Updateing Framecount individually?

I don't think I understand. I create bombs with this.

	Function CreateBomb() 
		If not TTile.List
			TTile.List = CreateList() 
		End If
		Local b:TTile = New TTile
		b.BombFRame = 0
		b.BombFrameTimer = MilliSecs() 
		TTile.List.AddLast(b) 
	End Function

And if MapArray[x,y].frame = 0, I TTile.createbomb()
