I have already a backend storing other information for each player. To use backend to have IDs of the players to connect with FB ID's is the worst thing you could do. The simplest thing would be to have data from connected players that include ID, name, photo etc.. The only thing missing is "scores" that is implemented from facebook SDK v6.2

API Reference v6.2 Changelog

Connected Player Score Entries Introduces the new Leaderboard.getConnectedPlayerEntriesAsync() API, which fetches the score entries of the current player's connected players from the leaderboard.

I am still wondering why Scirra has not given any answers regarding Facebook Instant Games plugin, which is supposed to cover this function since it implements version 6.2 of SDK.

That functionality exist in Load Leader board data, just change Results into Connected players.

No, this i snot the problem. The problem relies on Facebook plugin implementation, although it is supposed to use SDK version that includes those features.

What i need is having:

Player name

Player Score

Player Photo

Player ID

The whole issue is that there is data for Player name, Player Score, Player Photo on "leader board" and there is Player name, Player Photo, Player ID on "connected players".

How can we fetch all data? Or how is it even possible to correlate both of them?

I can take a look at your project if you don't want to share it here, maybe I'll see something that you missed. My email is doperst2006 (at) gmail.com

I have sent you the project sample. You can find those event on "playStage" event sheet

Spooky becomes more spooky....

After putting an alert to show "token.count" and after a "wait 1.0 second" (because without this, the count is 0 although its on another event + event level) I have noticed this:

If I put a single alert, it shows "9" (which is correct as I have 9 tokens created)

If I put 2 alerts, the first one shows 0 and the second one shows 9!

If I put N alerts, then guess what? It shows 0 until the last which shows 9!!!

Its like the count of the objects only takes place on the last alert. Even if you put another condition or even wait in between, then the tokens.count only works for the last event.

I am starting to believe that there is a completely messy code under the hood regarding instance picking/counting etc. Which obviously is more than frustrating because this is a game engine. Game engine supposed to have 1 thing super clear and solid.... object access...!

I had the same without "pick all". The group only gets deactivated by one line at the end of this group. I have put a log message and it works. But with browser alert "tokens.count" I only get "0". I cant reproduce it because it doesn't happened on the rest of the project. This is extremely frustrating and awkward bug...

AllaR this is a very nice solution. I tried to implement with line slope equation (calculating the next point of x using y and vice versa according to start point and end point positions). The result was a mesh, as y or x get extreme values according to the slope of the line.

You solution is much better. I will also put some "clamp" to put some boundaries of drag paths.

I wasn't very clear on my description. I want to achieve this on diagonal lines. I can use the two point line-slope formula but the difficult part is if you have multiple points A -> B -> C and you want the sprite to follow the path created from these 3 parts. I cant even image how harder it must get when you want to implement this with bezier curvers.

I am trying to implement a specific type of control where the user can drag an object but that object will move only over a certain path.

At first it would be great if at least I could implement it using only linear path (just simple line between two points). I want the drag operation to take X,Y of drag and apply the movement to the relevant path. Think of it as a slider.

I tried to use timeline (with steps) taking advantage of X,Y position but it doesnt work for me (also it seems to be a non-pretty and clunky solution).

Any ideas?
