Description

Sets a new graphics quality level.

The list of quality levels can be found by going to Edit > Project Settings > Quality. You can add, remove or edit these.

    function OnGUI ()
    {
        var names = QualitySettings.names;
        GUILayout.BeginVertical ();
        for (var i = 0; i < names.Length; i++)
        {
            if (GUILayout.Button (names[i]))
                QualitySettings.SetQualityLevel (i, true);
        }
        GUILayout.EndVertical ();
    }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void OnGUI() { string[] names = QualitySettings.names; GUILayout.BeginVertical(); int i = 0; while (i < names.Length) { if (GUILayout.Button(names[i])) QualitySettings.SetQualityLevel(i, true); i++; } GUILayout.EndVertical(); } }

Note that changing the quality level can be an expensive operation if the new level has different anti-aliasing setting. It's fine to change the level when applying in-game quality options, but if you want to dynamically adjustquality level at runtime, pass false to applyExpensiveChanges so that expensive changes are not always applied.

When building a player quality levels that are not used for that platform are stripped. You should not expect a given quality setting to be at a given index. It's best to query the available quality settings and use the returned index.
