Thread: Project Insanity - NPC Drop Tables

Hello,

Although there are probably many instances of snippets with designs similar to this I figured that regardless someone may be able to make sure of this, and even better it.

The concept behind this is simple and it loosely follows a similar design to the actual game. Here are a few things to keep in mind;

• Each npc can have a group of tables (constant, common, uncommon, rare, and very rare)
• The constant table, if existent, is always reached regardless of the 'accessibility' value for the table.
  
  • All items in the table are dropped when the table is accessed
  
  
• The value that determines the rate at which the table will be accessed is not limited or constrained by each of the table polices.
• No npc can have multiple tables with the same policy.

Code:

public class DropManager {
    
    Map<Integer, TableGroup> groups = new HashMap<>();
    
    public void read() {
        JSONParser parser = new JSONParser();
        try {
            JSONArray data = (JSONArray) parser.parse(new FileReader("./Data/json/npc_droptable.json"));
            Iterator<?> drops = data.iterator();
            while (drops.hasNext()) {
                JSONObject drop = (JSONObject) drops.next();
                final int npcId = ((Long) drop.get("npc_id")).intValue();
                TableGroup group = new TableGroup(npcId);
                for(TablePolicy policy : TablePolicy.POLICIES) {
                    if (!drop.containsKey(policy.name().toLowerCase())) {
                        continue;
                    }
                    JSONObject dropTable = (JSONObject) drop.get(policy.name().toLowerCase());
                    Table table = new Table(policy, ((Long) dropTable.get("accessibility")).intValue());
                    JSONArray tableItems = (JSONArray) dropTable.get("items");
                    Iterator<?> items = tableItems.iterator();

Please note that the last block of information are drops from npc's that have different identification values from the ones commonly in 317's. If you are looking to find out which npc id value is for each npc, I can send you a list. If you have any suggestions on how this can be improved or use this and find a bug, please let me know.
