Changelist

Read the latest changes here or the deployed changes on the website.

Description

The Spellsource-Server project is a 2-player card battler that supports hosted, networked gameplay. It features rudimentary matchmaking, collection management and support for game mechanics that persist between matches.

See the complete code reference here.

Getting Around

Cards are located at cards/src/main/resources/cards/custom.

To implement new effects (called Spells inside Spellsource) add a new Spell subclass to game/src/main/java/net/demilich/metastone/game/spells.

You can learn more about the Spellsource AI as implemented in the GameStateValueBehaviour class.

The server application starts in Clustered. ./gradlew netRun uses LocalClustered.

The client is private, please contact for access on the Discord.

Troubleshooting

I cannot clone the repository.

The GitHub Desktop app is not supported. Please use the git command line commands to clone the repository:

git clone https://github.com/hiddenswitch/Spellsource.git

I am having issues with Git Submodules, like failures to download

Public users do not have access to the private repositories that fail to download. You can safely ignore those errors. If you'd like to contribute to the private repositories, like the game client, please use the Discord invite link above and discuss with the team there.

I am seeing issues with too many files open.

On macOS, issue the following commands to increase your per-process limits:

sudo sysctl -w kern.maxfiles=5242880
sudo sysctl -w kern.maxfilesperproc=524288
ulimit -n 200000
sudo launchctl limit maxfiles 524288 5242880

testTraces is failing.

You had failures in testRandomMassPlay, the fuzzer for Spellsource. These are real issues.

I uploaded to Steam, but I do not see the build.

Visit the Steam partner's page and promote the build.

I uploaded to TestFlight but the build isn't public yet.

Make sure the Public group is added here.

The Discord bot will not compile due to an error that reads, in part, "Classes that should be initialized at run time got initialized during image building"

Add the class or the package containing it to end of the list of classes in the Args = --initialize-at-build-time=... line to native-image.properties.

You may have to regenerate reflection config using sdkman's Graal distributable. The following commands will fix this issue:

sdk use java 20.1.0.r11-grl
./gradlew --no-daemon clean
./gradlew --no-daemon discordbot:genReflectionProps

./gradlew distSwarm fails with the message of the form:

Make sure to add the sub project directory and any others that need to be visible to Docker to .dockerignore in the form of !directory/*.

discordbot Swarm build (./gradlew distSwarm) fails with com.oracle.svm.driver.NativeImage$NativeImageError: Image build request failed with exit status 137

On macOS and Windows, allocate more memory to your Docker host.

./gradlew net:run hangs with error Caused by: org.testcontainers.containers.ContainerLaunchException: Timed out waiting for log output matching '.*waiting for connections on port.*'

Make sure to use your local docker context using docker context use default.

I receive an error starting the server with gradle net:run of the form:

main ERROR o.t.d.DockerClientProviderStrategy Could not find a valid Docker environment. Please check configuration. Attempted configurations were:
Exception in thread "main" 20200811T112136 main ERROR o.t.d.DockerClientProviderStrategy     UnixSocketClientProviderStrategy: failed with exception InvalidConfigurationException (ping failed). Root cause NoSuchFileException (/var/run/docker.sock)
org.testcontainers.containers.ContainerLaunchException: Container startup failed
main ERROR o.t.d.DockerClientProviderStrategy As no valid configuration was found, execution cannot continue

Restart Docker. Make sure Docker is running.

The MongoDB container doesn't start with gradle net:run with the following error: Timed out waiting for log output matching '.*waiting for connections on port.*'

Try deleting your local database which is automatically bind-mounted to the container at .mongo:

rm -rf .mongo/

I cannot connect to the Hidden Switch cluster to deploy the servers.

You need special authorization for this. It is accessed via an audited API key.

I receive an error related to (sharp:42678): GLib-CRITICAL **: 17:17:14.186: g_hash_table_lookup: assertion 'hash_table != NULL' failed

Delete the NPM modules folder: rm -rf www/npm_modules, then rerun ./gradlew distWWW.

Autocomplete, code insight, intellisense or other code completion features are missing when I am trying to write code accessing the generating protobufs definitions, like Spellsource.java or Hiddenswitch.java

In IntelliJ, visit the Help > Edit Custom Properties... menu, then add the following lines:

# custom IntelliJ IDEA properties
idea.max.intellisense.filesize=99999
