// Drink Script - makes it seem like beer is being drunk
// :CODE:
//: LICENSE: CC-0 (Open Source)
//: DESCRIPTION:
// 1) Make a cylinder and a glass, lets say, of beer.  Texture the cylinder to look like the beer liquid - mostly brown, with white foam at one end, and put white on the top of the cylinder. Put this cylinder inside the beer glass.    Or make a tapered cylinder and and fit it into another glass.
// 2) Link the glass and any other prims to the beer cylinder. The cylinder need to be the last thing clicked to make it the root prim.  
//  This script currently requires there be AT LEAST 2 prims.  Otherwise LINKNUM must be a 0 for a single prim, or the number of the prim that is the beer prim.
// 3) Add the script below to the root prim.     When reset, the beer should dissappear,   and appear to fill back up.
// 4) type this in chat:
//   /942 Drink
//  The beer will decrease by 10% rthwn empty, it shudl announce with a whsiper that "XX, your glass is empty."

// globals
float drink_left;
integer LINKNUM = 1;  // Assumes that the cylinder that is being drunk is the root prim.
string DECREASE_FOOD = "Drink";
float X = 1.0;
float Y = 1.0;
float  Z = 1.0; // the length of the cylinder

fill()
{
    float i = 0 ;
       
    //loop around cutting the length to fuill
    while (i < Z)
    {
        llSetLinkPrimitiveParamsFast(LINKNUM,[PRIM_SLICE, <0, i,0>]);           
        llSleep(.1);
        i += .020 ;            // ad 1/10 of a Z each loop
    }
    drink_left = 1; // 100%
