DetAct-Lib

Currently, this is a prototype! There will be changes in the future. (Finishing v1.0 is planed in 2022.)

Description

DetAct-Lib is a framework which offers the possibility to define behaviour of an instance with a tree-based behaviour-model. Such a definition is described in a syntactic modelling language (BTML). Currently, a behaviour-model can be used to create a behaviour-tree.
This framework contains an interpreter to process behaviour-models and an additional set of basic classes (node-types) to create behaviour-trees. The interpreter can be extended with own node-types to create a behaviour-tree without compiling a new parser.

Example

There is an example-application for this framework. You can find it here:

(On wiki-pages there will be more examples in the future.)

Roadmap

There are many things to do until v0.5:

• add issues
• rename BTML (Behaviour-Tree Modelling Language) to TBML (Tree-based Behaviour Modelling Language)
• implement a new interpreter
  • add/overwrite node-types with C#-attributes
  • handle model-configurations
• refractor node-types to build event driven behaviour-trees
• refractor black-boards (black-board key-list -> set values at start and not in model)
• improve BTML
  • add interrupt-handling
  • add definition of memory-nodes
  • add more types for functions
  • fix bugs (i.e. node-type-parameters)
  • maybe remove the function-list (use C#-attributes instead)
• add a documentation
• create a nuget-package
