[1.12.x] Hide Empty Tech Tree Nodes (for modded tech trees) v1.3.2

Nobody6 · May 23, 2016

Hello,
I just found and added this mod to my RP-0 install (because not having to research empty nodes sounds like a good idea), however, it seems it is not compatible with "Fog of Tech", as all nodes are now exposed again.

Hello,

Really? I just tried an install with only my plugin, Fog of Tech, and of course Module Manager. It seems to work for me.

If it's still not working, the plugin might be getting an error somewhere else. Can you turn on "debug" in GameData/HideEmptyTechTreeNodes/overrides.cfg, and then send me the output_log.txt file in the KSP(_x64)_Data folder, along with a list of your mods?

Thanks. I've gotten a bit busy recently, hopefully I'll be able to take a look at it soon enough. :wink: Got a week long work trip coming up next week though...

Lithium-7 · June 13, 2016

Ey, you might still be out on your trip, but I'll bring this to your attention:

1F1F820D33CCC819A8AFCC15FA126043150D751A

The Orbital Assembly node, which I think is from one of the NearFuture mods, and the Ultra High Energy Physics node from the USI Alcubierre Drive mod depend on hidden Community Tech Tree nodes with no parts in them, and their dependencies haven't been re-sorted.

Unlocking the Orbital Assembly parts will not be very important for what I want to do, and the warp drive is more of a victory trophy anyway.

I'm not sure if your mod includes a way to fix this, but I do know it doesn't CAUSE the issue, since this was already present when I didn't have a complete install of Community Tech Tree before.

Also, I think this is a problem with CTT or NearFuture, but the Advanced Nuclear Propulsion and Very Heavy Rocketry nodes overlap. They're still usable, though.

Sorry, I got back from my work trip late last week, but now I've got a Master's thesis to work on due next month :wink:

It wasn't too clear from your post, but you have my Hide Empty Tech Tree Nodes plugin installed, yes? And the problem is that there are the two "hanging" nodes without parents?

If you're using this plugin, it's very possible that it got held up somewhere and didn't finish connecting the nodes to each other. This mod works as follows:

Hide empty nodes. This is done just using Module Manager in a .cfg file.
Connect unhidden nodes to other unhidden nodes, via a .dll plugin.

So part one finished, but the .dll didn't run correctly (it has bad error checking :blush: ).

But if you're just using the CTT and a few other mods like NearFuture, then it should have worked just fine...

BUT, if you're not using this plugin, how did you hide the empty nodes to begin with?

Probably with the CTT or a different mod. My plugin doesn't change the location of any nodes (yet). How does the CTT look when it's the only mod you have installed? There should be no overlapping nodes (however a couple of the lines connecting the nodes do overlap).

Yeah, it's installed.

I'll check how CTT looks when installed alone later.

ev0 · June 23, 2016

Current version seems to work with KSP v1.1.3. Did a quick SpaceDock/CKAN update to reflect that.

SmashBrown · June 26, 2016

Thanks for your effort on this, Cures the OCD

SilverlightPony · August 2, 2016

Has anyone tried this on 1.1.2? That's where my main game is, and all the empty nodes are driving me nuts.

[EDIT] Trying it now. Seems to be working. One broken link, but downstream nodes are still connected by another link, so no harm done. See pic.

The X in 1.1.X means it should work in any version of KSP 1.1. So it shouldn't have any broken links... I'll check the code within the next couple days when I have a bit of time. :wink:

Side note: This mod isn't listed in CKAN anymore if you're using KSP 1.1.2. I didn't know. That's a shame. SpaceDock gave me the option to tell it that the current version of this mod works for 1.1.3, without having to upload it again. I guess when I did that, it overwrote the KSP version compatibility. I wonder if that's a SpaceDock meta data problem, or a CKAN problem not taking advantage of the meta data. I'll find out and see if I can get it back on CKAN for KSP 1.1.2, too.

Based on my understanding of CKAN, it's a metadata thing. Plenty of other mods have a range of compatible KSP versions. That said, it's entirely possible (from what little I know about the ins & outs of SpaceDock) that setting a compatibility range in the metadata is only possible when uploading a new version, and not when changing it on an existing file.

I just kind of assumed that SpaceDock/CKAN would keep track of min/max versions automatically when SpaceDock asks if my plugin is still compatible with the new KSP version and I say "yes".

I asked about it on the CKAN forum page. Hopefully there's an automated fix. If not, I'll do a manual fix to get it back on CKAN for 1.1.2 when I fix your broken line problem.

Oddly, installing this mod seems to have made my game much more laggy and crashy (in the VAB at least; haven't done anything else since installing it). :/

Thx for this mod! From your activity here in the board I hope/assume a 1.2 version is a WIP?

Yep, it's still a WIP. Taking a little longer to fix than I expected, but I should be finished soon-ish. :wink:

ev0 · October 20, 2016

Okay, I think I got it working. I cleaned up the code a bit too so it'll be easier to update next time. Get it at SpaceDock or wait for CKAN's automated upload!

Let me know if there are any weird looking tech lines. I'll test it again when the new CTT update comes out. I'm also up for making the mod work for the ETT, so if you see any wrong tech lines there, take a picture and let me know! :wink:

Hmm good question. This is the first time I'm hearing about a stock upgrade system (I haven't started playing yet). Where can I learn about it?

To put it as simply as possible, this mod just removes and adds Parent nodes where needed in the tech tree. Might this affect the upgrade system?

Edit: Just in case, I should mention it does the removing/adding each time you enter the RnD center.

@ev0 I did a quick test with the latest version and unfortunately it appears to ignore stock upgrade placeholders in determining if a technode is shown.

I'll take a look this weekend. Are some upgrade placeholders "part-less" nodes, temporarily or otherwise? I haven't seen how they work yet.

FreeThinker · October 20, 2016

Well you can install http://kerbalspaceprogram.com/files/PartOverhauls.zip

or

Which has already included many tech upgrade placeholders (I don't know their official name)

I do not understand how you mod work, but I can imagine its very easy to scan for the upgrade definitions and use it to make tech nodes visible

here is a small example:

PARTUPGRADE
{
	name = ThermalEnergyConverterUpgradeA
	partIcon = SmallFNGeneratorMk1
	techRequired = specializedElectrics
	entryCost = 0
	cost = 0 // for display only; all parts implementing this will need a PartStatsUpgradeModule with cost = this.
	
	title = THermal Energy Generator Upgrade
	//basicInfo = Whatever\nblah
	manufacturer = Jebediah Kerman's Junkyard and Spacecraft Parts Co
	description = When reseached will improve maximum efficiency thermal electric engine
}

So, just search for PARTUPGRADE and add the techRequired to your list of nodes that need to remain visible

Aha, that's the info I needed. Thanks! But instead of keeping the "techRequired" node visible, if it has no parts in it then I'll probably switch it to a different node that does have parts.
