The damage meter, also called the damage counter, player display, or HUD, among other names, is a UI element in the Super Smash Flash series displayed during gameplay that presents basic information and status for each player at a glance. True to its name, the meter most prominently keeps track of a player's damage, though other statistics are generally shown here as well.
The damage meter displays, at the bottom of the screen, the damage percentage a player has accumulated, as well as their number of stocks remaining. In a time match, the damage meter will also show when a player wins or loses a point. In Super Smash Flash, these are accompanied only by an icon of the character, while in Super Smash Flash 2 they are superimposed over a background featuring the character's name, and portrait and series symbol. If the player uses a name, it will appear instead of the name of the character.
In SSF2, damage meters become translucent if a character goes behind them. The damage percentage itself changes color when more damage is accumulated. At low percentages, the value is white, but gradually turns pink and becomes reddish. A player's damage percentage will disappear if they are KO'd, and the meter itself will disappear if they lose all of their stocks. The damage meter has an option that displays scores during matches, which can be turned on or off in the Rules menu.
Additionally, the background of a player's damage meter in SSF2 is colored depending on their controller port: for human players, Player 1 is red, Player 2 is blue, Player 3 is yellow, and Player 4 is green, while CPUs are generally a gray color.
