Force termination

Solar2D General Questions/Discussion
#1

I have an instance where I want to force the program (a game) to terminate and cannot find a routine which will do this. I have tried assert() and error() and neither terminates the application.

Rational: typically this would be a strange request but I am using it as a fail-safe. When my program ends I save the state in a file, which is a complicated data structure. On restart I restore it, using pcall(…) as protection. In the off chance it fails, I delete the saved state file and terminate. Thus when it restarts next time it will return to a clean initial state.

Without such protection I worry about the user never being able to run the program again without strange behavior. [import]uid: 1813 topic_id: 627 reply_id: 300627[/import]

have you tried

os.exit ([code])
Calls the C function exit, with an optional code, to terminate the host program. The default value for code is the success code.

Works like a charm (at least in the simulator). Did not even think to look in the “os” routines.

Thanks for the prompt reply.

Oh small thing, it also seems to terminate the simulator… [import]uid: 1813 topic_id: 627 reply_id: 1240[/import]
