#summary List of engine error codes

When the engine crashes or is closed, it returns an exit code (or error code) which can be used to further analyze the problem.

= List of engine error codes =
This is the list of all possible error codes:

|| Exit code || Meaning || Description || Solution ||
|| 0 || No error || Engine exited normally || N/A ||
|| 51 || Usage error || The engine was launched with invalid command line arguments || Check your command-line arguments. Use `hwengine --help` for a list ||
|| 52 || Fatal error || Generic error for critical errors. Commonly happens when a critical file like an image was not found || Check the error message or the end of `Logs/game0.log` in your [http://hedgewars.org/wiki/User_directory user directory] for clues ||
|| 53 || Startup error || Failure while initializing stuff on startup, like graphics, shader, OpenGL stuff, etc. || Check your [Dependencies] and if you have the latest drivers installed and update them as needed ||
|| 54 || Fatal error, no IPC socket || Similar to error 52, but the IPC socket is not working for some reason || Check the end of `Logs/game0.log` in your [http://hedgewars.org/wiki/User_directory user directory] for clues ||
|| Other || Free Pascal run-time error. This is probably a bug || See [https://www.freepascal.org/docs-html/user/userap4.html Free Pascal run-time errors] || [http://www.hedgewars.org/bugs Report a bug], then someone should fix it ||

= Error codes when performing engine test cases =
When the engine is used to perform [EngineTestCases test cases], the follwing additional codes are used:

|| Exit code || Meaning || Solution ||
|| 0 || Test succeeded || N/A ||
|| 60 || Test failed || Fix the engine ||
|| 61 || Lua error in test case || Fix the Lua code of the test case ||
|| 62 || Unexpected error while testing || Debug ||
