Hi @jmesyan, could you specify better how you're trying to test it? Like, against which server? Are you running all pitaya deps? (nats, etcd)?

I've updated master branch for using the c++ plugin and also updated the unity-example, can you try it again?

best

@felipejfc I use the macbook,and the environment next:

now when I make build, follow the error:

make build

make: *** [build] Error 1

[felipejfc]

hi @jmesyan that's because we have switched from a golang implementation of the native plugin to a c++ one, the reason is that unity has some troubles dealing with go native plugins

@felipejfc , make error:

[felipejfc]

hi @jmesyan you don't really need to build the plugins by yourself to run the examples, it's already built here https://github.com/topfreegames/libpitaya-cluster/tree/master/unity-example/Assets/Plugins, also, for using libpitaya-cluster into your project you can use the official nuget package https://www.nuget.org/packages/LibPitayaServerCpp/

hi @felipejfc ，now the unity didn't report any bug, but when I click the button,the unity crashed, I am not familiar with unity, I intend to give up the test temporary, thank you for your help, do you have other library for layabox or cocos creator?

[felipejfc]

Can you better describe your use case for this lib? we don't officially support layabox or cocos creator but as it's a c++ library you could create the bindings yourself...

hi @felipejfc , I can't find any detail log when the unity is crashed, so I change the unity version to 2017.4.0f1 , use the old version code, and run the go-server. click the init libpitaya button, it is ok, but click the sendrpc button, run the error below and can't find any message in the console, could you tell me how to fixed it:

ERRO[0552] server 984539ee-c22a-4635-8e73-a55d0513cf95 doesn't have a grpc-host specified in metadata  source=pitaya

[felipejfc]

This shouldn't happen if you use the version from the master, can you try?
