  • Thanks, but I'd rather stay within C3 ...

  • Has something like this been done before in C3

  • I noticed a nodejs interface (via npm) to prolog is it possible to install this into construct3

  • thank you.

    I eventually noticed the create object, and now consistently create a new JSON in each new function body -- with the message to be parsed passed as argument.

    Its more overhead, but i hope like this i don't get into reentrant problems

  • Thank you.

    Yes, good point.

    That is what i eventually did -- a lot of ping pong'ing between the the C3 game and the peer app.

    But, i guess, the hanging problem could be avoided if the communication happens in a seperate thread -- if its possible easily to do

  • I am displaying a listbox and am using the following CSS to change the font size of individual items, but it doesnt work?

    What am I missing?

    .no_border {

    border: none;

    overflow: hidden; /* Hide scrollbars */

    text-align: center;

    font-size:32px;

    }

  • Hello,

    I am writing some code that receives a websocket message from an outside source that is then parsed by a JSON object.

    Once parsed additional processing is handed off to other functions, which are called and refer to the same JSON object.

    I started to wonder if this is all reentrant -- i.e. when during the processing of one websocket message another one arrives, whether the second set of calls are done via an new JSCON instance, or whether the same is reused / overwritten.

  • I now noticed Redis and a node.js redis client. Perhaps, a more robust connection to peers is via such an infrastructure.

    Can Redis be used in construct3 via node.js?

    I guess, one would need to import node.js and then install into it the redis client -- can this be done in construct 3.

    And, then i guess I would write some interface functions to use within the game code.

  • Hello,

    I have been connecting a game with a peer system using websockets. However, I now noticed that websockets is purely asynchronous, and at times the peer system needs to request data from the game -- and best if its synchronous request, so that the peer obtains the requested data immediately.

    WebSockets doesn't support that -- i would need to code a synchronous "fetch" via coordinated asynchronous calls.

    However, I then thought that a construct 3 game could in fact run a web server as well, and then a web request could be submitted?

    Can this be done?

    Is there another way to do this?

  • I guess that's how it works -- you always have to do the picking as part of the event condition -- you can't pick as part of the action.

    This means that either event conditions must be parameterized -- somehow -- or event conditions must be duplicated to account for all instance identification cases.

    The latter isn't good because it fixes the number of instances assumed existing.

  • Thanks for asking.

    Instances have instance variables defined. One variable is name, which is a string holding a given, unique name on an instance.

    All instances have a unique name predefined.

  • Hello,

    After a long while I am restarting C3 coding again.

    I have an object (say a car) with a moveto behavior, and want an instance of the car to move to an instance of another object.

    The car is named, and the first car instance is selected by having in the event a condition that picks the car instance by name.

    This worked, and I managed to get the first car instance selected after an event, based on the instance's name, but i don't know how to use the MoveTo command to let car move to a first target object instance.

    it seems the only way to do so, is to add another condition to the event that picks the first location by name, which is then "handed" to the moveto ...

    For convenience I don't clone object types but have many named instances in the layout of both cars and named locations they can drive to.

    Is there a way to decouple the selection of the target object instance from the event condition -- so,once an event is received (e.g. start game), then via some lookup a first target instance name is retrieved which is then used to pick the target instance to move to?

    Your help is very much appreciated,

    thank you,

  • Looks like physics and bullet have overlapping functionality -- i like gravity that it enables creating an impact force ... which bullet doesn't have ...

    But, only bullet has on step ...

    oh well ...

  • Thanks!

    I will check out the stepping.

    I didn't want to "fall back" onto drawing lines because it would take away from the smoothness of the curve and hence its "real" nature

  • Hello,

    I am shooting a bullet up at -45 angel and let it fly with gravity and am plotting a parabola of its trajectory on a canvas.

    at every tick i am creating 1 pixel line at the location of the bullet -- and it indeed traces the flight path -- however, i notice that the trace is discontinuous -- many disconnected dots in particular as the bullet accelerates further ...

    Is there a way to actually create a smooth path -- looks like the redraw algorithm is more detailed than each tick.

    thanks,

    Dan
