🎯 Common Patterns

RSG Framework Patterns

These are the most common patterns you’ll use when developing for RSG Framework. Master these and you’ll write better, more reliable code!

Pattern 1: Get Core Object

Every RSG resource starts with this:

-- CLIENT or SERVER SIDE
local RSGCore = exports['rsg-core']:GetCoreObject()

Always use local when getting the core object to avoid conflicts!

Complete Example:

-- CLIENT SIDE
local RSGCore = exports['rsg-core']:GetCoreObject()

-- Wait for player to load
RegisterNetEvent('RSGCore:Client:OnPlayerLoaded', function()
    local PlayerData = RSGCore.Functions.GetPlayerData()
    print('Player loaded:', PlayerData.charinfo.firstname)
end)

Pattern 2: Player Validation (Server)

Always validate the player exists before doing operations:

-- SERVER SIDE
RegisterNetEvent('myresource:server:doSomething', function()
    local src = source
    local Player = RSGCore.Functions.GetPlayer(src)

    -- ALWAYS check if Player exists
    if not Player then return end

    -- Now safe to use Player
    local money = Player.Functions.GetMoney('cash')
end)

Complete Example with Multiple Checks:

-- SERVER SIDE
RegisterNetEvent('shop:server:buyItem', function(itemName, amount)
    local src = source
    local Player = RSGCore.Functions.GetPlayer(src)
    if not Player then return end

    -- Check item exists
    local item = RSGCore.Shared.Items[itemName]
    if not item then
        lib.notify(src, {description = 'Invalid item', type = 'error'})
        return
    end

    -- Check amount is valid
    if type(amount) ~= 'number' or amount < 1 or amount > 100 then
        lib.notify(src, {description = 'Invalid amount', type = 'error'})
        return
    end

    -- Check player has money
    local price = (item.price or 0) * amount
    if Player.Functions.GetMoney('cash') < price then
        lib.notify(src, {description = 'Not enough money', type = 'error'})
        return
    end

    -- All checks passed, process purchase
    Player.Functions.RemoveMoney('cash', price, 'shop-purchase')
    exports['rsg-inventory']:AddItem(src, itemName, amount, nil, nil, 'shop-purchase')

    lib.notify(src, {
        description = 'Purchased ' .. amount .. 'x ' .. item.label,
        type = 'success'
    })
end)

Pattern 3: Inventory Operations

Adding Items (Server)

-- SERVER SIDE
local Player = RSGCore.Functions.GetPlayer(source)
if not Player then return end

-- Always check if player can receive item
local canAdd = exports['rsg-inventory']:CanAddItem(source, 'bread', 5)

if canAdd then
    exports['rsg-inventory']:AddItem(source, 'bread', 5, nil, nil, 'crafted')
    lib.notify(source, {description = 'Crafted 5 bread', type = 'success'})
else
    lib.notify(source, {description = 'Inventory full!', type = 'error'})
end

Removing Items (Server)

-- SERVER SIDE
local Player = RSGCore.Functions.GetPlayer(source)
if not Player then return end

-- Check if player has item
if exports['rsg-inventory']:HasItem(source, 'wood', 10) then
    exports['rsg-inventory']:RemoveItem(source, 'wood', 10, nil, 'crafting')
    lib.notify(source, {description = 'Used 10 wood', type = 'success'})
else
    lib.notify(source, {description = 'Not enough wood', type = 'error'})
end

Checking Items (Server)

-- SERVER SIDE
-- Check single item
local hasBread = exports['rsg-inventory']:HasItem(source, 'bread', 5)

-- Check multiple items (all required)
local hasItems = exports['rsg-inventory']:HasItem(source, {
    bread = 2,
    water = 1
})

-- Check item count
local breadCount = exports['rsg-inventory']:GetItemCount(source, 'bread')

Pattern 4: Money Operations (Server)

-- SERVER SIDE
local Player = RSGCore.Functions.GetPlayer(source)
if not Player then return end

-- Get money
local cash = Player.Functions.GetMoney('cash')
local bank = Player.Functions.GetMoney('bank')

-- Add money
Player.Functions.AddMoney('cash', 100, 'job-payment')

-- Remove money (with check)
if Player.Functions.GetMoney('cash') >= 50 then
    Player.Functions.RemoveMoney('cash', 50, 'purchase')
else
    lib.notify(source, {description = 'Not enough money', type = 'error'})
end

-- Set money (use sparingly)
Player.Functions.SetMoney('bank', 1000, 'admin-set')

Complete Payment Example:

-- SERVER SIDE
RegisterNetEvent('job:server:completeTask', function()
    local src = source
    local Player = RSGCore.Functions.GetPlayer(src)
    if not Player then return end

    local payment = 150

    -- Pay player
    Player.Functions.AddMoney('cash', payment, 'task-completed')

    lib.notify(src, {
        description = 'Task completed! Earned $' .. payment,
        type = 'success'
    })
end)

Pattern 5: Job/Gang Checks

Check Player’s Job (Server)

-- SERVER SIDE
local Player = RSGCore.Functions.GetPlayer(source)
if not Player then return end

local job = Player.PlayerData.job

-- Check job name
if job.name == 'police' then
    print('Player is police')
end

-- Check job grade
if job.name == 'police' and job.grade.level >= 3 then
    print('Player is high rank police')
end

-- Check if on duty
if job.onduty then
    print('Player is on duty')
end

Check Player’s Job (Client)

-- CLIENT SIDE
local RSGCore = exports['rsg-core']:GetCoreObject()
local PlayerData = RSGCore.Functions.GetPlayerData()

if PlayerData.job and PlayerData.job.name == 'doctor' then
    print('You are a doctor')
end

-- Listen for job updates
RegisterNetEvent('RSGCore:Client:OnJobUpdate', function(job)
    print('Job changed to:', job.label)
end)

Complete Job-Restricted Example:

-- SERVER SIDE
RegisterNetEvent('police:server:handcuff', function(targetId)
    local src = source
    local Player = RSGCore.Functions.GetPlayer(src)
    if not Player then return end

    -- Check if player is police
    if Player.PlayerData.job.name ~= 'police' then
        lib.notify(src, {description = 'You are not police!', type = 'error'})
        return
    end

    -- Check if on duty
    if not Player.PlayerData.job.onduty then
        lib.notify(src, {description = 'You must be on duty!', type = 'error'})
        return
    end

    -- Process handcuff
    TriggerClientEvent('police:client:getHandcuffed', targetId, src)
end)

Pattern 6: Notifications

Using ox_lib notify (modern way):

-- CLIENT or SERVER SIDE

-- Success notification
lib.notify({
    description = 'Action completed successfully!',
    type = 'success'
})

-- Error notification
lib.notify({
    description = 'Something went wrong!',
    type = 'error'
})

-- Info notification
lib.notify({
    description = 'Here is some information',
    type = 'info'
})

-- Warning notification
lib.notify({
    description = 'Be careful!',
    type = 'warning'
})

-- Custom duration
lib.notify({
    description = 'This shows for 10 seconds',
    type = 'info',
    duration = 10000
})

-- With title
lib.notify({
    title = 'Police Department',
    description = 'Backup requested',
    type = 'info'
})

On Server (send to client):

-- SERVER SIDE
lib.notify(source, {
    description = 'Transaction completed',
    type = 'success'
})

Pattern 7: Distance Checks

Client-Side Distance Check

-- CLIENT SIDE
CreateThread(function()
    local targetCoords = vector3(2633.0, -1220.0, 53.0)

    while true do
        local playerPed = PlayerPedId()
        local playerCoords = GetEntityCoords(playerPed)
        local distance = #(playerCoords - targetCoords)

        if distance < 2.0 then
            -- Player is close
            lib.showTextUI('[E] Interact')

            if IsControlJustPressed(0, RSGCore.Shared.Keybinds['E']) then
                TriggerEvent('interact:action')
            end
        else
            lib.hideTextUI()
        end

        Wait(distance < 10.0 and 0 or 1000)
    end
end)

Server-Side Distance Check

-- SERVER SIDE
local function isPlayerNear(source, coords, maxDistance)
    local ped = GetPlayerPed(source)
    local playerCoords = GetEntityCoords(ped)
    local distance = #(playerCoords - coords)

    return distance <= maxDistance
end

-- Usage
RegisterNetEvent('shop:server:interact', function()
    local src = source
    local shopCoords = vector3(2633.0, -1220.0, 53.0)

    if not isPlayerNear(src, shopCoords, 5.0) then
        lib.notify(src, {description = 'Too far from shop!', type = 'error'})
        return
    end

    -- Player is close enough
    -- ... open shop
end)

Pattern 8: Useable Items

-- SERVER SIDE
local RSGCore = exports['rsg-core']:GetCoreObject()

RSGCore.Functions.CreateUseableItem('bread', function(source, item)
    local Player = RSGCore.Functions.GetPlayer(source)
    if not Player then return end

    -- Remove item
    if exports['rsg-inventory']:RemoveItem(source, 'bread', 1, item.slot, 'consumed') then
        -- Restore hunger
        Player.Functions.SetMetaData('hunger', math.min(100, Player.PlayerData.metadata.hunger + 25))

        lib.notify(source, {
            description = 'You ate bread',
            type = 'success'
        })

        -- Trigger client animation
        TriggerClientEvent('player:client:playEatAnimation', source)
    end
end)

With Animation (Client):

-- CLIENT SIDE
RegisterNetEvent('player:client:playEatAnimation', function()
    local ped = PlayerPedId()

    lib.requestAnimDict('mech_inventory@eating@multi_bite@wedge_sandwich')

    TaskPlayAnim(ped, 'mech_inventory@eating@multi_bite@wedge_sandwich', 'eat_wedge_sandwich', 8.0, 8.0, 3000, 0, 0, true, true, true)

    Wait(3000)

    ClearPedTasks(ped)
    RemoveAnimDict('mech_inventory@eating@multi_bite@wedge_sandwich')
end)

Pattern 9: Commands

Basic Command

-- SERVER SIDE
RSGCore.Commands.Add('heal', 'Heal yourself', {}, false, function(source, args)
    local Player = RSGCore.Functions.GetPlayer(source)
    if not Player then return end

    local ped = GetPlayerPed(source)
    SetEntityHealth(ped, 200)

    lib.notify(source, {
        description = 'You have been healed',
        type = 'success'
    })
end)

Command with Arguments

-- SERVER SIDE
RSGCore.Commands.Add('givemoney', 'Give money to player', {
    {name = 'id', help = 'Player ID'},
    {name = 'amount', help = 'Amount of money'}
}, true, function(source, args)
    local src = source
    local Player = RSGCore.Functions.GetPlayer(src)
    if not Player then return end

    local targetId = tonumber(args[1])
    local amount = tonumber(args[2])

    if not targetId or not amount then
        lib.notify(src, {description = 'Invalid arguments', type = 'error'})
        return
    end

    local Target = RSGCore.Functions.GetPlayer(targetId)
    if not Target then
        lib.notify(src, {description = 'Player not found', type = 'error'})
        return
    end

    -- Check if player has money
    if Player.Functions.GetMoney('cash') < amount then
        lib.notify(src, {description = 'Not enough money', type = 'error'})
        return
    end

    -- Transfer money
    Player.Functions.RemoveMoney('cash', amount, 'money-transfer')
    Target.Functions.AddMoney('cash', amount, 'money-transfer')

    lib.notify(src, {description = 'Sent $' .. amount, type = 'success'})
    lib.notify(targetId, {description = 'Received $' .. amount, type = 'success'})
end, 'user')

Admin Command

-- SERVER SIDE
RSGCore.Commands.Add('giveitem', 'Give item to player', {
    {name = 'id', help = 'Player ID'},
    {name = 'item', help = 'Item name'},
    {name = 'amount', help = 'Amount (optional)'}
}, true, function(source, args)
    local targetId = tonumber(args[1])
    local itemName = args[2]
    local amount = tonumber(args[3]) or 1

    local Target = RSGCore.Functions.GetPlayer(targetId)
    if not Target then return end

    exports['rsg-inventory']:AddItem(targetId, itemName, amount, nil, nil, 'admin-give')

    lib.notify(source, {
        description = 'Gave ' .. amount .. 'x ' .. itemName,
        type = 'success'
    })
end, 'admin')

Pattern 10: ox_lib Input Dialogs

Get user input with validation:

-- CLIENT SIDE
local function getPlayerInput()
    local input = lib.inputDialog('Transfer Money', {
        {
            type = 'number',
            label = 'Player ID',
            description = 'Who to send money to',
            required = true,
            min = 1
        },
        {
            type = 'number',
            label = 'Amount',
            description = 'How much to send',
            required = true,
            min = 1,
            max = 10000
        }
    })

    if not input then return end

    local playerId = input[1]
    local amount = input[2]

    TriggerServerEvent('money:server:transfer', playerId, amount)
end

-- Usage
RegisterCommand('sendmoney', function()
    getPlayerInput()
end)

Pattern 11: Progress Bars

Show progress for actions:

-- CLIENT SIDE
local function craftItem()
    if lib.progressBar({
        duration = 5000,
        label = 'Crafting item...',
        useWhileDead = false,
        canCancel = true,
        disable = {
            move = true,
            car = true,
            combat = true
        },
        anim = {
            dict = 'amb_work@world_human_box_pickup@1@male_a@stand_exit_withprop',
            clip = 'exit_front'
        }
    }) then
        -- Completed
        TriggerServerEvent('crafting:server:craftItem', 'wooden_chair')
    else
        -- Cancelled
        lib.notify({description = 'Crafting cancelled', type = 'error'})
    end
end

Pattern 12: Context Menus

Create interactive menus:

-- CLIENT SIDE
local function openJobMenu()
    lib.registerContext({
        id = 'job_menu',
        title = 'Job Actions',
        options = {
            {
                title = 'Clock In/Out',
                description = 'Toggle duty status',
                icon = 'clock',
                onSelect = function()
                    TriggerServerEvent('job:server:toggleDuty')
                end
            },
            {
                title = 'Access Stash',
                description = 'Open job storage',
                icon = 'box',
                onSelect = function()
                    TriggerServerEvent('job:server:openStash')
                end
            },
            {
                title = 'Vehicle Menu',
                description = 'Spawn job vehicles',
                icon = 'car',
                arrow = true,
                onSelect = function()
                    openVehicleMenu()
                end
            }
        }
    })

    lib.showContext('job_menu')
end

-- Usage
RegisterCommand('jobmenu', function()
    openJobMenu()
end)

Pattern 13: Target System (ox_target)

Add interactive zones/entities:

-- CLIENT SIDE
exports.ox_target:addBoxZone({
    coords = vector3(2633.0, -1220.0, 53.0),
    size = vector3(2, 2, 2),
    rotation = 45,
    debug = false,
    options = {
        {
            name = 'open_shop',
            icon = 'fa-solid fa-shop',
            label = 'Open Shop',
            onSelect = function()
                TriggerServerEvent('shop:server:openShop')
            end
        },
        {
            name = 'talk_to_owner',
            icon = 'fa-solid fa-comment',
            label = 'Talk to Owner',
            onSelect = function()
                TriggerEvent('chat:startConversation')
            end
        }
    }
})

Pattern 14: Cleanup on Resource Stop

Always clean up when resource stops:

-- CLIENT SIDE
local activeBlips = {}
local activeObjects = {}

AddEventHandler('onResourceStop', function(resourceName)
    if GetCurrentResourceName() ~= resourceName then return end

    -- Clean up blips
    for _, blip in pairs(activeBlips) do
        if DoesBlipExist(blip) then
            RemoveBlip(blip)
        end
    end

    -- Clean up objects
    for _, object in pairs(activeObjects) do
        if DoesEntityExist(object) then
            DeleteObject(object)
        end
    end

    print('Resource cleaned up')
end)

Summary: Essential Patterns Checklist

Always get RSGCore object with local
Always validate Player exists on server
Always check inventory space before adding items
Always check money/items before removing
Always validate client input on server
Always use appropriate Wait() times in loops
Always clean up on resource stop
