Health (gaming)

Health is a game mechanic used in tabletop role-playing games and video games to give value to characters, enemies, NPCs, and related objects. This value can either be numerical, semi-numerical as in hit/health points, or arbitrary as in a life bar.

Hit points

Hit points, also known as health points (or HP), damage points, heart points, or just health (among other synonyms), is a finite value used to determine how much damage (usually in terms of physical injury) a character can withstand. When a character is attacked, or is hurt from a hazard or fall, the total damage dealt (which is also represented by a point value) is subtracted from their current HP. Once their HP reaches 0, the character will be unable to fight. In role-playing games, health is often abbreviated by two letter initialisms such as HP.

In some role-playing games such as Dungeons & Dragons, a player character's hit points are determined by character level. The hit points of monsters are decided by rolling "Hit Dice". Characters with high constitution will have an advantage when hit points are assigned. A character whose hit points are reduced to zero is considered dead or incapacitated. Other games sometimes lack levels, hit points, or both.

In certain editions of the game, player characters with 0 HP are not dead, but rather knocked unconscious. Within the range of -1 and -9, they are considered to be mortally wounded and dying, and their HP will steadily drop until it is stabilized. At -10, the character dies. Depending on the rules, a character who suffers 50+ points of damage from a single blow may die as a result of "Death from Massive Damage".[1] The player must then make a "saving throw" of the dice in hope of countering the damage. Failure to do so results in the characters dying, regardless of their remaining HP.

In many role-playing video games, the objective is to deplete the hit points of enemies while maintaining the health of player characters. Hit points can typically be refilled by using a restorative item, staying the night at an "inn", or utilizing healing magic. Generally, characters are killed or rendered unconscious as soon as their hit points reach 0.

History

Dungeons & Dragons co-creator David Arneson described the origin of hit points in a 2002 interview. When Arneson was adapting the medieval wargame Chainmail to a fantasy setting, a process that with Gary Gygax would lead to the game Dungeons & Dragons, he saw that the emphasis of the gameplay was moving from large armies to small groups of heroes and eventually to the identification of one player and one character that is so essential to role-playing as it was originally conceived. Players became attached to their heroes and did not want them to die every time they lost a die roll. Players were given multiple hit points which were then incrementally decreased. Arneson took the concept, along with armor class, from a set of a naval American Civil War game's rules.[2]

Life bar

A health or life bar is used to display a character's health in many video games. A typical life bar is a horizontal rectangle which begins full of color. If damage is taken or mistakes are made, the colored area gradually reduces (some also change colour, typically from green to yellow to red, as health is reduced). When the bar is completely emptied, the result is game over (death, being knocked out, etc.). The first video game to use a life meter was Dragon Buster, a 1984 video game that referred to the meter as "Vitality" in the game.[3] There have since been many variations on the life bar:

In Street Fighter and other fighting games, the bar does not instantly immediately decrease when damage is taken. Instead, an area representing the damage is marked in red, and the health lost quickly drains away. This is useful in assessing the amount of damage caused by an attack.

Some games use an incremental bar, composed of many smaller bars. Each attack will remove a certain number of these bars. This system is used in the Mega Man and Metroid series.[4]

Some video games also feature a recharging health bar (sometimes depicted as an energy shield). In these games, the player character cannot usually take as much damage as a player with a traditional life bar, but health regenerates over time (usually initiating regeneration when the player avoids being damaged for a period of time). Notable examples of this are the Hydlide series, Ys series,[5][6] Halo series, Call of Duty series, Destroy All Humans!, Gears of War, Tom Clancy's Rainbow Six Vegas, Tom Clancy's Splinter Cell Double Agent, and Red Steel. Some games increase the maximum amount of health a player can carry as they progress through the game.

Icon-based health

Icons are another method for measuring health. Some games such as Prince of Persia, DuckTales, and Mr. Nutz, which use a number of icons to represent health units; every hit against the player character will always decrease health by one icon or unit at a time. In other games a hit may reduce health by one icon or unit, a fraction of one icon, or many icons at once, depending on how powerful the hit is, and the strength of the character's defence of armour. In the The Legend of Zelda series of video games, the player's health is represented as small hearts, which are located near the top of the screen.[4] Weak attacks against the player will take only a fraction of a heart, usually one-quarter or one-half, and stronger attacks may take many whole hearts at once. Several games make use of similar heads-up displays. Super Mario Bros. 2 uses small red icons (in 16-bit versions of the game, they're changed to hearts) in the top left corner to designate how many hitpoints the player has remaining, and Bram Stoker's Dracula uses small flasks of liquid.

Other games, such as Deus Ex, show a HUD of a human body, which is green to begin with. As the player takes damage, the respective region of the body turns yellow, orange, red, and eventually disappears altogether. For the head and torso, this is fatal. For arms, this causes a significant decrease in weapon accuracy or damage (or a complete inability to use them), while such a damage for legs usually leads to a badly impaired movement. A similar system, but showing the player's current vehicle rather than a human body, is used in some simulation games such as Rogue Squadron.

Other variations

Recharging health

Some games use a system of recharging health (or regeneration), where health points are regained over a short period of time (usually minutes). This mechanic has its origins in action role-playing games of the 1980s, specifically the Hydlide and Ys series.[5][6] In the 2000s, the mechanic was popularized among first-person shooters by the Halo series, while action RPGs such as Fable have continued to utilize the mechanic.

Other games require the use of healing spells, skills, or items (such as potions, medicine, first aid kits, bandages, syringes, medical bags, herbs, and even food) to regain health. Many game systems incorporate both slow regeneration and instant-effect healing skills and items. Games often have items that recharge all or some of a character's health, but they may differ in that, some games allow the player character to collect and carry many items in an inventory and use them to recharge health at a later time when needed; while in other games the player character cannot carry items in such a way and items will recharge health immediately upon touching them or sometimes upon picking them up.

An increasingly common standard, standardized with the Call of Duty series, most of the Halo series, and many other shooter games, is a complete lack of any health-replenishing items—the wounded player is simply expected not to take damage by taking cover and wait (generally from 5–20 seconds) as his or her character recovers. Most of these games do not feature a health meter; the player judges his or her health from blood on the screen, heavy breathing, and other details.

Incremental health

In the Sonic the Hedgehog series, Sonic collects rings, which are used as Sonic's health indicator. They are shown as numbers at the upper left side of the screen. Whenever an enemy touches the player character, Sonic, all his rings scatter in many directions. If the player is fast enough, Sonic can reclaim some of the rings before they flicker and disappear. Sonic can be knocked out easily by his enemies when his ring total is at 0, at which point any further damage will kill him. Sonic's rings differ from most health mechanisms in that having multiple rings offers no extra protection; however many rings a player possesses, all will be lost with one hit. However, some newer Sonic games such as Sonic Blast, Sonic the Hedgehog, Sonic and the Secret Rings, Shadow the Hedgehog and Sonic Unleashed have attempted to increase the fairness of this system by having the player lose only a set number of rings per hit (usually ten or twenty), meaning that having more rings provides better protection.

Percentage meter

In the Super Smash Bros. series, instead of health bars featured in most fighting games, percentage meters are used. When attacking an opponent or being attacked by an opponent, the percentage meter rises based on the damage inflicted; as the percentage meter increases, the character gradually becomes easier to knock away with strong attacks, possibly getting knocked out of the arena and, thus, losing either a life or a point, depending on the mode of play.

Health represented without Heads-Up Display

In order to immerse the player in the gaming experience, some developers do away with the health bar (and other on-screen displays) completely and try to present a character's health in other ways, such as showing a character limping or displaying visible wounds when they are injured. Jurassic Park: Trespasser (1998) has no HUD and represents its player character's (Anne) health as a heart-shaped tattoo on her breast which fills up with red as the damage increases. When she dies, the heart has a chain around it. In the Resident Evil (1996–present) video games, health is shown both with the player character limping and pressing his/her wounds in pain, and with an EKG display in the inventory screen. Games such as Call of Duty 2 (2005) or Peter Jackson's King Kong: The Official Game of the Movie (2005) have no life bar; instead, the game uses the screen as health, and when the player gets hit, the screen flashes red, and in some games the vision will also becomes blurred in this condition (more damage indicated by a deeper red coloration). In some games, characters slouch over and breathe heavily as a result of low health when left idle; blood stains or wounds may also appear on characters to show they are injured. in Infamous, Blood splatters across the screen when Cole is damaged, more damage means More blood on the screen. Some third-person games such as Dead Space (2008) and Ghostbusters: The Video Game (2009) have health bars shown on the player model rather than in a HUD. They resemble ordinary health meters apart from being physically attached to the character's equipment.
