function and methods

right or wrong i don't know, but basicly how i would do it is:

if i want it to be called from outside the type i use a function, and if i want it to be called from inside the type i use a method.

here is a VERY BASIC example of what i mean

Graphics 800,600

'gfx
Global enemy:timage = LoadImage("enemypic.png")


'list to hold the enemies
Global EnemyList:TList = CreateList()

'***********************MAIN LOOP**************************
While Not KeyDown(key_Escape)
	Cls
	
	'call the CreateEnemy function if 'E' is pressed
	If KeyHit(key_E) Then TEnemy.CreateEnemy(Rand(100,700),Rand(100,500))
	
	'call the Update function for TEnemy
	TEnemy.Update()
	
	Flip
Wend
End
'**********************************************************


Type TEnemy()
	Field x#,y#			'current position
	Field tx#,ty#		'move target position
	Field ismoving		'is the enemey moving?
	
	Function CreateEnemy:TEnemy(x#,y#)
		'stuff to create an enemy goes here
		
		Local e:TEnemy = New TEnemy
		
		e.x# = x#
		e.y# = y#
		
		EnemyList.AddLast e
	End Function
	
	Method Move()
		'very basic move structure
		
		If Self.x# < Self.tx# Then Self.x#:+0.5
		If Self.x# > Self.tx# Then Self.x#:-0.5
		If Self.y# < Self.y# Then Self.y#:+0.5
		If Self.y# > Self.y# Then Self.y#:-0.5
		
		If Self.x# > Self.tx# And Self.x# < Self.tx# Then Self.x# = Self.tx#
		If Self.y# > Self.ty# And Self.y# < Self.ty# Then Self.y# = Self.ty#
		
		If Self.x# = Self.tx# And Self.y# = Self.ty# Then Self.ismoving = 0
	End Method
	
	Method GetMoveTarget()
		'get new target for enemy to move to
		
		Self.tx# = Rnd(100,700)
		Self.ty# = Rnd(100,500)
		Self.ismoving = 1
	End Method
	
	Method Draw()
		'draw enemy image here
		
		DrawImage enemy,Self.x#,Self.y#
	End Method	
	
	Function Update()
		For Local e:TEnemy = EachIn EnemyList			
			'call the Draw method for this particular enemy
			
			e.Draw()
			
			If e.ismoving = 0
				'call the GetMoveTarget method for this particular enemy
				
				e.GetMoveTarget()
			Else
				'call the Move method for this particular enemy
				
				e.Move()
			End If
		Next
	End Function
End Type

i hope that helps some
