[1.8.x-1.12.x] Module Manager 4.2.3 (July 03th 2023) - Fireworks season

sarbian · May 26, 2015

Not with the current version. I am considering adding a step that delete value that use a specific naming pattern after all the value and subnode of a node are processed. Something like deleting all var whose name start with an underscore.

Same thing with formula. No way to do 1 line complex math currently. I could do yet an other syntax to handle it but I would need a lib/code to do the parsing.

Hi everyone,
I'm trying to do this task with a module manager patch :
For all tanks with LFO :
- Add the firespitter "FSfuelSwitch" module with the given 3 options
- LFO (unchanged)
- LF Only (twice the amount of LF from LFO mode)
- Ox Only (twice the amount of Ox from LFO mode)
- Remove the old resources as they are replaced by firespitter
I was kinda pleased with the following patch (it's not balanced yet and makes all tanks available at start so I could check them fast in game) : http://paste.ubuntu.com/11359289/
In the patched version of the game configuration (I'm looking at the ConfigCache file), I can find my variables in the module instance (you may check this result for the Kerbodyne S3-14400 Tank : http://paste.ubuntu.com/11359383/ )
Is there a way to prevent this "pollution" ?
Is there a way to use formulas in a patch file ?
This patch is not an original idea as it is just a try to make the "Stock Fuel Switch" mod apply to all possible tanks.

While not being able to help with your pollution, just another thing.

I'm currently doing something similar. As LF and O have the same density, LF Only (or Ox Only) doesn't equalize "twice the amount", but rather "both combined".

If a tank has 90 LF / 110 Ox (or whatever, you now the usual ratio ), it doesn't have 180 LF or 220 Ox, but rather exactly 200 of each in "solo-mode".

Best guess is because there is no just ( Cost ) it's ( unitCost = 0.8 )
EDIT-
@RESOURCE_DEFINITION[LiquidFuel]
{
    @unitCost = 10
}

This does't work either. The resource costs in the game are still stock.

What did you name you patch ? It works for me.

EDIT- I named my patch Z_Price.cfg

EDIT- Will run test again to make sure.

I named it DFResourceCosts and put it inside /GameData/Rock/

Change the name the name you have and folder is running before Squad.

EDIT- Would think you can just rename your patch file.

EDIT- Or add :AFTER

@RESOURCE_DEFINITION[LiquidFuel]:AFTER[squad]
{
@unitCost = 10
}

I could guess the volume of a tank from its current then run through all ressources and add all of them with calculations based on density.

I made my own rules for my own setup, it let me have one tank full of LF and an other full of Ox and still have the same ratio.

If you want such complicated calculations you may be interested into Modular Fuel Tanks mod. It does the job for you with all resources.

Not with the current version. I am considering adding a step that delete value that use a specific naming pattern after all the value and subnode of a node are processed. Something like deleting all var whose name start with an underscore.

No harm in this, I'm taking all good pratices I can to help not messing up my patches or later have a mod that conflicts with mine.

By the way, is there a way to test a patch just like the test cases I could find on github ? ( I'm an other guy that know nothing of C# )

I know the patch task is fast but having to load the entire Unity engine is a pain even with 3/4 of stock parts removed.

I can later provide my tests if you want some non-regression testing.

You can press ATL F11 on the spacecenter screen and use that menu to reload all the config + patch. Works fine to test patch and you can see the result in the cache.

MatterBeam · May 26, 2015

Will test this.

Did not work. Will try :FINAL.

Has anyone had any success modifying EVE CloudLayers.cfg with mm?

I'm trying to change the cloud altitude and speeds.

sarbian · May 27, 2015

Tricky it is. All his resources one must uses.



@CLOUD_LAYER_PACK
{
    @CLOUD_LAYER:HAS[@DEFAULTS:HAS[#body[Laythe]]]
    {
        @DEFAULTS
        {
          @altitude  = 6500
        }
    }
}

I assume that there is only DEFAULTS node per CLOUD_LAYER node. If not you ll have to replace the


@DEFAULTS
{
  @altitude  = 6500
}

with


@DEFAULTS,0
{
  @altitude  = 6500
}

@DEFAULTS,1
{
  @altitude  = 7500
}

...

Paul Kingtiger · May 27, 2015

Tricky it is. All his resources one must uses....

You're a superstar!

Am I right in saying i can use | to effect multiple bodies like below?

@CLOUD_LAYER_PACK
{
    @CLOUD_LAYER:HAS[@DEFAULTS:HAS[#body[Laythe|Duna|Kerbin]]]
    {
        @DEFAULTS
        {
          @altitude  = 6500
        }
    }
}

UPDATE

Think I've answered my own question and the answer is no.

I'll resort to directly editing the Resources file and providing the player with the original alongside it.

There's nothing about RESOURCE_REQUEST, and I don't know why I should be using # here, but I think


@PART_DEFINITION
[*]:HAS[#part[cupola]
{
@part = cupola
}
@RESOURCE_REQUEST
[*]:HAS[#name[Xenon_Gas]]
{
@Name = XenonGas}
}

should work?

NathanKell · May 29, 2015

Krakenfour: Nodes are nodes. There's nothing special about RESOURCE_REQUEST or RESOURCE_DEFINITION or PART or FOObarcurvestuff. If there's a { after it, it's a node; if there's a = after it, it's a value.

So I want to replace a value in one module, but only if two AND conditions are met in a different module. The example code below will make MM give an error on the load screen, but it actually works exactly how I want and I see the changes I made in the game, as intended.

MMTEST is the main config file, @MMTEST contains the edits, and MMEXPECTED gives the actual results of the code.

The error happens because one of the @dislikes edits in @MMTEST will give an empty value. However, MM seems to simply ignore the empty value and just keep the default value or the most recent edit, which is what I want. But I get an error message on the loading screen.

Does anyone know how to get rid of the error (since it gives me the desired result)? Or can show me the correct way to write my code?

A variable lookup that hits an empty result set is reported as an error because your "apply this edit only if there's something in the result set" use case is literally the only pattern where you would want the behavior.

I happen to recall that you can OR multiple groups of criteria together in one HAS block, so if you want to access "the first of Dog or Bird that has fourLegs = true", you can write that as one line:

@dislikes = #$/ANIMAL:HAS[#id[Dog]fourLegs[True]|#id[bird]fourLegs[True]],0/id$

Didn't work:( It works if only the first AND or both ANDs are true (either results in the /id for the first AND), but I get an error if only the second AND is true and the value defaults, which is not desired behavior.

Is there any way to write

MODULE:HAS[(#A AND #True) OR (#B AND #True) OR (#C AND #True) OR ...],0?

Edit:

Ã¢â‚¬â€¹The following doesn't seem to work either. I get the same pattern of errors as above.

@dislikes = #$/ANIMAL:HAS[#id[Dog]|#id[bird]fourLegs[True]],0/id$

I was trying for

MODULE:HAS[(#A OR #B OR #C OR ...) AND #True],0

AFAIK the HAS block does not support or at all, only and.

Looking at the code, it looks like | for OR is allowed in HAS blocks at the top level (i.e. @PART:HAS[]) but not in sub-nodes or variable lookups.

Ah, that's the distinction. Good catch, thanks for the info!
