It's a small HUD (just a primis), which is the button that turns on and off the "bumpdetector".
For those who do not know what is a "bumpdetector", it is a script placed into a object to be worn, the whose purpose is to inform you if someone try to shove you.
In our case the script is activated with a click on the HUD that represents the button.
When the script is actived, the button turns red and if someone try to shove you, you can read infos in local chat that showing you the object name and the name of its owner.
A second click disables the script, the button changes to white and you will not receive any info anymore, until when you'll decide to activate it again.
The Hud detects the objects collision on any viewer, if you use Firestorm you have an additional option
for detect push by script only, too.
You can active this option from:
Avatar -> Preferences -> Notification -> Objects & Scripts
and checking:
Report collisions notifications to script on channel -25000
- Detects collisions
- Detects shove by script ( on Firestorm only )
