Time for action — detailing the OnLayerTransition method


For this, we need to detail the OnLayerTransition method of the engine class, as follows:

  1. 1. First, we check if the transition ID is equal to g.tidNextLevel.

    Method OnLayerTransition:Int(transId:Int, obj:ftLayer)
    If transId = g.tidNextLevel Then
    
  2. 2. Then, reset the alpha value of the layer back to 1.0. That means it would be fully visible.

    g.layerGame.SetAlpha(1.0)
    
  3. 3. Next, check whether the current level number is smaller than 4 (we have only four levels).

    If g.levelNum < 4 Then
    
  4. 4. Raise the current level number and load a new level.

    g.levelNum+=1
    g.LoadLevel()
    
  5. 5. Switch the game mode back to g.gmPlay.

    g.gameMode = g.gmPlay
    
  6. 6. If the last level is already reached, activate the title layer.

    Else
    g.layerTitle.SetActive(True)
    
  7. 7. Set the game mode to g.gmMenu and close off the two If checks.

    g.gameMode = g.gmMenu
    Endif
    Endif
    Return 0
    End
