random question about torpedo splitting

[Flowrellik]

Is there a way for a torpedo to fire out and when after impact on shield or hull will separate into smaller torpedoes?

[Tethys]

Actually, the Akira that I acquired from someone who has since disappeared, Zoran Koren, has torpedoes which split into several smaller ones, however they split before any shield/hull impacts. I will see if I can find the scripts he used.

[Morgan]

FTech allows for "spread" torpedoes - essentially you fire a torpedo and it spreads into multiple ones right off the bat.  Blackrook's common weapons pack makes use of this.

You could also setup spread properties in the ship hardpoint so that it will fire all the tubes at once in a spread pattern.

[Flowrellik]

Hmm I guess that can do for now. I thought about actually having the hellbore torpedo for BC to fire out as a slightly powerful torpedo as a whole with a function that when split will become fast homing micro hellbores that spread wide outward then locked on the enemy ship with precision, allowing the torpedoes to hit the ship like it was a DBZ Style Hellzone Grenade.

You could also setup spread properties in the ship hardpoint so that it will fire all the tubes at once in a spread pattern.

The biggest problem with BC's built-in torpedo spread function is the incredibly long delay between torpedo launch and the time before the torps start to seek the target. By the time they begin to track (about 2 seconds or so) they are sometimes completely past the target, making the spread ability only useful if you fire from very long range.

I really wish there was some way to reduce that seek delay, but I have a feeling it's hard-coded into the game.

[Tethys]

Unfortunately, all I can find is the pyc file. No py file was ever included when he sent me the files. I'm sorry.

It can be done, though. I'm not sure who even made the pyc but its named PhotonTorpedoMultiple.py/c

[KrrKs]

What morgan said!

There is a 'TimedTorpedoes' file in FTB, including a 'MIRVSingleTargetTorpedo' class and a 'MIRVMultiTargetTorpedo' that are used e.g., in

some bcsTNG stuff, not sure which exactly.

An example torpedo has these lines added at the end:

Code: [Select]

try:
import FoundationTech
import ftb.Tech.TimedTorpedoes

oFire = ftb.Tech.TimedTorpedoes.MIRVSingleTargetTorpedo(
'Spread2', {
'spreadNumber': 2,
'spreadDensity': 7.5,
'warheadModule': 'Custom.BCSTNG.CWP.Scripts.blackelmtype6',
'shellLive': 0,
})
FoundationTech.dOnFires[__name__] = oFire
except:
pass

By the time they begin to track (about 2 seconds or so) they are sometimes completely past the target, making the spread ability only useful if you fire from very long range.

This is true.  When I do use BC's built in spread function I tend to only do so at a distance of about 40km - this gives the torpedoes enough time to start tracking without missing and passing the target.  Any closer and you'll want to stick with single launches.

[Flowrellik]

I guess it really can be a pain in the butt huh? Shame I don't have those MIRV torpedoes. Mind sending them over Krrks along with a tutorial?

[Tethys]

You can decompile pyc now, I did decompile the PhotonTorpedoMultiple.pyc, here ya go

scripts/Tactical/Projectiles

They are part of FTech, together with a Readme that includes explanations and how-to s for all included techs.

Ftech can be found on gamefront or the nexus.

Ok so I'm gonna need some help. I tried combining scripts together for a single torpedo.
I'm trying to recreate a custom version of SFC's "Plasma Shotgun".
For some stupid reason it's not working, and I have no idea what I'm doing here because I cannot seem to fix this.

Are there any exceptions displayed in the console?

Just from the looks your torp seems fine (that TargetHit function rubs me the wrong way for some reason, but idk).

I don't have access to my pc for most of the next 2 weeks, so i can't really test it.

[Flowrellik]

Idk what I did wrong here. Every time I tried on this code it does not show up in game, the torpedo that's loaded just does not show up

[Flowrellik]

So yeah I have absolutely no idea why this isn't working. 

[Morgan]

I never played SFC so I'm not familiar with the plasma shotgun.

Did you add in the FTech properties manually?  Or did you use BCUT?

[Flowrellik]

Mine was manually. Afaik I have no idea how to apply plasma tech and Split torpedo script tech via BCUT. My BCUT is version 1.8.1.0

Try this instead:

Something after the ftech import was preventing your torpedo from compiling properly, not sure what exactly.

[Morgan]

Mine was manually. Afaik I have no idea how to apply plasma tech and Split torpedo script tech via BCUT. My BCUT is version 1.8.1.0

It's easy in BCUT.  Just go to the BC Tools button and select "Torpedo Tech Creator" from the menu.  You'll be able to select the torpedo you want to add tech to and which tech you want to add from the menus there.

[Flowrellik]

That's the thing Morgan. That split torpedo tech is not there on mine :V
