Class override

[marcotrumpet]

Hi,
is there a way to intercept a class so that every time someone calls that type I can inject a specific fields in the constructor?

Nope, Il2Cpp is purely static - but would you elaborate on "intercept a class", "calls that type" and "inject a specific fields in the constructor"?

Sure, so let's say I have

public class Class1
{
	// Fields
	private int field1;

	// Methods
	public double method1() { }
}

Class 1 is referred by many other methods in other classes and I don't want to override all of those methods.
I was wondering if there was a way to override field1 value every time Class1 constructor is called.

Don't know if it's clear enought

Ok, now it is! You just have to define a custom implementation for the constructor(s) of that class (the constructor method name is .ctor):

Class1.method(".ctor").implementation = function (...args: any[]) {
  this.method(".ctor").invoke(...args);
  this.field<number>("field1").value = 666;
}

So do I need to invoke and then set the new value for the field? Also the args list is like a default parameter or I need to add my own?

...args: any[] is a TypeScript syntax, which allows you to represent an indefinite number of arguments as an array. Therefore, you don't need to fill in any specific arguments in the ...args: any[] part, as it will automatically collect all arguments passed to the method into an array.
