Map Container used for multiple Instances

I have two questions.

I am wondering if i can use an IntMap, or another Container to hold multiple Instances of a variety of Classes. Right now i have something like this.

Class UnitClass
	Method OnCreate()
	Print("make one more instance of Units")
	End
	
	Method Say()
	Print("Say something")
	End
End

Function Main()
	Local Units:IntMap<UnitClass> = New IntMap<UnitClass>
	
	For Local i:Int = 0 To Rnd(9)
		Units.Add(i, New UnitClass)
	Next
	
	For Local i:Int = EachIn Units.Keys()
		Units.Get(i).Say()
	Next
End

Maybe i am going about this the wrong way. But what i would like to do is have different classes that inherit UnitBase and store them in my IntMap. Say a Class for a Zombie, and then a class for a Orc, ect. That way all of my instance for the monsters in the game are stored in a single container.

Also when i create and Instance i notice that OnCreate() is not run.

Thanks.

Wait. I can use a variety of IntMaps, one for each Class i would like to store, and contain the IntMaps inside a StringMap. I think... I would still like some feed back in case i am overthinking or underthinking what i am trying to do.

Thanks.

Hi,

Use inheritance to store multiple 'subclasses' of a class in the same container, eg:

Class Unit
   Method Update()...blah
End

Class Zombie Extends Unit
   Method Update()...blah
End

Class Pixie Extends Unit
   Method Update()...blah
End

Global Units:=New IntMap<Unit>

Function Etc()
   Units.Set 0,New Unit
   Units.Set 1,New Zombie
   Units.Set 2,New Pixie
End

'Extends' means that a class 'is a kind of' some other class, so you can use it whether the other class is expected.

Also, use Method New() to construct objects - OnCreate() is just for the Mojo App.
