I have a path object and would like to use it to give a way for many actors.

Any actor is placed in a diferent position along this path but allways near or on the line. It means that the actor placed near by the first waypoint will work normaly with the acctual function. But the next actor can be near to the nth. waypoint.

How can I do to make the others start following the nth. waypoint?

Thanks

You could use the normal scan_path to find the path that the actor is nearest to, then cycle through all the points on the path to check which one is closest. Just start the actor from this point.

eg.

code:

---

var numPoints;
var nearestPoint;
var minDist;
...
// find the path - you could also use numPoints = ent_path("yourPathName");
temp.pan = 360; // scan the full sphere
temp.tilt = 180;
temp.z = 1000;   // max distance the entity can be from the first waypoint
numPoints = scan_path(my.x,temp);


// find the closest point on the path
nearestPoint = 0;
ent_waypoint(vecTo,nearestPoint);
minDist = vec_dist(my.x,vecTo);
temp = 1;
while(temp < numPoints)
{
   // retrieve the next point
   ent_waypoint(vecTo,temp);

   // compare to the previous nearest point
   if(vec_dist(my.x,vecTo) < minDist)
   {
      // found a new nearest point
      nearestPoint = temp;
      minDist = vec_dist(my.x,vecTo);
   }

    temp += 1;
}

// nearestPoint now holds the index of the waypoint closest to the actor
