Changing the starting state of the world
When you deploy a SpatialOS project, the initial state of the SpatialOS world is defined by a
snapshot. The example projects come with a default snapshot
snapshots/default.snapshot - but you can modify it or create new ones.
In the Unreal Starter Project, there’s an Unreal commandlet to generate a snapshot, located
The commandlet uses the C++ worker API.
The commandlet creates a spawner entity that will exist in the world when the game starts. You can add your own entities by using the SpatialOS components and Unreal blueprints you defined. When you’re happy with your changes, build your new snapshot:
- Compile your C++ changes.
- On the root of your project run
./generatesnapshot.sh(this will run the Unreal commandlet and overwrite
Once your new snapshot is built, you can launch your new world with
spatial local launch --snapshot=<your_snapshot_name>.snapshot.
