i have question how closures work in relation garbage collection. have created javascript application seems continually adding objects don't cleaned when create new project. in code application clears out references newly created objects , make sure unbind events , dispose them. when in chrome heap profiler see: when click on references of objects can see there pointers objects in jquery proxy function. (specifically variable 'context') from can see, proxy function creates closure , closure has reference viewport when constructed. how i'm using proxies in viewport3d: //in constructor of viewport3d this.keydownproxy = jquery.proxy( this.onkeydown, ); jquery(document).on( "keydown", this.keydownproxy ); ... //in dispose method of viewport jquery(document).off( "keydown", this.keydownproxy ); this.keydownproxy = null; so can see removing events nullifying proxy closure reference exists. so why viewport3d still exist in memory after e...

i developing online networking game using box2d js , vert.x server->client framework. i have searched pros , cons of each , believe dynamic time step better since not assume each client has same processing power, however, there (many) people think fixed time step better. please enlighten me. you can throw determinism out window if timesteps not synchronized. when are, determinism difficult. spending less computation on simulation have real costs may not apparent. each different setting (and in case of dynamic timesteps/iterations, each different individual execution) resulting behavior on same input can different. can have user run on slow hardware can potentially cheat through levels. determinism perhaps marginally less important outside of multiplayer engine context, not having deterministic system make more difficult reason pretty (gameplay mechanics, game difficulty, exploits) can impact every kind of game can think of. imagine puzzle game wasn't determi...
