Unreal Engine 4

This document provides information you need before starting to develop with the SDK.

Common for all OS

This section describes common information for all operating systems.

Runtime logs

To check SDK logs when running the app, set useLog to true in the Configuration class.

Setting runtime log type

You can select specific log types to view from the SDK logs. You can set the SDK log type using the Logger.setLogFilter API. The default setting is LogType.Verbose among the 6 types below.

  • LogType.Verbose: Development stage output logs
  • LogType.Debug: Detailed logs for all stages
  • LogType.Info: SDK progress and result callbacks (recommended)
  • LogType.Warning: Unexpected situations occur, but errors that do not affect game execution
  • LogType.Error: Errors that affect game execution due to missing configuration information
  • LogType.None: Does not output any logs

The log type order is as follows, from high to low level, and only logs lower than the set log type will be output.

Verbose > Debug > Info > Waring > Error > None 

LogFilter logFilter = new LogFilter();
logFilter.coreLog = LogType::Info;
logFilter.serviceLog = LogType::Info;

Logger.setLogFilter(logFilter);
