Expression must be a modifiable lvalue (error)

ProvideContext is a const function, and thus cant alter member variables. You’ll probably have issues with your FoundActor too

why am I getting this error? (Expression must be a modifiable lvalue)

I cant Equal any value, every value every time I get this error.


the Code :

.h :

#pragma once
   #include "CoreMinimal.h"
   #include "UObject/ObjectMacros.h"
   #include "EnvironmentQuery/EnvQueryContext.h"
   #include "GetPlayerContext.generated.h"
   class SHOOTEMUP_API UGetPlayerContext : public    UEnvQueryContext
   		virtual void ProvideContext(FEnvQueryInstance&    QueryInstance, FEnvQueryContextData&    ContextData) const;
   		APawn * FirstPlayerPawn;
   		AActor* FoundActor;
   		bool MyDoOnce = true;


#include "GetPlayerContext.h"
#include "Engine/World.h"
#include "GameFramework/Actor.h"
#include "AITypes.h"
#include "AIControllerV1.h"
#include "Runtime/Engine/Classes/Kismet/GameplayStatics.h"
#include "EnvironmentQuery/Items/EnvQueryItemType_Actor.h"
#include "EnvironmentQuery/Items/EnvQueryItemType_Point.h"
#include "EnvironmentQuery/EnvQueryManager.h"
#include "MyPawnShip.h"

	MyDoOnce = true;
	FoundActor = UGameplayStatics::GetActorOfClass(GetWorld(), AMyPawnShip::StaticClass());


void UGetPlayerContext::ProvideContext(FEnvQueryInstance& QueryInstance, FEnvQueryContextData& ContextData) const
	Super::ProvideContext(QueryInstance, ContextData);
	if (MyDoOnce)
		AAIControllerV1* AICon = Cast<AAIControllerV1>((Cast<AActor>((QueryInstance.Owner).Get())->GetInstigatorController()));
		MyDoOnce = fasle;

	if (FoundActor)
		//Set the context SeeingPawn to the provided context data
		UEnvQueryItemType_Actor::SetContextHelper(ContextData, FoundActor);

I think im blind, lol.

thanks, bro for the answer and fast replay.
