Basic Store Plugin

[codename_B]

Here's the store plugin I've been working on, I finally got the ini file writing to work.

The basics - credits are earned by mining, one credit per block mined, doesn't matter the type. When a method to detect playerkills is added, I will be adding in 100 credits for killing a player and losing 100 credits for being killed. When mobs and monsters are implemented, I will be adding a credit value system to that too

You can buy:
64 torches - 64 credits
wood shovel, axe, pickaxe, sword - 0 credits (new players joining the server automatically get access to basic tools)
stone shovel, axe, pickaxe, sword - 100 credits
iron shovel, axe, pickaxe, sword - 500 credits
gold shovel, axe, pickaxe, sword - 800 credits
diamond shovel, axe, pickaxe, sword - 1000 credits

This is easily expandable to include other items as I've added a fairly easy to expand store api with a function to check and see if I player can afford an item

Before I forget, you can access the prices list by typing "/store" into the chat window.

That should be all else you need

Thats pretty cool im working on something similar for my rpg server, one thing that i would say though is that you're using commands for each itemset which bugs me, i dont know about anyone else im just wierd, but what im doing in mine is using Split
so like

Code:

function storecommand(Split, Player)
if(Split[2]=="buy") then
-- do stuff
end
end

but its a nice plugin, more than i've got so far

[codename_B]

I considered doing that, but then I'd have to add in a function to detect each type and serve accordingly, and in the end I worked out for what I was doing I would end up having to write more lines of code for that

Thanks for the feedback though!

[Tybor]

For optimisation, you only need to IniFile:ReadFile() on plugin loading and IniFile:WriteFile() on server shutdown.

Class IniFile itself is maintained in RAM.

[FakeTruth]

Yeah, if you create the cIniFile in a global scope (global variable) you only have to read it once.

[codename_B]

Ah thanks

These things you learn as you go.

[DrkCodeman]

What am I doing wrong? I have enabled this in settings.ini and created a directory called "Store" with the LUA in that directory I've even create score.ini in that same directory as the LUA. This is what I get when I launch the server:

[19:17:05] LUA: Plugins/Store/Kit.lua:7: attempt to index global 'Lua__cPlugin' (a nil value)
[19:17:05] Error in plugin Plugins/Store in file Plugins/Store/Kit.lua

[NiLSPACE]

You did nothing wrong. Its becouse this plugin is outdated.

[xoft]

This plugin is extremely outdated and won't work with current MCServer versions; it needs to be properly updated and maybe altogether revised.

[DrkCodeman]

Aww, and I really wanted a store plugin
