How to access a material instance variable from a blueprint object in Unreal Engine? created from SpawnActor()). No problem. Spawning refers to the process of creating an Actor, similar to New Object though having a physical presence in the game world means Actors are treated differently, because they have components like collision. Any logic in BeginPlay but before AActor::BeginPlay (usually Super::BeginPlay) is the only place where the client can do stuff to the Actor before replication. The problem is something else.

I'm currently trying to spawn a trap in my scene with the function "Spawn Actor" but, oddly, it don't want to take my static class as a UClass*. You can't pass parameters to a class constructor in UE4. So throw a delay in there for like 3 seconds and see if that solves the problem. I am unable to test it out myself right now but judging from the code this serialization step is executed after BeginPlay on clients. Have you tried printing the length of that array output of get all actors of class and see the length make sure you actually found the spawners? Replication and thus RepNotifies do indeed always seem to be triggered before BeginPlay. I have created the spawners by just placing them in the level. Do you have a screen shot? I have definitely had some trouble with this in the past. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? What's the difference between a power rail and a signal line? A potentially larger problem Im curious of is if RepNotify is guaranteed to send a variable with the spawn data in the same frame, but I havent dug that far under the hood in the ActorChannel. It is very appreciated ! For extra context, in the project there can be multiple characters spawned in the world. @phil_me_up could you give an insight on the idea behind StaticClass in EU4.

So I feel like there is something missing to tell the code that I want to look for spawners in the sublevel. No infos in the internet, I am searching for 3 days now. Alternatively, RepNotify setting on the var works as well. Is it unreal way of saying an instance of the class? I thought about the Ustruct bundle, but thats programming work for designers I want to avoid (although easy if needed, just boilerplate). Oh cool! Windows MacOS Linux References Syntax struct FActorSpawnParameters Remarks Struct of optional parameters passed to SpawnActor function (s).
