However, a change needs to be made to the OnOverlapBegin and OnOverlapEnd functions.
In the source file for LightSwitchBoth, the constructor remains the same. UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Switch Variables") ** the desired intensity for the light */ ** Toggles the light component's visibility*/ Void OnOverlapEnd_Implementation(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex) Void OnOverlapEnd(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex) ** called when something leaves the sphere component */ Void OnOverlapBegin_Implementation(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult) Void OnOverlapBegin(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult) UFUNCTION(BlueprintNativeEvent, Category="Switch Functions") ** called when something enters the sphere component */ UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category="Switch Components") All Rights Reserved.Ĭlass _API ALightSwitchBoth : public AActor
LightSwitchBoth.h // Copyright 1998-2018 Epic Games, Inc. OnOverlapBegin and OnOverlapEnd are now BlueprintNativeEvents, and will show up in the category Switch Functions in the My Blueprint tab.ĭesiredIntensity is BlueprintReadWrite, and will show up in the category Switch Variables in the My Blueprint tab.ĭesiredIntensity is now EditAnywhere instead of VisibleAnywhere. The PointLightComponent and the SphereComponent are BlueprintReadOnly, and will show up in the category Switch Components in the My Blueprint tab. This header file is adapted from the C++ Only LightSwitch example to add the following functionality: To create the LightSwitchComponent, SphereComponent, DesiredIntensity variable, and OnOverlap function. You may find it helpful to first refer to the C++ Only LightSwitch example, to see how the header file and source file are set up This example will go over the UPROPERTY()Īnd UFUNCTION() specifiers that make LightSwitchBoth work as a template for the Blueprint that will derive from it.
While you couldĮxtend the LightSwitchCodeOnly class with a Blueprint, the components, variables, and functions created in that class would not be accessible to Blueprint graphs.

Most of the code setup in the LightSwitchBoth class is similar to the code in the C++ Only LightSwitch example. There are a number of specifiers that change how a C++ class interacts with the Blueprint system, and some of them will be highlighted in this example.įor the first section of the class setup, a class called LightSwitchBoth is created using the C++ Class Wizard. C++ classes can be extended with Blueprints, allowing programmers to set up new gameplay classes in code that can be built upon and changed with Blueprints by level designers.
