Sadly i will only be able to give the code this weekend; and can you tell me which C# file and if you need the playercontroller.cs the fact i changed the movement is not something like a typo because i adapted it for mobile.
Thanks for the support!
Hi i have the same problem like @KYNUX @thecil
When i press the button "Purchase "like in the videos this happends
The code of the purchase script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using EnjinSDK;
public class StoreController : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
async public void PurchaseUniCoin()
{
string coinTokenId = "30000000000010b6";
string enjinId = "0";
string adminAddress = LoginManager.loginManagerInstance.adminAddress;
EnjinItemParameter [] sendItems= new EnjinItemParameter[]{ EnjinItemParameter.ConstructFungible(enjinId, 1)};
EnjinItemParameter [] receiveItems= new EnjinItemParameter[]{EnjinItemParameter.ConstructFungible(coinTokenId, 10)};
IRequestHandler tradeHandler = LoginManager.loginManagerInstance.userIdentity.
CreateTradeItemRequestHandler(sendItems,receiveItems,adminAddress);
await tradeHandler.RegisterCallback(RequestEventType.CreateTradePending, requestEvent =>
{
Debug.Log("Create Trade Request |Pending Done|");
});
await tradeHandler.RegisterCallback(RequestEventType.CreateTradeBroadcast, requestEvent =>
{
Debug.Log("Create Trade Request |Broadcast Done|");
});
await tradeHandler.RegisterCallback(RequestEventType.CreateTradeExecuted, async requestEvent =>
{
string tradeID = requestEvent.Data.param1;
Debug.Log("Create Trade Request |Execution Done|");
//accept the trade
IRequestHandler tradeAcceptHandler = LoginManager.loginManagerInstance.adminIdentity.CompleteTradeItemRequestHandler(tradeID);
await tradeAcceptHandler.RegisterCallback(RequestEventType.CompleteTradePending, completeEvent =>
{
Debug.Log("Complete Trade Request |Pending Done|");
});
await tradeAcceptHandler.RegisterCallback(RequestEventType.CompleteTradeBroadcast, completeEvent =>
{
Debug.Log("Complete Trade Request |Broadcast Done|");
});
await tradeAcceptHandler.RegisterCallback(RequestEventType.CompleteTradeExecuted, completeEvent =>
{
Debug.Log("Complete Trade Request |Execution Done| ~ Trade is done");
});
await tradeAcceptHandler.Execute();
});
await tradeHandler.Execute();
}
}

http request 400 means a bad request, might be that the enjin server is not responding, i will check my self and get back to you this weekend, will try to run my code again and should work.
I dont see any error in the code that you provide, so it must be something else

Ok thx, i hope you can find the problem so i can continue with the course 
Hey @thecil,
did you already take a look at the problem?
I don’t wanna stress you but i wanna continue with my project and this bug does not let me 
Hey, sorry for the delay man, I might need to check your project to get a better picture, the issue you refer is could be a syntax issue on your http request to enjin servers, which could be incorrect somewhere.
Would be great if you can upload your project to a github repo so i can replicate the issue myself.
Carlos Z
Yes, sorry for the delay man, I have closely follow filip videos and verify your code, the only issue that i found, which is also named on your terminal is on the last argument function in your tradeHandler callbacks.
Yours:
await tradeHandler.RegisterCallback(RequestEventType.CreateTradePending, requestEvent =>
{
Debug.Log("Create Trade Request |Pending Done|");
});
Filip:
await tradeHandler.RegisterCallback(RequestEventType.CreateTradePending,
(requestEvent) => {
Debug.Log("Create Trade Request |Pending Done|");
});
