MiniGameManager

Code updated 9/17/2020

To complete Project 1: Create The following GameObjects:

MiniGameManager: Empty GameObject

ResultsPanel Page:

• ResultsPanel: UI-Panel with CanvasGroup Component

• ResultsText: UI-Text - child of ResultsPanel

StartButton Page:

• StartButton: UI-Button

MiniGameManager.cs

This script will be on emptyGameObject: MiniGameManager You'll need to populate public fields in the inspector once you have created the other required gameObjects. See Images below:

Put Script on an empty gameObject in the Scene.

Overview - MiniGameManager.cs:

The MiniGameManager Class manages logic for:

• Start Button to Start Gameplay

  • Function ReStartGame( ) is executed when the StartButton is clicked

    • Resets GameData

    • Hides the Results Panel:

    • Sets the curGameState to MiniGameState.active

    • Hide the StartButton so it's inactive (hidden)

    • Set the Spawner activeSpawning = true

    • Execute Spawner StartSpawning( ) method.

• Polling - Code Executed in Update( ): - Checked Every Frame

  • Checks to determine what the current value of curGameState

  • if curGameState ==MiniGameState.active

    • Check that Health is still greater than 0

    • If Health is Greater than 0

      • Check Score, if Score > WinScore

        • Set MiniGameState.Win

        • Set win text for ResultsText.text

        • Call GameOver( )

    • Else if Health is Less than or equal to 0

      • Set MiniGameState.Lose

        • Set lose text for ResultsText.text

        • Call GameOver( )

• GameOver( ) Method

  • Show ResultsPanel ( Use Utility to set CanvasGroup values)

  • Show StartButton - setActive is true, makes visible

  • Stop Spawner by activeSpawning = false

  • Spawner: StopAllSpawning( ) Also destroys all spawned objects
