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; vector localpos = ZERO_VECTOR; if(llGetLinkNumber() > 1)//only need the local rot if it's not the root. { localrot = llGetLocalRot(); localpos = llGetLocalPos(); } 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) + localpos, 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); } } @end; }//Written by Strife Onizuka, size adjustment provided by Escort DeFarge
