This is the server log : 22T07:18:29.441Z","caller":"server/pipeline.go:65","msg":"Received *rtapi.Envelope_Rpc message","uid":"1402bb25-a0fb-4172-be23-ed560786bbeb","sid":"04125abe-62f7-11ec-825f-688e25b5a5ca","cid":"20","message":{"Rpc":{"id":"customFunction","payload":"test"}}}
WebSocketException: RPC function not found
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw () [0x0000c] in <695d1cc93cca45069c528c15c9fdd749>:0
And why ? The custom function is the example provided in the doc, it’s registered in the initModule in the main.ts script like I provided, the hello world message appears, why would the custom function not being registered as it’s in the main.ts file ? I tried to check in the local.yml file to see if by changing the runtime path it would solve the problem but no. The function also appears correctly in the index.js script.
I feel like when I make a change to a ts script, modifications are not taken into account.
If for example I comment out a function and its initializer, it stills appears as loaded in the server log (I’m trying to change the function and it was not working) despite having compiled several times.
After some digging, I tried to copy your example of the pokeapi. At first it was not working despite doing everything right (intiliazer, dockerfile, tsconfig)
It only worked when I deleted the images and volume in Docker and recreated a new server. Is this how it is supposed to work ?
When I submit a string payload to a rpc, the server returns me that error “JavaScript runtime function raised an uncaught exception”,“mode”:“rpc”,“id”:“custom_rpc_func_id”,“error”:“SyntaxError: invalid character ‘S’ looking for beginning of value at parse (native)”}
if I try to put the same payload as the pokeapi example, “{“PokemonName”: “dragonite”}” it also returns the same error.
Terminal shows an error : unknown shorthand flag: ‘f’ in -f.
For rpcs, I understand that there json involved but I can’t rellay wrap my head around how exactly am I suppose to send to the server a float, an int or a bool and get back from it a int, a float or a bool. I know it may sound stupid but I think I’m at a stage where I can ask stupid questions.
//We this to encode and decode json data with the server
public class TestObjectClass
{
public int playerBetInt = 2;
public bool playerBetEven = true;
}
public async void TestCustomFunction()
{
//Make a new object that we will send to the server in json
TestObjectClass testObject = new TestObjectClass();
testObject.playerBetInt = 7;
testObject.playerBetEven = false;
string jsonFromClient = JsonUtility.ToJson(testObject);
Debug.Log(jsonFromClient);
var payload = jsonFromClient; // Server correctly receive the informations 7 and false;
var rpcid = "custom_rpc_func_id";
var responseServer = await client.RpcAsync(session, rpcid,payload);
var responseServerPayload = responseServer.Payload;
//Decode the server return object
TestObjectClass serverObjectResponseDecoded = JsonUtility.FromJson<TestObjectClass>(responseServerPayload);
Debug.LogFormat("Server answer is :", serverObjectResponseDecoded);
Debug.Log(serverObjectResponseDecoded);
Debug.Log(serverObjectResponseDecoded.playerBetInt);
Debug.Log(serverObjectResponseDecoded.playerBetEven);
//Information coming back is wrong as it 2 and true, the default values of the class.
}
In the custom rpc ts:
let customFuncRpc: nkruntime.RpcFunction =
function (ctx: nkruntime.Context, logger: nkruntime.Logger, nk: nkruntime.Nakama, payload: string) {
logger.info('payload: %q', payload);
// "payload" is bytes sent by the client we'll JSON decode it. Works
let json = JSON.parse(payload);
let playerBet=json['playerBetInt'];
let playerBetEven=json['playerBetEven'];
let betAdditive=5;
/*I tried several ways to get the data from the json to modify it and send it back with no success
*The last one is just to make a serverResponse object with defined values and sent it back as a return value to the client.
*Not working*/
/*let newPlayerBet=playerBet+betAdditive;
let newPlayerBetEven=false;*/
let serverResponse=
{
newPlayerBet:85,
newPlayerBetEven:false,
}
return JSON.stringify(serverResponse);
}
First, the playerBet in the TS needed to have the exact same name as its counterpart in Unity (logic).
But also, this :
docker-compose -f filename.yml up --build nakama
does not work, it creates new images that interfere with the code, the only way to get it working properly is to delete the container, images and volumes each time I have a code modification to make, otherwise it won’t properly work.
How do you write a console debug message or show a debug value for a variable ? (for functions not in nakama namespace)
When I try console.log(“Message error”) or console.log(booleanvariable) the server gives me that error :
ReferenceError: console is not defined in “name of the function where I called it”
