Yea... I was talking with Stan, and I was like 'you can't make custom classes using the new operator'... And it dawned: A function call is what you need. Taking inspiration from Java, I created a custom-class. :)

class manager: (DB: Class )

PHP Code:


		
			
public function createClass( className, classes )
{
  if ( (@ className ) != null )
    (@ className ).destroy();

  // Create what it means to be an object...
  echo("Creating class" SPC className );
  temp.newClass = new TStaticVar( (@className) );
  temp.newClass.join( "test_custom_class" );
  temp.newClass.classes = classes;
  
  // Don't let the garabe collecter get this!
  this.classes.add( temp.newClass );
}

public function getClasses()
{
  return this.classes;
}

custom class script: (test_custom_class)

PHP Code:


		
			
public function newInstance( objectName )
{
  if ( (@ objectName ) != null )
    (@ objectName ).destroy();

  temp.newInstance = new TStaticVar( @objectName );
  for ( temp.cjoin: this.classes )
  {
    temp.newInstance.join( temp.cjoin );
  }
  
  temp.newInstance.class = this;
  return temp.newInstance;
}

Testing Class: (test_tnode)

PHP Code:


		
			
/**
 * Nodes Interface for PathFinder
 *
 * (+) void connect( Node node, ... );
 * (+) void disconnect( Node nodes );
 * (+) Node[] getNodes();

/**

  *
  * @param node Node, any object that could be treated as a Node.
  *                If used to connect afterwards, add Node interface!
  **/
public function connect()
{
  for ( temp.node: params )
  {
    if ( temp.node == null )
      return;
    if ( temp.node in this.nodes )
      return;
  
    this.nodes.add( temp.node );
  }
}

/**
  * This removes a node to the node-list.
  *
  * @param node, ... Node, any object that could be treated as a Node.
  **/
public function disconnect( node )
{
  this.nodes.remove( node );
}

/**
  * This obtains the nodes that are currently connected to the object.
  *
  * @return Node[] List of nodes attached to object
  **/

public function getNodes()
{
  return this.nodes;
}

/**
  * This calculates the shortest distance to a particular node.
  *
  * @return Node[] An ordered list of the nodes that need to be traveled
  *                    to reach given destination.
  **/
public function findPath( endNode )
{
  temp.nodeList.add( {this, new[0]} );
  temp.nodeIndex = 0;
  while ( temp.nodeList.size() > temp.nodeIndex )
  {
    temp.node = temp.nodeList[ temp.nodeIndex ][0];
    temp.nodePath = temp.nodeList[ temp.nodeIndex ][1];
    temp.nodePath.add( temp.node );
    if ( temp.node == endNode )
      return temp.nodePath;

    for ( temp.subnode: node.getNodes() )
    {
      if ( temp.subnode in temp.nodeList )
          continue;

      temp.nodeList.add( { temp.subnode, temp.nodePath } );
    }
    temp.nodeIndex ++;
  }

  return null;
}

Example of Usage:

PHP Code:


		
			
function onCreated()
{
  Class.createClass( "TNode", {"test_tnode"} );

  node1 = TNode.newInstance("N1");
  node2 = TNode.newInstance("N2");
  node3 = TNode.newInstance("N3");
  node4 = TNode.newInstance("N4");

  node1.connect( node2 );
  node2.connect( node3, node4 );
  node3.connect( node4 );
  
  nodePath = node1.findPath( node4 );

  echo("Path:");
  for ( node: nodePath )
    echo( node.name );
}

/** Output **
The script of NPC Class has been updated by Novo

Path:

**/

Shouldn't this be in code gallery?

The new operator can be used with an object name or the name of an object type, and when used with an existing object it copies all variables to the new object including this.joinedclasses, causing the classes in the copied object to be joined to the new object.

PHP Code:


		
			
public function onCreated() {
  temp.i = 0;
  this.scriptlogmissingfunctions = false;
  this.types = null;
  // MudObjects
  maketype("MudObject", null, {"util_triggerall", "util_schedulefunction", "type_mudobject"});
  maketype("MudPlayer", TMudObject, {"type_mudplayer"});
  maketype("MudItem", null, {"util_schedulefunction", "type_muditem"});
  // Dialog
  maketype("DialogTopic", null, {"type_dialogtopic"});
  maketype("DialogResponse", null, {"type_dialogresponse"});
  maketype("DialogCondition", null, {"type_dialogcondition"});
  // Misc
  maketype("IniFile", null, {"type_inifile"});
  maketype("DataFile", null, {"type_datafile"});
  maketype("Rectangle", null, {"type_rectangle"});
  this.created = true;
}
public function maketype(typename, super, classes) {
  temp.i = 0;
  if (makevar("T"@typename) != null) {
    makevar("T"@typename).destroy();
  }
  this.(@ "type_" @ typename) = new TStaticVar("T"@typename);
  if (super.type() == 2) {
    this.(@ "type_" @ typename).joinedclasses = super.joinedclasses;
  }
  for (i: classes) {
    this.(@ "type_" @ typename).join(i);
  }
  if (this.types.index("T"@typename) < 0) {
    this.types.add("T"@typename);
  }
}

PHP Code:


		
			
// Use
function onCreated() {
  temp.obj = 0;

  obj = new TIniFile();
  obj.load("data/news.ini");
  // More Stuff
  obj.destroy();

  obj = new TRectangle();
  obj.x = 20;
  obj.y = 20;
  obj.w = 32;
  obj.h = 32;
  if (obj.contains(player.x, player.y))
    echo("Yep!");
  else
    echo("Nope");
  obj.destroy();
}

Hrm! That's a bit weird. Ohwell. Either way. :)

Though I'd like if there was a function called in the class when it was joined and had to be completed before the next class could be joined.

onCreated does not work like this :(

Osnap, Inver beat you to it, Novo. :(

PHP Code:


		
			
public function newInstance( param, objectName )
{
  if ( objectName != "" )
    if ( (@ objectName ).type() == 2 )
      (@ objectName ).destroy();

  // Initialize Class
  if ( objectName == "" )
    temp.newInstance = new TStaticVar();
  else temp.newInstance = new TStaticVar( @objectName );

  temp.newInstance.class = this;
  temp.newInstance.join( ("class_"@ this.name).lower() );

  // Initialize Object
  if ( this.name in temp.newInstance.getfunctions() )
    temp.newInstance.(@ this.name )( param );

  return temp.newInstance;
}

:) I made a turnaround for that onCreated problem. Basically, the newInstance() would call the constructor for the class ( thus, TNode )

PHP Code:


		
			
public function TNode() { foo; }

Makes sure that the initialize variables are initialized immediately.

Such as:

PHP Code:


		
			
function onCreated()
{
 array = TMap.newInstance( {{"Test3", "333"}} );
 array.put("Test", 123);
 array.put("Test2", 123);
 array.put("Test", 321);
 echo( array.toString() ); // output: "Test3,333","Test,321","Test2,123"
}

EDIT: I'm thinking of having an inheritance system working out... So one could probably do an object.class.instanceof( otherclass )... Something along the lines of:

PHP Code:


		
			
public function instanceOf( class )
{
  if ( this == class )
    return true;
  // for ( superClass: superClasses )
  //   if ( superClass.instanceOf( class ) )
  //      return true;
  return false;
}

You're overdoing it as far as Graal goes :P

I tried doing something like that for my Mud system and making it modular and stuff, but its easier to just make a class that does everything at once.

I actually went ahead and did it anyways... So I added inheritance and static functions... :: hums ::

Bah. For some reason, I can't sent it over forums. It says there's a bad request that the server can't understand.

If we had support for global functions the way I wanted (including Control-NPC in the function lookup), it would be a simple and easy deal to have global functions (temp.var = TObjectType();) to return the new object instance.

Anyhow...

I made an addition to my TMap set. For those of you who want to use it, I've made a static function for it:

class_tmap_static (Class)

PHP Code:


		
			
public function merge( map1, map2, mergeRules )
{
  // Sanity Check
  if ( !map1.instanceOf( TMap ) || !map2.instanceOf( TMap ))
  {
    echo("Input aren't TMaps!");
    return null; // Force programmer to input CORRECT Data!
  }

  // Change Merger to supplied one
  temp.oldMerger = this.mergeValue;
  if ( mergeRules != null )
    this.mergeValue = mergeRules;

  // Copy first Map to a new map
  temp.sum = this.newInstance( map1.toArray() );
  temp.keys = temp.sum.keySet();

  // Add second map to new map
  temp.mapSet = map2.toArray();
  for ( temp.mapValue: temp.mapSet )
  {
    // If new map contains given key
    if ( temp.mapValue[0] in temp.keys )
    {
      // Merge them together
      temp.newValue = mergeValue(
        temp.mapValue[0], // key
          temp.mapValue[1], // val1
          temp.sum.get( temp.mapValue[0] ) // val2
        );
      
      temp.sum.put( temp.mapValue[0], temp.newValue );
    } else {
      // Otherwise, put second map data to the new map.
      temp.sum.put( temp.mapValue[0], temp.mapValue[1] );
    }
  }
  
  // Revert back to old merger
  this.mergeValue = temp.oldMerger;  

  return temp.sum;
}

function mergeValue( key, val1, val2 )
{ // Default
  // val1 + val2 should be the same as val2 + val1.
  return (val1 + val2);
}

Example of Usage:

PHP Code:


		
			
function onCreated()
{
  mod1 = TMap.newInstance({{"a",3}, {"b", 1}} );
  mod2 = TMap.newInstance({{"a",2}, {"b", 1}, {"c", 1}} );

  temp.merger = function( key, val1, val2 ) {
    switch ( key )
    {
      case "a":
        return val1 * val2;
      default:
        return val1 + val2;
    }
  };

  mod3 = TMap.merge( mod1, mod2, temp.merger );
  echo( mod3.toArray() ); // "a,6","b,2","c,1"
}

But Powerful for those who know how to use it. Additionally, the merger comes with a default way of merging. It isn't necessary to define your own function, but the power is there if you do!

PHP Code:


		
			
function onCreated()
{
  mod1 = TMap.newInstance({{"a",3}, {"b", 1}} );
  mod2 = TMap.newInstance({{"a",2}, {"b", 1}, {"c", 1}} );

  mod3 = TMap.merge( mod1, mod2 );
  echo( mod3.toArray() ); // "a,5","b,2","c,1"
}

Simple for those who don't need more.

Can you tell me an instance where it would be used in-game?

Sure... Phone-Address look-up. In Era.

PHP Code:


		
			
Phones.phoneMap = TMap.newInstance();

// In various locations around the world
Phones.phoneMap.put("553-4234", this );


// To phone...
otherPhone = Phones.phoneMap.get( "553-4234" );
otherPhone.chat = "*ring* *ring*";

Merger...
Item System:

PHP Code:


		
			
items = TMap.newInstance();
items.put( itemID, {quant, state});

merger = function( key, val1, val2 ){ return {val1[0] + val2[0], val1[1] || val2[1]}; }
items = TMap.merge( items, TMap.newInstance( {{ itemID, quant, 0 }}, merger );

... There are many situations that it could come up.

What I use it for is to have a cumulative effects from the clothing that the player uses.
For instance, let's say 'Speed'...

PHP Code:


		
			
Special Boots = TMap.newInstance( {{"Speed", 5}});
Other Clothing = TMap.n... ...

mods = playerMods;
mods = TMap.merge( mods, racialMods );
for ( clothes: all worn clothes )
  mods = TMap.merge( mods, clothes.mods );

player.speed = mods.get("Speed");

This is done FOR-ALL possible (and future) attributes:

PHP Code:


		
			
  temp.modList = temp.mod.toArray();
  for ( temp.mod: temp.modList )
    clientr.(@ temp.mod[0] ) = temp.mod[1];

That may 'work' but using a specialized function is much simpler and to the point.

I just scan equipped items in the mud object and add their affects to the player's.

You're really over-complicating things that are simple to do with regular scripts. Thats not a good way to bring new scripters into the scene.

Inverness, I've provided quite a dynamic way to do a variety of things. If you don't appreciate it for whatever reason you have (which seems to be whatever you can seem to think of), then that's that. Otherwise... There are MANY ways to skin a cat. This is one of them...

I don't think introducing new programmers to concepts such as these will help... But alternatively, for those in the know, these techniques could be used with a wide range of successful usage. Ultimately, by my publishing the code, I didn't make it ANY HARDER to learn to script. In fact, that wasn't even my targeted audience. (Additionally, new programmers could learn by example, so they might not see the full utility, but something like that could let them see how reflective programming could be done )

Whether it is overcomplicating something, or providing a bigger re-usability... It doesn't matter that much. Sure, some things just need a little function to work. Others will need more. And in the end, everything can be hard-coded as one massive monolith. In fact, you could program Graal in ONE FUNCTION.

Now, if you want to argue the value of TMap... I just provided it as a quick freebie and numerous incidents it could be used. If you're debating about Class System... I think you would already be in a level where you can use it if you considered that it is beneficial to use it in the first place. I provided quite a bit of flexibility.

Ultimately, I AM SORRY FOR GIVING YOU FREE CODE, go cry me a river. ( I refuse to feed your troll habits any further. )

My issue is because I did exact same thing about a year ago and found that it wasted too much time and CPU making things super flexible and modular rather than just scripting it to do what it needs to do in less time.

Though it seems our situations are different if you don't have something you need to be working on and are just scripting for fun. Though, if you do have something you need to do with this all (like making the system for a server) I wouldn't suggest such things.

I'm just trying to save you from wasting time overdoing it :P, redesigning systems and such can kill a server under construction.

Welcome, brothers, to the secret thread of elite scripters! I've got some tea and biscuits on the table.

Hi Dan! Show us your 1337 skillz! I'm sure Inverness is no match to your prowess.
