Create With Code Unit - 2 | Unity Version 6000.3.4f1

So what things did I learn from this unit??

• Learned how to spawn or shoot projectiles after a key is pressed.
• Learned how colliders work in Unity.
• Learned how to spawn objects randomly on any given location range.

Major Programming Concepts Learned

• Learnt how to use the Instantiate function. Implemented in SpawnManager
• Learnt how to keep the player in bounds using if statements.
• Learnt how to use InvokeRepeating.
• InvokeRepeating can be used to invoke a function repeatedly with a given time interval. Implemeted in SpawnManager
• Also learned about how we can use Random.Range. But we have to be careful while using this because we cannot use it in an initialization of a global variable, you have to use locally inside a function. For some reason this happens only in a class derived by MonoBehaviour class.

Completed the challenge and Solved all the Bugs

Dogs are spawning at the top of the screen

• Solution: Dogs were spawning on the top because the dog game object was added in the place of ball.

The player is spawning green balls instead of dogs

• Solution: Click on Player and change the game object to dog in the inspector.

The balls are destroyed if anywhere near the dog

• Solution: The collider for the dog is too big, we have to adjust it properly!

Nothing is being destroyed off screen

• Soltion: In DestroyOutOfBoundsX.cs we have change the variables to leftLimit = -45 & bottomLimit = -5 and also change the if conditions to if (transform.position.x < leftLimit) & else if (transform.position.y < bottomLimit)

Only one type of ball is being spawned

• Solution: We have to change a few things in the SpawnManagerX.cs
• Initialise a new variable inside SpawnRandomBall, int randomIndex = Random.Range(0, ballPrefabs.Length); and add that in the Instantiate

Bonus: The spawn interval is always the same

• Solution: To change the spawn interval in SpawnManagerX.cs we have just add anew line before we call InvokeRepeating. We should add this line float spawnInterval = Random.Range(1.0f, 2.5f);.

Bonus: The player can “spam” the spacebar key

• Solution: We should add a cooldown as given in the PlayerControllerX.cs

Thank you for reading this far!
