declare class UObject {
constructor();
constructor(Outer: UObject);
}
declare class Actor extends UObject {
constructor(InWorld: World, Location?: Vector, Rotation?: Rotator);
}

with constructor functions defined above, it can pass some parameters as follow:

class MTestActor extends Actor{
}
let act = new Actor_C(GWorld, {Z:200});

but, how can i pass customer parameters while constructing?

Actor_C that be created by uclass is unreal class.
It can't be get more custom parameter by override constructor.
Only way is that use lazy-initialization.

class MyActor extends Actor {
            ctor() {
                console.log('ctor')
            }
            lazy_ctor(...params) {
                console.log('lazy_ctor', this, params)
            }
        }
        let MyActor_C = require('uclass')()(global,MyActor);
        let d = new MyActor_C(GWorld, {Z:100});
        d.lazy_ctor([1,2,3]);
