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.
