Object Spawning Output

Use this output to spawn arbitrary Node3D objects or scenes dynamically. This is useful for placing buildings, trees, props, or any other game objects generated by your HDA.

Point Attributes

Spawn configuration is specified via point attributes:

Attribute Name	Attribute Type	Attribute Owner	Description
`N`	Vector	Point	Forward direction (positive Z)
`up`	Vector	Point	Up vector
`pscale`	Float	Point	Uniform scale
`scale`	Vector	Point	Non-uniform scale, multiplied by pscale
`hego_spawn`	Int	Point	Required. Set to 1 to enable object spawning
`hego_spawn_type`	Int	Point	0 = spawn registered class, 1 = spawn PackedScene by path
`hego_class_name`	String	Point	Class name when `hego_spawn_type` = 0
`hego_resource_path`	String	Point	Scene resource path when `hego_spawn_type` = 1
`hego_node_path`	String	Point	Spawn path under HEGoNode3D/Outputs. Make unique per point to avoid name conflicts
`hego_custom_properties`	Dictionary	Point	Nested property assignment dictionary using `hego_val` entries

Custom Properties

The hego_custom_properties dictionary allows you to set almost any property on spawned objects in one pass. It must follow a specific format:

Each top-level key is a property name.
The value must be another dictionary containing at least hego_val.
Additional nested keys can define sub-properties for complex value types.

Example Dictionary Format

{
  "shape": {
    "hego_val": "CapsuleShape3D",
    "height": {"hego_val": 0.72},
    "radius": {"hego_val": 0.5}
  }
}

This example creates a CapsuleShape3D, sets its height and radius properties, and assigns it to the target node’s shape property.
