Shipchange issues

RPC · Thu Feb 10, 2011 2:12 am

I was working with plyChangeShip and I was wondering how to 'save' the state of a ship. Instead of keeping one ship as a wingman [I don't like losing my ships], I am trying to create my ship with code so that only one ship is in Trans space at any given time. That way, when I change ships, I have no chance of losing my other ship. Any suggestions on how to implement this?

You could dump all the data onto the new ship with enumerations & (objSetData ...) but it would be rather painful to do it that way. I'm sure there's a better way.

Oh, you could set the position of the ship to some insane number, like, 1000000,1000000, far outside the system, and then set it to wait. However, this I think can cause the "gatekeeper" bug where for some reason the far-out object can become targeted by the player.

You can also use objSuspend to suspend the ship. That effectively removes it from the universe. You can then objResume it at a later time. Do note however, that if you move to another system you can not access any suspended objects in the previous systems.

Another option is to do like wolfy suggests and save the data manually and reapply it when you switch ships. I think you would just have to save items and their installed state.

ObjSuspend sounds interesting. However, it's only inside the .tdb and not on Xelerus, so it it a global? How does it work specifically (I can't fathom what it does or how to use it just from two uses in the gladiator arena xml) and I don't know if there are any limitations.

You'd have to save any important overlays as well.

Suspending the old ship is your best bet.

(objSuspend obj) -> effectively makes the ship disappear. You can still access it with code, but no other game objects will target it IIRC.

(objResume obj) -> undo for suspension

Use a background station to watch when you gate out of a system and jump your suspended ships with you. I believe overlays are also saved when a ship is suspended.

they should be. >.> That would be a bug otherwise, no?

Where exactly does ObjSuspend store the data?

Where exactly does ObjSuspend store the data?

It keeps it as an object in the system, but "suspends" it so that it does not interact with any other object (or update itself).

It remains a real object, though, so you can use any objXYZ call on it. It is part of the system, though, so you cannot refer to it from a different system.

Note also that there are probably a bunch of edge-conditions that I haven't tried. For example, what happens if a wingman is suspended and the player leaves the system? Does the suspended ship follow? I don't know--you'll have to try it out.

Hmm, objSuspend is kind of interesting. I'm testing it on the playership right now, and noticed a couple things. Enemies still try to attack you, even though their shots cant hit (spawn a hostile station with GOD to see this.)

Actually, this is an oddity, SHIPS attack you but STATIONS don't. I think I'll ticket that ...

Ships don't stop attacking NPC ships that are suspended, but new ships don't start attacking them.

It also dosen't cancel the velocity of the playership, the view keeps drifiting and the ship appears where it would be when you resume it.

In general, especially if the targetting issues are resolved and jumping works, it'll be great for internal docking of ships / carrier ships. (If those tickets I planted about locked docking are fixed, they'll need to account for the parent ship jumping; remembering suspended ships for this would make it easy. Dock with something, suspend the docked ship, have it auto-jump with parent ship...)

On that note, can we have ObjSuspend ( or a similar function )return data so we can spawn it regardless of which system we're in?

That way we can do ObjResume without worrying about system changes.

Are you wanting objResume to move the suspended object to the new system, or do you just want something like the objByID functions where you can get a globalized pointer to the thing that does nothing in the wrong system?

RPC · Tue Jun 05, 2012 11:12 pm

I want to ObjSuspend my ship in one system and ObjResume my ship in another system.

And you want it to then be in the new system, not merely be active in the prior system when you go back there again, right?
