[Plugin] JavaScript (C2 and C3)

It doesn't work:

Sample Javascript file:

var global_variable = "Global Variable's value.";

function global_variable_function()

{

console.log("global variable function called");

}

var global_object = new class_object();

class class_object

{

constructor()

{

this.name = "Kenny";

this.age = 23;

}

internal_class_function()

{

console.log("Internal class function called.");

}

}

With that sample javascript file, I tried Browser Log:

JS.JSCodeValue("global_variable")

and I got:

ValerypopoffJS plugin: Error in 'JSCodeValue' expression

---------------------

JS code: global_variable

---------------------

global_variable is not defined

Then I tried Browser Log:

JS.Value("global_variable")

And there is no error...instead...I got....0 !

Toddler Well it's weird. I just tested it with javascript you provided and it works fine in both C3 and C2. Can you give me the project file that reproduces the problem?

Yep. You just didn't add the name of the script to "Script files" property of the plugin. You only added the script file to the project and the plugin has no way of knowing that. Your javascript is simply not added to the page. So the plugin says the truth: "global_variable is not defined" and other error messages.

When you add the name of the script properly, everything works fine.

Here is the file:

To access Javascript Variable:

JS.Value("global_variable")

JS.JSCodeValue("global_variable")

Both does the same thing, so...why ?

Priviet Valery!

I am making a simple GUI project with C2 running in nw.js (I am not a programmer so C2 was the choice), the problem is that i got stuck when I need to encrypt a string (need aes encryption):

I am over a month trying it through all plugins I found for call javascript or other means, getting mad, although I read all, and tried all can simply not do it...

I wonder if you could help me to get out of this problem: I need an example of capx file that could pass a string (text to encode/decode) and a password and take the result back in C2.

the javascript I am trying to run would be something like this (in my leak of knowledge of programing was the best I could find and modify to be working in nw.js):

-------------------------------------------------------------------------------------------

function encrypt(text,parol,aes_format){

// covert to string to be used in Cipher

var aes_format = "" + aes_format

var parol = "" + parol

var cipher = crypto.createCipher(aes_format,parol)

var crypted = cipher.update(text,'utf8','hex')

crypted += cipher.final('hex');

return crypted;

return pass;

}

function decrypt(text,parol,aes_format){

// covert to string to be used in Decipher

var aes_format = "" + aes_format

var parol = "" + parol

var decipher = crypto.createDecipher(aes_format,parol)

var dec = decipher.update(text,'hex','utf8')

dec += decipher.final('utf8');

return dec;

}

// example variables

var hw = "hello world"

var hw2= "5876e13e22e45d9cc1397e0ac0658bf0"

var parol = "e7wn/S4wJ2&·ns%e7wn/S43J@3Uns%e7wn/¨92J28Uns%e7+n/S()J28U"

var aes_format = "aes-256-cbc"

// example call functions encrypt & decrypt

encrypt(hw,parol,"aes-256-cbc")

// decrypt(hw2,parol,"aes-256-cbc")

--------------------------------------------------------------------------------------------

and I really need to survive achieve in C2: call js to "encrypt(text, pass, format) and same for decrypt function" and receive results back in any variable of C2

could you help me?

thanks in advance

sorry, at encrypt function this line have to be removed

return pass;

thanks!!

hugone I'd suggest you ask around in the Construct Discord community. People discuss stuff like that all day long there: discord.gg/HnuhDR

Sposivo Valery I will!

valerypopoff, do you think there is a way to say for example, create a class on the *.js side and then make every instance of a sprite have an instance of that class ?

Think of it as polymorphism, your "extends" so to speak.
