Summary

0001115: Change ACS runaway script threshold from 500,000 to a variable or something higher

Description

The limit of 500,000 is slowly becoming archaic from some of our mods that can push the engine quite far. ZDaemon has raised it to 2 million p-code instructions before runaway happens, and while I'm not trying to create [yet another] ZD thread, this showed me that it can be changed. It would be interesting to either up the limit for the mod developers in this community (since we're a mod driven port).

If this idea is feasible, maybe there should be a limit for the server (and clients have their own limit), like:
int sv_acsrunawaythreshold

Of course the only problem is someone could set it to 2 billion and go nuts, though they'd have to go out of their way to do such a thing; which means the server could possibly puke a log message if the threshold was changed?

Additional Information

Usually I get the message when running things like a square root formula on a lot of actors since there isn't a native square root function and does lots of stuff. When you have 4000 actors or such, there's enough calls to flood it to runaway.

(0005076) Blzut3 (administrator) 2012-10-10 21:16	This should be suggested over at ZDoom first. That said, I have a hard time believing that you guys are legitimately hitting the limit all that often. :P

(0005080) Watermelon (developer) 2012-10-11 02:14 edited on: 2012-10-11 04:38	The code in Zandronum be changed in: p_acs.cpp [line 3723] if (++runaway > 500000) to if (++runaway > 2000000) Apparently zdoom has changed it. Figured this would be a simple thing to update and test. 'http://zdoom.org/Changelog/3697/files [^]'
