Hi, is it possible to add an external secondary constructor for a class ?

I have a typealias AABB = Rectangle with an external "constructor" fun Rectangle(x: Int = 0, y: Int = 0, width: Int = 0, height = 0) = ... but it's not present on the type AABB, I also tested with fun Rectangle.invoke(x: Int ... but it still doesn't work, is it possible ?

If the class has a companion object, then you can make an extension on the companion which looks like a constructor: fun Rectangle.Companion.invoke(...): Rectangle

[Ruckus]

You can just make a to level fun Rectangle(...) (or fun AABB(...))

[Ayfri]

Oh yes the invoke has to be on the Companion object, it kinda works, as I can't directly do val a = AABB() but val a = AABB.invoke()

[Ayfri]

I just forgot operator, it works thanks x)

fun with similar name, suggested by @Ruckus is more flexible solution in this case
