Library: Animated Buttons

I thought about some nice ways to animate buttons at HUDs or other objects like vendors
and figured out a few ways to do.
Depending on what type of button it can be scaled, rotated or animated more advanced using the llSetTextureAnimation function and custom texture for.
First of hopefully more coming scripts will simply scale a touchd button and fades out befor changing back to default size and transparency.

Feel free to improve, upgrade a/o downgrad the script to your needs ^

 // button scale script
// by revochen  June/1/2008

 

// to use for HUD or other objects buttons

// by sending link messages it may interact with other scripts




vector button_size=<0.01,.05,.05>; // default button size
list buttons=[2,3,4,5]; // list of buttons/prim numbers for

scale(integer prim_nr) // global prim scale function

{
    float count;
    float alpha;
    for(count=0; count<.03; count+=.01)
    {
        alpha+=.2;
        
        llSetLinkPrimitiveParams(prim_nr,

            [PRIM_SIZE,<button_size.x,button_size.y+count,button_size.z+count>,

             PRIM_COLOR,ALL_SIDES,<1,1,1>,1.0-alpha]);
    }
    llSetLinkPrimitiveParams(prim_nr,[PRIM_SIZE,button_size,PRIM_COLOR,ALL_SIDES,<1,1,1>,1]);
}


default
{


    state_entry()
    {
        integer count;
        integer max=llGetListLength(buttons);
        for(count=0; count<max; ++count)
        {
            llSetLinkPrimitiveParams(llList2Integer(buttons,count),[PRIM_SIZE,button_size]);
        }
     }

    touch_start(integer total_number)
    {

        //uncomment next line to make it only for owner usable

        if(llDetectedKey(0)!=llGetOwner()) return;

        integer link_nr=llDetectedLinkNumber(0);
        //llSay(0,(string) link_nr); // uncomment this line to find out a buttons link number

       
        if(llListFindList(buttons,(list)link_nr)!=-1)

        {

            // send a link message to interact with other scripts

            // and trigger other main functions for a specific button

           // llMessageLinked();

            scale(link_nr);

            // maybe you want sound for the buttons

            // llPlaySound();

         }
    }
}

I'm likin' it... pretty neat.
