gameobject-create

GameObject / Create

Create a new GameObject in opened Prefab or in a Scene. If needed - provide proper 'position', 'rotation' and 'scale' to reduce amount of operations.

How to Call

HTTP API (Direct Tool Execution)

Execute this tool directly via the MCP Plugin HTTP API:

curl -X POST http://localhost:50187/api/tools/gameobject-create \
  -H "Content-Type: application/json" \
  -d '{
  "name": "string_value",
  "parentGameObjectRef": "string_value",
  "position": "string_value",
  "rotation": "string_value",
  "scale": "string_value",
  "isLocalSpace": false,
  "primitiveType": "string_value"
}'

With Authorization (if required)

curl -X POST http://localhost:50187/api/tools/gameobject-create \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{
  "name": "string_value",
  "parentGameObjectRef": "string_value",
  "position": "string_value",
  "rotation": "string_value",
  "scale": "string_value",
  "isLocalSpace": false,
  "primitiveType": "string_value"
}'

The token is stored in the file: UserSettings/AI-Game-Developer-Config.json Using the format: "token": "YOUR_TOKEN"

Input

Name	Type	Required	Description
name	string	Yes	Name of the new GameObject.
