UDebugDrawComponent

Helper class to derive from to use debug draw delegate functionalities (i.e. DrawDebugLabels) The class will take care of registering a delegate to the UDebugDrawService and draw all FText3d provided by the scene proxy. This functionality only requires the derived classes to override `CreateDebugSceneProxy_.

It is also possible to add text from other sources of data from the scene proxy but that requires a few extra steps:

• create a class that inherits from `FDebugDrawDelegateHelper_

• override `DrawDebugLabels_

• add a method to be able to populate the source data from the scene proxy ex: class FMyDelegateHelper : public FDebugDrawDelegateHelper { public: void SetupFromProxy(const FMySceneProxy* InSceneProxy) { <collect data>=""> }; protected: virtual void DrawDebugLabels(UCanvas* Canvas, APlayerController*) override { <draw data>=""> }; private: TArray<FVector> SomeData; };

• Within the component inheriting from `UDebugDrawComponent_

• add a property of that new helper type in the component inheriting from `UDebugDrawComponent_

• override `GetDebugDrawDelegateHelper_ to return that new member as the new delegate helper to use

• and then use it in `CreateDebugSceneProxy_ before returning the created proxy. ex: class MyDebugDrawComponent : public UDebugDrawComponent { protected: virtual FDebugRenderSceneProxy* CreateDebugSceneProxy() override { FMySceneProxy* Proxy = new FMySceneProxy(this); MyDelegateHelper.SetupFromProxy(Proxy); return Proxy; } virtual FDebugDrawDelegateHelper& GetDebugDrawDelegateHelper() override { return MyDelegateHelper; } private: FMyDelegateHelper MyDelegateHelper; }
