ProjectManifest

Since 0.6Changed in 0.7

argus.project.json: versioned project settings, separate from any scene.

Fields

Field	Type	Required	Description
`schemaVersion`	`number`	yes	Manifest schema version. Not the application version and not the engine version.
`projectId`	`string`	yes	Stable project identity: a lowercase RFC 9562 UUID, generated once, never derived from a name.
`engineVersion`	`string`	no	The engine series that opens this project, `major.minor` such as `0.5`: which installed engine the Talos Launcher starts it with (docs/PLAN-LAUNCHER.md). Not a compatibility claim, and no engine reads it. Absent: the newest installed engine.
`savedWith`	`string`	no	The engine version that last wrote this file, `major.minor.patch` such as `0.5.2`; the engine sets it when it saves the manifest. The launcher reads it to warn before an older engine is chosen and to offer an upgrade. Not a compatibility claim, and it never changes how the project loads. Absent: not saved by an engine that records it.
`kind`	`string`	no	What sort of game the project is: `3d` (the default when absent) or `2d`. A 2D project draws through the same renderer. The kind drives the editor (its 2D viewport and tools); it does not change how a scene runs, so a 2D scene sets its own orthographic camera and planar bodies. Changing it never rewrites scenes. Independent of render.profile.
`application`	`ProjectApplication`	yes
`startupScene`	`string`	yes	Project-relative path to the scene the game starts in. Must exist and validate as a scene.
`window`	`ProjectWindow`	no
`export`	`ProjectExport`	no	Export settings shared by every platform (the store app id). Absent: every export setting takes its default.
`settings`	`ProjectSettings`	no
`render`	`ProjectRender`	no
`physics`	`ProjectPhysics`	no
`graphics`	`ProjectGraphics`	no
`input`	`SceneInput`	no	Input contexts and actions every scene has, in a scene's meta.input shape. A scene's context of the same name merges action by action, and its action replaces the project's.
`audio`	`ProjectAudio`	no
`assets`	`ProjectAssets`	no	Asset generation for this project: off by default; providers, style, budgets and spend.
`layers`	`LayerDef[]`	no	The project's layers, in bit order, at most 32: what collides with what, and what each camera draws. The first is "default". Entities name one with `layer`. Absent: the one layer "default".
`experimental`	`string[]`	no	The Experimental features this project opts into, as ids from the engine's feature list: a part (`water/waterfall`) or a whole package (`water`). Experimental features may change or be removed, with no compatibility promise; a game that uses one without opting in is warned at export. Absent: none.
