Create LEVEL MENU in Unity: UI Design & Level Locking/Unlocking System! 

Hi 🖐 - I agree with your opinion. Using a single background is ideal for both practicality and size optimization. - I created one button in Adobe Illustrator and gave them different numbers, then export. - But in real game it makes sense to do as you say (if all buttons will be in the same design) Thank you so much for your nice comment 🙏😊

Hi, public void ResetGame() { PlayerPrefs.DeleteAll(); } Connect this method any button as click event. And thanks for your nice feedback :)

Thank you loads, you are awesome!! @@RehopeGames

@@salmadiaaelabsi You're welcome. Thank you very much for your courtesy.😊

You find the solution???

Coming soon ...

Hi , did you follow me step by step. Can you show me your script ?

using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI; public class levelMenu : MonoBehaviour { public Button[] buttons; public GameObject levelButtons; private void Awake() { ButtonsToArray(); int unLockedlevel = PlayerPrefs.GetInt("UnLockedLevel", 1); for (int i = 0; i < buttons.Length; i++) { buttons[i].interactable = false; } for (int i = 0;i < unLockedlevel; i++) { buttons[i].interactable = true; } } public void OpenLevel(int levelId) { string levelName = "Level " + levelId; SceneManager.LoadScene(levelName); } void ButtonsToArray() { int childCount = levelButtons.transform.childCount; buttons = new Button[childCount]; for (int i = 0; i < childCount; i++) { buttons[i] = levelButtons.transform.GetChild(i).gameObject.GetComponent(); } } } ................................................................................. using UnityEngine; using UnityEngine.SceneManagement; public class FinishPoint : MonoBehaviour { public GameObject levelCompleted; private void OnTriggerEnter2D(Collider2D collision) { if (collision.CompareTag("Player")) { UnLockNewLevel(); SceneController.instance.NextLevel(); levelCompleted.SetActive(true); } } void UnLockNewLevel() { if (SceneManager.GetActiveScene().buildIndex >= PlayerPrefs.GetInt("ReachedIndex")) { PlayerPrefs.SetInt("ReachedIndex", SceneManager.GetActiveScene().buildIndex + 1); PlayerPrefs.SetInt("UnLockedLevel", PlayerPrefs.GetInt("UnLockedLevel", 1) + 1); PlayerPrefs.Save(); } } }@@RehopeGames

i ifollwed you step by step but check my code if there is something wrong and thank you for your help @@RehopeGames

Hey did u check my code @@RehopeGames

hey can you check my code plz@@RehopeGames

Thank you so much bro 😊

Look in the script, you have a "1" somewhere

Hello , you can do it using New Input System

Did you drag and drop the level buttons to the Button slots (Button[] array variable) on Unity ?

Were all the levels unlocked when you first made them, or are they all unlocked after you complete the levels?

@@RehopeGames they are unlocked all the time 😔 before and after I play the game

I am also experiencing this issue. Triple checked the scripts and everything in editor and can’t find where the break is…

Hello, Of course it's possible bro 😉

Hello, You can Delete the PlayerPrefs Data ( Contain Level Progress) to Reset the game. Thanks 🙏

I'm so glad! 😊

🤦‍♂️

Nice 👍

You should create a SceneController script. I've created it in this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E25JWfeCFPA.html

İşine yaramasına sevindim, güzel geri bildirimin için teşekkürler kardeşim parmaklarına sağlık 😊

@@RehopeGames evet çünkü oyun projesi için bir video yapmamız gerekiyor

😅

Hello , Did you add all scenes to the Build Settings panel? Check the scene name (You called as Parameter)

@@RehopeGames , Unity Unite... Unity code.

I've noted your request . Thanks for your feedback 😊🙏

@@RehopeGames OMG

I've noted your request thanks 🙏

Thank you so much ❤🙏

void Update() { if(Input.GetKeyDown(KeyCode.M)) { PlayerPrefs.DeleteAll(); Debug.Log("PlayerPrefs Deleted"); } }

Hello, I'm gonna publish all project to itch.io in this week and I will share download link

⁠@@RehopeGamesHello can i have the download link 🥹

Thanks! 🙏😊

Hello, I hope you solved the problem. If not , Check the Rect size of the buttons. Thanks 🙏

I am facing some issue with a restart button. Like the advices you gave to one of this comment. If you could make a short video about it. It would be fantastic. 😋

Thanks 😊

Hello! Yes, you can do this with a simple algorithm. First, you set the required high score for each level. Then, each time the player's score changes, you check whether they have surpassed the required high score for the current level, using a conditional statement. If they have exceeded the required high score, you call the necessary function to unlock the next level.

@@RehopeGames thank you so much! would it be possible if you could give me some example simple code I could use to start off? Sorry, I am quite new to coding haha

and i also cant drag n drop or references the object level from levels panel on inspector

Did you follow me step by step?

I have the same issue. @@RehopeGames This is my code using UnityEngine; using System.Collections; using System.Collections.Generic; using UnityEngine.SceneManagement; using UnityEngine.UI; public class LevelMenu : MonoBehaviour { public Button[] buttons; public void Awake() { int unlockedLevel = PlayerPrefs.GetInt("Unlockedlevel", 1); for (int i = 0; i < buttons.Length; i++) { buttons[i].enabled = false; } for (int i = 0; i < unlockedLevel; i++) { buttons[i].enabled = true; } } public void OpenLevel(int levelId) { string levelName = "Level " + levelId; SceneManager.LoadScene(levelName); } }

Hi , can you show me your script?

@@RehopeGames using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI; public class LevelMenu : MonoBehaviour { public Button[] buttons; private void Awake() { int unlockedLevel = PlayerPrefs.GetInt("UnlockedLevel",1); for (int i =0; i < buttons.Length; i++) { buttons[i].interactable = false; } for (int i =0; i < unlockedLevel; i++) { buttons[i].interactable = true; } } public void OpenLevel(int levelId) { string levelName = "Level" + levelId; SceneManager.LoadScene(levelName); } }

Thanks 🙏

I glad to hear that , thank you so much bro 😊

Yes of course, İf you will keep the progress data in local ( client side ) you can store the data as json file. (don't forget to encrypt the json file ) Create Default Player Data and change the Player Data when you wanna reset the game. This topic is actually detally, maybe I can share a video about that.

the Next Level, complete Unity reg

@@RehopeGames just started doing the tutorial, after finishing i noticed that progressing does not work! ive tried removing some non-level scenes but it still doesnt work :(

Thank you so much bro for your nice feedback 😊

Check the your script

I will check, thanx

Thanks ✌

You probably forgot to add the game scenes to the build settings panel.

I got it working thanks tho

@@angrypuppy 👍

Thanks 😊

I'm glad the video helped you 😊 Thanks for nice feedback 🙏

Hi, I hope you solved it. If not can you show me your script

had the same issue. Dont use PlayerPrefs.GetInt("UnlockedLevel1", 1); instead use PlayerPrefs.GetInt("Unlockedlevel", 1); and dont put level 1 as part of the buttons in the levels panel

Hello , if you run this code All level progress will reset. PlayerPrefs.DeleteAll();

@@RehopeGames Thanks

@@RehopeGames Hi, i made a button "delete progress", added the DeleteProgress() function to the script with PlayerPrefs.DeleteAll(); but it does not lock the levels again when i click the button, any idea why and how to fix that? Also, big thanks for this video, great help!

ok I added PlayerPrefs.Save() to the Awake and now the button resets the progress but only when I play again, the buttons are still unlocked when i cycle through scenes and main menu

Did you follow me step by step ?

@@RehopeGamesi didt see the other videos only this, and i followed this video step by step

I gave the project the name 2D Platformer

Yes of course 😉

I'm glad hear that. Thanks 😊

😂 Hi! I'm gonna share all project soon.

You wanna reset the game progress when exit the game ?

yes@@RehopeGames

my level selection is not working now after i did no open the project in a week @@RehopeGames

how could i reset the unlocked level? @@RehopeGames

@@RehopeGames please help me my other levels doesnt unlock even i reach the finish point i check the codes and are all the same but its still doesnt work please help this is the code in my finishpoint using UnityEngine; using UnityEngine.SceneManagement; public class Finish : MonoBehaviour { private void OnTriggerEnter2D(Collider2D collision) { if (collision.tag == "Player") { UnlockNewLevel(); GameManager.MyInstance.Finish(); } } private void OnTriggerExit2D(Collider2D collision) { if (collision.tag == "Player") { UIManager1.MyInstance.HideVictoryCondition(); } } void UnlockNewLevel() { if(SceneManager.GetActiveScene().buildIndex >= PlayerPrefs.GetInt("ReachedIndex")) { PlayerPrefs.SetInt("ReachedIndex", SceneManager.GetActiveScene().buildIndex + 1); PlayerPrefs.SetInt("UnlockedLevel", PlayerPrefs.GetInt("UnlockedLevel", 1) + 1); PlayerPrefs.Save(); } } } this is the code in my Level Menu using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI; public class LevelMenu : MonoBehaviour { public Button[] buttons; public GameObject back; private void Awake() { int unlockedlevel = PlayerPrefs.GetInt("Unlockedlevel", 1); for(int i = 0; i < buttons.Length; i++) { buttons[i].interactable = false; } for(int i = 0; i < unlockedlevel; i++) { buttons[i].interactable = true; } } public void Earth() { SceneManager.LoadScene("EarthScene"); } public void Fire() { SceneManager.LoadScene("FireScene"); } public void Water() { SceneManager.LoadScene("WaterScene"); } public void Air() { SceneManager.LoadScene("EarthScene"); } public void Backbutton() { back.SetActive(false); } }

also is there a way i could reset the levels with I link it to a "new game" button in the home screen?

Did you create scene manager script ?

Yes you can reset using PlayerPrefs.DeleteKey(string key)
