Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

how to extend SAnimationGraphNode (link Errors)

Does anyone know how to extend SAnimationGraphNode ? im trying to create a widget control on my custom node. Custom animation sequence node and graph node works perfectly, the issue is with SAnimationGraphNode when i try to contruct the actual widget.

 /* CPP File */
 //     Adapted from SGraphNodeSequencePlayer
 #include "Animation/SGraphNode_CustomNode.h"
 //    Engine
 #include "Widgets/Input/SSlider.h"
 #include "Animation/AnimBlueprintGeneratedClass.h"
 #include "Kismet2/KismetDebugUtilities.h"
 #include "Kismet2/BlueprintEditorUtils.h"
 //    Custom Graph Node extended from UAnimGraphNode_AssetPlayerBase
 #include "Animation/AnimGraphNode_CustomNode.h" 
 //     Custom Anim Node extended from FAnimNode_AssetPlayerBase
 #include "Animation/AnimCustomNode.h"
 void SGraphNode_CustomNode::Construct(const FArguments& InArgs, UAnimGraphNode_Base* InNode)
     this->GraphNode = InNode;
         // Commenting this line it does compile (but, with no widget on node)
     SAnimationGraphNode::Construct(SAnimationGraphNode::FArguments(), InNode);

 // Header File
 #pragma once
 #include "CoreMinimal.h"
 #include "Layout/Visibility.h"
 #include "Widgets/DeclarativeSyntaxSupport.h"
 #include "SNodePanel.h"
 //   original include line of SAnimationGraphNode from SGraphNodeSequencePlayer.h does not work ("can not open source file..." intellisense error)
 //#include "AnimationNodes/SAnimationGraphNode.h"
 //    needs to be the full line direction
 #include "Editor/AnimationBlueprintEditor/Private/AnimationNodes/SAnimationGraphNode.h"
 class SVerticalBox;
 class UAnimGraphNode_Base;
 struct FAnimCustomNode;
 struct FGraphInformationPopupInfo;
 class SGraphNode_CustomNode : public SAnimationGraphNode
     SLATE_BEGIN_ARGS(SGraphNode_CustomNode) {}
     void Construct(const FArguments& InArgs, UAnimGraphNode_Base* InNode);
         // SNodePanel::SNode interface
     virtual void GetNodeInfoPopups(FNodeInfoContext* Context, 
         TArray<FGraphInformationPopupInfo>& Popups) const override;
     // End of SNodePanel::SNode interface
       . . .

custom editor module build file :

 using UnrealBuildTool;
 public class CoopGameEditor : ModuleRules
     public CoopGameEditor(ReadOnlyTargetRules Target) : base(Target)
         PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
             new string[] 
                 "AnimGraphRuntime", /* Engine Nodes */
             new string[] 
         PrivateIncludePathModuleNames.AddRange(new string[] { });
         DynamicallyLoadedModuleNames.AddRange(new string[] { });

Error Output:

 1>SGraphNode_CustomNode.cpp.obj : error LNK2019: unresolved external symbol "public: void __cdecl SAnimationGraphNode::Construct(struct SAnimationGraphNode::FArguments const &,class UAnimGraphNode_Base *)" (?Construct@SAnimationGraphNode@@QEAAXAEBUFArguments@1@PEAVUAnimGraphNode_Base@@@Z) referenced in function "public: void __cdecl SGraphNode_CustomNode::Construct(struct SGraphNode_CustomNode::FArguments const &,class UAnimGraphNode_Base *)" (?Construct@SGraphNode_CustomNode@@QEAAXAEBUFArguments@1@PEAVUAnimGraphNode_Base@@@Z)
