I can answer that one - yes!Smivs wrote:Can we now (1.79 on) save elsewhere other than at main stations...
Station has to be spawned in the populator, has to be spawned to the same place and has to be enabled per station by using deterministic flag in the populator. In the core you can save at the hermits' in addition to the main stations. Of the oxp stations I have enabled saving at Rescue Stations and Space Bars.Smivs wrote:Just a quick question (to save me hours of trawling through the BB) regarding game saves. Can we now (1.79 on) save elsewhere other than at main stations, and if so, is there a way to prevent a player saving at a specified non-main station?
Yes. You need to set the deterministic flag in populator to true. By default, it's false.Smivs wrote:Thanks. So if I understand correctly saving is not possible at an OXP station unless you make it so, is that correct?

here for details. Core's oolite-populator.js is worth to check too.<Groans> I haven't even started to look at that yet! Ho-hum...spara wrote:you need to rethink the whole spawning business. No more spawning on launch and stuff, you need to use the new populator.
I hope once you've got your head round it you'll see the opportunities for simplification of the current way of doing things in the long-term, but yes, it's a bit different to what was there before, and a little bit more code to do the initial set up.Smivs wrote:This is more complicated than I thought!
system.addShips in shipWillExitWitchspace and/or other suitable event handlers. Oolite has no way to tell from this that you are adding objects that you intend to add the next time the system is visited / reloaded, and rates the chances of their reappearance as low. Therefore, you can't save at them.systemWillPopulate event handler. This still uses system.addShips eventually, but it has three advantages:shipWillExitWitchspace ... oh, but then it won't appear if the player starts in the system, so shipWillLaunchFromStation as well ... but what happens if they launch twice, etc?". I've seen enough bugs end up in OXPs that way: pretty much every OXP of mine that added ships in shipWillExitWitchspace had to have a bugfix release for "except for in interstellar space" (and then most of them also separately "except in nova systems").Code: Select all
this.systemWillPopulate = function()
{
if (this.isASystemWithAPizza()) {
system.setPopulator("smivs_giantspacepizza",
{
// a position closer to the sun than the planet is to the sun, but not too close
location: "INNER_SYSTEM_OFFPLANE",
// fix the position to be the same one every time, rather than random
locationSeed: 621863,
// these will always appear the same so long as this OXP is installed
deterministic: true,
// and this is what adds them. It gets given a 'pos' parameter, which is the result of
// Oolite translating location "INNER_SYSTEM_OFFPLANE: 621863" into real coordinates
callback: function(pos) {
system.addShips("smivs-visitor-centre",1,pos,0); // add the visitor centre to the coordinates specified
system.addShips("smivs-giant-pizza",1,pos.add([15E3,0,0]),0); // add the pizza nearby
}
});
}
