GetComponent sometimes doesn't work
First of all, hi, this is my first question on the forums and I'm also new to Unity (and programming).
Now, my problem is this: I need to access a variable from another script but for some weird reason it won't work.
This is the script that needs to access the variable:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class updateWood : MonoBehaviour
{
public Items itemsScript;
public UnityEngine.UI.Text textC;
private RectTransform rt;
private int wood = 0;
private int nWood = 0;
// Start is called before the first frame update
void Start()
{
itemsScript = rt.parent.parent.parent.GetComponent<Items>().itemsScript;
rt = this.GetComponent<RectTransform>();
}
// Update is called once per frame
void Update()
{
nWood = itemsScript.wood;
}
And this is the script that contains the variable:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Items : MonoBehaviour
{
public Items itemsScript;
void Awake()
{
itemsScript = GetComponent<Items>();
}
}
I know that should work because other scripts can access the same variable without problem, but oddly if I comment the itemsScript = rt.parent.parent.parent.GetComponent<Items>().itemsScript; line and change nWood = itemsScript.wood; with nWood = rt.parent.parent.parent.GetComponent<Items>().wood; everything works as intended.
I am clueless and this is killing me right now. Thanks in advanve
In your Start() in the first script, you need to reverse the order of the two rows you have there... rt need to be assigned before you can use it.
rt = this.GetComponent<RectTransform>();
itemsScript = rt.parent.parent.parent.GetComponent<Items>().itemsScript;
omg you are right, I'm sorry for making such a dumb question. And thanks a lot!
By the way, can I make you another question if it is regarding GetComponent or should I open another thread instead?
Open a new thread if you think it's a new question. just remember to check google or UnityAnswer if there's someone who might already answered your question
