// :DESCRIPTION:
// the HUD
// :CODE:

///Putting it together:
//put the Giant Hammer script in a hammer shaped object, maybe adjust params depending on hammer size, centre of rotation etc.
//put the Hammer in the Bullet object (any prim will do, but I use a tiny invisible one!) and add the Bullet script
//put the Bullet (now containing the Hammer) in the HUD object

// When you wear the HUD it will tell you what to do.


// Project: Hammer thrower
// Script: Hammer launcher
// Get avatar name, or target all.
// Rez objects giving them target avatar name
// add channel command

//Simple OpenSource Licence (I am trusting you to be nice)
//1.  PLEASE SEND ME UPDATES TO THE CODE
//2.  You can do what you want with this code and object including selling it in other objects and so on. 
//You can sell it in closed source objects if you must, but please try to send any updates or
//improvements back to me for possible inclusion in the main trunk of development.
//3.  You must always leave these instructions in any object created; notecard written; posting to
//any electronic medium such as Forum, Email &c. of the source code & generally be nice (as
//already requested!)
//4.  You must not claim that anyone apart from sparti Carroll wrote the original version of this software.
//5.  You can add and edit things below =THE LINE= but please try  to keep it all making sense.
//Thank you for your co-operation
