Understand 'Sudden Death'

[hiran]

While I am fighting targoids I am sniping them from a distance of roghly 20 km using the Vimana Beam.
My ship is not damaged, not even shields are impacted.

Then all of a sudden there is a whomp and I see the ship from outside with a glowing hull. The text showing up is there way too short for me to read, then I respawn inside the station. This happened a second time today so I am wondering what might have happened.

Since you guys were not there and have even less a clue, I grabbed a few lines from Latest.log:

Code: Select all

01:02:17.948 [LogEvents]: ship lost EQ_TARGETSELECTOR_MODECHANGER
01:02:17.950 [LogEvents]: docked to Coriolis Station 22894

Does that contain the reason? The ship was lost because of the target selector? Or did the target selector loose the target because my whole ship was destroyed?

Something is up in Ooniverse, and it may come for you too!

Seeing your ship from outside and the being auto docked sounds like the sequence that plays out when you use your escape capsule? the ship glowing also sounds like it's critically hot, have you got any expansions that auto eject you when the ship explodes and one that plays with the ship temperature? It's usually just getting too close to the star for too long or fuel injecting through a planet atmosphere that heats the ship enough for it to explode in the base game i think?

Yes, I have the Auto-Eject equipment installed.
And yes, I agree a red glowing hull would indicate temperature.
But while fighting the thargoids I am facing space beyond the witchspace beacon, looking from the planet side. It's usually far off the sun so I do not think that was the reason.

Somehow I could imagine I hit into something, or something hit into me. A collision with a rocket (although there was no such warning and I do have Auto-ECM as well). I know life is not fair and maybe you do not get warned on sudden death, let alone an explanation for the afterlife.
Still I want to know what/why lead to this situation so I can prevent it next time.

Well, actually it is not the afterlife. I just need to know why my auto-eject system ejected me.

[Switeck]

Your ship badly overheating may trigger Auto-Eject...why it's badly overheating may be due to another OXP/OXZ.

Maybe try adding extra logging in Auto-Eject as to the cause of why it ejected you?

Now you made me think. Often I shoot the Vimana Beam often enough the system shuts down due to overheating.
But since it shuts down I never thought whether that could have additional impact.

Yes, adding logging or a message showing up in the escape pod will definitely help.
So for a first time I need to look into some OXZ and try to modify something. Auto-Eject is an OXZ authored by Commander McLane.

OoliteStarter v0.1.18-cheese.1 will more easily allow to detect the download URL for a given OXZ. This way I identified the OXP to come from http://wiki.alioth.net/img_auth.php/4/4 ... ct_1.2.oxz.

It contains a nice readme with this content:

Foole's Systems™ proudly presents the Auto Eject Module. This small upgrade to your escape pod constantly monitors your remaining energy. Should the energy level fall under the adjustable critical threshold it automatically launches your escape capsule, and you begin your journey to the nearest station or planet.

and further

The Foole's Systems™ Auto Eject Module is fully adjustable in-flight via the primeable equipment control. Once you have selected the item (default SHIFT-N) you can switch it on or off via pressing N. And you can adjust the threshold at which the module is activated via pressing B. Three options are at your disposal: the MEDIUM setting, which is also the default, sets the module to activate when one third of your last energy bank is left. In HIGH setting the module is activated already when a little more than half of your last energy bank is left. The LOW setting allows your energy to sink to less than one sixth of the last bank before you're ejected. The LOW setting carries the risk that the mechanism triggers too late, which may result in pilot existence failure. At HIGH setting you should be safe from this, but at the opposite risk of triggering too early and losing your cargo. Foole's Systems™ accepts no liability for the possible consequences of your preferred setting.

So I might want to check that setting and my energy level. Plus maybe some modification of the code to print a message when taking a decision.
It will take the steps
- unpack OXZ and place as OXP in AddOns folder
- modify scripts until I have desired messages
- modify manifest.plist (also remove Index.plist and requires.plist)
- add information url https://wiki.alioth.net/index.php/Auto_eject_OXP
- add new author
- increase version number
- update readme.rtf
- pack it back into OXZ format
- improve Wiki page https://wiki.alioth.net/index.php/Auto_eject_OXP (we have an OXZ)

But then the question is: How do I upload/publish the OXP so it superseeds the existing expansion?

[hiran]

Umm, I found this in the world-script. Basically it means there are console messages already.
Are these just shown in the game or also logged in Latest.log? Maybe that is exactly the message I missed as it disappeared too fast...

Code: Select all

this.shipTakingDamage = function()
{
	if( Math.min(player.ship.forwardShield, player.ship.aftShield) + player.ship.energy < this.energyThreshold
		&& this.autoEjectOn == 1)
	{
		if(player.ship.equipmentStatus("EQ_ESCAPE_POD") === "EQUIPMENT_OK" && player.ship.equipmentStatus("EQ_AUTO_EJECT") === "EQUIPMENT_OK")
		{
			player.consoleMessage("WARNING! Energy critically low! Auto Eject module activated.", 6);
			player.ship.abandonShip();
		}
		if(player.ship.equipmentStatus("EQ_ESCAPE_POD") === "EQUIPMENT_DAMAGED")
		{
			player.consoleMessage("WARNING! Energy critically low! Escape capsule off-line!", 6);
		}
		if(player.ship.equipmentStatus("EQ_AUTO_EJECT") === "EQUIPMENT_DAMAGED")
		{
			player.consoleMessage("WARNING! Energy critically low! Auto Eject module off-line!", 6);
		}
	}
}

The one OXP which does play with ship temperature is Phkb's Ship Configuration (see all the Heat Sink gubbins below - and he even included the controls in his Vimana-X HUD).

Cabin Temperature and Heat Sinks

A number of different activities and events will now impact on cabin temperature. These are:

Use of your hyperdrive
Laser temperature
Use of fuel injectors
Use of cloaking device
Laser hits on an unshielded hull
Running your ship with an overloaded electrical bus

Each of these things on their own probably won't cook your ship, but if you combine two or three of them at the same time you can expect to see your cabin temperature reach dangerous levels quickly.

Therefore care must be taken to (a) select appropriate lasers, engines and thrusters for the roles you want to perform, and (b) be careful how you use your lasers, fuel injectors and the cloaking device to avoid overheating your cabin and potentially causing catastrophic damage to your ship.

Note: Entering hyperspace with high levels of heat increases your chance of having a misjump.

To help with controlling cabin temperature, heat sinks can be purchased at all tech level 2 systems and above. You can purchase several heat sinks, but each one takes up 1t of cargo space, and adds 2t of weight.

To deploy a heat sink, first prime the "Heat Sink Control" item by using the Shift-N key sequence, then press "N" to activate it. Up to approximately 25% of your cabin temperature can be jettisoned in this way, dependant on the size of your ship. For larger ships this value will be closer to 10%.

You can also set the heat sink control to automatically deploy heat sinks whenever your cabin temperature reaches 75% of maximum. To do this, prime the "Heat Sink Control" and then select "B" to change the mode from "Manual control" to "Automatic control".

Heat sinks can be damaged, and cannot be used when in a damaged state.

Heat Shields also help with cabin heat. Higher levels of heat shield will slow the rate at which cabin temperature builds up.

	}
}

ConsoleMessages are only shown on screen, not copied to the log.
The log message about EQ_TARGETSELECTOR_MODECHANGER is because that piece of equipment is automatically removed from your ship when you dock, which is the event that is taking place at the time you describe, just after auto-ejecting.

Ship Repurchase is another OXP that might auto-eject you, pretty much for the same reasons, when your energy is critically low.

Good catch, but neither of these two expansions is part of my set.

Similar issue or different?

I wanted to travel to another star system, which took several jumps. In one of the intermediate star systems I activated the torus to get away from other traffic, then made up my mind and triggered the hyperspace jump. All of a sudden the jump is not happening and I have a damapged police scanner. What did my ship hit?

Here is a snippet from Latest.log, and this time my Nexus oxp is part of it as it simply logs all calls to it's world script without actually doing anything about it.

This has twice happened to me in the past week. An occasional malfunction. It is when my maintenance level is lowish (c.90% or less).

[hiran]

Maybe I am getting closer to the root cause.
This time, while I was fighting a thargoid, something flashed up eventually - looked like a thargoid robot extremely close to my ship. Since it flashed up twice only I did not see it right and should have taken evasive action. Instead I focused on the thargoid. Then I was out of my ship.

That Thargoid Cruiser took a severe dislike to you.

What on earth did you say to it?

You are obviously not using the Broadcast Comms - Digebiti Variations OXP, which utilises the appropriate honorifics and terms of address.

You have only yourself to blame....

The dislike must have been mutual. Neither of us communicated, and they started the fire first...
But if you think that damage was harsh - I have had it worse:

taking 3312615424 scrape damage from Rock Hermit 13569 0+384 shield and -3312607488 energy left

Wow, Oolite does distinguish taking energy damage and scrape damage!

[hiran]

I think I am getting annoyed a bit now.
Again, while shooting Thargoids in a perfectly functional ship I suddenly find myself out in space.
Again I do not understand what actually happened.

I am taking minimal damage from a Thargoig Battleship and it's robot.
And while shooting the Battleship several times, all of a sudden the auto eject module activates.

What is taking so much of energy in the fraction of a second?
