Two Avatars on single prim
Ever wondered how to make two or more avatars to sit on single prim, to save prim amount on a furniture?
You need two kinds of scripts; the master (which calculates avatars sitting down and standing up) and a slave script for each additional avatar.
This is a modification of Pale Janus's script, originally posted here: OsGrid
Here are the basic scripts: modified for two avatars on single prim
MASTER <lsl> integer lastnum; key firstavatar; key secondavatar; string animation; integer num; integer firstnum; integer secondnum; integer originalprims;
//NOTE: An avatar is a CHILD prim, if you wish to move it after it has sat down, you need to know what her prim number is and use llSetLinkPrimitiveParamsFast to move her // October 5th 2013 Pale Janus & Cay Trudeau
default {
on_rez(integer flag) { do { llResetScript(); } while (TRUE); }
state_entry()
{
animation = llGetInventoryName(INVENTORY_ANIMATION,0);
llSitTarget(<1,1,1>, llEuler2Rot( <0 * DEG_TO_RAD, 0 * DEG_TO_RAD, 0 * DEG_TO_RAD> ) ); // there has to be something as sit target here, or else llSetLinkPrimitiveParamsFast fails
llSetSitText("Sit");
llSetClickAction(CLICK_ACTION_SIT);
lastnum=llGetNumberOfPrims();
originalprims=llGetNumberOfPrims();
llSetCameraEyeOffset(<-1, 0, 1> * <0.0, 0.0, 0.0, 0.0>);
llSetCameraAtOffset(<3, 0, 1> * <0.0, 0.0, 0.0, 0.0>);
}
changed(integer change)
{
if ( change & CHANGED_REGION_START) do { llResetScript(); } while (TRUE);
if (change & CHANGED_LINK)
{
num = llGetNumberOfPrims();
// Below is where all the magic happens
if (num > originalprims) // New avatar sitting down
{
if (num > originalprims && num < originalprims + 2) // 1st avatar sitting
{
firstnum = llGetNumberOfPrims();
firstavatar = llGetLinkKey(firstnum); //the avatar's UUID (cannot use llGetKey(llAvatarOnSitTarget) bc two avatars)
llRequestPermissions(firstavatar,PERMISSION_TRIGGER_ANIMATION);
//This is where we determine the avatar's sitting position
llSetLinkPrimitiveParamsFast(firstnum,[PRIM_POS_LOCAL,<0.0, -0.8, 0.2>,PRIM_ROT_LOCAL,ZERO_ROTATION]); // < -front + back , -right + left, -down + up >
llSitTarget(ZERO_VECTOR,ZERO_ROTATION); //releasing the sit target for next avatar
lastnum = firstnum;
}//1st avatar sitting end
if ( num > originalprims + 1 )// second avatar sitting
{
secondnum = num;
lastnum = secondnum; // Cay added this
llMessageLinked(LINK_THIS,200,(string)secondnum,""); //sends key
}//second avatar sitting end
} // (num > originalprims && num < originalprims + 2) end
else if (num < lastnum) //standing up ( I think this requires change upon the lastnum when the avatar sits, although it is mentioned at the bottom
