uloop execute-dynamic-code

Execute C# code dynamically in Unity Editor.

Usage

uloop execute-dynamic-code --code '<c# code>'

Parameters

Parameter Type Description
--code string C# code to execute (direct statements, no class wrapper)
--compile-only boolean Compile without execution
--auto-qualify-unity-types-once boolean Auto-qualify Unity types

Code Format

Write direct statements only (no classes/namespaces/methods). Return is optional.

// Using directives at top are hoisted
using UnityEngine;
var x = Mathf.PI;
return x;

String Literals (Shell-specific)

Shell Method
bash/zsh/MINGW64/Git Bash 'Debug.Log("Hello!");'
PowerShell 'Debug.Log(""Hello!"");'

Allowed Operations

  • Prefab/material wiring (PrefabUtility)
  • AddComponent + reference wiring (SerializedObject)
  • Scene/hierarchy edits
  • Inspector modifications

Forbidden Operations

  • System.IO.* (File/Directory/Path)
  • AssetDatabase.CreateFolder / file writes
  • Create/edit .cs/.asmdef files

Global Options

Option Description
--project-path <path> Target a specific Unity project (mutually exclusive with --port). Path resolution follows the same rules as cd — absolute paths are used as-is, relative paths are resolved from cwd.
-p, --port <port> Specify Unity TCP port directly (mutually exclusive with --project-path).

Examples

bash / zsh / MINGW64 / Git Bash

uloop execute-dynamic-code --code 'return Selection.activeGameObject?.name;'
uloop execute-dynamic-code --code 'new GameObject("MyObject");'
uloop execute-dynamic-code --code 'UnityEngine.Debug.Log("Hello from CLI!");'

PowerShell

uloop execute-dynamic-code --code 'return Selection.activeGameObject?.name;'
uloop execute-dynamic-code --code 'new GameObject(""MyObject"");'
uloop execute-dynamic-code --code 'UnityEngine.Debug.Log(""Hello from CLI!"");'

Output

Returns JSON with execution result or compile errors.

Notes

For file/directory operations, use terminal commands instead.
