Hi, I can’t conceive what is wrong with the thing, my blueprint:

It’s supposed to make an array of spawn points at the BeginPlay, then spawn AI on every one of them when the room is entered. It does what it’s supposed to, but UE flags:

“Blueprint Runtime Error: “Accessed None trying to read (real) property CallFunc_Array_Get_Item in not an UClass”. Node: SpawnActor BP Enemy 1 Graph: EventGraph Function: Execute Ubergraph BP Big Room Blueprint: BP_BigRoom”.

Threads with similar error messages are not helping me in resolving this issue, any help would be appreciated.

You are appending scene component array with another scene components children components which seems to be some meshes.

Yeah, I do that in a couple more places and it all works fine, could you elaborate on what seems to be the issue here?

If the array is “scene component” variable type it can only append with another “scene component” variable type. Mesh (Sphere in your case) is not a “scene component” variable type, it is a “mesh component” variable type.

I changed all meshes to scene components, made the array with corresponding types, it still works, but the error messages are also still there.

Print string all the enemyspawnpointlist (in the loop you already have).
