can my "big" project work in construct?

  • Greetings Construct users!

    I have in the past made many minor casual projects on programs such as RPG Maker, Construct classic and 2, etc. Lately me and my friends have been throwing around a project idea and considering making it a serious game. The only issue is find the right game making engine for our project.

    Basically the first thing I need to get out of the way is that online capabilities is a must. I have seen that construct has pulled this off to some extent. The ability to face other people and have a rankings system of some sort is really the meat of it though.

    What we are working on is a turn based strategy, that also has a 2D side scrolling shoot em up in there (recruit guys in the shoot em up for the turn based). Graphically this game wouldn't be intensive, and I have been able to make shells of both parts of the game in construct, though not yet combine the two. We have some graphic designers and programmers on board with us, and I myself am of the business/accounting professions.

    Is this project doable in Construct? Do you guys know a better program for this project?

    Any and all feedback would be greatly appreciated

  • Hi !

    C2 sounds perfectly suitable for this project ; just be aware that the built-in multiplayer functionalities are designed around the host/peer architecture, not server/client. It may or may not be an issue depending on your concept

  • just be aware that the built-in multiplayer functionalities are designed around the host/peer architecture, not server/client. It may or may not be an issue depending on your concept

    "host" and "peer" are just different names for "server" and "client", it's the same architecture. The connections are what go peer-to-peer, but it's still an authoritative server model - the host acts as the server.

  • Don't know about multiplayer, but "big" project are perfectly fine with C2. My current project is an ecosystem simulation with 7200 events, using largely functions & families, where the world evolves according to natural rules, seasons, animals reproduction, plants getting energy from the sun... thousands objects on a large map having their own life span. So yes, C2 allows you to do a lot of stuff if you know how to.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Absolutely, fair statement - my apologies for the misleading over-simplification, I only mentioned this as a quick way to make sure the OP, who doesn't seem to have used C2 yet, wouldn't expect distinct modules for the client and server sides, like some other tools do, and would need to understand the symmetry between peers to develop proper host "authority" logic

  • Thank you for all the responses. I have continued the research on server functions such as online play and rankings and it seems like a lot of work. Server work 99 to game 1 as a ratio. At least for the server, I may hire someone. Thanks for the feedback guys!

  • best choice youl ever make, using c2 cheers

  • I work with Smartfox 2X Server. (100 user slots is free)

    It is very doable, but very hard to understand for beginners.

    A few hundret lines java, some mysql tables and it does all you want. That is fast done.

    But you also need to write one or more Construct plugins to handle sends and data.

    And you need a RootServer, thats also a problem. Not to buy, but to hold it safe. Better is Photon, it works with cloud, but I dont know how it works...

    In my project, and I think its normal, the Construct part is much bigger! Where, what, when send or get and work with much big dictionarys.

    In SFS its only income message, set or get some data, send a message back, no big work.

    To be able to assess the work, I give you an example how a SFS Server extension can look like:
