Overriding static constructors

[fireundubh]

Any idea how to override static constructors (e.g., Game.Scripts.Scripts())?

Kinda behind on github notifications, sorry! We've been majorly refactoring. You can for sure override them, but it's slightly weird. In CECIL terms, static constructors are .cctor so you have to create a pair of methods for it. It'll look something like this:

[MemberAlias(".cctor", typeof(object))]
private void object_cctor() {
    //this is an alias for object::.cctor()
}

[ModifiesMember(".cctor")]
public void CCtorNew() {
    object_cctor(); //call the old static constructor if you want
    //do the new stuff here
}

[fireundubh]

Tried that. I get this error when compiling:

error CS1729: 'Scripts' does not contain a constructor that takes 0 arguments

[SonicZentropy]

It's a compiler annoyance because 'Scripts' doesn't have a NON-static parameterless constructor, which is what the compiler tries to call in the absence of a defined one.

You can read more about it here: https://stackoverflow.com/questions/7230544/c-sharp-error-parent-does-not-contain-a-constructor-that-takes-0-arguments

The way I work around it is by using [ModifiesType("Scripts")] attribute above your class declaration, then NOT directly inheriting from Scripts

[fireundubh]

NOT directly inheriting from Scripts

Does that mean I have to reimplement the entire Scripts class?

[SonicZentropy]

No, the [ModifiesType] Attribute will pull it into the right place anyway

I'm still have trouble with this.

Here's the mod: Change Strength Patch Mod.

Just some background: The mod is meant to be used in conjunction with a .gamedatabundle file to allow modifying disposition, reputation, and relationship change strengths independently.

The launcher is now throwing this exception:
