c# - How do i delay a function after the handled device ends shake? -


i'm developing game on unity3d. here have 5 cards, , i'm trying shuffle them shake movement, but, code, cards being shuffle while shake performed, need that function can delayed or start when shake ends. here code:

using unityengine; using system.collections; using unityengine.ui;  public class shake1 : monobehaviour {      int numtimes = 50;      public image personajes;     public image lugares;     public image situaciones;     public image emociones;     public image objetos;     public gameobject camshake;       float accelerometerupdateinterval;     // greater value of lowpasskernelwidthinseconds, slower filtered value converge towards current input sample (and vice versa).     float lowpasskernelwidthinseconds;     // next parameter initialized 2.0 per apple's recommendation, or @ least according brady! ;)     float shakedetectionthreshold ;      float lowpassfilterfactor;      vector3 lowpassvalue;     vector3 acceleration;     vector3 deltaacceleration;      void start () {         lowpasskernelwidthinseconds = 1.0f;         accelerometerupdateinterval = 1.0f / 60.0f;         lowpassvalue  = vector3.zero;         lowpassfilterfactor = accelerometerupdateinterval / lowpasskernelwidthinseconds;     }     public vector3 lowpassfilter(vector3 newsample){         lowpassvalue = vector3.lerp (lowpassvalue, newsample,lowpassfilterfactor);         return lowpassvalue;         }      void update () {         acceleration = input.acceleration;         deltaacceleration = acceleration - lowpassfilter (acceleration);          if (mathf.abs (deltaacceleration.x) >= 0.2 && mathf.abs (deltaacceleration.y) >= 0.2 && mathf.abs (deltaacceleration.z) >= 0.2) {             (int = 0; < numtimes; i++) {                 handheld.vibrate();                 if (personajes.transform.parent.name == "panel_superior") {                     personajes.sprite = resources.load<sprite> ("cartas/pillow-cards-" + random.range (2, 13)) sprite;                 }                 if (situaciones.transform.parent.name == "panel_superior") {                     situaciones.sprite = resources.load<sprite> ("cartas/pillow-cards-" + random.range (28, 39)) sprite;                 }                 if (emociones.transform.parent.name == "panel_superior") {                     emociones.sprite = resources.load<sprite> ("cartas/pillow-cards-" + random.range (41, 52)) sprite;                 }                 if (lugares.transform.parent.name == "panel_superior") {                     lugares.sprite = resources.load<sprite> ("cartas/pillow-cards-" + random.range (15, 26)) sprite;                 }                 if (objetos.transform.parent.name == "panel_superior") {                     objetos.sprite = resources.load<sprite> ("cartas/pillow-cards-" + random.range (54, 68)) sprite;                 }             }         }     }  }

as update() called @ 60hz, can create counter (let's it's called zeroacc) increased everytime acceleration below triggering threshold of "shake".
@ same time shake triggered, can store value of zeroacc @ moment, let's acctri.
need decide delay, example 30 calls of update(), , trigger callback.
this: 

void update(){ //keep code have , add this:     if (zeroacc - acctri > 30) {         callback ();         acctri = int.maxvalue; //we don't want trigger again     } }

jOOQ update returning clause with Oracle -

according http://www.jooq.org/doc/3.8/manual/sql-building/sql-statements/update-statement/ jooq doesn't support returning clause in update statements databases except firebird , postgres. does know, still correct oracle jooq? according oracle's documentation, oracle db supports returning clase delete, insert, or update statements. incorrect manual you're right - manual wrong , should fixed: https://github.com/jooq/jooq/issues/5470 single row update returning jooq 3.8 added support single row update .. returning statements. internally, uses callablestatement , pl/sql block of form: begin update "my_table" set "my_table"."column" = 'xyz' "my_table"."id" = 1 returning "my_table"."id", "my_table"."column" ?, ?; ? := sql%rowcount; end; the relevant issue is: https://github.com/jooq/jooq/issues/5190 multi row update returning a...

java - Warning equals/hashCode on @Data annotation lombok with inheritance -

i have entity inherits other. on other hand, i'm using lombok project reduce boilerplate code, put @data annotation. annotation @data inheritance produces next warning: generating equals/hashcode implementation without call superclass, though class not extend java.lang.object. if intentional, add '@equalsandhashcode(callsuper=false)' type. is advisable add annotation @equalsandhashcode (callsuper = true) or @equalsandhashcode (callsuper = false) ? if not added, 1 callsuper=false or callsuper=true ? the default value false . 1 if don't specify , ignore warning. yes, recommended add @equalsandhashcode annotation on @data annotated classes extend else object. cannot tell if need true or false , depends on class hierarchy, , need examined on case-by-case basis. however, project or package, can configure in lombok.config call super methods if not direct subclass of object. lombok.equalsandhashcode.callsuper = call for configuration system ...
