Challenge 4 - Soccer Scripting (Adapted for Unity EdLab)

• Open your Prototype 4 project
• In your File Explorer, select the drive named “Unity Projects and Assets”. Navigate to CreateWithCode > Unit 4 - Gameplay Mechanics > Challenge 4 - Soccer Scripting. Double-click the “Challenge-4_Start” package to import.
• In the Project Window > Assets > Challenge 4 > Instructions folder, use the Challenge 4 - Outcome video as a guide to complete the challenge

When you import the challenge into your project, it is supposed to have bugs.

The purpose of the challenge is for you to fix those bugs, which are listed below. There are also hints at the bottom of the page to help you if you get stuck.

If you cannot fix the bugs and wish to delete the challenge files from your project, in the Project window, right-click on Assets > Challenge 4 and select Delete.

Good luck!

• When you hit an enemy, it should send it away from the player

• A new wave should spawn when all enemy balls have been removed

• The powerup should only last for a certain duration, then disappear

• One enemy should be spawned in wave 1, two in wave 2, three in wave 3, etc

• The enemy balls should go towards the “Player Goal” object

• The player should get a speed boost whenever the player presses spacebar - and a particle effect should appear when they use it

• The enemies’ speed should increase in speed by a small amount with every new wave

• When you hit an enemy, it should send it away from the player
  Hint - In PlayerControllerX.cs, to get a Vector away from the player, you should subtract the [enemy position] minus the [player’s position] - not the reverse
• A new wave should spawn when all enemy balls have been removed
  Hint - In SpawnManagerX.cs, check that the enemyCount variable is being set correctly
• The powerup should only last for a certain duration, then disappear
  Hint - In PlayerControllerX.cs, the PowerupCoolDown Coroutine code looks good, but this coroutine is never actually called with the StartCoroutine() method
• One enemy should be spawned in wave 1, two in wave 2, three in wave 3, etc
  Hint - In SpawnManagerX.cs, the for-loop that spawns enemy should make use of the enemiesToSpawn parameter
• The enemy balls should go towards the “Player Goal” object
  Hint - There is an error in EnemyX.cs: “NullReferenceException: Object reference not set to an instance of an object”. It looks like the playerGoal object is never assigned.
• Bonus - The player should get a speed boost whenever the player presses spacebar - and a particle effect should appear when they use it
  Hint - In PlayerController, add a simple if-statement that adds an “impulse” force if spacebar is pressed. To add a particle effect, first attach it as a child object of the Focal Point.
• Bonus - The enemies’ speed should increase in speed by a small amount with every new wave
  Hint - You’ll need to track and increase the enemy speed in SpawnManagerX.cs. Then in EnemyX.cs, reference that speed variable and set it in Start().

If you want, you can challenge yourself even more by attempting to add special bonus features to your main prototype, which range from Easy to Expert in difficulty.

These extra bonus challenges are entirely optional. If you are not interested and just want to continue with the course, simply mark this step complete and move on to the next tutorial.
