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

ev0 · August 12, 2015

Hide Empty Tech Tree Nodes v1.2.0 (December 5, 2020)

Who this mod is for:

This mod is for people who use large modded tech trees, such as the awesome Community Tech Tree mod by Nertea, but don't have enough part mods installed to fill up all of the new tech tree nodes and hate the empty tech nodes. Additional features give you even more control over the tech tree.

What it does:

Main feature:

Adds option to hide any empty tech tree nodes, which automatically connects the resultant "hanging" tech tree lines to unhidden nodes in a logical sense.

Additional features:

Adds option to hide unresearched nodes, similar to Fog of Tech. Disabled by default.
Adds option to change all node unlock requirements to "Any" or "All".
Adds option to manually set which nodes are hidden (when enabled, this uses "hideEmpty" from RDNode modules. These can be edited with ModuleManager). *new
Adds option to transfer science points from hidden nodes to their children/descendants. *new
Adds option to remove empty space caused my missing rows/columns of empty nodes.
Adds options to change the zoom settings, so you can fit your large, modded tech tree onto your screen all at once. Default minimum zoom is changed from 60% to 35%.

Feel free to further customize your tech tree using using Module Manager to suit your play style, by adding nodes, changing default node positions, etc. (with the appropriate edits!). This mod will take care of everything else.

Examples (click either picture to enter album):

Notes on mod behavior:

Spoiler

In order to fix some "anomalous" :wink: in-game issues with hidden tech nodes when outside of the R&D center, this mod has changed from a "visual" mod to an "active" mod. It now automatically creates a new tech tree file from your MM tech tree file, and tells the game to use this new file. It creates this new file each time you start a new game or resume an old saved game, so please add new part mods at any time without any worry! However because of the new mod behavior, there may be new bugs. Please let me know if you find any!

Some Recommended Tech Trees:

The Community Tech Tree or any number or awesome tech trees, such as

Historical Progression Tech Tree

*Engineering Tech Tree (<- see notes below)

UnKerballed Start

*Notes on ETT support:

Spoiler

This mod supports tech trees in the ETT format, but does not support the Yonge's Tech Tree plugin. This simply means that the tree selection process at the beginning of a new game will do nothing. Instead, this mod reads the ETT changes done to the ModuleManager tech tree, and will change the TechRequired field for Parts from that file. The good news is that you can now use ModuleManager config files on the ETT!

The bad news is that modders who add their own nodes probably haven't accounted for the ETT because they never needed to yet, so there might be duplicate nodes (they need to add a NEEDS[!ETT] to their config file). If there are duplicate nodes in your MM tech tree, a message will display on screen and the debug log will give you a list of duplicate nodes so you can inform the modder.

I have used this since you put it up in the CTT thread, thanks for sharing!

Beetlecat · August 12, 2015

My biggest distraction when using the CTT is now addressed! Thank you.

Great mod! CTT would be harder to use without it.

Gottcha. I'll be able to take a look at it in a couple days, I'm away from home right now.

ev0 · September 20, 2015

Ok, I think I fixed the problem. You can download the updated plugin from the Dropbox link again. Let me know if you see any other problems and I'll try to fix them before 1.1 comes.

Errol · September 21, 2015

Have rep

Jovus · October 11, 2015

Is there any chance of this getting indexed by CKAN? Having to search 10 or 20 pages into the forums is less good (and mind-boggling; how does everyone using CTT not use this?)

JeffreyCor · October 12, 2015

Having this on Kerbalstuff would be great! And thank you for making it, you saved CCT for me

ev0 · October 13, 2015

Whelp, I was going to wait until 1.1, then 1.05, but I went ahead and put it on Kerbalstuff. I think it's set up correctly for CKAN too, but it seems to be taking a few days. A different mod that was put on Kerbalstuff a couple days before mine is still waiting to be put into CKAN/Netkan's repository too, as seen from CKAN's github page.

pacbard · October 13, 2015

The best way to contact the CKAN admins is through the IRC chat on the #ckan channel or on their forum thread.

Thanks. On the #ckan channel, they said that the mods are added manually to CKAN after they are automatically submitted by Kerbalstuff, so it's just a matter of waiting until someone is able to take care of it.

Well, it looks like your pull request is being held back because of the proposed change to the netkan file. I fixed it up for you. This is the new pull request.

Great! Thanks!

Looks like your KerbalStuff link in the OP is wrong; should be this one: https://kerbalstuff.com/mod/1206/Hide%20Empty%20Tech%20Nodes

Fixed! I had an extra slash at the end of the link.

Jovus · October 14, 2015

Yaaay!

Fraz86 · December 5, 2015

Has anyone tested this in 1.05?

ev0 · December 11, 2015

Whoops, I thought the CKAN guys said they were going to make 1.0.4 mods available for 1.0.5. I'm waiting for 1.1 before I play again, so I didn't see that I had to update until now.

It still works. I also increased the minimum zoom so you an see your larger tech tree more easily. You can change it back to the default zoom value in the "overrides" file. Let me know if 0.35 is too low, because for me, if I tried to go lower then the KSC would become visible and clicking on the tech tree wouldn't work anymore. You can try for yourself. I'll probably add hard-coded max/min values next time.

Hi, is your mod supposed to work with Engineering Tech Tree too? I tried, but it didn't hide empty nodes. Would it be a lot of work to make your mod work for that tree too, ev0?

It kind of works with the ETT. But you'll need to change a line in "overrides.cfg" first (in the HideEmptyTechLines folder, in the GamaData folder).

Change

@TechTree:NEEDS[CommunityTechTree]:FINAL

to

@TechTree:NEEDS[CommunityTechTree|ETT]:FINAL

I think. .... I should get rid of that NEEDS part in the future.

But you'll most likely have some tech lines intersecting some tech nodes (hopefully you won't!). I want to see if I can make it work for the ETT too, but only after KSP v1.1. The ETT is much tighter than the CTT, so I might need to find a different method to make sure that nothing intersects.

Check this post for reference.

I just tried it like you suggested - it seems to work, there are no overlaps as far as I can see. This is great. Thank you very much.

Does anything need to be changed with the CTT under 1.1?

Note sure. I don't have the Steam version so I can't check yet. I'll update the mod if it's broken when 1.1 hits.
