Direct answer: To call a moderator in Submarine Roleplay 2 (Roblox) you should use the game’s built-in “call mod” / report interface or follow the server’s instructions (Discord or in‑game staff list) — if the game has a mod-call button, open the report/mod menu, enter the offender and reason, then submit; mods receive the ticket and can join the server to help.

How to do it step‑by‑step

  • Open the in-game menu or the UI element labeled Report / Mod Call / Request Mod.
  • Select the player you’re reporting (or type their name) and choose a reason (harassment, exploiting, griefing, etc.).
  • Submit the ticket; the system usually enforces a cooldown (often ~60 seconds) to prevent spam.
  • If the game supports it, moderators will see the request and may have a “join server” or teleport button to come to your server; click any provided “join” or “teleport” option only if you are staff.

Alternatives if the in-game UI isn’t present

  • Check the experience description or the developer’s Discord for rules and the staff contact method — many roleplay games list mod contact or webhook/report channels there.
  • If you can’t find an in-game mod-call system, look for a support/commands chat feature (some games let players type commands like !modcall followed by a name) — this is community-created in some places and requires the server to have that script installed.

If you’re a developer wanting to add a mod-call system

  • Use an existing mod-call model or tutorial (several community models/tutorials show how to add a mod-call system with RemoteEvents, a moderator list, and optional Discord webhooks). Follow the model’s setup steps: place scripts into ReplicatedStorage / ServerScriptService / StarterGui, add moderator user IDs, and configure webhooks if you want Discord notifications.
  • Common features to include: moderator whitelist (user IDs), a cooldown per player, a UI to submit reports (player + reason), server‑to‑server notification (so mods in other servers see reports), and a join/teleport button for mods. Many tutorials include ready-made models you can insert into Roblox Studio and adapt.

Safety and etiquette

  • Only call a mod for genuine rule breaches; misuse can slow down help for real issues and may trigger rate limits or sanctions.
  • Provide clear details (what happened, time, player names, screenshots or timestamps if possible) so staff can act quickly.

Quick troubleshooting

  • If the button does nothing in Studio, that’s expected — join a live server to test join/teleport features.
  • If mod calls aren’t reaching staff, check whether the game requires joining the developer’s Discord or whether moderators’ user IDs were set in the modcall script/module.

Example (short)

  • Open Report UI → select player “Offender123” → choose “exploiting” → submit → wait for mod to respond or appear via the join button (60s cooldown between calls).
