javascript - How to program quick interaction in multiplayer browser games? -


i have been programming lot of multiplayer browser games in past needed interaction between player, since more strategies , "building" games, interaction not main problem.

i able of stuff jquery, ajax , php this:

  1. someone makes change overall content of game - ajax fires php script stores change in database.

  2. your client side code continuously runs ajax script, each time firing php script searches database changes , if there any, notified or content (html code) of page updated based on changes.

here example of talking about:

setinterval(function() {         $.ajax({         url: "checkupdates.php",         type: "post",         datatype: "json",         success: function(data) {             // changes based on returned data         }     }); }, 1000);

but developing games interaction main factor. let tennis need track position of ball both players movements. simple approach store values in database , update page content mentioned function. not possible because if fire ajax function in quick successions slow down browser. issue there "big" delay between firing ajax function , making changes based on result.

therefore questions are:

  1. is there better way solve problem ajax? approach overcome mentioned problem (firing ajax function every e.g. 0.1 second).

  2. is possible make work in php , relation databases or need use node.js/python backend nosql databases? (which faster guess)

  3. what current state of art in field?

even though might quite broad question, have not find strictly mention approach not suitable.
