Hi,I am trying to create (MAIN) objects dynamically and these objects are then going to have a list of dynamic (SUB) objects. My problem is that I don't know how to create X amount of sub objects (bombs) for 1 main object. At least as comment suggests I have an idea but it doesn't work and I...

Isn't it obvious? If you want to create a loop with new Bomb and create count bombs, you also need to call it to the list count times. You are creating instanced of a Bomb, but those instances become unreachable at the end of your '{...}' scope, so eventually they are destroyed by the Garbage...

When you create an object the system always calls the base constructor (if it exists) before any derived constructors, so that the base object is fully constructed and read for use before any add-on code tries to use it. Think of it like this: if the base class was not constructed first, then...
