Reading .cfg fields

[peachoftree]

I'm trying to write a wimple plugin that lets me reset goo containers and science bays at the cost of a resource, but I'm not sure how to access the fields in a module. For example if i have a module

PART{
foo = 7
MODULE
{
    bar = 8
}
}

I am not sure how to access the field bar from my code.

You do that using KSPField, as such:

[KSPField]
public float foo;

A KSPField is then usable as a standard variable in the rest of your code.

You can of course bypass this to avoid having values intended for displaying info only being changed by players.

More info in this thread, Example #1 should give you all the info you need: http://forum.kerbalspaceprogram.com/threads/92643-Official-PartModule-Documentation

sorry I misstated my question. what I meant to ask was if you had a .cfg file set up like this

foobar = 10
MODULE
{
    name = my_module
    foo = 9
}
MODULE
{
    name = some_other_module
    bar = 9
}

I know how to access foobar and foo from my code but am not sure how to get bar.

When does your code run?

Since all those fields get loaded by the module(s) in question, you probably will want to get the some_other_module PartModule on the part you're on and get the value from there, rather than going back to the original confignode it was loaded from.

I don't know why i'm so terrible at stating my questions:P. What I really want to know is when loading config fields with [KSPFields] does the fields location matter? for example if i have a config like this:

PART
{
    cost = 4
    MODULE 
    {
       name = my_module
       foo = 5
    }
    MODULE
    {
         name = other_module
         bar = 9
    }
}

will:

[KSPField]
float cost;

[KSPField]
float foo;

[KSPField]
float bar;

work.

or do I have to do something different to access cost and bar?

my plugin loads in the flight scene and what do you mean by "get the some_other_part_module". Sorry if the questions i'm asking are obvious but i'm very new to c# and ksp modding so any help is greatly appreciated

If your class is a PartModule[-derived class], and you thus have a MODULE{} node in a part.cfg that refers to your PartModule, then the only KSPFields you will see will be the ones in *your* MODULE{} node.

ok. so is there no way to access the aforementioned bar and cost feilds? the mod im working on adds a mechanism to reset science bays and goo canisters with a resource and eva. Similar to dang it's method of repairing parts with spares, except i'm reseting science experiments with cleanout kits. I need to acess the Inoperable feild in ModuleScienceExperiment but have not found a way to do that.

All KSPFields are public and have methods for altering them, so you just need to access the Part that your PartModule is attached to or some other PartModule attached to the same Part.

/* From within your part module */

//Set the cost field to 5000
part.Fields.SetValue("cost", 5000);

//Set the other modules bar value to 10
PartModule pm = part.FindModulesImplementing<other_module>();
other_module.Fields.SetValue("bar", 10);

I've never actually tried to do this before, but it seems like it should work. There are also GetValue and ReadValue methods, and overloads to specify the type the field is using.

Accessing the other PartModule assumes that you actually have access to its Type, if it's from some other mod then you'll have to use some other method to assign the PartModule before you can get to its fields.

[peachoftree]

wouldn't I have to use

pm.Feilds.setValue("bar", 10);

to access other_module's field?

[NathanKell]

KSPFields are usually just members, and as DMagic said are public. If you already are referencing whatever defines OtherModule (let's say it's a stock Squad module like ModuleParachute)

ModuleParachute otherModule = (ModuleParachute)part.Modules["ModuleParachute"];

otherModule.bar = 10;
