Unigine.NodeDummy Class
| Inherits from: | Node |
A dummy node is a zero-sized node that has no visual representation. It is used to organize the other nodes into a hierarchy: the dummy node serves as a parent node and enables to organize the other nodes that are made its children into a group.
Notice
A bounding box of the dummy node is equal to the bounding boxes of all its child nodes combined together.
Creating a Dummy Node#
Create an instance of the NodeDummy class. You can also specify such settings as a name, transformation and so on.
NodeDummyClass.cs
Source code (C#)
using System;
using System.Collections;
using System.Collections.Generic;
using Unigine;
[Component(PropertyGuid = "AUTOGENERATED_GUID")] // <-- this line is generated automatically for a new component
public class NodeDummyClass : Component
{
private void Init()
{
// create a dummy node
NodeDummy dummy = new NodeDummy();
// set a name
dummy.Name = "DummyNode";
}
}Organizing a Nodes Hierarchy#
To organize nodes in a hierarchy, perform as follows:
- Create an instance of the NodeDummy class.
- Create a node and add it as a child to the created dummy node.
NodeDummyClass.cs
Source code (C#)
using System;
using System.Collections;
using System.Collections.Generic;
using Unigine;
[Component(PropertyGuid = "AUTOGENERATED_GUID")] // <-- this line is generated automatically for a new component
public class NodeDummyClass : Component
{
private void Init()
{
// create a dummy node
NodeDummy root = new NodeDummy();
// set a name for the node
root.Name = "root";
// create child nodes
for (int y = -10; y <= 10; y++)
{
for (int x = -10; x <= 10; x++)
{
// create a node (an instance of the ObjectMeshStatic class from the specified mesh-file)
ObjectMeshStatic node = new ObjectMeshStatic("core/meshes/box.mesh");
// set node transformation
node.WorldTransform = MathLib.Translate(new vec3(x * 2.0f, y * 2.0f, 0.0f));
// set a name for the node
node.Name = String.Format("mesh_{0}_{1}", x + 10, y + 10);
// add the node as a child to the root dummy node
root.AddWorldChild(node);
}
}
}
