Here's a test program: https://www.newgrounds.com/projects/games/6333685/preview


All APIs work except for "CloudSave.setData" because it performs a POST. The JS console shows the CORS errors.

To address that, the fix needs to be on the server. Something like this on the header:


Access-Control-Allow-Origin: https://uploads.ungrounded.net

Seems using xhr or fetch doesn't make much difference. I think the Access-Control-Allow-Origin needs to be set on the response header from newgrounds.io

I think we could use the CloudSave.setData method to save games on Newgrounds, but currently that call is blocked by CORS policy. I think it could work if the "uploads.ungrounded.net' domain was allowlisted.

This is the error I got when trying:

Access to fetch at 'https://newgrounds.io/gateway_v3.php' from origin 'https://uploads.ungrounded.net' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains the invalid value 'none'. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

fetch is very iffy. you are better off using xhr

90% of the time if you get a CORS error in the API, it's probably our server dumping an error page (vs a proper API response) because something was used incorrectly.


I was looking at our error logs and noticed a bunch of cloudsave calls that were not sending a string value, but rather a JSON object. Upon further investigation, I wasn't handling improper data types correct, so instead of getting a helpful API response, you would be getting a generic NG error page, which wouldn't render any CORS headers.


I got that fixed so you're likely seeing proper error responses now. You'll just need to serialize the data you want to save to a string before you post it. You can use whatever string format you want.

Thank you for fixing that! I'm able to use the API to save data now.

I'm hesitant to admit how in over my head i am but how does the api interface with game maker studio 2?

I made a game using 95% game maker drag and drop, and decide to put it on here for others to see.

Now i want to add some medals, just some little goofy ones , but i can't figure out the very basics of it.

Currently i just have this script triggered at the start of the game. it's not even compiling without error. what would the appropriate form of this be?


ng_connect(5...9:O...8, M...==);

ng_initialize_medals_and_scoreboard()

ng_request_login()

ng_unlockmedal(Is This Thing On?)

Hello,


I'm trying to make a App.checkSession on my NodeJS local server and apparently the json is working when I use the https://www.newgrounds.io/help/communicating-with-the-server/ form, but when I try doing a POST request on my server, a curl or postman, it keeps returning "message": "Missing required request", "code": 100. Am I missing something?


Body Json. No Params. No Header. No Auth.

Got it, just in case someone needs to fix this, it's because if needs headers 'Content-Type': 'application/x-www-form-urlencoded'. Leaving a little code just in case someone was looking for this solution.


...

const NEWGROUNDS_API_URL = 'https://www.newgrounds.io/gateway_v3.php';
const APP_ID = 'XXXXX:XXXXX';

const { session_id: SESSION_ID } = req.body;

const requestData = {
   app_id: APP_ID,
   session_id: SESSION_ID,
   debug: false,
   execute: {
    component: 'App.checkSession'
   }
  };

	const requestBody = {
		request: JSON.stringify(requestData)
	};

  console.log('POST:', requestBody);

  axios.post(NEWGROUNDS_API_URL, requestBody, {
		headers: {
			'Content-Type': 'application/x-www-form-urlencoded'
		}
	}).then(response => {
    const data = response.data;
 
    console.log(data);
	console.log(data.result);
	console.log(data.result.data);
	console.log(data.result.data.session);

...

})
   .catch(error => {
    console.error('Error:', error);
    res.status(500).json({ error: 'Error' });
   });

I remember there being anti-spam features, so I'm wondering how reasonable auto-saves are when a particular user might be triggering 30 per minute or so for a few minutes. It wouldn't be a lot for me to restrict it to a few times per minute, just wondering how necessary.

Every 2 seconds sounds unnecessarily excessive. I’d caution against it even if it didn’t trigger our DDos protection at the user level, it could flag the app ID as being spam if your player base gets big.

hey, im making a longer style game where players may go hours in between earning medals. Ive found in playtesting that after a while the session times out and you can no longer earn medals. Medals in the game are saved locally and re-awarded when booting up the game, so its not the worst thing ever, but I imagine a handful of people might miss this so i wanna squish the issue if I can. It seems like its a known issue, I've found people discussing it years back on the broken medals thread, but can't seem to find a real fix.

im using 3p0ch's godot 4 ngio script to handle everything. their script does Gatway.ping every 5 minutes to keep the session from timing out, but it doesn't seem to work, even when lowering the timer. If yall know a solution that would be very much appreciated, thank u

also possible this issue only occurs on the preview version and im just unaware of that, if so sorry lol

check out my games !

There seems to be an issue with the ping command – the session apparently times out even if you keep pinging. It's not just you, and it's not due to incorrect use. PsychoGoldfish is aware of it; see the discussion here.

thanks for letting me know, glad its gettin worked on. for the time being, is there a way around this? My game has a generic "open the game" medal, i was thinking maybe trying to award that medal every 5 minutes or so could potentially work, but waiting around for an hour to test that is pretty annoying lol

Yep, the workaround is just what you're doing - to have your game save data on which medals should be unlocked since you can still save data locally even if the session times out, and make the game send API calls to unlock all of the medals whenever the player loads the game's page. Since people are kind of used to not having medals show up as being earned immediately anyway, there probably won't by many people who notice or mind. Unlocking a medal every 5 minutes probably won't work - we've tried sending commands other than ping (specifically App.checkSession), to no avail.

The session issue has finally been fixed, so as long as you're passing a session with the ping command the session shouldn't expire during gameplay anymore
