  2. When the game mode is gmPlay, update the engine with the deltaTime divided by 60 as a speed parameter.
    Case gmPlay
eng.Update(Float(UpdateGameTime())/60.0)
  3. Do a collision check only on the layerGame layer.
    eng.CollisionCheck(layerGame)
  4. Update the info text objects.
    UpdateInfoText()
  5. When the game mode is gmMenu or gmGameOver.
    Case gmMenu, gmGameOver

    If the P key was hit, then start a new game. 

    If KeyHit(KEY_P) Then
StartNewGame()
Endif

    If the H key was hit, then show the high score list. 

    If KeyHit(KEY_H) Then
ShowScoreList()
Endif
  6. When the game mode is gmScoreList.
    Case gmScoreList

    If the P key was hit, start a new game.

  7. End the Select statement.
    End
Return 0
