Randomize Loot drops

[c0ncrete]

this is a trimmed down version of the plugin i use to give a random item to an npc.

#!/usr/bin/perl

# select a random itemID and give to npc
# returns itemID added
sub GetRandomItem {

    # defult itemid
    my $itemID = 0;

    # get npc object from calling script
    my $npc = plugin::val('$npc');

    # bail if npc has no loot table
    if ( !$npc->GetLoottableID() ) {
        return 0;
    }

    # bail if missed chance for extra item
    # assuming mob level tops at 80, this should max our chance @ 10%
    if ( rand(100) > $npc->GetLevel() * .1 + .2 )
    {
        return 0;
    }

    # find valid item id to give to npc (attempts until it gets an item name)
    # 1001 is min and 132476 is max itemID in database at time of writing
    my $itemName = 0;
    until ($itemName) {
        $itemID   = int( rand(131475) + 1001 );
        $itemName = quest::getItemName($itemID);
    }

    # have npc equip item, where possible
    $npc->AddItem( $itemID, 1, 1 );
    $npc->Heal();

    return $itemID;

}

1;

this is a trimmed version of the python script i used to modify all of the existing script files. as it stands, it is set up to run from a folder i use to keep up to date with the latest svn located in the EQEmu folder along with the running Quests directory. it adds EVENT_COMBAT to all existing npc scripts where needed (which is where the loot is added), and simply modifies the event if it already exists.

import os, sys

written  = 0
modified = 0

zone   = ''
script = ''

def getScriptList(zone):
    script = []
    for entry in os.listdir(zone):
        if os.path.isdir(entry):
            continue
        script.append(entry)
    return script

def modEventCombat(content):
    # modifying or adding EVENT_COMBAT
    found = 0
    start = 0
    for idx, val in enumerate(content):
        if found:
            break
        if val.find('EVENT_COMBAT') > -1:
            found = 1
            start = idx
            if val.find('{') == -1:
                start = start+1
            break
    if found == 1:
        content.insert(start+1, '\tif($combat_state) { plugin::GetRandomItem(); }\n')
    else:
        content.insert(0, 'sub EVENT_COMBAT\n{\n\tif($combat_state) { plugin::GetRandomItem(); }\n\n')
