NodeDummy Class
Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.
| 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.
Source code (UnigineScript)
#include <core/unigine.h>
int init() {
// create a dummy node
NodeDummy dummy = new NodeDummy();
// set a name
dummy.setName("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.
Source code (UnigineScript)
#include <core/unigine.h>
int init() {
// create a dummy node
NodeDummy root = new NodeDummy();
// set a name for the node
root.setName("root");
// create child nodes
for (int y = -10; y <= 10; y++)
{
for (int x = -10; x <=10; x++)
{
// create a mesh
Mesh mesh = new Mesh();
mesh.addBoxSurface("box_0", vec3(1.0f));
// create a node (an instance of the ObjectMeshStatic class)
ObjectMeshStatic node = new ObjectMeshStatic(mesh);
// set node transformation
node.setWorldTransform(translate(Vec3(x * 2, y * 2, 0.0f)));
// set a name for the node
node.setName(format("mesh_%d_%d", x + 10, y + 10));
// add the node as a child to the root dummy node
root.addWorldChild(node);
}
}
