-- exception handler test module
|
|
--
|
|
--
|
|
-- To avoid this from crashing the module will startup in inactive mode.
|
|
-- to make specific errors happen you need to cause them by following
|
|
-- chat command:
|
|
--
|
|
-- exceptiontest <location> <errortype>
|
|
--
|
|
-- location has to be one of:
|
|
-- * mapgen: cause in next on_generate call
|
|
-- * entity_step: spawn a entity and make it do error in on_step
|
|
-- * globalstep: do error in next globalstep
|
|
-- * immediate: cause right in chat handler
|
|
--
|
|
-- errortypes defined are:
|
|
-- * segv: make sigsegv happen
|
|
-- * zerodivision: cause a division by zero to happen
|
|
-- * exception: throw an exception
