a while, Image 3, you are creating an array of monsters by getting all actors of class, does this array populate? I just tried to print the length of the array and it always shows 0. To learn more, see our tips on writing great answers. You can find more info about the method here, but essentially you would get a reference to the world, call SpawnActor using that UWorld reference while passing in four parameters: the actor you want to spawn, which is usually of type TSubclassOf where AActor can be any subclass of type AActor, the location of the actor to be spawned, which is of Just before getting all the spawners. BeginPlay will be called after FinishSpawning on both Client and Server so you can do initialisation of meshes etc. Also try to set the spawn info to Always spawn: And like phil_me_up answered, first parameter of SpawnActor should be AmySphere::StaticClass() FActorSpawnParameters &)': unable to convert the argument 1 from Been trying for 9 hours now, A new, community-hosted Unreal Engine Wiki. This has worked where I am calling a C++ class. I am unable to test it out myself right now but judging from the code this serialization step is executed after BeginPlay on clients. So you are missing the '()' at the end: Thanks for contributing an answer to Stack Overflow!

Not sure if its too late, but what you want is SpawnActorDeferred which sets up the object but doesn't complete the spawning process, where you can then set variables and what not, then call FinishSpawningActor to complete the spawning process https://docs.unrealengine.com/en-US/API/Runtime/Engine/Engine/UWorld/SpawnActorDeferred/index.html For example, you spawn a cube and set the color in the same frame on the server. It would be better to use BeginDeferredActorSpawnFromClass, that way the construction is ran after you initialize it. Applications of super-mathematics to non-super mathematics.

How did Dominion legally obtain text messages from Fox News hosts? Have a good day. Sometimes you would want to quickly place additional actors in the scene.
