Your first fusion
This page walks you from the main menu to playing, in about five minutes.
The main menu¶
Fusion opens on Play:
- Experiences show as covers: a picture, what it is, which games it needs ("You own 1 of 2 games"), and a Play button. Remix opens its cards so you can change it; Share saves it as one file for a friend.
- Your stack (on the right) plays several things together. Add with + Stack, drag them into order, then Play the stack. The top one brings the world, who you play and the ending.
- Sandbox scenarios (below) are plain scenarios with Play, Edit and Share.
- The buttons at the bottom open My Games, Build a Scenario, Content, Settings and Router Studio.
Play something that needs no game¶
Start with a scenario that says No games needed, such as the playground or the cube. They use Fusion's own test game, so they always work.
- Press Play on it.
- A small panel shows each game starting. Fusion starts the games a scenario needs by itself: you don't open them first.
- You're in. Walk around. Esc frees the mouse; press it again to go back to the menu.
Controls¶
| Key | What it does |
|---|---|
| W A S D, mouse | move, look |
| Space / Shift | jump / run |
| E | use a screen in the world (and step back from it) |
| Q (hold) | the spawn menu (in plain scenarios: The sandbox) |
| C | the context menu: click anything, from any game, to change it |
| 1 2 3 4 | tools: Grab, Spawner, Remover, Weld |
| V | fly (noclip) |
| F5 | Devices: place timers, triggers, score counters (Devices) |
| F6 | the cost meter: how much each game uses |
| F7 / F8 | see the shared collision / every creature and prop Fusion knows |
| F9 | measure performance (start, then stop) |
| Esc | free the mouse; again: back to the menu |
An Experience can turn some of these off: it decides what you may do.
Play with one of your games¶
- Open My Games. Fusion lists the games it found on your PC and what each needs.
- A game that says Needs setup gets one-click setup: Fusion installs what it needs into the game, keeping a list so Undo setup puts it back exactly as it was.
- A game that says Not supported yet has no router on your PC. If the content hub has one, you'll see Community routers (N): press it and Install.
- Back in the menu, scenarios that use that game are now playable.
When something doesn't start¶
Fusion keeps running even if a game doesn't. It says what went wrong in plain words ("VEIN stopped", "close the game first"). Fixing problems lists the common ones.
