I'm stuck in Application.EnterPlayMode-CodePudding

I put this script in, this message pops up and I can't go next

Unity 2021.3.15f1

Windows 10

Project name: 포둥

application.enterplaymode/ wating for Unyty's code to finish excuting

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class podungsay : MonoBehaviour
{
    public GameObject Textbox;
    public bool sayingf;
    public UnityEngine.UI.Text sayingtext;
    public GameObject openmouth;
    public GameObject closemouth;

    IEnumerator OnType(float interval, string Say, float wait)
    {
        sayingf = true;
        foreach (char item in Say)
        {
            sayingtext.text  = item;
            yield return new WaitForSeconds(interval);
        }
        yield return new WaitForSeconds(wait);
        sayingf = false;
    }

    void Update()
    {
        if (sayingf == true)
        {
            Textbox.SetActive(true);
        }
        else
        {
            Textbox.SetActive(false);
        }
    }

    IEnumerator mouth()
    {
        while (true)
        {
            while (sayingf == true)
            {
                openmouth.SetActive(false);
                closemouth.SetActive(true);
                yield return new WaitForSeconds(0.7f);
                openmouth.SetActive(true);
                closemouth.SetActive(false);
                yield return new WaitForSeconds(0.7f);
            }
            openmouth.SetActive(true);
            closemouth.SetActive(false);
        }
    }

    void Start()
    {
        StartCoroutine(mouth());
    }
}

So I changed the version to 2021.3.17f1 but still got this message What's wrong with the command? (Use Google translator)

CodePudding user response：

It is stuck because you are using a while which never ends. Leading to an infinite loop.

Use the Update() Method instead.

CodePudding user response：

Right here:

IEnumerator mouth()
{
    while (true)
    {
        while (sayingf == true)
        {
            openmouth.SetActive(false);
            closemouth.SetActive(true);
            yield return new WaitForSeconds(0.7f);
            openmouth.SetActive(true);
            closemouth.SetActive(false);
            yield return new WaitForSeconds(0.7f);
        }
        openmouth.SetActive(true);
        closemouth.SetActive(false);
    }
}

When "sayingf" is false, it will set openmouth to be active and closemouse to be inactive, and then it will repeat from the while (true), causing an infinite loop. You need to add a delay. You can use yield return 0 or yield return null to wait for one frame to pass.

Also note that sayingf == true is a sin. This is your warning. The next infraction, I will resort to violence.

when using bool == true, either of these will happen: true == true which will become true. false == true which will become false. You can just write if (sayingf) as == true isn't doing anything to the bool.
