class Snake{ public: Snake(int l_blockSize); ~Snake(); // Helper methods. void SetDirection(Direction l_dir); Direction GetDirection(); int GetSpeed(); sf::Vector2i GetPosition(); int GetLives(); int GetScore(); void IncreaseScore(); bool HasLost(); void Lose(); // Handle losing here. void ToggleLost(); ...
