Tipps and tricks

Serialising Components

Always serialize what you need not the whole gameObject

[SerializeField] AudioSource _carrotPrefab;
...

void Update(){
    if(Input.GetKeyDown(KeyCode.Space)){
        var audioS = Instantiate(_carrotPrefab,transform.gameobject);
        audioS.playAudiOneShot();
    }
}

Draw gizmos

To keep track of positions in the screen we can draw

private void OnDrawGizmos(){
    Gizmos.color = Color.green;
    Gizmos.DrawSphere(_variable,0.4f);
}

Calling Scripts

Rule of thumb is never call other scripts in awake. Only initialise yourself in awake

Variable scope

The goal is to lock your scripts down as much as possible so don't make components available for the outside unless they really need to.

So instead of setting variables public that you need to be accessed from outside you should create a getter

//Read only for external scripts
int CarrotsSpawned {get;private set;}
//To serialize it you need to add a serialize field
[field:SerializeField] int CarrotsSpawned {get;private set;}

//The shorthand version of that is
public Carrot CarrotPrefab => _carrotPrefab

Iterating through collection with Modulo

If you want to iterate through a collection and want to set the index back at the end

private int _clipIndex;

_clips[_clipIndex++%_clips.Length]

Set Position and Rotation with one call

transform.SetPositionAndRotation(Vector3.zero,Quaternion.identity);

Composition

Try to keep your scripts as single purposed as possible.

Variable Naming

Make your public variables capital public int Variable Make your private variables underscore private int _anotherVariable And the local variables in a function non underscore camelcase var aThirdVariable
