This is a must whenever i get into a SE mood

currently playing survival alone so it's hard for me to test, but does this work on connected grids? eg if I make a drone that connects to other grids via a connector, will it attempt to hack the attached grid?

Getting issues running this block on a multiplayer server:

log please. they are helpful for finding problems.

yea this is broken it crashes upon being fully welded and functional

What an amazing mod !

after the first placement (sorry for delayed reply)

Does this happen after placing a second one, or is that the first one in the world?

Hi, as soon as we complete welding the hacking computer (in a coop game with 1 friend) the game instantly crashes. to follow this message is the relevant section of the crash log that is generated, hope it helps with fixing (though i guess it could also be partly due to the recent update?:

Thanks for the update!

Thank you!

Restarted a few mins ago my world and was confused where was the damn H.C pressing 5 where i have it normaly made me look here as i hadnt realized you made an update good to see ppl still working in there mods i loved the old look at some spacey vibe to it but the new Models? They..are..beautiful it fits it so much more i love your mod and it is such a big help when taking over a grid i wanna keep or salvage thank you for your work

that may

Hey, I might be able to help you with a crash log. First, background story. I tried to take over a bigger NPC ship but after hours of fighting against the defence system until the ship ran out of energy and ammonition and more hours trying to hack everything to take over the grid, I lost my patience. So I checked the workshop for a mod supporting me and found yours!

So, I added it to the dedicated server, joined the game, put like 15 hacking computer on the NCP ship (let me lie, I already hacked 200 blocks, 50 are still somewhere hidden). I saw, that the computers changed between yellow and green, saw failed hacking attemps. All looked like it is working. So I went back to my ship appx. 900 m away hidden in an asteroid, did some work there, wanted to fly now with my ship towards the half-taken over NPC ship. Then the server crashed. A restart is possible, but 10 seconds after I have joined, it crashes again.

Do you have a log for the crash? Can't fix what I don't know about.

Crashed server after a few were placed on an NPC to hack it, though we have around 80 mods, removing this mod solved any crash. Loved this idea and the models though, will be missed.

I love this mod but only ever used it in single player and I wana test in on my server. Glad to hear it does not work on subgrids? I really would not want it to work through NPC trade connectors.

That being said you can add those hacking chips to the station yourself! It's easy to write such a mod- just look at your components.sbc file and observe these entries on any component:
<MinimumOfferAmount>250</MinimumOfferAmount>
<MaximumOfferAmount>1000</MaximumOfferAmount>
<MinimumOrderAmount>125</MinimumOrderAmount>
<MaximumOrderAmount>1000</MaximumOrderAmount>

Once your hacking component has those entries under it it can show up in stations as buy or sell respectively. It's cost is auto-calculated based off what it takes to make it, hopefully the original mod maker already filled all those blanks out (for the hacking components build requirements) because that's another search and I gotta run right now.

That would be great!

yes, I can add that option, I'll have to refresh how the economy stuff works

Hello! Is it possible to make the chip for the Hacking Computer be purchased at trading stations?

possibly with some code changes, but one of the mechanics was that you could defend blocks by having them off.

is their a way to make it hack remote controls/blocks that are turned off?

yes, and this was the main reason for the mod, so you didn't have to grind your way through grids

I am finding out that not allmods play nice :O but I like this as it makes taking over a base easier then finding every single block and grinding it down then rebuilding it just to claim the thing.

is there a way to make it hack through connectors?

sometimes that's from a bad download, and sometimes it's keens updates that cause that.

just wanted to add this here. When I initially added the mod (that I haven't used in a while) to a previous save, I got a message saying that the save was corrupted. I removed the mod and tried reloading the save. after a longer load time then usual, it loaded and played just fine. I unsubscribed and resubscribed to the mod before attempting to reintroduce it to the same save. Seemed to load and play with no issues.

Where does the firewall flash? It seems to have no visual indication of cyberattacks

The firewall description states that it forces all hacking computers to attack it first.

Testing between two identical grids with 1 firewall, and 4 hacking computers would be ideal. You would want to limit the firewalls to just one per grid. I can't remember if the hacking computers attack firewalls first or not, you want enough to be able to overcome the firewall block.

Hey guys! I'm running this on my server and I'm trying to limit it. I don't want end-game players to have hundreds of hacking computers and firewalls on a grid and then simply land on another's grid and own it almost instantly. What would be a good ration to limit the blocks at?

Thanks again for the response and info. i must have been sleeping or some such after trying it locally not sure what i was doing wrong it works jsut fine on server running long around 80 other various mods. Thanks again for the great Mods!

k thanks for the response, I am running the server but i do have a lot of other mods running. I will try to play with the mod order as well as verify i can get it running locally first.

If it's not flashing orange/red/teal, then it's not working properly on that server, depends on server, they might have scripts disabled or a mod conflict

Do you have to attach it to a specific type of block, trying to take over a pirate base have attached the hacking computer in several different areas but it never seems to active or do anything. on a server, lots of other mods. no errors just doesn't seem to do anything.

hacking torpedoes it is!

In a way like your ship is the USB loaded with virus lol

That was requested feature, along with landing gear hacking

So we've figured out on my server that we can build a hacking computer on our ship and dock on a grid via connector and it's hacking the other grid. I assume this is not intended
