[REL] Ship damage from fires

[TheDarkWraith]

I played SH4 for maybe 10 mintues then shelved it for good as I just couldn't get into it. That being said, I have no idea what mods have done to the game (nor do I really care as I won't be playing it ever due to SH5) but if there are mods that have improved the damage model of the ships then, in theory due to how I made this work, ships should also flood due to fires. It would be quite possible to see a vessel sink due to flooding from the fires. Can anyone confirm this?

I know little about modding, but I can tell you what is in the documentation for RFB. The Real Fleet Boat has a damadge model that is based on the flooding of compartments. It often takes quite a while for ships to sink, but not always (there are 'critical hits' sometimes). Shelling a ship, often causes fires, but does not sink them, unless there are a significant number of hits near the waterline. This can seem odd, as it is possible to have raging fires aboard a ship, which means very little. The fires are essentially eye-candy here. I hope this answers part of your question.

Edit- There is also the matter of ships not counting when they 'sink' in shallow water.

Raging fires will cause damage to the vessel. That damage will more than likely cause flooding to occur in the damaged comparments. Now this damage to the compartments will increase over time (due to the fires) and thus the rate of flooding will increase also (theoretically)

I just wrote a offhand description of the RFB damadge model.
I don't know if the damadge zones in the superstructure would be affected by what happens in the hull, or vice-versa. From what others have said, shell damadge accomplishes little unless the hits are near the waterline, but the fires appear to be located in the superstructure.

To use an example: I broke into a convoy at night and was shelling a tanker. My hits were toward the stern, and it was soon a mass of flames. I thought it was finished, or at the very least, crippled. I started on other targets, only to see five min. later the fires out and the tanker sailing away. The fires seem to be for visuals only. This is in RFB. IDK about TMO or stock.

If fires are displayed (rendered) then the vessel will suffer damage from them. I don't care whose mod you're using (or stock for that matter)

OK, good to know.

Thanks for the nice improvement, I'll check it out.

Flooding from fire could occur depending on the damage done by the fires. Mainly, though, keeping the fire from the fuel, or coal depending on what the uses would be the main reason.

But heat and flame, could do things like undermine the structure by warping or buckling things that cause a chain reaction of things leading to eventual flooding from seams splitting and what not on the hull.

I'll have to give this a try once I get back in port.

Don't have to be in port to install. Can be installed at any time

[Hylander_1314]

Oh, cool! Just used to having to be back in port to add stuff.

Thanks, this mod really adds a lot to the game.

Sorry to have to report no joy there.

Started 2 fires on a Med. Modern Composite Freighter with the single 20mm - doing as little damage to the ship as possible, then i just followed the freighter for 24hrs (game time). Still afloat and burning, with no reduction in speed at that time (clean install of SH4 - 1.5 with no other mods).

Repeated. this time the freighter slowed from 5 kts to 1kt in the first 3 hours, but did not sink after 24.

Third test: started a fire but this time with 4 shells from the deck gun. Followed the burning ship for 1 hr., then started a second and third fire with the single 20mm. Ship sank by flooding while I was starting the third fire. I've never sunk a freighter with a 20mm before.

The fires do not seem to be enough to sink a medium sized freighter by them selves, but do seem to amplify other damage done to the target. Very nice!

As the mod was made with SH5 damage model in mind the SH4 damage model and ship available HPs will most likely be completely different. Thus it's quite possible that the SH4 version needs to be tweaked for SH4. I don't play SH4 (only SH5) so someone would need to do this

Well beyond my skills I'm afraid, but even based on the SH5's damage model - ship fires will now contribute to sinking - which is a big improvement.

Thanks again

i know with sh4 there were some issues with some fires (smaller ones) not having any sounds attached to them and vickers03 had done a small tweak to fix this for my GFO mod some time ago, do you think this sound fix may have anything to do with or interfere with the way your mod works?

or maybe vickers03 could better answer this

I hook the fire events so unless someone changes the fire's IDs or changes the effect that's played for fire in the Zones.cfg file there's nothing to worry about
