ASTEROIDS - RANDOM SPAWN

INSTANTIATE RANDOM ASTEROIDS

• This section discusses on how the random (out of 3 prefabs) asteroids were instantiated at random x-position using asteroid prefabs' rotation.

RANDOM INDEX FOR ARRAY

• It is necessary to create a random index for an array so that every time the Game Object is instantiated, a random Index in fed into the code and random asteroid clone is created.

• For this, Random.Range(int minInclusive, int maxExclusive) was used. 

  • • This method is used to return a random int within [minInclusive and maxExclusive]

    • In this case, minInclusive number = 0, and 

    • maxExclusive number = Array.Length (Length of an array or number of elements stored in an array)

RANDOM SPAWN POSITION

• The random asteroids should spawn from random x-position. However, y and z position is fixed. 

• To get random x-position, a Random.Range() method was used again. 

• The random x-position, and y and z -position were then used to create a new Vector3. This was stored in a Vector3 variable randomSpawnPosition.

INSTANTIATE

• Both, the randomIndex for random asteroid instantiation and randomSpawnPosition was created. 

• Now, using Instantiate() method, random asteroids were instantiated.

SpawnAsteroids() method

• To make the script more readable, a new method SpawnAsteroids() was created that would just handle the random instantate function of asteroids.
