Help Using Groups/Layers On Pick

by Unk · in Torque Game Builder · 07/18/2006 (3:44 pm) · 5 replies

Hey guys,

Can someone post a working example of how to utilize Groups/Layers on a Pick function like PickPoint? (Please don't quote the reference as I have that already.)

I have tried all combinations I can think of but whenever I do a pick when specifying a graphgroup or layergroup my list comes up empty.

I have tried this with the original 1.1.0 install build and from a CVS debug build from 6/28.

Thanks for your help.

-----------------------------------------------

THIS RETURNS A LIST:

%pick = $scenegraph.pickPoint(%posx,%posy);

-----------------------------------------------

THESE VARIATIONS DO NOT:

%pick = $scenegraph.pickPoint(%posx,%posy,1,1);

------

%pick = $scenegraph.pickPoint(%posx,%posy,"1","1");

------

%pick = $scenegraph.pickPoint(%posx,%posy,BIT(1),BIT(1));

------

%groupMask = 1;
%layerMask = 1;

%pick = $scenegraph.pickPoint(%posx,%posy,%groupMask,%layerMask);

------

%groupMask = Bit(1);
%layerMask = Bit(1);

%pick = $scenegraph.pickPoint(%posx,%posy,%groupMask,%layerMask);

------

%pick = $scenegraph.pickPoint(%posx,%posy,%groupMask = 1,%layerMask = 1);

------

%pick = $scenegraph.pickPoint(%posx,%posy,"%groupMask = 1","%layerMask = 1");

This is interestning... I haven't tried using masks on pick calls. I'll try it out and get back you you.

I appreciate it, man. I am pretty sure I must be setting the parameters wrong but I couldn't find any source to compare it to.

While I wasn't able to filter the results of a pick when calling the pick itself, I realized that it wouldn't be that difficult to appy a filter on the backend. Incase anyone else is trying to do something similar here are the utility functions I came up with:

function filterByGraphGroup(%picklist,%graphgroupfilter)
{
   %slots = (getWordCount(%picklist) - 1);
   
   for(%slot = 0; %slot <= %slots; %slot++)
   {
      %ID = getWord(%picklist,%slot);
      %group = %ID.getGraphGroup();
            
      echo("===== Processing FilterByGraphGroup - Slot:" SPC %slot @ "/" @ %slots SPC "- ID:" @ %ID @ " =====");
      echo("Current List:" SPC %picklist);
                  
      if(%group != %graphgroupfilter)
      {
         %picklist = removeWord(%picklist,%slot);
         
         %slot -= 1;
         %slots -= 1;
         
         echo("ID:" @ %ID SPC "Removing From List - Mismatched Groups:" SPC %group @ "/" @ %graphgroupfilter);         
         echo("New List:" SPC %picklist);
      }
      else
      {
         echo("ID:" @ %ID SPC "Passed Filter");
      }
   }

   echo("Done Processing List:" SPC %picklist);   
   return %picklist;
}

function filterByLayer(%picklist,%layerfilter)
{
   %slots = (getWordCount(%picklist) - 1);
   
   for(%slot = 0; %slot <= %slots; %slot++)
   {
      %ID = getWord(%picklist,%slot);
      %layer = %ID.getLayer();
            
      echo("===== Processing FilterByLayer - Slot:" SPC %slot @ "/" @ %slots SPC "- ID:" @ %ID @ " =====");
      echo("Current List:" SPC %picklist);
                  
      if(%layer != %layerfilter)
      {
         %picklist = removeWord(%picklist,%slot);
         
         %slot -= 1;
         %slots -= 1;
         
         echo("ID:" @ %ID SPC "Removing From List - Mismatched Layers:" SPC %layer @ "/" @ %layerfilter);         
         echo("New List:" SPC %picklist);
      }
      else
      {
         echo("ID:" @ %ID SPC "Passed Filter");
      }
   }
   
   echo("Done Processing List:" SPC %picklist);
   return %picklist;
}

function filterByGraphGroupAndLayer(%picklist,%graphgroupfilter, %layerfilter)
{
   %slots = (getWordCount(%picklist) - 1);
   
   for(%slot = 0; %slot <= %slots; %slot++)
   {
      %ID = getWord(%picklist,%slot);
      %group = %ID.getGraphGroup();
      %layer = %ID.getLayer();
                  
      echo("===== Processing filterByGraphGroupAndLayer - Slot:" SPC %slot @ "/" @ %slots SPC "- ID:" @ %ID @ " =====");
      echo("Current List:" SPC %picklist);
                  
      if((%group != %graphgroupfilter)||(%layer != %layerfilter))
      {
         %picklist = removeWord(%picklist,%slot);
         
         %slot -= 1;
         %slots -= 1;
         
         echo("ID:" @ %ID SPC "Removing From List - Mismatched Group or Layer - Group:" SPC %group @ "/" @ %graphgroupfilter SPC "- Layer:" SPC %layer @ "/" @ %layerfilter);         
         echo("New List:" SPC %picklist);
      }
      else
      {
         echo("ID:" @ %ID SPC "Passed Filter");
      }
   }
   
   echo("Done Processing List:" SPC %picklist);
   return %picklist;
}

This way you can get the results of a pick by passing in a position. Then call one of the utility functions to remove every id from the pick list that does not match the filter.

%pick = $scenegraph.pickPoint(%posx,%posy);

//THEN

%pickid = filterByGraphGroup(%pickid,1);

//OR

%pickid = filterByLayer(%pickid,1);

//OR

%pickid = filterByGraphGroupAndLayer(%pickid,1,1);

I would still be interested if someone figures out how to get this working inside the pick function. I am starting to suspect it is a bug.

[Update:]

Below is an update to these functions plus a couple additional functions (changes marked in bold).

These functions are primarily helpful for filtering a list of objects at the mouse position by layer and graphgroup.

All of these functions apply one of these filters to a tab delimited list of id's stored in a string:

[b]filterByGraphGroupFilter(string,graphgroup number)[/b] - filters by passed in graph group
  [b]filterByLayerFilter(string,layer number)[/b] - filters by passed in layer)
  [b]filterByGraphGroupAndLayerFilter(string,graphgroup number,layer number)[/b] - filters by both graph group and layer.

In addition, there are three new functions that call a pick prior to applying a filter:

[b]getPickPoint(object id, filter,graphgroup number, layer number[/b]) - Gets objects at object pos and applies given filter.
[b]getPickPointByPosition(position, filter,graphgroup number, layer number[/b]) - Gets objects at given position and applies given filter.
[b]getPickRadius(object id, radius, filter,graphgroup number, layer number[/b]) - Gets objects in radius around given object position and applies given filter.

I also corrected a bug where the filters would return a string with trailing whitespace which does not get ignored when concatenating strings.
