I still don't see the problem. Is your request not the same what you are already doing for years in the Hammerhead?

Doing it in one function gives:

Code: Select all

globalPosition = this.ship.position.add(localPosition.rotateBy(this.ship.orientation));
localPosition being the position in ship coordinates and globalPosition the position in system coordinates.

Not quite - it's actually the inverse (the Hammerhead is converting local to global, whereas I needed to go the other way). But it was indeed that coding which gave me the inspiration check about how to invert a quaternion. A quick hunt around the net gave me a solution, which is what Cim has now kindly integrated into trunk as noted as it's quite a useful thing to have available.

The code above isn't quite right I think (not tried it) as you need to rotate by the inverse of the player ship orientation, not by just the orientation itself.

Something I mentioned in passing on the Progress thread but perhaps got lost in the general discussion-
Can we have the ability to attach exhausts to sub-entities please? At the moment they have to be attached to the 'main' ship, which means if the sub-entity is removed or destroyed the exhaust prevails (which is/looks silly!). This feature would be of great help to me in my current project, and would also make shoot-off-able engine sub-ents a realistic and workable possibility. :D

Or as an alternative (as I think exhausts are a special kind of sub-ent themselves, and so you'd end up with the sub-ent of a sub-ent question) could the current special sub-entities (exhausts and flashers) be exposed with r/w to scripting? Either within the usual subEntities array, or perhaps in an array (or two) of their own.

That way we could do the tweaks like Smivs suggests, but also for flashers have them more independently controlled and controllable.

Which normally works, but because of the way exhaust display is calculated might be more troublesome. Making the sub-ent types scriptable seems better to me, at least in so far as allowing remove/restore, but probably not for 1.77/8.

Ah, OK. Something to look forward to then. :)

I realize we're in a freeze for 1.77, but after - How hard would it be to make the camera position readable? We can set camera position (player.ship.setCustomView), so why can't we read it? (Or can we, and I just didn't find it?)

This is a big request :D.

A functionality for an oxp to add dynamic text layers to the screen. I've been abusing message_gui for this, which not a very clean solution.

event handler that runs after a game is loaded

Post by GGShinobi »

I'm currently working with spara on an update for his [wiki]Updating TSC[/wiki].oxp, and I ran into a little problem there:

We want the equipment to be automatically awarded to the players ship if the ship has an [wiki]Advanced Space Compass[/wiki] (ASC) installed.

I've looked at the event list that can be found in the wiki, and I already use playerBoughtEquipment and playerBoughtNewShip to add the equipment in the respective cases. But I have not found a nice way to add it if the player's ship already had an ASC installed before he installed the oxp.

My current workaround will be to use another event, for example shipWillLaunchFromStation for the check if an ASC is installed and add the equipment if so. But this is a little bit of overkill, since it would be sufficient to check it only after a game is loaded. So, something like a "playerHasLoadedGame" (similar to the playerWillSaveGame-event) would be nice in the future :)

Can you test

Code: Select all

player.ship.equipmentStatus("EQ_???")

That would be the simplest way. Do a test on game start-up (see below) and if that fails (ie they don't have the ASC) then do a test on equipment purchase as already noted below.

Alternatively this.playerHasLoadedGame is otherwise known as [url=http://wiki.alioth.net/index.php/Oolite_JavaScript_Reference:_world_script_event_handlers#startUp]this.startUp[/url].

:shock: :!: That is exactly what I've been looking for! I didn't get that from the description in the wiki - there it sounded to me like that event is run (only once) after the game has been started. And I already wondered why no one else has been missing such an event. :lol:

I made an edit to the wiki to point out that the event is called also when a game is loaded. Question :?:: Does this mean that everytime I load a new game, all OXPs are reloaded? If so, the entry in the wiki should be edited, e.g. by changing the sentence to "This also means that it is also called after the player has loaded a game."

Anyway, thanks again! :D

Yes, OXPs are reloaded when you load a new game.

Would it be possible to make galaxy and system writable from JS (i.e. - change the current system) during startup?
