I’m trying to get my player to move forward when I press te left and right mouse button in C++, but I don’t know how to code 2 buttons to be pressed at the same time in C++.
I can do it in Blueprint, so I know it is possible, but I want it in C++ for optimization.
In the Blueprint did I call the Left Mouse Button for LMB and the Right Mouse button for RMB and did set the value in the Project setting to 0.5.
Can someone please help me?
in your blueprints you ware using AXIS instead Action (buttons) anyway in C++ should be like this:
InputComponent->BindKey(EKeys::LeftMouseButton, IE_Pressed, this, &AYourActor::LeftButtonFunction);
you can put that in the beginplay of your actor with the other bindings)
LeftButtonFunction is the function you want to run when leftMouseButton is PRESSED
do the same for rightMouseButton and another binded function
same for release (IE_Released)
then you can have 2 bool variables: LMB and RMB…
in the pressed functions set the corresponding to true and in the release to false.
Then the condition is if (RMB && LMB) to add movement input
first I get an error in on the “BindKey” in the cpp file, how to I fix that?
Second, How do I set a bool in c++?
bool RMB;
I don’t know how is your code. And seems you don’t know C++
Why do you want to do this in C++?
Hello! As @eldany.uy suggested, you have to use a Pawn or Character inherited class, for this example I used AMyCharacter which inherits from ACharacter.
The header looks something like this
// Fill out your copyright notice in the Description page of Project Settings.
#pragma once
#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "MyCharacter.generated.h"
UCLASS()
class TP_FIRSTPERSON_API AMyCharacter : public ACharacter
{
GENERATED_BODY()
public:
// Sets default values for this character's properties
AMyCharacter();
protected:
// Called when the game starts or when spawned
virtual void BeginPlay() override;
void OnLeftMouseButtonPressed();
void OnLeftMouseButtonReleased();
void OnRightMouseButtonPressed();
void OnRightMouseButtonReleased();
bool LeftMouseButtonIsBeingPressed;
bool RightMouseButtonIsBeingPressed;
public:
// Called every frame
virtual void Tick(float DeltaTime) override;
// Called to bind functionality to input
virtual void SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) override;
};
Then, you have to bind the action of pressing and releasing a mouse button to this functions we defined (OnLeftMouseButtonPressed(), OnLeftMouseButtonReleased(), OnRightMouseButtonPressed(), OnRightMouseButtonReleased()). We will do it on the SetupPlayerInputComponent function.
// Called to bind functionality to input
void AMyCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
Super::SetupPlayerInputComponent(PlayerInputComponent);
PlayerInputComponent->BindAction("LeftMouseButton", IE_Pressed, this, &AMyCharacter::OnLeftMouseButtonPressed);
PlayerInputComponent->BindAction("LeftMouseButton", IE_Released, this, &AMyCharacter::OnLeftMouseButtonReleased);
PlayerInputComponent->BindAction("RightMouseButton", IE_Pressed, this, &AMyCharacter::OnRightMouseButtonPressed);
PlayerInputComponent->BindAction("RightMouseButton", IE_Released, this, &AMyCharacter::OnRightMouseButtonReleased);
}
If you notice, instead of using BindKey I’m using BindAction, I’ll tell you in a bit, what to do with that. After this, we have to define what will those functions actually do, and that is set as true or false the booleans we defined in the header (LeftMouseButtonIsBeingPressed, RightMouseButtonIsBeingPressed):
void AMyCharacter::OnLeftMouseButtonPressed()
{
LeftMouseButtonIsBeingPressed = true;
}
void AMyCharacter::OnLeftMouseButtonReleased()
{
LeftMouseButtonIsBeingPressed = false;
}
void AMyCharacter::OnRightMouseButtonPressed()
{
RightMouseButtonIsBeingPressed = true;
}
void AMyCharacter::OnRightMouseButtonReleased()
{
RightMouseButtonIsBeingPressed = false;
}
On the Tick, we will check if the left and right buttons are being pressed, and if they do, let’s move. (for this example I just set it to move on the actor forward vector)
void AMyCharacter::Tick(float DeltaTime)
{
Super::Tick(DeltaTime);
if (LeftMouseButtonIsBeingPressed && RightMouseButtonIsBeingPressed)
{
AddMovementInput(GetActorForwardVector());
}
}
Now if you followed my steps, it should compile and let you use the editor, once inside the Editor, go into project settings, Input, and into Action Mappings, press the “+” sign right next to it, then add the two inputs we told the cpp we had (LeftMouseButton and RightMouseButton), and finally make so that the LeftMouseButton gets called with the LeftMouseButton, and the same for the RightMouseButton.
I did try your code, but it gives me compiling errors,

How do I fis the errors?
I had the same problem when trying to implement @eldany.uy answer, what I did was change the BindKey for BindAction, and instead of doing the bindings on the BeginPlay, I did it on the SetupPlayerInputComponent. I edited my previous response, you can check there if that solves those issues.
I used my code in my Player Controller like this:
InputComponent->BindKey(EKeys::Left, IE_Pressed,this,&AMyPlayerController_CPP::setLEFTOn).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Left, IE_Released,this,&AMyPlayerController_CPP::setLEFTOff).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Right, IE_Pressed,this,&AMyPlayerController_CPP::setRIGHTOn).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Right, IE_Released,this,&AMyPlayerController_CPP::setRightOff).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Up, IE_Pressed,this,&AMyPlayerController_CPP::setUPOn).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Gamepad_DPad_Up, IE_Pressed,this,&AMyPlayerController_CPP::setUPOn).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Up, IE_Released,this,&AMyPlayerController_CPP::setUPOff).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Down, IE_Pressed,this,&AMyPlayerController_CPP::setDOWNOn).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Gamepad_DPad_Down, IE_Pressed,this,&AMyPlayerController_CPP::setDOWNOn).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Down, IE_Released,this,&AMyPlayerController_CPP::setDOWNOff).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Android_Back, IE_Pressed,this,&AMyPlayerController_CPP::quitGame).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::K, IE_Pressed,this,&AMyPlayerController_CPP::quitGame).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::Q, IE_Pressed,this,&AMyPlayerController_CPP::quitGame);
InputComponent->BindKey(EKeys::LeftMouseButton,IE_Released,this,&AMyPlayerController_CPP::releaseMouseButton).bExecuteWhenPaused=true;
InputComponent->BindKey(EKeys::P, IE_Pressed,this,&AMyPlayerController_CPP::SetPauseBP).bExecuteWhenPaused = true;
InputComponent->BindKey(EKeys::Gamepad_FaceButton_Bottom,IE_Pressed,this,&AMyPlayerController_CPP::SetPauseBP).bExecuteWhenPaused=true;
and worked flawless maybe is because of the UE version? I use 4.27
Oh I see…I am binding generic Inputs (prebuilt actions like A,B,C keys…) not ACTIONS defined in settings.
Sorry for that

Those errors you are showing here, don’t have anything to do with these bindings (as I am aware). They seem to be related to a class that overrides functions not defined in its parent class. Try double-clicking the error, it’ll jump to the file with those issues.
The last one (identifier “something” is undefined) is a common error when you are using a class that is not included in the class that you are using it.
Your Visual Studio screenshot is only showing IntelliSense errors, which you can ignore. In the Error List, change the “Build + IntelliSense” dropdown to “Build Only” and then send the screenshot that shows all of the error list.
