Play-in-editor
Run your game inside the editor, without making a separate build.
Play, pause, stop
The Play, Pause and Stop buttons are near the right end of the toolbar.
Play saves your project first, and Stop restores that saved state, so changes made while playing are discarded. A project that's never been saved asks you to save it before playing.
Ghost Mode (in the gear menu) gives you a free camera while playing. Move it with W A S D, Space and Ctrl.
Network modes
Pick a mode from the arrow next to Play. The option you select will be saved as the default play mode for next time.
| Mode | Play button action |
|---|---|
| Play Local | The game runs in the editor in single player |
| Play as Client | The editor connects to the server at Host:Port. Start the server first, separately; see Running a server. |
| Play as Dedicated Server | The editor hosts the game on Port. It has no player of its own; players spawn for clients that connect. |
Stop disconnects or stops hosting.
The same menu has Play in Web Browser, which builds the game for the web and opens it in your browser. See Web.
Nothing is replicated unless the game's world has the IsReplicated flag. It's part of the world's default flags, so a world saved with Flags = Default has it.
But it is something to look into if you're having issues in this area. On your filesystem, open your project's Content/Worlds/MainWorld.hmf file and look at its Flags.

When the editor plays as a dedicated server, run the game against it to add players, syncing content from the editor's cache server:
