c# - How to fix the below error in the simple chaser program in unity 3d? -


i new unity 3d , c sharp. designing program in sphere chasing cube . tried it's showing error.

error in console :

assets/chaserr.cs(8,40): error cs0019: operator `-' cannot applied operands of type `unityengine.transform' , `unityengine.vector3' assets/chaserr.cs(11,38): error cs0019: operator `+' cannot applied operands of type `unityengine.vector3' , `float' assets/chaserr.cs(11,27): error cs1502: best overloaded method match `unityengine.transform.translate(unityengine.vector3)' has invalid arguments assets/chaserr.cs(11,27): error cs1503: argument `#1' cannot convert `object' expression type `unityengine.vector3'

chaserr.cs

using unityengine; using system.collections;  public class chaserr : monobehaviour {     public transform target;     float speed = 8;     void update () {         vector3 displacement = target - transform.position;         vector3 direction = displacement.normalized;         vector3 velocity = direction * speed;         transform.translate (velocity + time.deltatime);     } }

move.cs

using unityengine; using system.collections;  public class move : monobehaviour {     float speed = 10;     void update () {         vector3 input = new vector3 (input.getaxisraw ("horizontal"), 0, input.getaxisraw ("vertical"));         vector3 direction = input.normalized;         vector3 velocity = direction * speed;         vector3 moveamount = velocity * time.deltatime;         transform.translate (moveamount);      } }

if want other other information please please comment..

instead of

vector3 displacement = target - transform.position;

use 

vector3 displacement = target.position - transform.position;

and

instead of

velocity + time.deltatime

use

velocity * time.deltatime

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 ...
