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.
Integrates the plugin script compilation task with Gradle so we no
longer need to start a new instance of the JVM for each set of plugin
scripts that we want to compile.
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.
Adds gradle tasks to build all plugin scripts under data/plugins with
the KotlinPluginCompiler implementation previously used for runtime code
generation. In addition to .plugin.kts files, scripts can also declare
API code in .kt files which will also be included on the classpath and
made available to other plugins.
Creates a new sourceset for server plugins to support IDE integration
with plugin code. Additionally moves plugins to game/data/plugins and
contains some gradle related fixes (remove java plugin from root project
and fix exec task dependency).
Ports the Maven build POMs to Gradle build scripts, which are a bit
friendlier to use. Instead of using the exec:java Maven goal to run the
server now, the gradle run task should be used.
Implements a new MobExtension plugin which adds 'follow', and 'chase'
mixins that allow the mob to follow behind another mob, and chase them
while keeping at a safe distance to fire projectiles. Also adds a new
public method 'raycast' to CollisionManager, for drawing a line through
the world using bresenham's line algorithm whille checking for any impenetrable
objects.
Adds a new mob extension plugin which creates a walk_to() method on
Mobs to allow walking to another entity (accounting for the size of the
entity) with an optional facing position.
Adds a mob-extension plugin, which allows creating modules as mixins to
be monkey-patched into the Mob class. Having a standard method of doing
this prevents confusing problems with mixin name conflicts, by allowing
the plugin to raise an error that 2 mixins with the same name exist.
Adds tests for the CollisionManager which makes sure that collision
matrices are correctly built for the following object types:
* Interactables
* Walls
* Corners
Missing from these tests are tests for blocked / bridged tiles, and
large corner walls, which can be added later. Additionally, the test
cases include ASCII illustrations of the collision grid and how it is
built / checked for a particular object or movement.
This commit implements collision detection using the map files loaded
from the cache, and adds support for modifying the collision matrices at
runtime when the game world is updated.
All checks to see if a tile is reachable should now be done via.
World#traversable, instead of Region#traversable, as the World object
can handle checking tiles across multiple regions. These are done for
the WalkingQueue and Pathfinder implementations.
Adds the ability to register region listeners with the
RegionRepository, which will register the listener with any existing
regions and cache it for any newly created regions later.
Refactors the map file loading code by importing existing code from the
Vicis cache editor project. Adds classes for decoding objects and tiles
for a given map file index. Only the new MapIndex decoder code is used
when loading GameObjects at the moment , which will later be updated.
* Adds support for short-lived entities, which are never added to the
entity sets of the region they belong in.
* Adds support for checking the number of tiles a Mob occupies.
* Adds a ProjectileBuilder class to simplify creating projectiles.
Makes sure that the steps in a path sent for a "Player Walk" message are
on the same level as the players current position while being processed
in the walking queue.
Add rules for enforcing tabs in Java, and spaces in Ruby.
Add a rule to make sure trailing whitespace is trimmed
and that no new final newline is inserted.
Add various tests around ItemOnObject messages to verify that a valid
object needs to be given as well as a valid item in order for the
message to be passed down the MessageHandlerChain.
Add a test which verifies an ObjectActionMessage is terminated if its
not within the specified distance of the player.
Additionally add a test which verifies that an ObjectActionMessage is
terminated if there is no object with the given id nearby.
