rustic.edit_object_attribute()
Compatibility
Supported languages: C, C++, C#, Python, JavaScript, Lua 5.4, Luau, Java, PHP and HTML/inline JavaScript (binding spellings and return shapes differ).
Use a compatible native engine build and the language tools required by your binding. This does not establish browser/mobile export or release qualification for every OS.
The signature below is the shared reference notation; language examples show the actual binding syntax. Question marks mark optional arguments and explicit defaults are shown where recorded. Do not copy reference notation as a typed declaration.
See Feature status and compatibility for API 1.0/1.1 and per-method restrictions. Engine release tags and Docs v0.1 are independent versions.
Signature
rustic.edit_object_attribute(source, name, value)
Setup and usage
Use attributes for built-in entity state. Prefer set_translation for Position and set_enabled for Enabled when those dedicated calls better express intent.
Parameters
| Variable | Type | Required | Description |
|---|---|---|---|
source | string | Yes | Stable entity ID or full rustic.game.Scene.Root.Child path for object helpers. |
name | string | Yes | Name, Position, Size, Color (RGB), CanTouch, CanCollide, Anchored, or Parent. |
value | attribute-specific | Yes | Value matching the attribute type. |
Return and timing
Get returns the current value. Edit validates a typed mutation; write timing depends on the runtime.
Execution behavior
Core write timing differs between immediate Lua host calls, deferred JavaScript/Web commands and external SDK query flushes. Scheduled actions advance with the scene clock; synchronous queries evaluate at the call. Follow execution rules and the return/timing notes for this category.
Language examples
Use these snippets inside Start/on_start after generating the Programming Workspace and attaching the script. Python imports rustic, Game and instance from rustic; C++ includes rustic.hpp; C includes rustic.h; C# uses using static Rustic; Java runs inside a Rustic subclass; PHP declares global $rustic, $Game, $instance in its callback. HTML uses an inline script in a ui/ asset. See Lifecycle callbacks for complete registration examples. Public-property examples require a declared integer health property. Scene examples require the named objects to exist before Play.

- In Play, unanchored built-in primitives fall under gravity; CanCollide enables solid box response only when both objects enable it. Anchored prevents physics movement and clears velocity on the next fixed tick. CanTouch does not affect solids; no collision or touch callbacks are emitted. Imported meshes do not simulate yet. See the Basic physics guide for setup and limits. Unknown attributes and type changes are rejected. Parent accepts a stable entity ID or null. Target another object with rustic.game.Scene.Root.Child:EditAttribute in Lua, native member calls in JavaScript/Python/C#/PHP, C++ subscripts, or an edit_attribute protocol command containing source. See Edit scene objects for setup, native calls in every language, and runtime limits.
- Every gameplay language calls the engine-owned API. Rustic supplies SDKs and dispatches callbacks; scripts do not parse requests or serialize responses. See the language guide for complete setup and callback registration.
- The direct edit_object_attribute helper is available in embedded Lua and JavaScript (including HTML); other SDKs use the native scene-object call shown above. Only embedded Lua exposes a path-based GetAttribute. For the scene-object example, create a scene named Demo with Room → Player. Change those names to match your scene; see Edit scene objects for full setup.
Errors and debugging
Read the constraints above and the Console diagnostic. Invalid types, non-finite values, stale targets or unavailable native services can fail validation. A failed callback disables the behavior; a failed source reload keeps the last good instance. Exact error messages depend on the language adapter. See Troubleshooting.
