============= IN-HUD HEALTH RACE BAR ==============
The top bar in the HUD, directly below the player character on screen is the nUI Health Race bar (which is only visible when you are targeting a player or mob that you can attack). This bar is made up of four components... the bar itself, a player health button at the top left, a target health button at the top right and a relative health button (the race button) at the bottom center. In short, this single bar gives a quick view of the player's health and target's health relative to their individual maximums as well as their percent health relative to one another. I highly recommend you give this bar a try for PvP as it provides you a powerful single reference to measure your progress against your opponent.
At full health, the player health button is to the far left edge of the bar and the target health button to the far right... as either the player's health or the target's health declines, their respective buttons will move toward the center of the bar. The first one to the middle loses! ~smile~ At a glance, both buttons show their health as a percentage of their maximums.
The key button is the relative health button at the bottom of the bar. This button measures the relative health of the player (as a percent of the player's maximum) as compared to the relative health of the target (as a percent of the target's maximum). When the button is at the center of the bar, then the player and target have the same relative health. If the player's percentage of their maximum health is higher than the target's, the relative health button will move left of center. If the target's health is higher as a percentage of its maximum as compared to the player's percentage of total health, the button moves to the right.
The further left of center the bottom button moves, the higher the player's health relative to the target's and visa versa. A relative health of 100 means the player is at full health and the target at or near death in which case the bottom button will be to the far left of the bar and the bar color will be bright green. A relative health of -100 means the target is at full health the player at or near death and the bar will be colored bright red. If both the target and player are at near equal health as a percentage of their maximums, the button will be at the center and the bar colored yellow.
