Per drone, yeah.
One other thing you want to do that's subtle in its effects:
drone.getAIFlags().setFlag(AIFlags.DRONE_MOTHERSHIP, 20000f, mothership);
If this isn't done, things will work, but enemy AI will be more distracted by the drones than it should be.
ship.getAIFlags().setFlag(ShipwideAIFlags.AIFlags.DRONE_MOTHERSHIP, 20000.0f, (java.lang.Object)this.ship);If you're implementing your own, then there would be no DroneLauncherShipSystemAPI and no states - whatever you code up has to handle states etc. You would, I think, set the AI to what you need when manually spawning the drone.
I'd suggest using type:"STAT_MOD" since that doesn't do anything and lets your script have full control. The script can be specified via "statsScript".
Hmm - I don't think so, no - sorry! I mean, you might try to write a custom version of the drone launcher system from the ground up - basically launching drones/maintaining its own state as needed - but the existing drone launcher system isn't that flexible.Yikes - well, I might as well go all out. Can I have some info on how the existing system launches drones onto the map? Is it as simple as spawning in the combat entity with a reversed velocity? Do I need to extend BaseShipSystemScript? How does it interface with the systems csv and/or json configuration?
. This is working with ~80ish lines of code without any direct manipulation of velocity or location, only shipcommands, showing it is possible 
For a drone, I'd suggest directly manipulating the velocity and or/location. You're going to have a tough time getting nice-looking movement otherwise.
. Thanks for the help, I'll start looking into that stuff.
Thanks for the help earlier, I'm currently fine-tuning the drone movement, and I was wondering how the param of Ship.giveCommand(..., param, ...) works. I've only been setting the param as null, but the API mentions param - Generally a Vector2f with a "mouse" location. See ShipCommand.java for details., but as far as I can see ShipCommand.java doesn't have any comment on a mouse location. Does this mean that I can choose to make the e.g. accelerate command act in a certain direction instead of cardinally? The code below shows what I have. This is quite innacurate as the drones only move diagonally or straight, which causes them to overshoot, correct, then fly around amusingly. Thanks!
"param" is for commands that need a mouse location, such as firing a weapon (missiles uses this for target-picking), using a ship system, or raising shields.
//MOVE TO TARGET LOCATION
float angleFromDroneToTargetLocation = VectorUtils.getAngleStrict(drone.getLocation(), movementTargetLocationOnShip);
float angleRelativeToDrone = MathUtils.getShortestRotation(drone.getFacing(), angleFromDroneToTargetLocation);
float distanceToTargetLocation = MathUtils.getDistance(drone.getLocation(), movementTargetLocationOnShip);
//do large movement if over distance threshold
if (distanceToTargetLocation >= roamRange) {
//accelerate forwards or backwards
if (90f > angleRelativeToDrone && angleRelativeToDrone > -90f) { //between 90 and -90 is an acute angle therefore in front
drone.giveCommand(ShipCommand.ACCELERATE, null, 0);
drone.giveCommand(ShipCommand.ACCELERATE, null, 0);
drone.giveCommand(ShipCommand.ACCELERATE, null, 0);
} else { //falls between 90 to 180 or -90 to -180, which should be obtuse and thus relatively behind
drone.giveCommand(ShipCommand.ACCELERATE_BACKWARDS, null, 0);
}
//strafe left or right
if (180f > angleRelativeToDrone && angleRelativeToDrone > 0f) { //between 0 and 180 (i.e. left)
drone.giveCommand(ShipCommand.STRAFE_LEFT, null, 0);
} else { //between 0 and -180 (i.e. right)
drone.giveCommand(ShipCommand.STRAFE_RIGHT, null, 0);
}
} else {
snapTo(ship, 0.1f, drone, movementTargetLocationOnShip);
}
//some fine tuning and deceleration
if (distanceToTargetLocation <= roamRange * 2f) {
drone.giveCommand(ShipCommand.DECELERATE, null, 0);
if (tracker.intervalElapsed()) {
//decelerate if close to target location or attempt to reverse thrust
if (distanceToTargetLocation <= roamRange) {
drone.giveCommand(ShipCommand.DECELERATE, null, 0);

It's okay, I'm not Anglo myself, so I'm well-equipped to interpret your writing.
That aside... I was just hit with a realization that should've come to me the moment I considered this issue.
Wouldn't the immense depths of a typical water world just crush anything at the bottom into a solid, immovable orb? Could tectonic activity even happen when the lithosphere is being subjected to obscene amounts of pressure from every direction?
I'm not an expert, but that seems unlikely. Even our own little Mariana Trench(11km) is terrifying with how easily it can crush things, so imagine what a world of only water that's 100s of miles deep can do. Even if there were some plate tectonics, I feel like the pressure would be strong enough to keep their effects localized and they would never reach the surface.
What do you think?
