What is the best way to check the position of an avatar to an object and return a True or false bast on which side of the object the avatat is? Code snippets would be great if possible. Thanks.

Quick way: use a dot product between the forward vector and the direction to the avatar concerned. e.g. if you have a sensor() or touch_start() etc event, you can use something like this...
if ((llRot2Fwd(llGetRot()) * llVecNorm(llDetectedPos(0) - llGetPos())) > 0) {
llOwnerSay("In front of me");
}
I think there's a free door thing in my freebie box that illustrates this principle. |

got it to work for one door, how do I rotate the script so to speak so it checks top and bottom?
