{{DISPLAYTITLE:How to use Functions}}
==Summary==

Functionality is split up into: Variables, Functions, Properties, Methods, and [[HowTo/Events|Events]].

Variable - A variable, that can be read and/or written to without <code>()</code> brackets, which is either global or in a namespace.<br>
Function - A function, that can be called, which is either global or in a namespace.<br>
Property - An OOP property, that can be read and/or written to without <code>()</code> brackets, which is used on an object.<br>
Method - An OOP method, that can be called, which is used on an object.

==Inheritance==

Some types inherit functionality from other types, for example, type <code>Player</code> inherits type <code>Ped</code>, meaning that type <code>Player</code> has 100% of the functionality that <code>Ped</code> has.<br>
Visit the [[Types|Types]] page for a full list of class inheritance.

==Examples==

'''Lua, Client-Side, Variable:'''

{{LuaCode|1=if debugMode then -- debugMode is a variable
    message('Debug mode is enabled for you!', COLOUR_GREEN)
end}}

'''Lua, Server-Side, Function:'''

{{LuaCode|1=message('This message will be shown in the chat box!', COLOUR_GREEN) -- message is a function}}

'''Lua, Server-Side, Property:'''

{{LuaCode|1=addEventHandler('onPlayerJoined', function(event,client)
    message(client.player.name .. ' has joined the server!', COLOUR_GREEN) -- name is a property of type Element (type Player inherits functionality of Element)
end)}}

'''Lua, Server-Side, Method:'''

{{LuaCode|1=addEventHandler('onPlayerJoined', function(event,client)
    client.player:setData('dataKey1', 'dataValue', false) -- setData is a method of type Element (type Player inherits functionality of Element)
end)}}
