So, I have been trying to implement custom anim nodes, but I have been running into a crapload of problems while trying to implement them with the outdated info found on the UE4 wikis and answerhub. I will probably hurl my PC through the room if I see another unresolved symbol error. 
Anyways, I have the following:
AnimGraphNode.h

{

{
BasePose.Initialize(Context);
}

{

}
I have also made sure to make a seperate editor module for my game, and placed the graph node header and implementation in folder associated with the module. As far as the module goes, this is how it’s been implemented.
GameEditor.Build.cs
// Copyright 1998-2015 Epic Games, Inc. All Rights Reserved.
using UnrealBuildTool;
public class PiratesAdventureEditor : ModuleRules
{
public PiratesAdventureEditor(TargetInfo Target)
{
//Make sure Pirates Adventure is added as a search path.
PublicDependencyModuleNames.AddRange(new string] {
"PiratesAdventure"});
CircularlyReferencedDependentModules.AddRange(new string] {
"PiratesAdventure",});
PrivateIncludePaths.Add("EditorModule/Private");
PublicDependencyModuleNames.AddRange(new string] {
"Core",
"CoreUObject",
"Engine",
"InputCore",
"UMG",
"Slate",
"SlateCore",
"RamaSaveSystem" ,

"AnimGraph",
"AnimGraphRuntime",
"GameplayTasks",
"PhysX",
"APEX" });
PrivateDependencyModuleNames.AddRange(new string] {
"UnrealED",
"AnimGraph",
"AnimGraphRuntime",
"BlueprintGraph"});
}
}
I know I have gone a bit overboard with the adds, but before I started to be showered with external symbol errors, this was a whole lot cleaner. Anyways, the error I am having right now is;

Anyways, I have no idea what I am doing wrong. I can kinda understand that the error lies with the AnimGraphNode, but I cannot for the life of me understand why it’s complaining. I have also tried changing GENERATED_UCLASS_BODY() to just GENERATED_BODY(), among a bunch of other things, but that only changes the errors visual studio throws at me.
