How to select a gameobject from a UI list and do something with it-CodePudding

I have a list of gameObjects(NPCs) instantiating on a UI scrollable panel. I want to be able to click on their name and assign them to the building for example. here's what I have so far:

 HumanPool playerPool;

 [SerializeField] GameObject PlayerInfo;

 [SerializeField] TextMeshProUGUI playerName;

 [SerializeField] Transform SpawnPoint;

 void Start()
 {
     playerPool = FindObjectOfType<HumanPool>();
 }

 void updateListOfHumans()
 {
     SpawnPoint.DetachChildren();

     for (var i = 0; i < playerPool.Humans.Count; i  )
     {

         Vector3 pos = new Vector3(0, 0, SpawnPoint.position.z);

         playerName = PlayerInfo.GetComponentInChildren<TextMeshProUGUI>();

         playerName.text = playerPool.Humans[i].name;

         GameObject SpawnedItem = Instantiate(PlayerInfo, pos, SpawnPoint.rotation);

         SpawnedItem.transform.SetParent(SpawnPoint, false);
     }
 }
void OnMouseDown()
 {
     updateListOfHumans();
 }

I'm pretty sure that when I click on a playerName (child of a button) there should be an onClick() function that will do something. But I have no idea how to get that specific ID of a NPC and how to target him/her.

Here's also the relevant code from HumanPool:

List<Human> humans = new List<Human>();
public List<Human> Humans { get { return humans; } }

Humans are generated in a pure C# constructor class:

public class Human {
public string name;

public Human(string name)
{
    this.name = name;
}}

Should I add an ID variable in a constructor class and target clicked NPC with that?

My biggest problem here is how to tell the next method which NPC is chosen from a list and and that he/she should go work in that building.

Sorry for the possibly bad explanation but I really hope it makes some sense of what I'm trying to do here... Quite new with Unity so any help would be greatly appreciated.

Thank You!

CodePudding user response：

Guess you are using a UI.Button component.

In that case there is indeed the onClick event you could simply add a callback to like e.g.

var human = playerPool.Humans[i];
var button = spawnedItem.GetComponentInChildren<Button>();
button.onClick.AddListener(() => OnClickedHuman(human));
// You also want to do this rather on the spawned item, not the prefab btw
var text = spawnedItem.GetComponentInChildren<TextMeshProUGUI>();
text.text = human.name;

and then have

private void OnClickedHuman (Human human)
{
    // Do what you want with human
    Debug.Log($"Clicked on {human.name}!", this);
}
