Unigine::Node Class
Header: | #include <UnigineNode.h> |
In terms of Unigine, all of the objects added into the scene are called nodes. Nodes can be of different types, determining their visual representation and behavior.
The node is created and stored in the world. All changes are saved into the .world file.
The node can be also saved into an external .node file and then imported into the world when necessary. Also it is possible to create a reference to the exported node.
You can associate any string data (written directly into a *.node or a *.world file) or an arbitrary user variable with a node.

- How to work with the node's matrix transformations
Creating a Node#
The Node class doesn't provide creating of a node. You can create an instance of any class inherited from the Node class and then obtain the node via automatic upcasting
For example:
- Create a box mesh by using the Mesh class.
- Use the box mesh to create an instance of the ObjectMeshStatic class. This class is inherited from the Node class.
- Get the node via upcasting.
// AppWorldLogic.cpp
#include "AppWorldLogic.h"
#include <UnigineNode.h>
#include <UnigineObjects.h>
using namespace Unigine;
using namespace Math;
int AppWorldLogic::init() {
// create a mesh
MeshPtr mesh = Mesh::create();
mesh->addBoxSurface("box_0",vec3(1.0f));
// declare a smart pointer for any type of the node inherited from the Node class (e.g. ObjectMeshStatic)
// and call a constructor of the corresponding class
ObjectMeshStaticPtr object_mesh = ObjectMeshStatic::create(mesh);
// declare a smart pointer for the node
// and obtain the node pointer from the created ObjectMeshStatic
NodePtr node = object_mesh;
return 1;
}
Now you can operate the ObjectMeshStatic instance as a node.
Editing a Node and Saving Changes#
The Node class contains common settings of the node. Also each node has special settings, which vary depending on the type of the node.
Editing the node also includes editing materials and properties assigned to the node.
For the edited node to be saved in the .world file, you should enable the corresponding option via the setSaveToWorldEnabled() method.
For example:
- Create a box mesh by using the Mesh class.
- Save the mesh on the disk. It is required as the node we are going to save to the .world file need to reference to a mesh stored on the disk.
- Use the saved .mesh file to create an instance of the ObjectMeshStatic class. This class is inherited from the Node class.
- Get the node from the ObjectMeshStatic instance via upcasting.
- Enable saving to .world file for the node (and all its children).
- Edit the node and save the world by calling the world_saveconsole command.
#include "AppWorldLogic.h"
#include <UnigineNode.h>
#include <UnigineObjects.h>
#include <UnigineWorld.h>
#include <UnigineConsole.h>
using namespace Unigine;
using namespace Math;
int AppWorldLogic::init() {
// create a mesh
MeshPtr mesh = Mesh::create();
mesh->addBoxSurface("box_0",vec3(1.0f));
// save a mesh into a file on the disk
mesh->save("unigine_project/meshes/my_mesh.mesh");
// declare a smart pointer for any type of the node inherited from the Node class (e.g. ObjectMeshStatic)
// and call a constructor of the corresponding class create an instance of any class inherited from the Node class (e.g. ObjectMeshStatic)
ObjectMeshStaticPtr object_mesh = ObjectMeshStatic::create("unigine_project/meshes/my_mesh.mesh");
// declare a smart pointer for the node,
// obtain the node pointer from the created ObjectMeshStatic,
NodePtr node = object_mesh;
// enable saving the node(and all its children) to a .world file
node->setSaveToWorldEnabledRecursive(true);
// change the node name
node->setName("my_node");
// change node transformation
node->setWorldTransform(translate(Vec3(0.0f, 0.0f, 2.0f)));
// save node changes in the .world file
Console::run("world_save");
return 1;
}
Exporting and Importing a Node#
To export a node stored in the world into the external .node file, you should pass it to the saveNode() method of the World class.
To import the existing node stored in the .node file to the world, you should call the loadNode() method of the World class.
For example:
- Create a box mesh by using the Mesh class.
- Save the mesh on the disk. It is required as the node we are going to export need to reference to a mesh stored on the disk.
- Use the saved .mesh file to create an instance of the ObjectMeshStatic class. This class is inherited from the Node class.
- Get the node from the ObjectMeshStatic instance via upcasting.
- Export the node to an external .node file.
- Import the prevoiusly exported node to check the result.

#include <UnigineWorld.h>
#include <UnigineEditor.h>
#include <UnigineConsole.h>
using namespace Unigine;
using namespace Math;
int AppWorldLogic::init() {
// create a mesh
MeshPtr mesh = Mesh::create();
mesh->addBoxSurface("box_0", vec3(1.0f));
// save a mesh into a file on the disk
mesh->save("unigine_project/meshes/my_mesh.mesh");
// create an instance of any class inherited from the Node class (e.g. ObjectMeshStatic)
ObjectMeshStaticPtr object_mesh = ObjectMeshStatic::create("unigine_project/meshes/my_mesh.mesh");
// declare a smart pointer for the node
// and obtain the node pointer from the created NodeDummy
NodePtr node = object_mesh;
// export the node into a .node file
World::saveNode("unigine_project/nodes/my_node.node", node);
// import the exported node to check the result
NodePtr imported_node = World::loadNode("unigine_project/nodes/my_node.node");
// set position of the node
imported_node->setPosition(Vec3(4.0f, 0.0f, 1.0f));
return 1;
}
Deleting a Node#
By default each new node's lifetime matches the lifetime of the World (i.e. such node shall be deleted when the world is closed). But you can also choose node's lifetime to be managed:
- by the Engine - is this case the node shall be deleted automatically on Engine shutdown.
- manually - is this case the node should be deleted manually by the user.
To delete a node you can use the following two methods:
- deleteLater() - performs delayed deletion, in this case the object will be deleted during the next swap stage of the main loop (rendering of the object ceases immediately, but it still exists in memory for a while, so you can get it from its parent, for example). This method simplifies object deletion from a secondary thread, so you can call it and forget about the details, letting the Engine take control over the process of deletion, which can be used for future optimizations.
- deleteForce() - performs immediate deletion, which might be necessary in some cases. Calling this method for main-loop-dependent objects (e.g., nodes) is safe only when performed from the Main thread.

- MathLib::AXIS axis - Axis along which the direction vector should be pointed. The default is the negative Z axis.
Math::vec3 getWorldDirection ( MathLib::AXIS axis = AXIS_NZ ) #
Returns the normalized direction vector pointing along the given node axis in world coordinates. By default, the direction vector pointing along the negative Z axis of the node is returned. The direction vector always has a unit length.node->getWorldDirection(node->isPlayer() ? Math::AXIS_NZ : Math::AXIS_Y); // forward direction vector
node->getWorldDirection(node->isPlayer() ? Math::AXIS_Z : Math::AXIS_NY); // backward direction vector
node->getWorldDirection(node->isPlayer() ? Math::AXIS_Y : Math::AXIS_Z); // upward direction vector
node->getWorldDirection(node->isPlayer() ? Math::AXIS_NY : Math::AXIS_NZ); // down direction vector
node->getWorldDirection(Math::AXIS_X); // right direction vector
node->getWorldDirection(Math::AXIS_NX); // left direction vector
Arguments
- MathLib::AXIS axis - Axis along which the direction vector points. The default is the negative Z axis.

Ptr<WorldBoundBox> getSpatialBoundBox ( ) #
Returns a bounding box with world coordinates that participates in physics calculations, but doesn't take children into account. This bounding box is used by the spatial tree.Return value
The bounding box with world coordinates.Ptr<WorldBoundSphere> getSpatialBoundSphere ( ) #
Returns a bounding sphere with world coordinates that participates in physics calculations, but doesn't take children into account. This bounding sphere is used by the spatial tree.Return value
The bounding sphere with world coordinates.BoundBox getHierarchyBoundBox ( ) #
Returns a bounding box with local coordinates that takes children into account, but doesn't participate in physics calculations. Exclusion of objects from the spatial tree significantly reduces the size of the tree and improves performance due to saving time on bounding box recalculation when transforming nodes.Return value
