Unigine.World Class
This class provides functionality for the world script. It contains methods required for loading the world with all its nodes, managing a spatial tree and handling nodes collisions and intersections.
Loading of nodes on demand is managed via the AsyncQueue Class.
Notice
C++ methods running editor script functions are described in the Engine class reference.

int isAutoReloadNodeReferences()
Returns a value indicating if automatic reloading of NodeReferences is enabled. If enabled all NodeReference nodes will reload their *.node files, when the saveNode() method is called.Notice
This option can be used if you modify and save reference nodes at runtime. Otherwise you'll have to manually update pointers for all NodeReferences referring to the changed node.
Return value
1 if automatic reloading of NodeReferences is enabled; otherwise, 0.void setAutoReloadNodeReferences(int val)
Enables automatic reloading of NodeReferences. If enabled all NodeReference nodes will reload their *.node files, when the saveNode() method is called.Notice
This option can be used if you modify and save reference nodes at runtime. Otherwise you'll have to manually update pointers for all NodeReferences referring to the changed node.
Arguments
- int val - 1 to enable automatic reloading of NodeReferences; 0 - to disable it. The default value is 0.
void setBudget(float budget)
Sets the world generation budget value for Grass and Clutter objects. New objects are not created when time is out of the budget.Arguments
- float budget - The budget value in seconds. The default value is 1/60.

Returns the value of the world generation budget for Grass and Clutter objects. New objects are not created when time is out of the budget.Return value

Updates the node BSP (binary space partitioning) tree.
The engine calls this method automatically each frame after the world script update() code is executed. As a new node becomes a part of the BSP tree only after this method is called, all engine subsystems (renderer, physics, sound, pathfinding, collisions, intersections, etc.) can process this node only in the next frame. If you need the subsystem to process the node in the very first frame, you can call the updateSpatial() method manually. The engine will call this method automatically after the update() code is executed anyways.
