Tree definition

The tree definition denotes a part of the tree (so-called subtree) that defines an independent description and can

• have the input parameters and accept arguments including other trees definitions
• invoke other tree definitions and get invoked by others (except root)

There are the following types of the definitions:

• Flow: the core part of the behavior tree framework. The nodes define a logic of processing the tree itself, navigating for the next step.
• Lambda: The anonymous definition of subtree with instant invocation at this place.
• Decorator: the atomic built-in tree definition that has one child and can enrich or transform the child result according to its type.
• Actions: the leaves of the tree bearing the business logic.
