PHP Code:


		
			
/****
This allows codes to be added to a weapon without
any further editing of the code itself.

(+) addPlugin( pluginType, pluginName, object, function )
  - Adds plugin to system
  - returns data from object.function( default )

(+) remPlugin( pluginType, pluginName )
  - removes plugin

(-) getPlugin( pluginType, default, pluginName )
  - Get the value from a plugin
  - If pluginName is set, from a specific Name

(-) getPlugins( pType )
  - returns Plugin with data
  - if pType is empty, return all plugins

example:
NPC1:
function onCreated()
  {
  NPC2.addPlugin( "listen", "hello", this, "sayHello" );
  }

public function sayHello( pDefault )
  {
  return "Hello";
  }

NPC2:
function listen()
  {
  temp.messages = plugin::getPlugin( "listen" );
  echo( m ); // Returns "Hello"
  }
****/

public function addPlugin( pType, pName, obj, func )
  {
  if ( remPlugin( pType, pName ) )
    { // Removed old!
    this.plugins.add( {pType, pName, obj, func } );
    }

  return true;
  }

public function remPlugin( pType, pName )
  {
  for ( i = 0; i < this.plugins.size(); i ++ )
    {
    if ( this.plugins[i][0] != pType )
      continue;
    if ( this.plugins[i][1] != pName )
      continue;
    
    this.plugins.delete( i -- ); // deletes this index, next is same.
    return true; // Shouldn't have two copies...
    }
  return true;
  }

function getPlugin( pType, pDefault, pName)
  {
  for ( p: this.plugins )
    {
    if ( pType != p[0] )
      continue;
    if ( pName != null && pName != p[1] )
      continue;

    pDefault = p[2].(@ p[3] )( pDefault );
    }

  return pDefault;
  }

function getPlugins( pType )
  {
  if ( pType == null )
    return this.plugins;

  for ( p: this.plugins )
    {
    if ( pType != p[0] )
      continue;
    temp.plugins.add( p );
    }

  return temp.plugins;
  }

I'm confused as to how this could be used...

Same here...

For modular scripts. A plugin would add on to the script itself in a specific part of the code. This could be used for data compilation, or event-catching as well.

What? Couldn't you use scheduleevent to catch events?

I don't really understand the point of this. :confused:

What isn't there to understand? Novo has excelled himself again! Nice work

scheduleevent and catch event are two DIFFERENT things.

Yes, but there is a catchevent function already, though.

From my recollection of catchevent, it catches GUI events only.

Look, Gambet...

If you don't appreciate, or know how to deploy the plugins, than that is very well: I have not, in any way or form, obliged you to use my class.

If you have problems with such, then I suggest you to just find another thread to argue with.

This is one way to skin a cat. YES THERE ARE OTHERS. But any given environment may incite that a particular way is better. This is only another way to do something.

Looks interesting Novo! :D

As for catchevent, I havn't bothered using it outside of GUIs to know whether they only work in GUIs or not but I'm sure you could easily use it outside a GUI function and find out if it works.

Oh I think I did something like this before. I made an EventServer class and objects could use ObjectWithClass.register(Object); and when someone used triggerEvent() it would trigger the event on all objects registered.

Yea... :) But it's slightly different.

You see, the 'event' sends the current value. It then takes the value it returns.

So lets say you want to calculate the level's brightness...

brightness = plugin::getPlugin("brightness", 1 );

The plugin will go and check if any other NPCs plug in... Let's say it is in a house, and our house controller plugged in... The house controller could do return brightness - 0.6; ( thus 1 - 0.6)... Now -- If there are lamps and they plugged in too... return brightness + 0.1; ... If there are three lamps, the total brightness would be 1 - 0.6 + 0.1 + 0.1 + 0.1... Or 0.9.

Using this, you could calculate things, not merely send an event. But, obviously enough, if the value isn't important, it acts as an event.

Gambet... You always go around doing unsupported arguments when you truly don't understand. You have been excessively offensive lately on the forums. It is of my nature to be defensive when someone offensive comes.

VERY nice, thanks for the release!
