|
| Summary | 0003949: The game ignores a negative value in "+compatflags -2147483648" command line argument |
| Description | Passing +compatflags -2147483648 as a command line argument should enable the compat_maskedmidtex compat flag. It doesn't:
- compatflags are 0
- compat_maskedmidtex is false
If "compatflags -2147483648" is set from the console, the game accepts it just fine, so it appears that only parsing the command line is broken. |
| Steps To Reproduce | 1. Run "zandronum.exe -iwad doom2.wad +map map01 +compatflags -2147483648". |
| Additional Information | The dmflags, compatflags and zaflags are all signed 32-bit integers. The compat_maskedmidtex is the only flag that uses the most significant bit of a 32-bit integer. |
| Tags | No tags attached. |

to recap our findings on discord:
also an issue in zan 3.0 where the flag was backported
also an issue in gzdoom 1.8.6
fixed in gzdoom 4.7.0 |

Actually kind of surprised it got noticed in GZDoom (unless it was an incidental fix from a rewrite or something).
I'm guessing the issue is that it's assuming the dash is starting a new command line parameter instead of being part of the console command. It can be worked around in the mean time by putting a space before the minus sign, or even sending "+compatflags -2147483648" as one argument. Obviously not something we'd want to use permanently though. |

So, I tried that, and unfortunately it only works when launching an offline game. When I add "-host" to the command line, the server starts with compatflags 0. |

OK, another work around which works with -host in my testing: +eval 0x80000000 compatflags |

Unfortunately no: zandronum_eval_flags_doesnt_really_work_either.jpg
It sets the value, but only up to the max signed value. |

upon further inspection, it seems the compatflags and compatflags2 fields dont work at all
to reproduce:
set all the flags fields to a value of 2 and start the server, then check them on the server, compatflags and compatflags2 will return 0 instead of 2
[...]
regarding compatflags/compatflags2 i think this is a zan 3.1 regression unless im doing something terribly wrong, requires even further inspection

Since the problem is different and there has been some discussion here already about the negative values, I'm closing this ticket and opened a new one at 0003956.

Huh, that's quite interesting. It definitely does work for me on Linux (attached screenshot). Although I wouldn't be surprised if it was a libc difference in that case or something. There's probably another expression you could pass to eval to get it to work, but yeah something is weird with compatflag handling regardless. |
