Came here to see an effective way to make the buttons actually load levels. Perhaps make a part 2? as it stands now, a strong tutorial for laying out a bunch of buttons, but not very useful if you don't demonstrate how to actually wire them to functions.

Amazing tutorial ! I was wondering if it was possible to use a button in order to swipe to a certain page; like an Option button that when you press it, it swipes directly to a certain panel (currentPage)? Thank you so much for your great tutorials :D

@bene5776 4 года назад

I‘ve got a problem! With any new Panel/Page i is reset to 1. So I‘ve got 40 Levels on 2 pages: on the 1. Page are levels 1-20 and on the 2. page should be levels 21-40 but there are also the levels 1-20 because i is reset to 1... Do you have any solution for that? Thanks for the tutorial and your reply.

@pressstart6864 4 года назад

If you use the code in the video, it should solve your problem. At 15:40 the numbers increment for each page.

@uhrgmreghagemge7419 5 лет назад

Hello, I'm not sure why It doesn't work for me. I copy pasted the code, created everything like you did even the button size, image size. The problem seems to be that the script doesn't take into account the image dimension , only the button When I print the iconDimensions = levelIcon.GetComponent().rect; It prints the button dimension and not the image, you said that the script will caculate the dimension based on the icon am I missing something ? Thanks for your help That is how it looks like : imgur.com/a/X2C5yip

@hollowbloop3662 4 года назад

"panel.transform.SetParent(thisCanvas.transform,false);" is the line thats casuing your issues. Unfortunately do not know how to fix it

@hollowbloop3662 4 года назад

Do not make the 'levelHolder' GameObject use a prefab but rather let it be the normal gameObject from the Scene. This fixed the problem for me. Hope this helps.

@TheTylerBlair 4 года назад

Check to see if you scaled the Icon prefab. Change the width and height attributes and reset the x and y scale back to 1.

@ei05056 3 года назад

I don't get it, you had already added the GridLayoutGroup to the Panel in the Unity Editor, why do you need to do it again in the code?

@TomerGamerTV 2 года назад

and how do I make it clickable?

@krishshah8306 5 лет назад

How could you make it so that each icon, when clicked, would go to its associated level because you cannot add a script to a game object that doesn't exist until you start it.

@pressstart6864 5 лет назад

You can add a script to the icon before you make it a prefab or you can use addcomponent to add it during runtime.

@punchspelledbackwards 3 года назад

using UnityEngine; using UnityEngine.SceneManagement; public class Script : MonoBehaviour { void SelectLevel(string scene) { SceneManager.LoadScene(scene); } } you can also load scenes by making a string variable then just loading it, like so: using UnityEngine; using UnityEngine.SceneManagement; public class Script : MonoBehaviour { public string levelToLoad; void SelectLevel(string scene) { SceneManager.LoadScene(levelToLoad); } } or you could do it with build indexes: using UnityEngine; using UnityEngine.SceneManagement; public class Script : MonoBehaviour { void SelectLevel() { SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1); } } this is for if you want to load the next scene bte ^^

i have a question i get this error do you now how i can fix this Object reference not set to an instance of an object and i get this as a messege Can't add 'GridLayoutGroup' to Page-1 because a 'GridLayoutGroup' is already added to the game object! A GameObject can only contain one 'LayoutGroup' component.

@computercrafty9090 3 года назад

remove the grid layout group from the panel(the same panel that has the level buttons). The code itself will add it so you dont had too. Had the same error tho. Welcome :)

@NajeksYoutube 4 года назад

Everything is good but I think you forgot about " how to make buttons working". How to attach an onClick function to them.

@aferg8587 4 года назад

Did you figure it out? I cant figure out how to make each button take me to a unique scene

@Zombivoro 4 года назад

@Bendegúz Anisics Thanks, without this comment the tutorial is pointless. Although, I don't think it's a great solution. The Level Selector script should had been made with this in mind so you don't need to get the level number from the button text number, which I would say it's a pretty bad practice.

@chinyereajala9886 3 года назад

@Bendegúz Anisics Hey any idea on how to lock and unlock the scenes as you play through the level
