Summary0001596: SECTOR-LIGHT change with on@environchange crashes server
DescriptionHello everybody,

i'm running a serverclock ingame which controls the lightlevel of the whole map.
This clock "tells" the sectors which lightlevel is used by now. The clock sends via serv.allclients the lightvalue to the char and to a tag.

If the char changes an environment, the script checks if the sectorlightvalue is equal to the actual lightvalue stored in tag.helligkeit.

This causes the server to crash! We've tried this with "d" (eval) and without.
It crashes not everytime! But very often.
The server shuts down without any comment in the log.

=========================

SECTOR.LIGHT=<dSRC.TAG.HELLIGKEIT>

=========================
Hope you can help me!

Changing the light level will cause the @EnvironChange trigger to be fired. Since your script is changing the light level inside the @EnvironChange trigger this is causing the trigger to be fired again (and again and again, etc) indefinately until the server eventually crashes.

Thank you for your instantly answer MrSugarCube.

I'm sorry for bugging you again with that topic, but I forgot to post, that we already prevented the neverending (story) function with:

if (<eval <SRC.SECTOR.LIGHT>> != <eval <SRC.TAG.HELLIGKEIT>>)

Because of this, the environchange should be fired only once per change.

We've been using this script for at lest 4 years on an 55i shard and it worked without any error. Since migrating to 56b it (sorry) sucks ;). We've checked the scriptcode multiple times... Even the allknowing *G* uodev.de couldn't find the answer to our problem...

Thank you for reading.

I have no problems when using the following trigger. I suspect that you may have an invalid light level in your tag, since trying to set it to an out-of-range value will still cause @EnvironChange to be triggered again (and since the light is not set to the value you expect, you would then continue to set the light level).

Of course since you're only revealing your script one line at a time I can only guess as to what could be happening in it, perhaps you're also setting the weather in there or doing something else to set off a different loop. Maybe there's even a SERV.SHUTDOWN in there. :P

ON=@EnvironChange
    IF (<ISEMPTY <TAG.LIGHTLEVEL>>)
        RETURN 2
    ENDIF
    SERV.LOG @@EnvironChange(<TAG0.LIGHTLEVEL>, <SECTOR.LIGHT>)
    IF (<TAG0.LIGHTLEVEL> >= 0) && (<TAG0.LIGHTLEVEL> <= 30)
        IF (<SECTOR.LIGHT> != <TAG0.LIGHTLEVEL>)
            SECTOR.LIGHT = <TAG0.LIGHTLEVEL>
        ENDIF
    ENDIF
    RETURN 2

Thank you for your help!
I modified my scripts now to work without the entry in the environchange section.

This problem is no bug and can be closed!
