 3 | # Terraria Per Player Loot
 4 | A [TShock](https://github.com/Pryaxis/TShock) server plugin which makes
 5 | naturally spawned loot chests have a separate inventory for each player on your
 6 | server. Every player that finds a chest can loot it for themselves, even if it
 7 | has been looted by someone else before.
 8 | 
 9 | ## The Problem
10 | Terraria multiplayer has one big issue - the world you play on is finite, and
11 | there are only so many items and resources to go around. 
12 | 
13 | When you start a new world to play on with your friends, the few people who
14 | choose to go surface exploring or caving are likely to find most of the chests,
15 | and, as a result, most of the early game loot.
16 | 
17 | This is not a problem with bosses in Expert or Master mode, because they drop a
18 | loot bag for each player that damaged them, and everyone can be happy.
19 | 
20 | This plugin makes it much more viable to run large Terraria multiplayer servers,
21 | as there is always an incentive for exploring and caving - the loot is still
22 | there for you to find!
23 | 
24 | ## Installation
25 | 1. Copy `PerPlayerLoot.dll` into the `ServerPlugins` directory of your TShock
26 |    server. You can download this from the [GitHub Releases](https://github.com/xxcodianxx/PerPlayerLoot/releases/) of this repository.
27 | 3. Start a new world from scratch (yes, this is important, read below) and play!
28 | 
29 | > [!WARNING]
30 | > If migrating from version `1.0` of the plugin, you need to move `perplayerloot.sqlite`
31 | > from the server root directory to the `tshock` folder. You should see the file as `tshock/perplayerloot.sqlite`.
32 | > If you do not do this, your existing world chests will behave like loot chests!
33 | 
34 | ## How it Works
35 | This plugin aims to not modify the server-side chest state
36 | (`Terraria.Main.chest`) on chest interactions, in the hope that it can be as
37 | least destructive to world save data as possible. 
38 | 
39 | It works by intercepting the `ChestPlace`, `ChestOpen` and `ChestItem`
40 | packets and spoofing the contents of a loot chest by sending carefully crafted
41 | `ChestItem` packets from an internal database. 
42 | 
43 | The per-player loot data is written on disk to the SQLite file
44 | `perplayerloot.sqlite` on every world save, alongside a list of all
45 | player-placed chest X and Y coordinates. **If your player-placed chests are not
46 | in this exclusion list, they will be treated as world-generated loot chests.**
47 | 
48 | This means that In order for player-placed chests to be unaffected, **you need
49 | to have the plugin installed from the very beginning of your server.** If you
50 | install it halfway through a playthrough, all chests in the world will be
51 | treated as if they were generated and will duplicate their inventory contents
52 | for each player.
53 | 
54 | The only time when the `Main.chest` array is modified is when a loot chest is
55 | possibly broken (which should rarely happen). In that case, the real chest in
56 | `Main.chest` has its items zeroed.
57 | 
58 | ## Debug Commands
59 | - `/ppltoggle` - Toggle the plugin packet hooks globally. **WARNING:** using
60 |   this command is unsupported and can lead to desynchronization of the
61 |   `Main.chest` array and the internal plugin state. 
62 |   
63 |   Debug use only! When in a disabled state, any chests you place will become
64 |   loot chests, and any chest inventory accessed will be its **real inventory**,
65 |   not a per-player instanced one!
