So, you need to generate a lots of different kinds ? Because otherwise, you could to more or less what you describe:
Type Shark
field x,y,z
field speed
End Type
Type Whale
field x,y,z
field speed
End Type
..
etc.
And then, use For s.Shark = Each Shark and For w.Whale = each Whale ?
Type Shark
field x,y,z
field speed
End Type
Type Whale
field x,y,z
field speed
End Type
..
etc.
And then, use For s.Shark = Each Shark and For w.Whale = each Whale ?
