How to use Functions

Summary

Functionality is split up into: Variables, Functions, Properties, Methods, and Events.

Variable - A variable, that can be read and/or written to without () brackets, which is either global or in a namespace.
Function - A function, that can be called, which is either global or in a namespace.
Property - An OOP property, that can be read and/or written to without () brackets, which is used on an object.
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 Player inherits type Ped, meaning that type Player has 100% of the functionality that Ped has.

Examples

Lua, Client-Side, Variable:

if debugMode then -- debugMode is a variable
    message('Debug mode is enabled for you!', COLOUR_GREEN)
end

Lua, Server-Side, Function:

message('This message will be shown in the chat box!', COLOUR_GREEN) -- message is a function

Lua, Server-Side, Property:

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:

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)
