Time for action — the ActivateShield method


  1. 1. The new method will be called ActivateShield.

    Method ActivateShield:Int()
    

    The shield object is already created, so we just want to make it active. As we want it to be deactivated after 5 seconds, we need to create a timer to do this.

  2. 2. Create a new object timer. The parameters are the shield object, the timer ID tmShieldTime, and when it should fire (in 5000 milliseconds).

    eng.CreateObjTimer(g.shield, g.tmShieldTime, 5000)
    
  3. 3. While the shield is active, the player ship should not take any collisions.

    g.player.SetColGroup(0)
    
  4. 4. Set the shield to active and close the method.

    g.shield.SetActive(True)
    Return 0
    End
