[PLUGIN,0.15.X,0.16] Start-Stop Engines V 0.1 (Alpha)

[jgjiscool]

Finally it will be possible! You will be able to shut down engines when you don\'t need them, and start them back up when you do... WITHOUT JUST STOPPING THE THRUST!!! Big Red Button Pressers presents to you:

Start-Stop Plugin

It\'s still a work in progress, but here it is so far:

This version hopefully works for 0.16. I haven\'t tested it so let me know if it works or not.

http://dl.dropbox.com/u/59317800/BRBP%20LFE%20Control%20Part%20Class%20Only.zip

This version creates a new part class that stops the override of the main engines. Use this if you use another plugin to control your engines or you don\'t want this ridiculous function on the other engines.

http://dl.dropbox.com/u/59317800/BRBP%20LFE%20Complete%20Override.zip

This version creates a complete override of the existing LiquidEngine part class giving Start-Stop functions to any engine. It does not appear to work with other plugins that take exclusive control of the engines.

KNOWN ISSUES:

* Does not work with tri-couplers (FIXED) *

* Can not spawn multiple windows *

Good Luck Kerbalnauts!!!

P.s. DO NOT TRY TO OPEN MULTIPLE WINDOWS!!! CLOSE THEM BEFORE YOU OPEN ANOTHER ONE!!!

[Tiberion]

Not per engine?

Needs to be per engine.

[jgjiscool]

Yes. Per engine. Each engine has it\'s own window that will appear only in flight if you click on it.

[Tiberion]

Cool - if you click on it in the stage list?

I approve. Go go go

[jgjiscool]

Mmmmm. Haven\'t tested that, but it still may work. I\'ll figure it out anyway. BTW, the module actually DOES work, the engine code just isn\'t in it yet.

[Iskierka]

If it only works with specially made engines, it isn\'t going to catch on much, with how restricting that will be ...

[jgjiscool]

<.<

>.>

I\'m a programmer...

I have ways...

[swamismurf]

This is how we do in flight tweakables. Click on the part to open adjust settings window, adjust settings, commit.

If one were to extend this and combine it with the ASAS or MechJeb, would modifying the KIP parameters from frame to frame force the ASAS/Jeb to update its behavior?

[jgjiscool]

This would work, BUT not as an extension of the class. At least that I know of. I have tried to commit my code to the LiquidEngine module, but it doesn\'t appear to work. Not that I checked after I resolved the internal naming conflict...

[Pair of skis]

Hmm...

[jgjiscool]

GUESS WHAT!!!??? If I use the same class definition as an existing part module, MY PLUGIN WILL OVERRIDE THE BUILT IN MODULE!!! Brilliant! Now to get it working just like the standard engine!

Set the maxThrust of your engines to 0 when you disable them if you will override the default code... I\'ll need to poke at the engines to find the available thrust at any moment, if some engine is disabled but reporting thrust, it will end up with the rocket not getting into a proper orbit with the ascent module, or crashing to the surface with the descent one.

Also remember that if anyone else decides to replace the stock LiquidEngine, things will go BAD.

A better option would be for you to make an extra part that scans the vessel for LiquidEngines and control them.

[jgjiscool]

Oh... This basically works just like the standard LiquidEngine component except it adds a new GUI. Would it really do *that* much damage? They do work at the moment by the way. But only one on a rocket, because the GUI screws up for the others, and you can\'t put them under a tricoupler, strut, etc. But I\'m working on it.

[Cepheus]

I like where this is going. +1 to you.

[jgjiscool]

Don\'t add anything yet. I don\'t have a lot of success yet...

[jgjiscool]

--- UPLOADING NOW ---

Briefing will be in the top post

[Causeless]

Ok, really? You are kidding me... A triple post.

Editing bumps. Edit older posts.

[NovaSilisko]

Hate to break it to you but there\'s lots of triple posts by other people (not going to name names for fear of reprisal...)

[jgjiscool]

*Embarrased* Woops. I can remove the 'Coming soon' post... Sorry.

[Reflector]

Since .16, the LiquidEngine module has been considered replaced by the LiquidFuelEngine module, any chance of updating this plugin jgjiscool? I\'ve found it useful on some ship designs which use mixed engine types for variable thrust vs fuel consumption capability.

[jgjiscool]

Well I wasn\'t planning on it, but...

It may or may not work. You\'ll need to let me know. Being 16 has made me lazy...

[Reflector]

Appears to break the new engine system and makes it consume fuel like the original mode when I tested it.

[fowlplaychiken]

Isnt that a good thing, since the new system is broken? haha
