PlayerStats will show health data for all nearby players within a given range of you. It allows you to configure various health and healthpercentage levels with customizable levels of criticality.

As for coloring, the most critical level wins. In other words, if your health is considered critical, but your health percentage is Medium, then stats are colored with critical coloring.

if your health percentage is critical, but your health level indicates it should be normal then the coloring will be critical.

Default color levels are from Normal to Critical:
* Green
* White
* Yellow
* Red

Various settings available

PlayerStatUpdateInterval
How often to update. This value represents frames, so if you're getting 30 FPS and the value is 30, you'll update every second. The higher your FPS, the more often this will update. I.E. 90 FPS = 3 updates by default (90/30 = 3). You can reduce overhead by increasing the value, but if your value is 90 and you're getting 30FPS you'll get an update ever 3 seconds. Trade off between performance and quick updates.
