public class PlayerAnimatorChecker : EditorWindow { // Required version private const string REQUIRED_VERSION = "0.99";

Here's a simple example of how this feature could be implemented in a Unity project:

using UnityEngine; using UnityEditor;

// Compare two version strings private static int CompareVersions(string v1, string v2) { string[] v1Parts = v1.Split('.'); string[] v2Parts = v2.Split('.');

// Compare with the required version if (CompareVersions(currentVersion, REQUIRED_VERSION) < 0) { // Show an update prompt EditorUtility.DisplayDialog("Update PlayerAnimator", "Please install PlayerAnimator version " + REQUIRED_VERSION + " or later.", "Update"); // Open the update URL Application.OpenURL("https://github.com/PlayerAnimator/PlayerAnimator/releases"); } else { // Show a success message EditorUtility.DisplayDialog("PlayerAnimator Version", "You have the required version of PlayerAnimator installed.", "OK"); } }

if (v1Part < v2Part) return -1; if (v1Part > v2Part) return 1; }

for (int i = 0; i < Mathf.Max(v1Parts.Length, v2Parts.Length); i++) { int v1Part = i < v1Parts.Length ? int.Parse(v1Parts[i]) : 0; int v2Part = i < v2Parts.Length ? int.Parse(v2Parts[i]) : 0;

[MenuItem("Tools/PlayerAnimator/Check Version")] public static void CheckVersion() { // Get the current version string currentVersion = PlayerPrefs.GetString("PlayerAnimatorVersion", "");

// Current version private string currentVersion;

return 0; } } This script creates a menu item "Tools/PlayerAnimator/Check Version" that checks the current version of PlayerAnimator and prompts the user to update if necessary.
