What is your maximum speed

Okti · Post by **Okti** » Tue Apr 05, 2011 6:05 pm

I would like to find out maximum speed player ships speed, used by the players.

I may need to edit the post later, because I used the entries used in shipdata.plist.

The speed of Dark.

No matter how fast light is, it always gets there first...

That's another good one

By the way I know max speed for a NPC is set in shipdata.plist, but is there a way to set it by JS

The speed of silence...you can't even hear it coming.

Nope. Most of the hard ship specs are read-only in JS. The documentation tells you so, also for maxSpeed. It tells you also if something is read-write.

I knew the reply, but it may be a good thing to set up an npc's speed according to player ships speed.

I know that is possible to set in AI, but is there a way to set percentage of the speed, according to criteria in JS?

Script-wise you can use desiredSpeed, which works the same way as the AI equivalent.

But of course just because you set it in script doesn't mean that the ship's AI won't then change it again, depending on the AI code. And also the desiredSpeed is of course capped at the maxSpeed.

Thanks Thargoid,

I will try that.

Thargoid already answered that one. Speed is something else than maximum speed. Just because a car can make 180 km/h doesn't mean that it's going at this maximum speed all the time. Sometimes it goes slower, sometimes it even stops.

The same is true for Oolite. ship.speed is something else than ship.maxSpeed. There is also ship.cruiseSpeed, which is always 80% of ship.maxSpeed. All of these are read-only in JS. If you want to set a ship's speed you have to use ship.desiredSpeed, with the caveat mentioned by Thargoid. NPCs are meant to be flown by AIs, not by scripts. In Oolite 2 these two will perhaps be more integrated than they are now. And even now you could try to give a ship nullAI and fly it only by script commands. I am not sure, however, which advantages that would have. The state machine system has proven itself kind of useful for NPC-flying.

You could also try to experiment with ship.velocity.

If NPC ships have injectors, they can move up to 7x normal max speed until they run out of fuel.
...But you may need to tell them to do so.

No, it isn’t (which is why it’s exposed). cruiseSpeed can be lowered to 99 % of the maximum speed of a ship’s slowest escort in order to keep formations together.

Ah yes, I forgot that.

So it would be more correct to say that cruiseSpeed is usually 80% of maxSpeed, especially if the ship in question doesn't have escorts.
