Unreal中Input的设定

首先在编辑器中，Settting->ProjectSettings->Input中设置

然后代码的

// Called to bind functionality to inputvoid AAvatar::SetupPlayerInputComponent(class UInputComponent* InputComponent){Super::SetupPlayerInputComponent(InputComponent);    InputComponent->BindAxis("Forward", this, &AAvatar::MoveForward);    InputComponent->BindAxis("Strafe", this, &AAvatar::MoveForward);}

void AAvatar::MoveForward(float amount){    if(Controller && amount)    {        FVector fwd = GetActorForwardVector();        AddMovementInput(fwd, amount);    }}void AAvatar::MoveRight(float amount){    if(Controller && amount)    {        FVector right = GetActorRightVector();        AddMovementInput(right, amount);    }}
