Why doesn't this if-statement work?
I'm creating a game where you click boxes and gain points by doing so. I want to create new boxes when the game starts and when the box gets destroyed. Instead, this script just creates new boxes every frame. I don't know why this doesn't work, maybe I'm doing it all wrong, I'm pretty new to Unity and c#.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class BoxScript : MonoBehaviour {
private bool boxExists = false;
private Vector3 startPos = new Vector3(-10, 0, 0);
public GameObject box;
private void Update() {
if (!boxExists) {
Instantiate(box, startPos, Quaternion.identity);
Destroy(box);
boxExists = true; }
}
}
What gameObject is box ? Is a gameObject holding the BoxScript? If so, it's probably because the newly instantiated box run once the Update function, and thus, creates a new box before it's itself destroyed.
Hi there. Don't quote me on this but I'm pretty sure it's not working because you are using Update(). Update executes so quickly that your code won't even get to 'boxExists = true', so basically it always equals false and creates a new box using 'Instantiate'. Try changing your code to this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class BoxScript : MonoBehaviour {
private bool boxExists = false;
private Vector3 startPos = new Vector3(-10, 0, 0);
public GameObject box;
private void Start()
{
InvokeRepeating("YourMethod", 0f, 0.05f);
}
private void YourMethod() {
if (!boxExists) {
Instantiate(box, startPos, Quaternion.identity);
Destroy(box);
boxExists = true; }
}
}
'YourMethod' you can change to what you want, and '0.05f' is how long until 'YourMethod' will be executed again. Try that and let me know if it works. :D
Thanks for replying @HyperGamer87 ! I will try the code and let you know if it worked.
@HyperGamer87 I have implemented your code to my game and now it works perfectly, thanks a lot!
