Example

The following example is a simulation to visually mimic the appearance of randomly moving worms. 100 Bot objects are created and corresponding properties modified when the OnSimBegin event is triggered at the beginning of the simulation. Then for each time step, the OnSimStep event is triggered, which randomly moves the Bot objects.

Private Sub World1_OnSimBegin(ByVal World As World, ByVal Worms As Bots, ByVal Cells As Cells)
    World.Screen.Resize 350, 350
    World.Screen.BackColor = vbBlack
    World.Screen.FadeRate = 0.04
    Worms.Create 100
    Worms.Shape = vbtPoint
    Worms.Color = vbBlue
    Worms.Size = 3
    Worms.Pen.ColorRand
    Worms.Pen.Width = 2
    Worms.Pen.Down
End Sub

Private Sub World1_OnSimStep(ByVal World As World, ByVal Worms As Bots, ByVal Cells As Cells)
    Worms.TurnRand -30, 30
    Worms.Step 1
End Sub
