Basic movement controls for an AI.

Here's a list of some logic gates I've developed that will tell a AI where it is relative to a specified point. These are not complete scripts, but rather the "if-then" calculations that return values if a point is in front, behind, left, right, above, or below the bot's current location.


Using these logic gates I have made a vehicle which moves between 14 waypoints without colliding that has had an up-time of 8 days and counting without problems requiring the vehicle needing to be reset (can be found at the sim "This Land". I am using strings as the returned values for ease of readability, but it is probably more efficient to use integers in your actual code.


In front/behind logic gate.

        string direction;
        vector mydir=llRot2Fwd(llGetRot());
        vector tardir=llVecNorm(target-mypos);
        if(llVecMag(mydir + tardir) <1)
        {
            direction= "behind";
        }
        else
        {
            direction = "in front";
        }

left/right logic gate

        string direction;
        vector mydir=llRot2Fwd(llGetRot());
        vector tardir=llVecNorm(target-mypos);
        rotation test=llRotBetween(mydir,tardir);

        if(test.z>0)
        {
            direction="right";
            
        }
        else if(test.z<0)
        {        
            direction="left";
            
        }

above/below logic gate

        string direction;
        vector tardir=llVecNorm(target-mypos);

        if(tardir.z <0)
        {
            direction="below";
        }
        else if(tardir.z>0)
        {
            direction="above";
        }
