UNT0016 Unsafe way to get the method name

Using Invoke, InvokeRepeating, CancelInvoke, StartCoroutine or StopCoroutine with a first argument being a string literal is not type safe. Instead it's recommended to use the nameof operator or a direct call for coroutines. The further benefit of doing this is the ability for the method to use a rename refactoring without remembering to update the string literals.

Examples of patterns that are flagged by this analyzer

using UnityEngine;
using System.Collections;

class Camera : MonoBehaviour
{
    void Start()
    {
        Invoke("InvokeMe", 10.0f)
        StartCoroutine("MyCoroutine");
    }

    private void InvokeMe()
    {
        // ...
    }

    private IEnumerator MyCoroutine()
    {
        // ...
    }
}

Solution

Use nameof or direct call for coroutines.

using UnityEngine;
using System.Collections;

class Camera : MonoBehaviour
{
    void Start()
    {
        Invoke(nameof(InvokeMe), 10.0f)
        StartCoroutine(MyCoroutine());
    }

    private void InvokeMe()
    {
        // ...
    }

    private IEnumerator MyCoroutine()
    {
        // ...
    }
}
