  • Having the error too.

  • When it comes to using Sync variables, its one directional only, host->clients.

    There's two ways that data comes from the clients:

    • Inputs (see the multiplayer tutorials)
    • Messages

  • Can you attach a CapX?

  • Ashley

    Thanks for the reply. I think maybe I was unclear on the PeerID's thing as I am not talking about assigning PeerID's to Peer objects, but rather to "bombs" that were placed by specific PeerID's which are created on the host and sync'd via Sync Object (position, low nearly static). I'll go ahead and use my workaround for dealing with the related UID issue though. The point was just to show why I have use for syncing non-numerical instance variables

    On the variable sync'd event, I figured you had some function that knew when it was updating a variable as the result of a multiplayer sync rather than just a variable change itself, which seemed like it would be lower overhead than polling. I'll just poll as long as that's decently efficient.

    Thanks again for such an awesome feature!

  • The broadcast message is broadcasted as a string (Not a Number ). Try assigning it with int(Multiplayer.message).

  • While I appreciate your reply, I think you misunderstood some aspects and your patronizing tone is less than helpful.

    [quote:2vngnzy1]* You can get a Room list already.

    Where? I see actions and values for INSTANCE lists, but nothing regarding rooms. If i've missed an available action I would love a pointer in the right direction on that as there isn't a manual entry yet and I see no mention of it in the 3 tutorials provided...

    [quote:2vngnzy1]* PeerID are synced between player connections.

    What does that mean? I know all clients are aware of all PeerID's as well as which are there own, but that doesn't help my situation.

    To better illustrate WHY I wanted that feature let me explain the sitation:

    1) A player places a booby trap on the host (via input sending of the Z key). To make sure the player can see that trap, the booby trap object is set to sync position so it will be auto-created on all clients.

    2) Only the player who placed the trap should see it, but it needs to also exist on the host so the host can detect player collisions with it authoritatively. If the trap had a synced PeerID instance variable on it, it would be very easy to determine which trap objects should be visible or not.

    I ended up working around this by sending a multiplayer message to the specific player client to place a trap object at his location. This presents a new problem as when the host destroys the trap via triggering it, how do I reliably tell the client who placed it to destroy that specific object instance? I can't use object UID's as those differ between host and client.

    [quote:2vngnzy1]* Vars don't need auto syncing.

    See the above problem. If I want to broadcast a message that an instance variable of instance #5 has changed, how do I make sure the same instance is changed on host and all clients without any consistent UID? The auto-syncing handles this for me. I'm not saying I can't work around this, but it's much hackier and I imagine Ashley's syncing functions are more reliable and efficient than my manual ones would be.

    [quote:2vngnzy1]* As for rubber banding. that's a good point in regards for teleport. But that's an easy fix.

    While I agree with your premise, the specific context is local input prediction combined with the wrap behavior. Especially when the local input prediction is combined with object acceleration. In this case I have flying airplanes, but you could get the same issue with a multiplayer version of asteroids.

    You can try a slightly older buggier version of both games here to better understand:

    http://microwebdiner.com/carnage2/

    http://microwebdiner.com/traps2/

    The point of the plugin is to provide user friendly multiplayer features. If I wanted to do things the harder way I wouldn't be using Construct 2 in the first place would I? There's no shame in ASKING for features, I'm not demanding them.

  • If you want to modify the html that is exported from C2 open up the html that you'll be using in

    C:\Program Files\Construct 2\exporters\html5\templates

    For example, the normal HTML5 with Full Screen turned on is export-fs.html.

    You can remove the cache manifest reference from the top of the html.

    Hope that helps! The caching drives me nutssss when not working on full release versions...

  • I've been wanting to do a similar "Double Dragon" style beat-em up style and run into the same problem. The only way I can think to reduce framerate issues is to use a combination of layers for static objects and the dynamic layering stuff only for objects that can change their Y (players and enemies usually). Generally both the background and "ground" can just be a flat image on the bottom layer.

    If you find a better solution, please share it!

  • If they all numbers you could simply sync them as part of a synced object. Otherwise you can broadcast peer messages whenever they are changed. Just make the message ID the global var name and the message the value.

    Attached a screenshot showing this in action.

  • I have a game where after a long period of play, objects will start mysteriously disappearing or appearing invisible, including the peer objects. It's based on the real-time multiplayer example: http://microwebdiner.com/traps2/

    I have a theory the disappearing trap objects may be related to collision sync issues, but there's no good explanation for invisible peers.

  • I'm sure Ashley already has an agenda for the Multiplayer feature, but I thought i'd weigh in after having made a few different multiplayer game prototypes as to what features I would find really useful:

    * Lobby system. The room system is awesome, but without a room listing system it's pretty hard to help players join each other.

    * Sync text instance variable. With the Peer ID being a string instead of a number, I have no way to properly attach the Peer ID on objects created and synced from the host, and have that PID synced to the clients. It's been very problematic for when clients need to know who "owns" a particular object. This is especially a problem as UID's are not the same between host/client. As a workaround I can assign and sync the host UID as an instance variable and use messaging to pass the Peer ID assignment, but this is pretty hacky.

    * On Instance Variable Sync Change event. When the instance variable of an object is synced and an actual change to the instance variable is synced to the client, I'd really like for the client to know about it without me constantly polling. For example I often use multiple frames in an object as states rather than animations and if the animation frame changes on the host, there's no way to sync that change over to the client other than a peer message (see the above point for the object uid issues that come along with that...) or having the client check the instance variable for a specific value EVERY TICK. With that sync event I could simply update the animation frame from an aframe instance variable anytime (and only when) it changes.

    * A good solution to the rubber banding effect you can get when performing extreme position changes to sync'd peer objects. This happens when a player dies and moves back to the start position, as well as when using the layout Wrap behavior (which I badly want to use in a game).

    Nice job fixing the issue with Scroll To. My solution has been to use a single pinned object with Scroll To and attach it to YOUR peer, but that sometimes creates a weird jittery effect since the pinned object can struggle to keep up.

    Those are the main things I've really felt were needed. Other than that, the multiplayer feature is an amazing game changer and totally worth the wait. You are amazing Ashley!

    If anyone has any good suggestions/solutions to the above, I'd love to hear em!

  • You need to either sync the object (see the stuff in the Signaling group for example) or use some form of messaging (Broadcast Message in the Multiplayer object) to tell the peers what is happening so they can do it locally.

    For example if you make kiblast a synced object (Position and Angle) then when you spawn a new one on the host it will spawn them on the peer clients as well.

  • I sincerely hope that snippet isn't what it looks like. If it is then I'm not sure i'd advocate this event. I contacted WaterlooErik by e-mail and asked him to stop by here and clarify. He's pretty under the weather at the moment so it may take a few. In the meantime I still recommend installing and familiarizing yourself with the tools so you are ahead of the game if everything is fine.

    Thijsku as to your questions about what kind of quality control and such there is and what resolutions, etc. All that stuff is addressed in the guide I provided in the publishing sections. Rather than force you to download the PDF I put all the guidelines directly in there but the PDF is linked as well.

    Hope you all are finding the guide useful. I definitely need to figure out the PhoneGap stuff still for those wanting to use that. I sure would love guides like this for other platforms, hint hint ;)

  • RIM is doing a smart thing and populating their Blackberry 10 App store with bazillions of apps before it's even released!

    How you ask? Port-a-thons! They pay you $100 for every app you submit to the store during the 36 hour window plus extra bonuses (like free devices) depending how many apps you submit.

    What makes it a port-a-thon? They support really easy porting of HTML5, Adobe Air and Android apps (as well as native C/C++ and Java). That means your Construct 2 apps may take as little as 5 minutes to port ($100 for 5 minutes isn't too shabby).

    The tools are surprisingly good and the RIM people have been really helpful when I did the event yesterday. Unlike iOS, the process for dealing with keys and all that is pretty smooth, its free (no $100 fee) and everything is multi-platform!

    I did run into a few quirks here and there trying to figure out the process from just navigating the blackberry website on my own so in the interest of being a good citizen I put together a guide on the entire process from setup to publication and more specifically for Construct 2 users (it's all I use anyways).

    Guide: https://rizzoma.com/topic/133aad09189d1f57f31bc4098b2e4aa4/

    I setup the wave to be publicly accessible via the link and allow comments but not editing so feel free to comment away and I'll update things as needed!

    BlackBerry 10 36 hour Last Chance Port-A-Thon

    Start:      Friday January 18, 2013 12:00:00 PM EST

    End:      Saturday January 19, 2013 11:59:00 PM EST

    Unfortunately it starts early on a workday for most but there's nothing stopping you from prepping all of your entries well in advance and submitting them during the window (36 hours is plenty of time to just submit things)!

    I didn't follow the recommendation to do things (such as setup the tools in advance) and definitely regretted it!

    There's definitely some neat things about the platform such as great social features (BBM not only supports cool social graph stuff between Blackberry users, but even allows you to use its network messaging for creating multiplayer games), WebGL support (not sure how well this works yet though, Ashley may have to answer that).

    I don't have any affiliation with RIM or get any kind of kickback or something, I just want to see lots of Construct 2 games on mobile and hopefully this will motivate you all!

    If you need help, WaterlooErik on here is from RIM and was pretty helpful during the last port-a-thon!

    Ashely, any chance you could get an updated PhoneGap (phonegap build doesn't work for bb10 and the current phonegap export doesn't call Cordova, just older phonegap) or BB10 beta export (just add a webworks js call and a basic config.xml to the export!) going before Friday? ;)

  • I see Ashley's point in wanting to stick with optimizing the canvas himself over trying to fight with the browser over how it handles CSS3 tricks, but I'm curious how you would accomplish some of the simple but effective CSS 3D tricks such as a 3D card flip that only requires 2 images (front and back) vs having to trying and animate that with sprite frames.
