Hi there !

I'm working on a fleet of drones in Gazebo, and I'm using ROS to control it (beginner). I have a topic that allows to publish a new target to one of my drones, but not to all. I add this target to a list, but it is not visible by other drones. How can I make this subscribed variable accessible to my entire fleet?

Here are my callback function, the published topic and my target tracking function, which only applies to the intelaerobugwright4 drone in this case.

def target_tracking(self):
    if len(self.target_list)>0:
        last = len(self.target_list) - 1
        target = self.target_list[last]
        self.target_pxyz = np.array([
            target.position.x,
            target.position.y,
            target.position.z])
        self.target_psi = quaternion2psi([
            target.orientation.x,
            target.orientation.y,
            target.orientation.z,
            target.orientation.w])
        TargetDiff = self.target_pxyz - self.state_pxyz
        NormTargetDiff = np.linalg.norm(TargetDiff)
        TargetDiff /= NormTargetDiff
        TargetDiff *= SigmoidLike(NormTargetDiff, self.R_trg, self.d_trg)
        return (TargetDiff*self.freq)
    else:
        return np.zeros(3)
