Nodes.

Trying this, wanting to have a list of paths, each path in the list has an ID,Name and then a list of nodes.

But the code bellow is giving me an error, cannot call m_AddLast2() of null, or something to that effect, happens at runtime.

am I doing something crazy with the lists. ?

Global Paths:List <cPath> = New List<cPath>

Global PathNodeImage:Image  

Const SPAWN : Int = 1
Const DEATH : Int = 2

Class cPath
	'a path holds a list of nodes.
	Field id	:Int
	Field name	:String
	Field node	:List<cNode>	
	
	Method New(id:Int,name:String)
		Self.name=name
		Self.id=id
		Paths.AddLast(Self)	
	End Method
	
	Method AddNode(x:Float,y:Float,a:Float,ms:Float,ts:Float,id:Int,t:Int=0)
		Local tn:cNode = New cNode()
			tn.x=x
			tn.type=t
			tn.y=y
			tn.angle=a
			tn.movespeed=ms
			tn.turnspeed=ts
			tn.id=id
		Self.node.AddLast(tn)	
	End Method
	
	Method Draw()
		For Local dn:cNode = Eachin Self.node
			DrawImage(PathNodeImage,dn.x,dn.y,dn.angle,1,1,0)
		Next
	End Method
	
End Class

Class cNode
	
	Field x:Float ' nodes position
	Field y:Float ' nodes position
	Field angle:Float ' the angle the ships takes from the node.
	Field movespeed:Float ' the speed the ship takes from the node
	Field turnspeed:Float ' the turnspeed used by the ship (this can be ignored and hard coded.) 
	Field type:Int ' 1 is a spawn point. 2 is the kill point. 0 is a normal node point.
	Field id:Int 'each step in the path has a number. should be in order.
	
End Class

You haven't constructed the list.

Field node:List<cNode> = New List<cNode>
