// TEST: node_query_basic
// CATEGORY: unit
// DESCRIPTION: Basic node query operations with get_node() and get_parent()
// EXPECT: success
// ASSERT: Found Player node
// ASSERT: Found UI node
// ASSERT: Got parent node
// ASSERT: Found OtherChild node
// ASSERT: Example Complete
//
// Example: Basic Node Query Operations
// Demonstrates get_node() and get_parent() usage
//
// GODOT SCENE SETUP:
// 1. Create a new 2D Scene
// 2. Add FerrisScriptNode as root, rename to "Main"
// 3. Attach this script to Main node (Inspector → Script Path)
// 4. Add child nodes to Main:
//    - Node2D named "Player"
//    - Node2D named "UI"
//    - Camera2D named "Camera2D"
//    - Node2D named "Enemy"
//    - Node2D named "OtherChild"
//
// Scene Tree Structure:
// /root
//   └─ Main (FerrisScriptNode with this script)
//        ├─ Player
//        ├─ UI
//        ├─ Camera2D
//        ├─ Enemy
//        └─ OtherChild
//
// EXPECTED BEHAVIOR:
// - Script loads successfully
// - _ready() executes without errors
// - All node queries succeed (nodes found)
// - Console shows success markers (✓)

fn _ready() {
    print("=== Basic Node Query Operations ===");
    
    // Get a child node by relative path
    let player = get_node("Player");
    print("✓ Found Player node");
    
    // Get a node by child path
    let ui = get_node("UI");
    print("✓ Found UI node");
    
    // Get parent of this node
    let parent = get_parent();
    print("✓ Got parent node");
    
    // Access sibling node
    // Note: Method chaining like get_parent().get_node() not yet supported
    // Use direct path or has_node validation instead
    let sibling = get_node("OtherChild");
    print("✓ Found OtherChild node");
    
    print("=== Example Complete ===");
}

fn _process(delta: f32) {
    // Note: This runs every frame, avoid logging here in real usage
    // For testing, we just access nodes silently
    let target = get_node("Enemy");
    let camera = get_node("Camera2D");
