Hmm, following Commander McLane's fine example, I haven't downloaded the WIP yet, but I do have a question: what happens if you're in a nova system?

By the way, and because I've downloaded the OXP now:

• When the player ship is docked, it still exists. Therefore your code would not remove the missile. I think it would get parked 1000 meters away from the station.

Here is the answer to Commander McLanes question.

if(!player.ship.docked)
{
    this.ship.commsMessage("your message", player.ship);
}

While testing the OXP I found that if player ship is in a position where the planet is between the sunskimmermissile, it can not reach the player at all.

It'll probably hit the planet. I can imagine two reasons for that:

1) the gotoWaypointAI isn't designed for circumnavigating planet-sized obstacles. It only corrects the course a little bit in order to avoid small obstacles, but can't manage to avoid the planet; or

2) the missile is too fast. When the obstacle is detected, a waypoint is set and gotoWaypointAI kicks in, it is already too late for course corrections, because the missile has already smashed into the planet.

You could try to check which is correct by logging the missile's AI messages.

This will probably happen with every condition that puts the missile in a gotoWaypointAI. The reason is that the missile it to fast for how the code was written. You now have:

Code: Select all

 "WAYPOINT_SET" = ("setAITo: gotoWaypointAI.plist");
"DESIRED_RANGE_ACHIEVED" = ("commsMessageByUnpiloted: Ready for pick-up.", becomeUncontrolledThargon);
UPDATE = ("sendScriptMessage: locatePlayer", "pauseAI: 5.0");

When it returns from a gotoWaypointAI, the range is still 50 meter, triggering the DESIRED_RANGE_ACHIEVED quite soon. Normally the range is reset in UPDATE, but for fast ships UPDATE might come to late. Better add the line

Code: Select all

"RESTARTED" = ("setDesiredRangeTo: 1000.0");

That line makes sure that any previous range from the gotoWaypointAI is reset at the moment your AI takes over control again.

Sorry Thargoid, I could not get the question right, what do you mean?

Missiles have a maximum range (set in their AI) - after they exceed that they explode. I was just wondering if that was happening in your case here?
