Portal

Objectives

  • Create your own level in a new scene using ProBuilder and ProGrids!
  • Ensure that the level has an FPSController to navigate with in the scene.
  • Ensure that there is an object or region with a trigger at the very end that will trigger the end of the level (some zone with an invisible BoxCollider will work).
  • When the level ends, display “You Won!” on the screen with a Text object.

Getting Started

Download the distro code for your game from cdn.cs50.net/games/2018/x/projects/10/portal.zip and unzip portal.zip, which should yield a directory called portal.

Then, in a terminal window (located in /Applications/Utilities on Mac or by typing cmd in the Windows task bar), move to the directory where you extracted portal (recall that the cd command can change your current directory), and run

cd portal

Becoming a Pro

Welcome to your eleventh and final regular assignment! This assignment is going to be a fun conclusion to what’s been a challenging but hopefully exciting term! Rather than build upon Portal in this example, and to afford you some extra time for your final project (and hopefully save a little stress!), we’re going to leverage some of Unity’s brand-new tools to create a level! ProBuilder and ProGrids are a key feature that’s changed the game for Unity, and having them makes creating game worlds (and more!) all the easier.

Specification

  • Create your own level in a new scene using ProBuilder and ProGrids! The distro should already have ProBuilder and ProGrids imported and ready for use, but just in case they aren’t, you can easily find them by searching in the Asset Store (where they are now free, thanks to Unity having acquired them!). There are many resources for learning how to use ProGrids effectively, but two resources in particular that are worth checking out are here and here, which should more than prepare you for creating a simple level.
  • Ensure that the level has an FPSController to navigate with in the scene. This part’s probably the easiest; just import an FPSController from the Standard Assets! It should already be imported into the project in the distro, where you can find the prefabs under Assets > Standard Assets > Characters > FirstPersonCharacter > Prefabs!
  • Ensure that there is an object or region with a trigger at the very end that will trigger the end of the level (some zone with an invisible BoxCollider will work). This one should be easy as well, just relying on the creation of an empty GameObject and giving it a BoxCollider component, which you can then resize via its resize button in the component inspector!
  • When the level ends, display “You Won!” on the screen with a Text object. Recall that OnTriggerEnter is the function you’ll need to write in a script you also associate with the BoxCollider trigger, and ensure that the BoxCollider is set to a trigger in the inspector as well! Then simply program the appropriate logic to toggle on the display of a Text object that you also include in your scene (for an example on how to do this, just see the Helicopter Game 3D project, specifically the GameOverText script)!

How to Submit

  1. If you haven’t done so already, visit this link, log in with your GitHub account, and click Authorize cs50. Then, check the box indicating that you’d like to grant course staff access to your submissions, and click Join course.
  1. Using Git, push your work to https://github.com/me50/USERNAME.git, where USERNAME is your GitHub username, on a branch called games50/projects/2018/x/portal or, if you’ve installed submit50, execute

    submit50 games50/projects/2018/x/portal
    

    instead.

  2. Record a screencast, not to exceed 5 minutes in length (and not uploaded more than one month prior to your submission of this project) in which you demonstrate your app’s functionality. Upload that video to YouTube (as unlisted or public, but not private) or somewhere else.
    • To aid in the staff’s review, in your video’s description on YouTube, you should timestamp where each of the following occurs in your gameplay demonstration. This is not optional; failure to do this will result in your submission being rejected:
      • “You win” (or similar) message shows
  3. Submit this form.

You can then go to https://cs50.me/cs50g to view your current progress!
