Permanent GalDrive OXP

Post by Wildeblood »

Sensible GalDrive OXP ver. 0.9
Date: November 20th, 2011

http://www.boxcn.net/s/0721l5ga2anm0qyu5o2n

This OXP removes the traditional, 5000cr, one-shot, "Galactic Hyperdrive" from the game, and re-implements it as a 40000cr, permanently-installed "Long-Range Hyperdrive". This changes Oolite's gameplay somewhat - it will be deemed an obvious improvement by some players and heresy by others. To use, place the Sensible GalDrive OXP into your "AddOns" folder.

After purchasing the Long-Range Hyperdrive from any planet of technical level 11 or higher, use the prime-able equipment (N-key) menu to arm or disarm the hyperdrive. Whenever the hyperdrive is armed, you can make a long-range jump to a new galactic sector in the familiar way (g-key by default).
There you go. That's as far as I've got with this idea.

It's a very good idea. The normal wutchspace drive needs fuel, so why can't this one? How about five light years to go to a new galaxy?

If you consider it 'sensible' for it to consume fuel (i.e. if you're diverging from the canon 'all galactic drive requirements are self-contained') it could well stand to reason that the permanent gal drive might need more fuel than a standard 7ly hop...

Why not a full 7ly tank plus an external 3ly fuel pod? :twisted:



Still, - and I know, I am repeating myself - this idea would be a lot more sensible if you didn't make changes to standard equipment that actually 'break' one of the standard Oolite missions.
As it is now, this oxp makes it extremely unlikely for the nova mission to ever happen, and - in case it acutally happens - it would make an already difficult to solve problem into one that's basically impossible to solve without prior knowledge.

Suggestion: why not simply make it only available to be bought after the nova mission has taken place, explanation being that the tragedy of a planet having been destroyed and the difficulties faced by those helping to evacuate inspired its creation?

Good suggestion/compromise - except it won't satisfy/pacify the "now now now" element...

Suddenly more sensible already! :D

Maybe a random number of jumps afterward you get news on docking that due to safety concerns blah, blah... mind you, the new gal drive would still make things more difficult for a pilot in a similar situation...

As long as the core galdrive still exists alongside with the permanent one, it can always be rationalized as a company using the event to launch and advertise (read spin-doctor) a new must-have safety gadget - possibly interacting with YAH and the newscasts...Astral phenomena are known to produce this kind of overreaction in RL.
You know those who, having been mugged and stabbed, fired, dog run over, house burned down, wife eloped with best friend, daughters becoming prostitutes and their countries invaded - still say that "all is well"?
I'm obviously not one of them.

I would have thought the oobvious thing to do was only make it available in Sector 8.

Why not design a little mission which allows you to win one when you get to G8? The native missions end after G5 and this would be a nice little extra.

Umm, Nova starts with a fuel leak, and the new drive thingie needs a full tank to work.

So where is the issue, other than people using an extra fuel tank, which breaks the mission anyway...? For me the new one doesn't break anything (indeed it unbreaks something, as the current one can be used to escape the nova system).

Righto, I just did the mission in question. The result was an almost 1 megabyte log file full of this junk:-

By the look of it, there are multiple bugs here.

The stack overflow is because of 'exitingTraderAI' uses a "setAITo:" when failing to jump. That raises the stack, but the AI it jumps to has no 'exitAI' command by which it could return. I'll change that to a "switchAITo:" command.

That still would lead to hopping between two AIs because it can't find a station as arriving trader and has not enough fuel as exiting-trader.

But the main bug seems to be the addition of traders in a system that has no station at all :P

EDIT to above.

I think we introduced this bug by adding the 'hyperspace_motor' motor to the sidewinder. Normally the nova mission uses the special command 'sendAllShipsAway' That command gives all ships a full fueltank and sets them in an exitingTraderAI. In the past this was enough to send all ships away, but now the ones without hyperspace motor are trapped in the system. Although, that being trapped in the system was sort of the intention of the hyperspace_motor :lol:

Doing some tests by excluding the ships with hyperspace motor in the 'sendAllShipsAway()' code helps a bit. Escorts are now unaffected and follow their mother through their wormhole.

During experimenting, I found also some buggy oxps that use a role "none". That role is a NONO in use. All kind of code used this role to exclude ships from being added.
e.g.
some code adds a 'none' station to a system. (that used to work, but does not longer)
the sendAllShipsAway(0 code uses this role to prevent copies from being added at the witchpoint. But when there exists ships with a 'none' role, the whole entry point gets covered with such ships. One that I found had the name "weapons Array' but there were dozens of those ships near the entry point :(

Clearly a bug in XeptatisSword :twisted:
