  • Hi Guys, i'm spending a lot of time in searching how to get js data from the external js file, but no luck.

    I have added *.js file to the project folder, and i need to pick a function from this file.

    So, if this function or value inside of it is true(or exist), i'm switching my value inside a Construct and executing new js

    Is anybody know how to do that? Or maybe you can point me to the existing tutorials that i missed.

    Many thanks!

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads

  • Ideally you'd use the plugin sdk to access javascript.

    But you can use the Browser object with it's exec js action to run some javascript.

    You can load a js file in your project folder as if it was included in your html file by executing this:

    "var js = document.createElement('script');
js.type = 'text/javascript'; 
js.src = 'chipmunk.js';
document.body.appendChild(js);"[/code:300sntdv]
The library takes time to load though, so you can't use it immediately.

Another option is to load the the file into a variable with the ajax plugin.  Then you can use exec js with that.

  • Thanks for the answer!

    I found an and easy way how to do that:

    To hear from the index.html file i put some code to it.

    i need index.html file to read from the linked js file in the game folder

    We have to know ads availability to make an action in construct .

    That code was pasted to the end of the index.html file.

    Inside the bottom <script></script> brackets

    function checkForAd()
{
 //make sure webstorage is supported
 if (typeof (Storage) !== "undefined")
 {
  	//check if the key exists
  	if (//type your funtion from any of the js files you have in your project) {
  		console.log("Ad is available; localforage is " + localforage);
  	 	localforage.setItem("adAvailable", "yes", function(){
  	 		console.log("item has set to: yes");
  	 	});
  	}
  	else {
  		console.log("Ad is NOT available; localforage is " + localforage);
   		localforage.setItem("adAvailable", "no", function(){
   			console.log("item has set to: no");
   		});

 	}

 	console.log("localforage.adAvailable=" + localforage.getItem("adAvailable"));
 } else {
 	console.log("Storage is undefined");
 }

}

[/code:1udlmti1]

In the construct i made some actions:

Every level i need to call this script to not left it sleep ( just to be sure it works), by Executing javascript: "checkForAd();"
Each time we loose the game we checks the availability of the local storage key : LocalStorage- check item exist: "adAvailable"
On iten "adAvailable"  exist we are getting it: LocalStorage get item: "adAvailable"
And then, on item Get, we can compare it's key  or just do our action we plan, for me it to create a button.

So, i hope it can help you to hear from the html file or js file any function you need.

Peace!
