ModuleManager: Create if doesn't exist, don't touch otherwise?

[Sharpy]

I want to make my mod compliant with CommunityResourcePack, but not include it (all the hassle with updates, maintenance, the sheer size of CRP comparing to my mod).

I need one resource that is present in CRP; I'd like to define it if CRP is not present, not touch if CRP is present. What would the syntax be?

Say, if I wanted to "edit or create", I'd write

@RESOURCE_DEFINITION[StoredCharge]
{
    @name = StoredCharge
    @unitCost = 0
    @density = 0
    @flowMode = NO_FLOW
    @transfer = NONE
    @isTweakable = false
    @isVisible = true
    @volume = 1
}

But what I want is "Create Or Leave Alone"?

@Sharpy I believe this will do what you are looking for:

@RESOURCE_DEFINITION[StoredCharge]:NEEDS[!CommunityResourcePack]

That tells MM only to load if CRP is not present.

@Randazzo: Thanks, works!

Would not % be the create or edit operator, vs @? I thought the latter only edits if exists? I often get this backwards though  

there is another rare operator that would work, &, but I would have to check the details, and the above solution with needs is way cleaner. (But there are more options then people realize with MM  )

The & operator unfortunately doesn't work with root-level nodes (yet).  But it would be what you want - create the node if it doesn't exist, otherwise don't touch it.

You would have to watch if Near Future Technologies is installed also has that is where it's from it's used in the capacitors charge
