The reason why *checkwall exist

During that time, I was cleaning up my battleground script template,
I didn't notice the *delwall script command was used twice <-- thanks to Atemo !
thus I made a pull request to throw a debug message when *delwall use twice

it was done that way because I thought *delwall script command is only meant for event script
when event commence = *setwall, and when start = *delwall ... simple as that

then I immediately receive complaints many server throw errors on them because of my pull request
when I ask how they get the error, answer was shocking for me
they actually use the *setwall/*delwall for Utility script !!

I can't remember the conversation or the script, but its something like this
- script sdfsdf -1,{ OnInit: switch ( gettime(GETTIME_WEEKDAY) ) { case SUNDAY: goto OnSun0000; case MONDAY: goto OnMon0000; case TUESDAY: goto OnTue0000; case WEDNESDAY: goto OnWed0000; case THURSDAY: goto OnThu0000; case FRIDAY: goto OnFri0000; case SATURDAY: goto OnSat0000; } OnMon0000: OnWed0000: OnFri0000: delwall "Weekday_wall2"; delwall "Weekend_wall"; setwall <map>,<x>,<y>,<size>,<dir>,0,"Weekday1_wall"; end; OnTue0000: OnThu0000: delwall "Weekday_wall1"; delwall "Weekend_wall"; setwall <map>,<x>,<y>,<size>,<dir>,0,"Weekday1_wall2"; end; OnSat0000: OnSun0000: delwall "Weekday_wall1"; delwall "Weekday_wall2"; setwall <map>,<x>,<y>,<size>,<dir>,0,"Weekend_wall"; end; }

Honestly I have no answer for them at the time ...

and thus the *checkwall script command was added later to fix this issue


Moral of the story : never underestimate the creativity of the community =/
well ... enablenpc/disablenpc ... this script command also doesn't throw error when use multiple times
imagine if we actually throw error for the *disablenpc .... hahaha~
