Function Overload its possible?

BlitzMax Forums/BlitzMax Beginners Area/Function Overload its possible?

Hi guys!
So Im trying to create to constructors for may objetc see:
Type TObject
       List:TList
       Field x%, y%
	Function Create:TObject()
		Local in:TObject
		in = New TObject
		If Not List Then List = New TList
		List.AddLast(in)
		Return in
	EndFunction 

	Function Create:TObject(x:Int=0, y:Int=0)
		Local in:TObject = Create()
		in.x = x
		in.y = y
		Return in
	EndFunction 
EndType

Its possible with BMax? Because Im getting a "duplicate function" error.
Thanks in advance

Nope... no function or operator overloading in BlitzMax...

You need to do something like this:

SuperStrict 

Type TObject
	Global List:TList
	Field x%, y%

	Function Create:TObject()
		Local in:TObject = New TObject
		If Not List Then List = New TList
		List.AddLast(in)
		Return in
	EndFunction 

	Function CreateSpecial:TObject(x:Int=0, y:Int=0)
		Local in:TObject = Create()
		in.x = x
		in.y = y
		Return in
	EndFunction 
EndType

For Local i% = 0 To 10
	TObject.CreateSpecial(Rand(100),Rand(100))
Next

For Local o:TObject = EachIn TObject.List
	Print o.x
Next

Method New is automatically called whenever you create the object. It cannot take any parameters but it is useful for adding to lists etc. You can create the TList at the beginning of the program as a global variable - there is no need to check each time.

Type TObject
       Global List:TList = New TList
       Field x%, y%

	Method New()
		List.AddLast(Self)
	EndMethod

	Function Create:TObject(x:Int=0, y:Int=0)
		Local in:TObject = New TObject
		in.x = x
		in.y = y
		Return in
	EndFunction 
EndType

Yeah method New() is really clean to do this, so less code spared betwen my constructors :) Thanks!
