i developing flight simulator programme. right trying level restart after delay of 4 seconds, instead waiting forever , not responding. code (in c#) right now: void update () { //other irrelevant code in front float terrainheightlocation = terrain.activeterrain.sampleheight (transform.position); if (terrainheightlocation > transform.position.y) { //the plane crashed startcoroutine(wait(terrainheightlocation)); } } ienumerator wait( float terrainheightlocation) { transform.position = new vector3 (transform.position.x, terrainheightlocation, transform.position.z); instantiate(explosion, transform.position, transform.rotation); destroy(gameobject); debug.log ("waiting"); yield return new waitforseconds(4.0f); // waits x seconds debug.log ("waited x seconds"); application.loadlevel(application.loadedlevel); debug.log (...

so have following query trigger: delimiter $$ create trigger user_log_update before update on user_log each row begin insert user_log (id, user_id, name, username, password, email, user_type_id, created) values(old.id, old.user_id, old.name, old.username, old.password, old.email, old.user_type_id, old.created); if (old.id = 1) set old.id = old.id +1; end if; select * user_log; end$$ delimiter ; when try execute part of script, error code: 1362. updating of old row not allowed in trigger i don't know why got error , don't see wrong in syntax. does know how fix it? so, increment new instead: delimiter $$ create trigger user_log_update before update on user_log each row begin insert user_log(id, user_id, name, username, password, email, user_type_id, created) values(old.id, old.user_id, old.name, old.username, old.password, old.email, old.user_type_id, old.created); if (old.id = 1) set new.id = old.id +1; end if; end$$ delimiter ...

this entirely different question 1 asked before why i'm posting this. i define topic subjective question inspires answers explain "why" , "how". allowed according help center rules. in order make question more constructive, provide resources better explain topic. from c++ superfaq under question "can give me simple reason why virtual functions (dynamic binding, dynamic polymorphism) , templates (static polymorphism) make big difference?" the author says, "...a programmer might write code called framework written great, great grandfather. there’s no need change great-great-grandpa’s code. in fact, dynamic binding virtual functions, doesn’t need recompiled.even if have left object file , source code great-great-grandpa wrote lost 25 years ago, ancient object file call new extension without falling apart." he goes on say, "that extensibility, , oo , generic programming powerful reusable abstraction." furthermore, re...

i'm trying better understanding of gcd wrote test code below (bottom). 2 functions waits inside sent on different queues , println on main thread waiting particular tasks. i expect console output should be: before functions start 3 sec loop start 5 sec loop end 3 sec loop between functions wait on long after functions wait on long end 5 sec loop between functions wait on longer after functions wait on longer but instead is: before functions start 3 sec loop start 5 sec loop between functions wait on longer after functions wait on longer end 3 sec loop between functions wait on long after functions wait on long end 5 sec loop a number of things don't make sense me - 1. why "longer" ones printed before "long"? 2. why "longer" ones not printed after end of longer i.e. 5 second function? code (viewcontroller.swift) import uikit class viewcontroller: uiviewcontroller { var longqueue = dispatch_group_create() var longerqueue ...
