How to sort Array of GameObjects by Enum

Questions & Answers
1

Hello,

I have GameObjects in an array found by a tag in a certain distance. I have an enum of conditions:

public enum Condition
{
    Critical = 10,
    Moderate = 25,
    Barely = 50
}

I want to sort them by most important ones e.g.

Barely
Barely
Moderate
Critical

and after that do something with them from 1st to last. How can I achieve that? Would appreciate if anyone would explain the best approach for this, here is the code:

protected void CheckForCloseBodies(string tag, float minimumDistance)
{
    GameObject[] goWithTag = GameObject.FindGameObjectsWithTag(tag);
    var newCurrentHealth = 0.0f;

    for (int i = 0; i < goWithTag.Length; ++i)
    {
        var bodyDamageHandler = goWithTag*.GetComponent<vp_DamageHandler>(); // Dead Bodys*

var bodysCondition = goWithTag*.GetComponent();*
var convertedHealth = bodysCondition.checkScavangeCondition();
if (Vector3.Distance(transform.position, goWithTag*.transform.position) <= minimumDistance)*
{
if (transform.position != goWithTag*.transform.position)*
{
if (bodyDamageHandler.IsDead == true)
{
if (bodysCondition.AbleToScavenge == true)
{
newCurrentHealth = PlayerDamageComponent.CurrentHealth + convertedHealth;
if (goWithTag.Length > 1)
{
// HERE IT SHOULD SORT THEM
}
else
{
if (newCurrentHealth <= PlayerDamageComponent.MaxHealth)
{
Debug.Log(PlayerDamageComponent.CurrentHealth = newCurrentHealth);
bodysCondition.scavangableHealth = 0.0f;
}
else
{
if (!isFullHealth)
{
bodysCondition.scavangableHealth = newCurrentHealth - PlayerDamageComponent.MaxHealth;
newCurrentHealth = newCurrentHealth - bodysCondition.scavangableHealth;
}
}
}
}
}
}
}
}
}
Thank you

Maybe your design could be improved. Ordering can be expensive and in your case, you are not really ordering, more likely arranging by type (ok quite similar).

I would rather have 3 different lists each containing the corresponding type. If an object is changing its type then it is also changing the collection it belongs to.

private Condition condition = Condition.None; // or any default
private Manager manager  = null; // Get a ref in start

public Condition ObjCondition {
    get{return condition;}
    set{
        if(condition!=value){
             condition = value;
             List<GameObject> typeList = manager.GetList(value);
             typeList.Add(this.gameObject);
        }
    }
}

in the manager:

private Dictionary<Condition, List<GameObject>> dict = new Dictionary<Condition, List<GameObject>>();

void Awake(){
    dict.Add(Condition.Critical, new List<GameObject>());
   // Same for others
}

public List<GameObject> GetList(Condition condition)
{
     return dict[condition];
}

The needing methods get a reference to the list by condition and only those objects so you don’t even have to check when it changes condition in the collection.
