i have managed implement smoothstate.js plugin on website , works nicely, other simple jquery plugin not work, wich starts with: $(document).ready() i need refresh page in order work again. i've read smoothstate documentation , says should wrap plugin initializations in function call on both $.fn.ready() , onafter — i'm farely new programming, i'm asking help. how can make jquery plugins work smoothstate? you need wrap scripts initiated $(document).ready() in function, , call function when need it. for example, let’s current script: $(document).ready(function() { $('.btn--homepage').click(function(e) { e.preventdefault(); var goto = $(this).attr('href'); $('#page').addclass('is-exiting'); $(this).addclass('exit-btn'); settimeout(function() { window.location = goto; }, 260); }); }); it’ll work fine when page loads it’s wrapped in $(document).ready(function()) , page won

so how code works is, enemy find player , move towards him. when finds him, stop , start attacking. if player moves away though, enemy stop attacking , sit there until player comes range. how can fix when player moves out of range, enemy starts chasing again , attacks normal? float movespeed = 3f; float rotationspeed = 3f; float attackthreshold = 3f; //distance within attack float chasethreshold = 10f; //distance within start chasing float giveupthreshold = 20f; //distance beyond ai gives float attackrepeattime = 1f; //time between attacks bool attacking = false; bool chasing = false; float attacktime; transform target; //the enemy's target transform mytransform; //current transform data of enemy void update() { //rotate @ player float distance = (target.position - mytransform.position).magnitude; if (chasing) { mytransform.rotation = quaternion.slerp(mytransform.rotation, quaternion.lookrotation(target.position - mytrans

is familiar angular2-seed or project works wso2is-5.x.0 authentication? what similar seed auth0: https://github.com/auth0/auth0-angular2/ but instead of authentication towards simple express server in backend, authenticate towards wso2is. alternatives wso2is, e.g. openam, of course of interest if there angular2-seeds/samples available those... auth0 has lot of examples here: https://auth0.com/authenticate/angular2/ explore other alternatives well.

i want develop application using 4d front end , postgres backend. possible? don't want traces of database in front end i.e @ 4d end. but here problem while opening/running compiled 4d application (exe) or opening structure file in 4d, requires datafile. question can suppress dialog use 4d front end completely. thanks in advance. so question can suppress dialog use 4d front end completely. you need have data file or 4d prompt user asking create or open one, if there no tables in application. if using v15 or higher can take advantage of default data folder in suppressing "select data file" dialog. quote the docs opening data file when user launches new or updated merged application (single-user or client-server) first time, 4d tries select valid data file. several locations examined application successively. the opening sequence launching merged application is: 1) 4d tries open last data file opened (not applicable during
