Is Avatar Facing Target?
Hello! Old SL user, but was away for a long time! I hadn't used SL since around the time that shadows were made more dynamic, and came back to many wonderful changes! I'm working on a script for wands, and for the particle effect to look right for some spells, the avatar needs to be facing its target. I'm sure there's some way of doing that by checking the rotation of the avatar to the relativity of the target, but I don't know the logic to make that happen. Of course I'm sure that wouldn't work
vector avPos = llGetPos();rotation avRot = llGetRot(); // some of the previous posts deal with the avatar rotation which is worth some considerationsvector targetPos; // find this with sensor or whatever// Now compute two unit vectorsvector facing = llRot2Fwd( avRot);vector target = llVecNorm( targetPos - avPos);// finaly compute the dot product of both vectorsfloat dp = facing*target; // ( this is the same as cosinus to the angle between the vectors!! look it up:) )if ( dp == 1.00 ) // you are
