how to mod space haven to remove systempoints costs

wanna make that battleship with 20 turrets, 10 hull stability, and 6 shields? here's an easy how-to to mod space haven to remove 'systemPoints' costs.

editing space haven:

[update: aug 2022, version alpha 15 0.15.2]

how to edit systempoints to build up your 20 gun warship:

*always make backups for any files you edit*

1) go into your space haven root directory and find 'spacehaven.jar', open with your favorite decompression program. winrar is recommended as it preserves .jar metadata.

2) navigate to '\library' directory and find the file 'haven'

3) extract 'haven' and open with your favorite text editor

4) search and replace 6 instances of

systemPoints="2"

into

systemPoints="0"

, there are only 6 instances in the entire file

5) search and replace 10 instances of

systemPoints="1"

into

systemPoints="0"

, there are only 10 instances in the entire file

6) save and exit 'haven' and add it back (overwrite) into 'spacehaven.jar' in the correct directory ('\library') with your compression program.

7) you're done, go and build that space battle ship!

You can increase your Crew in this File. Just search : "maxcrew"
You need to look some lines up and check if its a tutorial or something else.

@SiteSeer, I figured it out with the help of someone on the discord and subsequently made a guide to cover that specific aspect of the process. Thank you for your reply nonetheless

@mroddlyfox use winrar to open the .jar, extract the file, and overwrite and repackage after you edit the haven file. i personally haven't played the game in months. maybe i'll build a copy of my space haven ship in starfield.

[Mr. Oddly Fox]

Yeah. I can't seem to get the files back into a jar file once unpacked and edited. I have no intention of learning Java to accomplish this. Perhaps since you seem to have created a guide on this subject, you could enlighten your audience.

[Mr. Oddly Fox]

another variable I located in my code searching was canvaspoints (core points). editing the system points makes that irrelevant, but it could come in handy.

6) save and exit 'haven' and add it back (overwrite) into 'spacehaven.jar' in the correct directory ('\library') with your compression program. please explain once im done editing the file where do i drop the file in ? is it - spacehaven.jar/library ?

Sadly this doesn't seem to work if you use the bigger ship "hack", even putting all of the systempoints to 0 you can't claim any ships along the way which means that missions that involve claiming asteroids for mining outposts and such are impossible to complete.

So I'm guessing that the ship size system points is hardcoded, so this method really only works for guns and other stuff.

@superraiders Open the spacehave.jar file with 7zip (Winrar works too). Extract the haven file from the library directory. Open it using Notepad++ [notepad-plus-plus.org]. That seems to handle the file better. Yes I still see "systempoint="2" in a ton of instances. Haven't fully tinkered with the game yet but if it doesn't work I'll return and make an update. Hopefully I'll be able to find a workaround.

[Superraiders]

Is it just me or did the new update make this no longer viable? Trying to use notepad to open the spacehaven.jar file now just shows a bunch of random characters.
