unreal results

[Suhad Faisal]

Hello 

please, can I have any comments about my values (source, target) I want to deal  with 2 successive list elements of same list 

     point source  <- localy INDEX i   ;

      point target   <-  localy INDEX i+1 ;

  

       if  (source != target)

             

                distance   <- source distance_to target  ; 

                

     

cheers

Hi,

the index_of operator returns : 

"the index of the first occurrence of the right operand in the left operand container".

https://code.google.com/p/gama-platform/wiki/G__OperatorsAK#index_of

Note that this YOUR model, so we do not have any idea of what means "unrealistic results"...

Hello 

please, can I have any comments about my unreal resulted values (source, target), in spite of the model runs normally ... is the operator "index_of" is mal used ? 

reflex w {

loop i over: alias {

      localy   <- list<float>(self.location);

      towery  <- list<int>(self.tower); 

      aliasy   <- list<int>(self.ali)  ; 

              timery   <- list<int>(self.timy) ;

     point source  <-point(localy index_of i)   ;

     int sourcetime<-timery index_of i;

            

     point target  <-point(localy index_of (i+1)) ;

     int targettime<-timery index_of (i+1)        ;

  

       if  (source!=target)

         {      difftime   <- abs(float(sourcetime-targettime)); 

                distance   <- source distance_to target  ; 

                speedy     <- (distance/difftime)        ;    }  

      

           do  goto target:target on:shape return_path:true speed:speedy; 

                 }   }

cheers
