Adds asynchronous implementations of the Action and DistancedAction
classes, allowing plugins to make use of suspendable functions in Kotlin
instead of creating mini state machines to keep track of state.
The asynchronicity works by creating coroutine backed Channels for each
asynchronous action and having them listen on "pulse" events from the
action scheduler. The action can then suspend execution until a pulse is
received or until some expensive operation has completed (i.e.,
pathfinding).
If an asynchronous action is still busy when a pulse arrives then the
number of missed pulses will be accumulated and sent to the action at
the next possible time.
The training dummy plugin has been updated to use asycnrhonous actions
as an example.
Refactors the test helpers to use receiver functions so multiple players
can exist in the world per test case. The AddFriendsTest is an example
of where this is needed.
Additionally, Hamcrest has been replaced with AssertJ for fluent
assertions.
Adds a basic testing framework suitable for plugins that start simple
Actions for players, which can be expanded on in the future. The
banking and training dummy tests have been updated to use this framework
and serve as samples.
Adds separate build tasks for each plugin by auto-discovering plugin meta
files in the build script. Each plugin will automatically have its
main sources and tests compiled, and then it's output added to the game
modules classpath.
This enables support for incremental compilation of scripts, as well as
unit testing using Gradle's test framework.
