Function AstarPath.AllocateNodes

Unity.Jobs.JobHandle AllocateNodes<T> (

T[]	result	Node array to fill
int	count	How many nodes to allocate
System.Func<T>	createNode	Delegate which creates a node. () => new T(). Note that new T(AstarPath.active) should *not* be used as that will cause the node to be initialized twice.
uint	variantsPerNode	How many variants of the node to allocate. Should be the same as GraphNode.PathNodeVariants for this node type.

)

Allocate a bunch of nodes at once.

This is faster than allocating each individual node separately and it can be done in a separate thread by using jobs.

var nodes = new PointNode[128];
var job = AstarPath.active.AllocateNodes(nodes, 128, () => new PointNode(), 1);

job.Complete();
