Set Up PC and Mobile Crossplay on a Terraria Server

Overview

A standard Terraria server does not allow PC and mobile players to join the same world together. That is inconvenient when your group is split between platforms, and nobody wants the server invite to turn into a platform debate.

To make PC and mobile crossplay work, the server needs to run TShock and load a crossplay plugin. The process is mostly changing the server version, uploading one plugin file, and restarting cleanly.

Install TShock

1. Open your HolyHosting server panel and stop the Terraria server.
2. Find the version selector in your panel.
3. Choose the Terraria TShock version from the dropdown.

1. Confirm the version change when prompted. If the panel asks whether to generate a new world, choose the option that fits your setup.
2. Start the server again so TShock can create its folders and finish loading.

Add the Crossplay Plugin

1. Go to the Crossplay plugin GitHub page and download the latest `Crossplay.dll` release file.

1. Return to your server panel.
2. Open your FTP client and log in.
3. Find the `ServerPlugins` folder and open it.

1. Use the upload option, then drag `Crossplay.dll` into the plugin folder.

1. Wait until the upload reaches 100 percent.
2. Return to the main server controls and restart the server.

After the restart, PC and mobile Terraria clients should be able to connect to the same server.

Troubleshooting

The ServerPlugins folder is missing

This usually means TShock has not fully started yet. Confirm the server is set to Terraria TShock, restart it, then wait a minute before checking FTP again. If the folder still does not appear, review the console for startup errors. You can also create the `ServerPlugins` folder manually if needed.

Crossplay still does not work

First, confirm the server is still running TShock. Next, check that `Crossplay.dll` is inside `ServerPlugins`, not the root directory or another folder. Restart the server after confirming the file location. If the problem continues, check the Crossplay GitHub page for a newer plugin release that matches your Terraria version.
