Caveats
Examples
default
{
state_entry()
{
llSitTarget(<0.0, 0.0, 1.0>, ZERO_ROTATION); //The vector's components must not all be set to 0 for effect to take place.
}
}
Useful Snippets
//Sets / Updates the sit target moving the avatar on it if necessary.
UpdateSitTarget(vector pos, rotation rot)
{
llSitTarget(pos, rot);//Set the sit target
key user = llAvatarOnSitTarget();
if(user)//true if there is a user seated on the sittarget, if so update their position
{
vector size = llGetAgentSize(user);
if(size)//This tests to make sure the user really exists.
{
//We need to make the position and rotation local to the current prim
rotation localrot = ZERO_ROTATION;
if(llGetLinkNumber() > 1)//only need the local rot if it's not the root.
localrot = llGetLocalRot();
pos.z += 0.4;
integer linkNum = llGetNumberOfPrims();
do{
if(user == llGetLinkKey( linkNum ))//just checking to make sure the index is valid.
{
llSetLinkPrimitiveParams(linkNum,
[PRIM_POSITION, ((pos - (llRot2Up(rot) * size.z * 0.02638)) * localrot) + llGetLocalPos(),
PRIM_ROTATION, rot * localrot / llGetRootRotation()]);
jump end;//cheaper but a tad slower then return
}
}while( --linkNum );
}
else
{//It is rare that the sit target will bork but it does happen, this can help to fix it.
llUnSit(user);
}
