Empty array if strings in c# for unity game-CodePudding

I am trying to empty and array of strings every-time a user clicks on load profiles so that the array doesn't get over populated with the same profiles over and over again every time they click load.

This is my array:

string[] files;

This is how i get the profiles but i need to empty it whenever getProfiles is called so it doesn't over populate with duplicate profiles

private void GetProfiles()
{
    //Check if directory with saved profiles exists
    if (Directory.Exists(filePath))
    {
        //Clear files array


        //Get all of the file paths of each file in this directory
        files = Directory.GetFiles(filePath);
        //profileTileTemplate.SetActive(true);

        //Go through each file and read the data and create a profile for each json file
        for(int i = 1; i <= files.Length -1; i  )
        {
            string json = File.ReadAllText(files[i]);
            Profile savedProfile = JsonUtility.FromJson<Profile>(json);
            Instantiate(profileTileTemplate,LoadProfileTransform);
            profileTileTemplate.SetActive(true);
            profileTileTemplate.GetComponentInChildren<Text>().text = savedProfile.playerName;
            Debug.Log(savedProfile.playerName);
        }
    }
}

how do i clear this array?

I have tried setting it to null but it doesn't work.

CodePudding user response：

Question is not clear, but if you want to empty the array and stay with the same length then you can write this wherever you want to.

files = new string[files.Length];

CodePudding user response：

as said I don't think this is related to the array at all .. GetFiles everytime returns a new array there are no duplicates.

However, you Instantiate a bunch of objects into the scene and never destroy them!

You could do this first

foreach(Transform child in LoadProfileTransform)
{
    Destroy (child.gameObject);
}
