[http://sourceforge.net/p/ufoai/bugs/2368 Item 2368] imported from sourceforge.net tracker on 2013-01-28 19:30:37

tested in r28678
the issue is 100% re-producable.
There are 2 issues being presented here.
1. I can control a door from a few tiles away
2. when I control the door from too far, the system can segfault.

1. start the skirmish map estate
2. move unit 8 into the position as indicated in image 1. (note the unit may abandon movement at the door, this is a separate defect already raised)
3. close the door (backspace)
4. move to the position as indicated by image 2
5. open the door (backspace) - this triggers the segfault.

segfault when opening door
====== tlh2000 (2010-02-23 06:27:29) ======

sv_send_edicts is a useful cvar to debug errors with doors. set it to 1 and restart the map.
====== tlh2000 (2010-02-23 06:54:34) ======

the error must be in G_ClientMove - the clientAction is not reset correctly
====== markhawrylak (2010-02-23 06:57:35) ======

when I set the cvar, then what? I imagine there is a log of output somewhere for this. help.
====== tlh2000 (2010-02-23 07:01:00) ======

no, it renders the bouding boxes of the doors and the actors. you can "see" when an actor enters a trigger area. make sure you use the latest revision for this.
====== tlh2000 (2010-02-23 07:01:55) ======

btw. the segfault should be fixed (in r28680) - but the long distance door action is not yet fixed.

sv_send_edicts 1 is not doing anything that I can notice.

====== tlh2000 (2010-02-23 07:13:46) ======

ok, another attempt was made in r28683 - i&#039;m sorry - but i can&#039;t run the game from this machine. so i&#039;m dry swimming here and need your feedback.
====== tlh2000 (2010-02-23 07:14:47) ======

sv_cheats must be activated to use sv_send_edicts - this is printed now
====== markhawrylak (2010-02-23 07:20:23) ======

tested in r28683 the segfault if fixed.
I suggest the defect stays open until defect 2 - &#039;being able to open the door from far away&#039; is resolved.
the sv_send_edicts told me to do the cheats thing and it worked. V cool, this will aid in debugging.
====== tlh2000 (2010-02-23 17:12:23) ======

should be fixed in r28687
====== tlh2000 (2010-02-23 17:32:54) ======

another fix was commited in r28688 - it should fix the situation where you are able to use a door that should be not usable anymore because it was used before and rotation changed the trigger bounding box.
====== markhawrylak (2010-02-24 02:17:16) ======

tested in r28689 - failed
I was still able to open a door from far away, some of the situations are fixed by the change, but I am still able to cause the problem,
====== tlh2000 (2010-02-24 11:34:38) ======

some more work was done in later revisions.
====== markhawrylak (2010-03-05 03:28:41) ======

retested in r28786 - failed
I was still able to open a door from far away.
set status to Open
====== tlh2000 (2010-03-06 14:21:17) ======

can you please provide screenshots of this issue with latest trunk again - i&#039;m not able to reproduce this
====== markhawrylak (2010-03-10 01:54:54) ======

able to use door from a distance
====== markhawrylak (2010-03-10 01:57:26) ======

I have attached a screen shot ufo73.jpg, of the estate map.
1. move your unit to the position as per image 1
2. end your turn
3. move your unit to the position indicated by image 2
4. press backspace (door open/close key) and you are able to control the door from the other side of the room.
====== tlh2000 (2010-04-30 13:28:00) ======

i&#039;ve made another attempt to fix this bug in r29653 - feedback is welcome.
