    Anyone want to Team Up ?

    Im getting back into gaming lately, and I am also slow at work for a while - So I want to finish up my Contra game. Initially ... the idea of contra-2000 was pretty much a battle royale .. so I figure, now that Battle Royales are so popular ... if I called this thing Contra-Royale (or something more clever) it could be pretty good and popular. Im really into fornite, and so is everyone else, so I think the complete gameplay will be similar ... except for its 2D platformer and Contra. I just pushed up some clean up and a better readme onto the original contra-2000 github repo. If anyone shows any interest in helping...i'll get it back onto AWS so we can check it out in action. But there is plenty left to do....generally Id group it a few areas. client side - art / sound / ui / level design client side - gameplay mechanics / new features / gameplay events server side - game logistics / game management / messaging ops crap - aws / deployment / etc Thats all - if anyone is interested I'd love to hear from you. PM me or just comment here. You can see how that contra game looked when I stopped last year in the gallery....https://github.com/melonjs/melonJS/wiki/made-with-melonJS -chris

    Run without rendering (for online game)

    You mentioned my game (Contra) so I'll comment on what I think. Don't try to solve problems you don't have....you're game would need to be really popular before anyone would bother with cheating....I am NOT saying that you're game wont be popular (I bet it will be awesome)....point is - first goal should be creating a great multiplayer game that works well. When I started to make the multiplayer parts of my game I had no clue what to do (I still dont). At first I got lost in the advanced concepts, but I stepped back and just wanted to make it work. Of course you can cheat my setup...the server has zero validation. But why on earth would anyone be cheating. I made Contra as simple as possible...each client handles his own gameplay...client publishes updates of his own player's state to the server...the server then broadcasts that state to all other clients. When each client recieves another player's state update...the client simply tells that player's character to run over to that reported position. Running a Java server is probably an odd idea (but I think it has merit). My motivation - curiosity about some new reactive functional frameworks for java. A better idea might be running a simple node server using sockJs or some other pub-sub library. Or even just vanillaJS using node's HTTP module and RXJS. Anyhow .... This way (theoretically) ... when the time comes ... your client side JS code could be moved into you're server-side JS code.

    Contra 2000

    A while back, I was here making a multiplayer Contra. I finished it up a few months ago and moved on....but I decided i'd share the results and the source code with anybody interested. It came out pretty good....I called it Contra-2000. Ive actually played the thing quite a bit with my 7 year old..he really likes it. Its buggy and raw but works well. The multiplayer came out very nice. Also...big huge THANKS to all the devs on the site...you guys are super helpful. And the melonJs is really solid and easy. I will definetely be recommending it strongly. Below is link to the source code ... there are videos on there so you can see the game play. https://github.com/chrisDaniel/contra-2000 I dont keep the server running. The game eats network ... and AWS charged me 9 dollars!

    melonjs zooming and panning

    I needed the zoom as well today and came across this post. I copied in your code above and the plan didn't really work right away....simple quick fix for me was to use a constant value of 1.02 for zoom out and .98 for zoom in. Seems like, from the partial code above, your idea is to keep a scale variable which you are incrementing and then applying. Which doesnt seem correct becuase [viewport.currentTransform.scale(game.data.scale) ] doesn't set a scale value it just multiplies the current values in the transform matrix. Hopefully that helps....maybe not.

    Rendering Question

    Perfect! Thanks!

    Rendering Question

    First off....everything is working correctly. But I have a question about how the render update is working. See.....I am testing across two open browser sessions in chrome; each are receiving socket messages to update the position of the players in the game....like the picture below.... Both of the open browsers are showing receipt of messages the whole time....But I have to actually be engaging with a window for that specific window to redraw the page. Bottom line...I cant seem to see the updates from screen 1 effecting screen 2 in real time....I have to go click on screen 2 at which point screen 2 immediately draws it correctly. Is there a quick way to explain what the rendering is doing? Im hoping that it would be pretty enlightening for me to understand this....maybe its simple, but I cant seem to figure whats happening.

    New User - Is melonJS right for this Game?

    Thanks for the feedback Jay....the collection of links in the "rabbit hole" are pretty tremendous. And nope, Ive never made a multiplayer game at all. As for melonJS...the framework is really tremendous so far....Ive got a contra map from tiles I cut off old images on the web, plus sprites. Then coded up my entities , and already have a pretty decent looking and working Contra game. So Big High5 to the melonJS devs. Now im wading into the multiplayer....Ive got websocket messaging flowing between client and a server. So easy part done. I suppose from what I read .... the correct approach includes... 1. Server acts as master system of record 2. Clients see the other users as they were in the very slight past and interpolate the gaps. 3. Implement lag compensation on server calculations which kinda reverses that interpolation from step 2. But it seems to me the implementation of that will be a bit bizarre in a game like Contra....because the bullets are moving so slow! But maybe it makes easier, who knows? Its an interesting problem area for sure. Thanks again!

    New User - Is melonJS right for this Game?

    Thanks for the quick reply agmcleod.... Im going to give melon a go I think. I just worked through the Platformal tutorial and it was very easy to get the thing stood up and a game working. So far so good.
  9. This post is from a first time melonJS user. I would love guidance and advice from strong members of the community. Let me know if this is sounds like a good/interesting idea. Is this something melonJS will do well? Game Summary Massive Multiplayer Team Contra (looking exactly like NES contra) Hook: Its a neverending multiplayer Game session. As a player joins the session they are auto-teamed up with 1 random new player . These teams compete to get to top of leaderboard (so kinda similar to slither.io in many respects) Rules: Exactly like contra...1 bullet takes a life. Each player starts with three lives. As a team is killed off, the team is removed from the game and leaderboard. New teams are always being added to the game. If your teammate is killed off...you are alone, but will have opportunity to join another player Why Im Posting This Ive never made a game for browser, after looking around Im almost settled on using melonJs. Im a very experienced server side developer and will also be building a multiplayer micro-server specifically for the game. This server will be responsible for coordination between players (lobby and in-game). It will also do some of the heavy in-game calculation lifting. It will service the clients via websockets and REST. The browser is where Im unsure. Ive done Javascript when I needed it, but Im no expert. Here is what I need melonJS to do for me. Render the game (of course). Do physics / collision detection for the player. (not all players .... just the main player for that browser instance) As new players are added the map will possibly grow. With some upper limit. Take instruction from the server on the game state (other entities and they're actions) Use RX-JS for this interaction with the server (I specifically want to learn RX-JS). So this will require Observable streams to be processed alongside the game loops. Thanks for any feedback! -chris
