“Health bar” redirects here. For the cereal bar, see Energy bar.
Health is an attribute in a video game or tabletop game that determines the maximum amount of damage or loss of stamina that a character or object can take before dying or losing consciousness. In role-playing games, this typically takes the form of hit points (HP), a numerical attribute representing the health of a character or object. The game character can be a player character, a boss, or a mob. Health can also be attributed to destructible elements of the game environment or inanimate objects such as vehicles and their individual parts. In video games, health is often represented by visual elements such as a numerical fraction, a health bar or a series of small icons, though it may also be represented acoustically, such as through a character’s heartbeat.Mechanics
In video games, as in tabletop role-playing games, an object usually loses health as a result of being attacked. Protection points or armor help them to reduce the damage taken. Characters acting as tanks usually have more health and armor. In many games, particularly role-playing video games, the player starts with a small amount of health and defense points, but can increase them by gaining the required amount of experience points and raising the character’s level.
In game design, it is considered important to clearly show that the player’s character (or other object that they control) is losing health. In his book Level Up!: The Guide to Great Video Game Design, game designer Scott Rogers wrote that “health should deplete in an obvious manner, because with every hit, a player is closer to losing their life”. As examples of visualizing health loss, Rogers cited Arthur of Ghosts ‘n Goblins, who loses a piece of armor with each sustained hit, as well as the cars in the Grand Theft Auto series, in which smoke begins to flow from the hood after the car takes a significant amount of damage.
The use of health points simplifies the game development process (since developers do not need to create complex damage systems), allows computers to simplify calculations associated with the game, and makes it easier for the player to understand the game. However, more complex and realistic damage systems are used in a number of games. In Dwarf Fortress, instead of health points, dwarves have separate body parts, each of which can be damaged. The Fallout games use health points, but allow characters to inflict damage to different parts of the enemy’s body, which affects gameplay. For example, if a leg is injured, the character can get a fracture, which will reduce their movement speed, and if their arm is injured, the character can drop their weapon. Health can also serve as a plot element. In Assassin’s Creed, if the protagonist takes too much damage, thus departing from the “correct” route, the game ends and returns the player to the nearest checkpoint.
In some games such as The Legend of Zelda and Monster Hunter, only the player’s health points are visible. This is done so that the player does not know how many blows still need to be delivered, which makes the game less predictable. Contrariwise, other games such as the Street Fighter series have both the player’s and the opponent’s health meters clearly visible, which allows the player to understand how successful their combat strategy is and how many remaining blows need to be inflicted on the enemy.Regeneration
Players can often restore a character’s health by using various items such as potions, food or first-aid kits. In role-playing video games, the player often can also restore a character’s health by visiting a doctor or resting at an inn. A number of games incorporate a mechanic known as “life steal” or “life leech”, which allows a character to restore health by siphoning it from an enemy. Methods for replenishing health differ from each other and are dependent on the game’s aliran. In more dynamic action games, it is important to quickly restore a character’s health, while role-playing games feature slower-paced methods of health restoration to achieve realism.
A number of games incorporate a regeneration system that automatically replenishes health if the character does not take damage. This makes the game easier to play by giving the player the opportunity to restore the character’s health after a difficult battle. This system may allow the player to safely run through dangerous parts of the game without consequence.Presentation
A health bar, a possible representation of the health of a character.
The health indicator can be represented in various ways. The most basic forms are fractions and health bars, as well as various icons such as hearts or shields. The indicator can be combined with other elements of the game interface. Doom uses a character portrait located at the bottom of the screen as such an indicator. If the hero takes damage, his face will be covered with blood. The health point indicator can also be part of the character. In Dead Space, it is located on the main character’s costume. In Trespasser, it is represented as a tattoo on the main character’s chest. In Half-Life: Alyx, a VR game, the indicator is located on the back of the player’s non-dominant hand, requiring the player to physically look at their tracked hand to check their health. The character’s condition can be conveyed through sound. In Dungeons of Daggorath, the frequency of the player character’s audible heartbeat is dependent on how much damage has been received. Silent Hill uses a similar system, but transmits the heartbeat via vibrations from the DualShock controller.
The player character’s health point indicator often occupies a significant position in the game’s heads-up display. In The Legend of Zelda, it occupies one third of the entire display. However, a number of games do without such an indicator. In the Super Mario series, the player character initially only has one health point, and the character’s appearance is used to signify the number of health points; if the character collects a Super Mushroom, they grow in size and gain an additional health point. In a number of first-person shooters, such as Call of Duty or Halo, the numerical value of the character’s health points is hidden from the player. However, when the player character receives a large amount of damage, the game screen (or the part of the screen to which damage was dealt) is painted red, often including drops of blood, which simulates the effect of real-life injury. As health is restored, these effects gradually disappear.HistoryHit points
The term “hit points” was coined by Dungeons & Dragons co-creator Dave Arneson. While developing the tabletop role-playing game Dungeons & Dragons with Gary Gygax based on the latter’s previous game Chainmail, Arneson felt that it was more interesting for players to manage small squads than a large army. This also allowed them to act out the role of each squad member. However, this approach had one drawback: according to the rules of Chainmail, the player rolls the dice during each battle, and depending on the number rolled, the character either kills the enemy or is killed. Because players did not want to lose the characters they had become accustomed to, Arneson created a “hit point” system based on similar mechanics previously used in the wargames Don’t Give Up the Ship and Ironclads. According to this system, each character has a certain number of hit points, which decreases with each blow dealt to them. This allows the character to survive several hits from an enemy.
Some of the first home computer games to use hit points are Rogue (1980), in which health is represented by a fraction, and Dungeons of Daggorath (1982), which includes an audible heartbeat influenced by the player character’s condition. Action games also began moving away from one-hit deaths to health systems allowing players to take multiple hits, such as SNK’s arcade shoot ’em up game Ozma Wars (1979) numerically representing an energy supply that depletes when taking hits and Mattel’s Intellivision game Tron: Deadly Discs (1982) allowing players to take multiple hits at the cost of reducing maneuverability.Health meter
Before the introduction of health meters, action video games typically used a lives system in which the player could only take damage once, but could continue the game at the expense of a life. The introduction of health meters granted players the right to make mistakes and allowed game developers to influence a game’s difficulty by adjusting the damage an enemy character inflicts.
