Installation

Follow the steps in order.

  1. Join the Prova Group

    You must be in the Prova group when you buy and when you sign in to your dashboard. Players in your game don’t need to join.

  2. Buy the Game Pass

    One payment in Robux, from the Staff System Messages page. The Game Pass is your proof of purchase.

    Then open your dashboard and create your licence key. It is shown once, so copy it somewhere safe. One key covers every system you own, in up to six of your experiences.

  3. Download the Staff System Messages File

    The Staff System Messages arrives as one file, from the Prova Discord server. Save it somewhere you can find it.

  4. Install Prova Core

    Once per experience, however many Prova systems you own. Core is free. Open View → Explorer and click the arrow beside ReplicatedStorage. If PROVA | Core is already there, skip this step.

    1. Download Prova Core from the Prova Discord server.
    2. In Explorer, right-click Workspace and choose Insert from File. Pick the Prova Core file.
    3. Among what it adds are two folders named PROVA | Core.
    4. Drag the one holding Constants, Core, Ed25519 and Log into ReplicatedStorage.
    5. Drag the one holding CoreServer and LicenseProvider into ServerScriptService.
    6. Delete anything left over, such as an empty model.
    Explorer

    ReplicatedStorage

    └─ PROVA | Core

    ServerScriptService

    └─ PROVA | Core

    Only one copy of Core. A second PROVA | Core stops every system with PC-002.

  5. Add the Staff System Messages Folders

    In Explorer, right-click Workspace and choose Insert from File. Pick the Staff System Messages file. Among what it adds are three objects named PROVA | Staff System Messages. Drag each one into its service.

    Drag thisInto

    The ScreenGui holding Messages and OpenButtonStarterGui
    Remove any older staff message scripts and windows. Delete anything left over, such as an empty model.

  6. Check Your Chat

    In Explorer, click TextChatService. In Properties, ChatVersion must say TextChatService. If it says LegacyChatService, change it.

    Explorer/TextChatService/Properties/ChatVersion

  7. Set Your Group and Write Your Messages

    Open MessagesConfig. Until GroupId is set, nobody can send.

    Read Roblox’s rules below before writing a message.

    ServerScriptService/PROVA | Staff System Messages/MessagesConfig
    1. GroupId: change 0 to your group’s ID, the number in its web address.
    2. MinimumRank: the lowest rank that can send.
    3. Topics: your topics and messages. 12 messages at most, in total.

  8. Turn On Allow HTTP Requests

    Turn on Allow HTTP Requests and click Save. Without it the licence can’t be checked and Core stops with PC-004. Already on if another Prova system works in this game.

    File/Experience Settings/Security

  9. Add Your Licence Key as a Secret

    Publish your game first: File → Publish to Roblox. Then, in a web browser, open create.roblox.com, click your experience, and in the left menu choose Secrets → Create Secret. Fill in all three fields exactly.

    Already done for another Prova system? Skip this step. Lost your key? Rotate it on your dashboard and paste the new one here.

    Creator Dashboard/Your Experience/Secrets/Create Secret
    Add Your Licence Key as a Secret
    FieldType
    Nameprova_licence
    SecretYour licence key
    Domainapi.withprova.app

  10. Publish and Check the Output

    Publish and join your game. Press F9 to open the Developer Console and choose the Server log. When the Staff System Messages works, you see these lines.

    In the game, join with a staff account. A button appears on the left. Click it, pick a topic and press a message. It appears in chat for every player, starting [System preset].

    Testing in Studio instead? Open View → Output. A normal Play can’t read the published secret, so add a Local Secret named prova_licence with your key under File → Experience Settings → Security, or use a Team Test.

    Output

    [PROVA | Core] v0.2.0 starting.

    [PROVA | Core] Staff System Messages v1.0.0 registered.

    [PROVA | Staff System Messages] v1.0.0 ready. 6 presets in 3 topics.

    [PROVA | Core] Licence confirmed.

Roblox’s Preset Rules.

Staff messages are presets under Roblox’s Preset system guidelines. The system already does these for you. Breaking the rules can get the feature disabled, or action taken against your game, account or group.

01

12 messages

At most 12 in your whole game. Extra ones are ignored, with a warning.

02

10 seconds

At least 10 seconds between one staff member’s sends.

03

Labelled

Every message starts [System preset], in its own colour, with no name or bubble.

04

Filtered

Roblox’s text filter checks every message, and punctuation at the end is removed.

What You Can Write.

The system can’t check what your messages say. Keep them about running your game.

Good

  • The cafe is now open
  • Restock needed at the counter
  • A training session starts soon
  • Thanks for visiting

Not allowed

  • Anything that imitates a conversation or normal chat
  • Questions and answers, like How are you, Yes, No
  • Compliments or personal questions not about the game
  • Letters, numbers or codes that spell out other messages
  • Anything meant to get around Roblox’s chat restrictions

Settings

All settings are in one file. Change a value, then publish.

Notes

The 12 messages are for your whole game. If another system in your game also has presets, together they must stay at 12 or fewer.
Your own button can open the window for staff: add a boolean attribute named OpensStaffMessages to it, ticked.
