Blender game engine track to a property I there any way to duplicate the action of the Edit object &gt; Track to Actuator; so that it can track to a game property and not a object? It would be used to track multiple objects without having to list them all as separate track to actuators in the logic bricks.

blend file demo
You can only track one object at any given time, so you'll need to define a set of priorities by which a single target can be selected from a group of valid candidates (objects with the relevant property).

For example, if you wanted to track the closest object with the relevant property, you could do it with this function:

# track.py

def target_prop(cont):
    self = cont.owner
    objects = self.scene.objects

    tracked = [o for o in objects if self["target_prop"] in o]
    tracked.sort(key=lambda o: self.getDistanceTo(o))

    target, *_ = tracked

    act_track, *_ = cont.actuators
    act_track.object = target

    for act in cont.actuators:
        cont.activate(act)


Example: track_to_prop.blend

As you can see, you can specify the target property via a property on the tracking object (target_prop in this case). Also, you can set the always sensor to "true level triggering" (aka: "pulse mode"), to constantly re-evaluate the closest target, if that's required.
