cark.keechma.behavior-tree.controller — cark/cark.keechma.behavior-tree 0.1.6

Use the namespace provided here to create your own keechma behavior tree controllers

<cmd-send-event cljs

(<cmd-send-event ctx event-name)

(<cmd-send-event ctx event-name arg)

This function send a command to the controller. This will result in sending a behavior tree event to the controller's behavior tree. The function is intended to be used from a component, passing its context as the first parameter. The second parameter is the event name, a keyword. The third optional parameter is the event argument.

<cmd-tick cljs

(<cmd-tick ctx)

This function sends a command to the controller. This will result in the controller's behavior tree to be ticked. That function is intended to be used from a component, passing its context as parameter.

app-db-path cljs

(app-db-path controller)

Returns the path to the behavior tree database in the app-db, as seen by the controller.

blackboard-reaction cljs

(blackboard-reaction controller-name)

Returns a function that takes an app-db-datom and returns a reagent reaction on the controller's blackboard.

Controller cljs

default-api cljs

execute-send-event cljs

(execute-send-event controller event-name)

(execute-send-event controller event-name event-arg)

This function sends a behavior tree event to the controller's behavior tree. It may be called during the execution of the :on-start and :on-stop functions as well as during the execution of the behavior tree event handlers.

execute-tick cljs

(execute-tick controller)

This function ticks the behavior tree. It may be called during the execution of the :on-start and :on-stop function as well as during the execution of the behavior tree event handlers.

get-blackboard cljs

(get-blackboard app-db controller-name)

Returns the blackboard for this controller

handle-bt-event cljs

(handle-bt-event this app-db-atom event-name arg)

This internal function handles an event coming out of the behavior tree.

handle-bt-events cljs

(handle-bt-events this app-db-atom)

This internal function loops over the events coming out of the behavior tree, processing these according to the controller's configuration.

make cljs

(make params-func controller-api)

Returns a new behavior tree controller, customized with a behavior tree and associated parameters. Parameters:

• params-fun : The params function is a regular keechma controller params function. It receives the controller as first parameter, and a route-params map as second parameter. It should return true if the controller is to be run in that context, false otherwise.
• controller-api : This map may have several keys :
  • :on-start : this is the optional regular :on-start keeshma controller function. It receives the controller as first parameter, the params map as second argument, and the app-db as third argument. This function must return a possibly updated app-db.
  • :on-stop : this is the optional regular :on-stop keeshma controller function. It receives the controller as first parameter, the params map as second argument, and the app-db as third argument. This function must return a possibly updated app-db.
  • :tree : this is the actual behavior tree context, as returned by bt/hiccup->context on an hiccup notation behavior tree.
  • :tree-init-func : this function receives the current behavior tree context and returns an initialized tree. This function is called when the controller is started
  • :tree-events : this map has keyword event names as keys and event handler functions as values. An event handler receives the controller instance as its first parameter, the app-db-atom as its second parameter and the event arg as third parameter.

name->app-db-path cljs

(name->app-db-path name)

Returns the path to the behavior tree database in the app-db

set-blackboard cljs

(set-blackboard app-db-atom controller-name value)

Sets the balckboard value for this controller.

update-blackboard cljs

(update-blackboard app-db-atom controller-name func & args)

Updates the blackboard of this controller with the func and args.
