Godot 输入 — 快速参考¶

func _physics_process(delta: float) -> void:
    var input_dir: Vector2 = Input.get_vector(
        &"move_left", &"move_right", &"move_forward", &"move_back"
    )
    if Input.is_action_just_pressed(&"jump"):
        jump()

func _unhandled_input(event: InputEvent) -> void:
    if event is InputEventMouseButton:
        if event.button_index == MOUSE_BUTTON_LEFT and event.pressed:
            handle_click(event.position)
    elif event is InputEventKey:
        if event.keycode == KEY_ESCAPE and event.pressed:
            toggle_pause()

# Mouse/touch and keyboard/gamepad focus are now SEPARATE
# Visual styles may differ depending on which input method is active
# If you have custom focus drawing, test with both input methods

# Standard approach still works:
func _ready() -> void:
    %StartButton.grab_focus()  # Keyboard/gamepad focus

# But be aware: mouse hover focus != keyboard focus in 4.6

# API unchanged, but SDL3 provides:
# - Better device detection across platforms
# - Improved rumble support
# - More consistent button mapping

func _input(event: InputEvent) -> void:
    if event is InputEventJoypadButton:
        if event.button_index == JOY_BUTTON_A and event.pressed:
            confirm_selection()
