Question by Ortaz · Jul 06, 2018 at 10:26 AM · loadinghtmlloading screen

How to check is the game loaded in index.html?

How to check is the gameInstance in index.html is loaded? I have code:

 var gameInstance = UnityLoader.instantiate("gameContainer", "Build/webGLDom.json", {onProgress: UnityProgress});
 
 function SendToPlayer(func,what){
     gameInstance.SendMessage("SocialManager",func,what);
 }
 
 function handleVisibilityChange() {
     if (!document.visibilityState == "hidden") {
         SendToPlayer("OnGameVisible","true");
     }
 }
 document.addEventListener('visibilitychange', handleVisibilityChange, false);

But If I open another tab when the game is loading, I have an error. So I need to except such situation by adding code

 [if(gameinstance.MethodToGetIsTheGameLoaded())...][1]

is there such method?

1st solution : JS-side only

 var gameIsRunning = false ;
 
 
 var settings =
 {
     onProgress: UnityProgress,
     Module:
     {
         preRun: [ function() { console.log("About to run....") ; } ],
         postRun: [ function() { console.log("The game is running!") ; gameIsRunning = true ; } ],
     }
 };
 var gameInstance = UnityLoader.instantiate("gameContainer", "Build/webGLDom.json", settings ) ;

postRun may be called too soon. You may want the second solution


2nd solution : plugin JS + call function in Awake

 // gameStateController.jslib, in your Unity plugins
 mergeInto(LibraryManager.library,
 {
     OnGameStarted: function ()
     {
           window.gameIsRunning = true ;
     }
 }
 
 // GameStateController.cs, in your Unity scripts
 
 public class GameStateController : MonoBehaviour
 {
     [DllImport("__Internal")]
     private static extern void OnGameStarted();
 
     private void Awake()
     {
         OnGameStarted() ;
     }
 }

 // In your JS code

 window.gameIsRunning = false ;    
 
 var settings =
 {
     onProgress: UnityProgress
 };
 var gameInstance = UnityLoader.instantiate("gameContainer", "Build/webGLDom.json", settings ) ;

Sure :) Also It would be very good if you link me some guide how to create .jslib (I wrote my functions in index.html and use Application.ExternalCall() ). I saw that I have to create .jslib, I understand how to call functions by [DllImport("__Internal")] from C#, but don't understand, how to create .jslib file and associate it with my game, with code which is generated in index.html by Unity or with GameInstance and etc. So I need to understand the process of creating such a file and adding it to the project. Somehow can't find a guide on youtube.
