All the children of this "GameManager"-Object won't re-spawn when exit and entering Scene However, when I Exit Scene 1 and destroy some crates on Scene 2, return to Scene 1 and then return back to Scene 2 - the crates have re-spawned. How do I assign these crates to my "GameManager"? Isn't there a convenient script that is "hovering" over all scenes and I can just drop all prefabs to this script that should remain "Destroyed" after they have been destroyed once.? Collections. Generic. DontDestroyOnLoad transform. Destroy gameObject. RuneShiStormJan 8, Joined: Aug 3, Posts: 8, No, you'd have to write that yourself Joined: Jan 21, Posts: You can always have multiple scenes loaded at the same time. One scene could contain the crates, and one the main level. Load them at the same time. Then when you go to the other level, keep the crate scene loaded and set it as inactive. When you go back, just set it as active again. This way all changes in the crate level will remain.


Am not quiet sure what exactly is the issue in my code below. Am not able to save the game object with its component between the scene. I have created the singleton and dont destroy on load. Problem: Once I get back to the scene all the buttons and other components are not working at all. Is there any issue with my code? First your singleton getter and Awake function are kinda duplicating itself. Secondly what are the buttons? Its hard to tell without your full code i. Meanwhile I can tell you the problem I have once had, so I had a singleton in once scene that was having reference to buttons which were childs of the same prefab. Singleton declaration is persistent across the scenes, even if you don't use "don't destroy on load", singleton will keep all the references to the object and the variables as it was initialized. So I was initializing my singleton, than loading next stage, than coming back to first scene, and when I wanted to use the button I was getting an error "gameobject you want to use has been destroyed". The thing was, when reloading scene the buttons were "recreated" but the singleton kept references to the old initial gameobjects. So to solve it I just cleaned the Instance in OnDestroy method, and on start I create new Instance which will than load references to current buttons. Other solution for that would be to make the button GameObjects to prefabs. For me your code looks overly complicated. Since in Unity scripts are attached to gameobjects, I assume that you have somekind of empty 'controller' gameobject which you would like to preserve between scene loads. So, in your scripts awake-method call:. That's that. Because when you call inside Awake DontDestroyOnLoad thisthe this keyword actually points to your script. Well, it might be preserved but probably notbut anyway the 'hosting' gameobject is destroyed and new one is created after scene load. And when new gameobject is created it's Awake method get's called. And since it's new object all it's fields and members are set to default values. Meaning that all references are null. Let me break down the hierarchy, I should have explained it better in my question, anyways. I have a [empty]game object called gameManager. Added a audio listener component and the script to it. Basically the script contains the function for the button [controls audio on and off]. I used DontDestroyOnLoad ; But when the new scene is loaded everything get reset, So I thought probably singleton is the the one that I need to rely on.

When I press play on my level scene the first time, everything works perfectly, but when I go to the menu scene and then later return to the level scene. On the scripts shown in the picture below, for example, all but the references that were linked to prefabs in my assets were reset. I've tried assigning each and every variable with code instead of doing it manually, but even that doesn't work. This GameObject does have dontdestroyonload on. Why are these references getting reset specifically on this object? I don't have enough rep to comment, but did you save your scene after you added the references to the objects? I am unsure of how this fixed my issue, but it did. Load that scene only once. That's usually called a loading scene. You would never load that first scene again. If you want to load the scene again and you used DontDestroyOnLoad on one or more object, you have to destroy the objects manually. You can't prevent the objects from being created again since they are part of the scene. Usually al objects get destroyed automatically when you load a new scene, DontDestroyOnLoad prevents that. I am unsure of how this fixed my issue, but it did! Learn more. Object resetting after loading a scene for the second time in Unity [duplicate] Ask Question. Asked 3 years, 11 months ago.

Write powerful, clean and maintainable JavaScript. This tutorial assumes basic knowledge of Unity Engine. You will also find a download of the completed project at the end of this article. Unity is a game engine with its own philosophy. And by unique, I mean how easy it is to understand it. Supposedly, then you tried building a second level; say your first level was the interior of the house, and then your second level is outside of the house. The transition is using the door to load the next scene. You can edit the Scene using the graphical editor however you like. You can transition the scene using a single line of code that is triggered, perhaps, by the player touching the door, or using an object, etc. Each scene is built in its initial state. Transitioning the scene to another one means the new scene will be loaded at its initial state naturally. There IS a way to preserve game objects through scene transitions, effectively building not a scene-wide object, but a game-wide object, which will keep our data. What this flow does is ensure that scene 1 will always initialize the player with the starting data. This assumes you have placed the same Player object preferably a Prefabbed object into every scene. I am assuming that by this point, you do have two scenes, and an implementation for transitioning between them — refer to the starting project at the top of the article. First, go to your first scene, and create a new empty Game Object. Next, create a new C script preferably within a new folder — remember to keep things organized. Give it a fitting name. Attach the new empty C script to the new Game Object, and open the Script in your editor of choice. MonoDevelop, which comes with Unity, is good, but you can also use Visual Studio. The basic premise of the singleton design pattern is that there is one single public static instance of one class. This is a part of our solution to the problem of cross-scene persistence. This is what will keep the gameObject this script is attached to alive and carry it over to the other scene. The rest of the Singleton concept ensures that if there is another copy of the object with this same script attached and there will be, you need to put this object into every scenethen the other object will be destroyed and this one original will be saved. If you wish, you can test this now. Put the GameMaster or GlobalObject or whatever is carrying this script into every scene you have, and try to transition the scenes at run-time.

Surprisingly, complex scene management scripts are not required for implementing any of this functionality. Additive scenes are also very adaptive and can be used to load multiple game scenes, configuration scenes, debugging scenes, and many other useful alternatives. I originally investigated scene management in Unity to see how well it would handle loading of scenes in real-time, as the player explored the game world. I hope this post gives you a useful introduction to the scene manager and how to use its most basic functionalities. Here at Myriad Games Studio, we do a lot of game jams. The internal jams are generally focused on making a game that implements some functionality we want to learn more about. The TasJam events are where we flex our design muscles and try to make an interesting game within specific constraints. Games jams really help us to see in what areas we need to gain more knowledge. After discussing with the team, I set aside a couple of weeks to research and implement a scene loading solution. The resulting scripts are simple and easy to add to any new game we make. Every game jam now has a ton of saved time as we have a flexible scene setup and a pre-made scene loading solution. This means we can spend more time in the design phase — the hardest part of game development! To achieve a working prototype using the scene manager, we need to do the following:. This will result in scenes that can be loaded in any order, with simple and easy calls to the SceneLoader class to load a scene or scenes. The setup of the scenes is very simple. We need 3 scenes with a similar format to the following. Note: you can drag and drop your scenes into the scene hierarchy, and display multiple scenes at once! In older versions of Unity, any scene management was done using the Application class, which contains a hodgepodge of generic static methods. Thankfully Unity has solidified the Scene-related methods into their own namespace — UnityEngine. This namespace contains most of the useful methods for loading and unloading scenes. Note: all scene-related methods in the Application class are now deprecated. The SceneManager contains methods for loading scenes synchronously and asynchronously, so if we go to some extra effort, we can have scenes loading in the background without having the game hang or freeze. This was done for a number of reasons; firstly, singletons lend themselves to manager-type classes, as you generally only want one instance. Secondly, the singleton implementation I use ensures that the game object is never destroyed when a scene is unloaded. Finally, the MonoBehaviour inheritance allows the singleton to have access to inherited methods such as Awake, Start and Update.

Halfway trough the process it says unable to load game. Anyone had this problem and figured it out? Showing 1 - 12 of 12 comments. What happened the last time you saved? Was it interrupted in any way? Did you shut down immediately afterwards or enter sleep or hibernation mode whilst the game was still open? Do you have any backup save games? Do these load? Do you have any kind of anti-virus? If so, what type? It was not interrupted in any way. Saved and took a break for a few hours, and when I tried to load it wouldn't. No back up saves and no anti virus up and running. Tried to clear cache also. Okay I'd suggest using the auto save option 'new file for each save' and have it set to weekly in case this happens again you'll have a recent backup. If you get too many save files you can manually go into the folder and remove some of the older ones. Let us know if they all save and load without issue. So the save I started with is broken? Such a shame, it was starting to get exiting. Hercules View Profile View Posts. My games stopped loading today, started a new save new team and that save won't load, and also tried a cloud save from 3 weeks ago Nothing will load. I can start a new game, but not load any saves. Also reinstalled the game, verified the files, and nothing is helping. I have had the same problem that my game wont load. I was wondering if there has been any ways to fix this that have come up a few months on? View Profile View Posts. Same things happening to me my save has dissapeared and i have a back up and it wont load also im trying to start again its not letting me save making me wna give up on the game. Same as I experienced today, and also I experienced a crash. First time ever in FM!

So I created a music player to play music through all my menu and story scenes without interrupting, but then in my game scene I want to delete that music. How can destroy the playing music when my game scene loads? I created a script called Destroyer. Then in that script I added this code, and it doesn't play anymore. You can destroy the object by calling Destroy objectname directy like mentioned above by Almo. You could place it in the same function call which is responsible for the change to the scene where you don't want the music to be playing. I had the same issue so I tried Destroy gameObject ; as mentioned in answers above but It didn't work for me. So I tried SceneManager. Additive ; and it worked for me. Read official docs here.

Game Development Stack Exchange is a question and answer site for professional and independent game developers. It only takes a minute to sign up. I figured out how to make certain objects like my Camera and Canvas persist across scenes, but I can't figure out how to access them in the editor from scenes in which they're not instantiated. I can make these objects prefabs and make my changes to the prefab rather than the instance, but then I can't make references in the prefab to objects in the hierarchy; I would have to use an instance of a prefab to do that. How can I edit subsequent scenes in the same way that I edited the first scene, where all the DontDestroyOnLoad objects are instantiated for the first time and I can access them through the hierarchy? A scene is basically a collection of objects and serialized properties that the engine bundles and can load together. As such, it's allowed to cross reference objects that belong to the same scene. DontDestroyOnLoad mark an object in such a way that when a non additive scene loading operation Apllication. LoadLevel LoadLevelAsync is performed, that object won't be destroyed. It controls the runtime lifetime of an object. In editor mode, isn't possible to reference an object across different scenes. That's how it works, right. If you want to setup references in one of your persistent object you basically have 2 ways:. The object instance is only available when a particular scene will be loaded at runtime or in the editor for editing. Try using the new SceneManagerAdditiveLoading function. You can view a tutorial at YouTube. Use GameObject. Find in Scene two to find the relevant objects in scene one, and assign them to your scripts.

Fleshing this out to a complete example without relying on an external video would make this answer even better. It also has a script that does a load for scene two.

Solution two Create a singleton manager, which will avoid the sometimes expensive GameObject. Find "object name that won't be destroyed" ; You will get an object reference in each scene.

Do not destroy the target Object when loading a new Scene. The load of a new Scene destroys all current Scene objects. Call Object. DontDestroyOnLoad to preserve an Object during level loading. DontDestroyOnLoad does not return a value. The following example script uses Object. The example has scene1 which starts playing background music from an AudioSource. The music continues when scene2 loads. Switch between scenes using a button. To implement this example, create two new Scene s, named scene1 and scene2. Open scene1 and add the SceneSwap. Next, add DontDestroy. Create a tag, call it musicand add it to BackgroundMusic. Switch to scene2. Again add SceneSwap. Save the Project. Return to scene1 and run the Project from the Editor.
