Objective Waypoint System (C++ Plugin)

Blueprint only Project

Waypoint component is the main component of this plugin which you have to add to your player character or pawn. To add the component, select it from Components tab.

C++ Project

For C++ users, you have to first add plugin dependency in your Build.cs file like below:

PrivateDependencyModuleNames.AddRange(new string[] { "ObjectiveWaypointSystem" });

Then in your character or pawn header file, add the component. Here is an example:

class UWaypointComponent;

UCLASS()
class YOURPROJECTNAME_API AYourCharacter : public ACharacter
{
	GENERATED_BODY()

protected:
	
	UPROPERTY(VisibleAnywhere, BlueprintReadOnly)
	TObjectPtr<UWaypointComponent> WaypointComponent;

public:

	AYourCharacter();
};

Then in your source file (.cpp) create your constructor and add the following.

#include "WaypointComponent.h"

AYourCharacter::AYourCharacter()
{
	WaypointComponent = CreateDefaultSubobject<UWaypointComponent>(TEXT("WaypointComponent"));
}

Component settings

After adding the component, you can adjust it's settings from the details panel.
