Time for action — setting up the player ship


  1. 1. Add a new method called CreatePlayer to the game class.

    Method CreatePlayer:Int()
    
  2. 2. Set the player object by calling CreateImage with our texture atlas. The positioning doesn't matter because we will do this later on.

    player = eng.CreateImage(atlas,0,0,32,32, 0,0)
    
  3. 3. Now, set the friction and the maximum speed of the ship.

    player.SetFriction(0.2)
    player.SetMaxSpeed(20.0)
    
  4. 4. To have the ship automatically wrap around the screen when it reaches its edges, set the wrapping to True via SetWrapScreen.

    player.SetWrapScreen(True)
    
  5. 5. Reset the layer of the player object to layerGame.

    player.SetLayer(layerGame)

    player.SetColGroup(grpPlayer)
    player.SetColWith(grpComet, True)
    player.SetRadius(12)
    
  7. 7. Now, set the player ship to...
