0001693: Problem with CanSeeLOSFlag - SphereServer BugTracker

Notes
(0000341) nolok (reporter) 22-12-09 10:51 edited on: 22-12-09 12:01	Now it works, but only if i use this: <SRC.CANSEELOSFLAG 020\|040\|080,<UID>> If i use: <CANSEELOSFLAG 020\|040\|080,<SRC.UID>>, it doesn't work. I think it's strange, because in the sphere.ini the AdvancedLos flag is set to 03 :P // Uses the new LoS algorithm // ADVANCEDLOS_DISABLED 0x00 // Disabled, use the old method // ADVANCEDLOS_PLAYER 0x01 // Enabled only for players // ADVANCEDLOS_NPC 0x02 // Enabled only for NPCs AdvancedLos=03 EDIT: It works even if AdvancedLos setted to 0, it's a bug or it's wanted? I remember nazghul wrote that should not work without this flag, because canseelosflag uses new algorithms and so on :P EDIT 2: If i am in gm mode, canseelosflag returns always 1, and it's correct. But, with any flag (also with 0, and with this flag it should return always 1, because i dont't set any block to the los), without the gm mode, it still returns zero :( (this time advancedlos is set to 03)

(0000345) MrSugarCube (administrator) 02-01-10 04:30	With AdvancedLos disabled, CANSEELOSFLAG will still 'work' but the flags will be ignored (basically functions the same as CANSEELOS would). As far as I can tell, without the flags (or flags=0), normal LOS checks will take place, so a wall would cause the function to return 0 unless the appropriate 'no-block' flags have been passed in.

(0000346) nolok (reporter) 02-01-10 18:58	I tried also with all no-block flags, and i am really near the npc or above it. This function doesn't work, since i have AdvancedLOS=03 and no walls or any type of obstacles between us.

(0000402) HOCOK (reporter) 11-03-10 18:48	CanSeeLosFlag works incorrect. NPC\|Rock\|Player ------------------------- Troll\|0136d\|Player All flags returning: 1

(0000854) MrSugarCube (administrator) 22-01-11 02:56	I still can't see anything wrong with the way CANSEELOSFLAG works - is this still an issue on the latest builds? Here's a function which may help if you can find a location where you believe the flags don't work correctly. When you use this function a number of tiles are created around your character coloured blue or red to indicate the result of CANSEELOSFLAG (blue=can see, red=cannot see). // // Usage: F_TestLos <Flags> <Distance=8> <Time=10> // Flags = flags to pass to CANSEELOSFLAG (default 0) // Distance = distance to show los (default 8) // Time = time before items decay (default 10) // [FUNCTION f_testlos] IF (<ISGM>) SYSMESSAGE Please switch off GM mode before using this function. RETURN ENDIF LOCAL.FLAGS = <ARGN1> LOCAL.DIST = <ARGN2> LOCAL.TIME = <ARGN3> IF !(<LOCAL.DIST>) LOCAL.DIST = 8 ENDIF IF (<LOCAL.TIME> < 1) LOCAL.TIME = 10 ENDIF FOR x -<LOCAL.DIST> <LOCAL.DIST> FOR y -<LOCAL.DIST> <LOCAL.DIST> LOCAL.PX = <EVAL <P.X> + <LOCAL.X>> LOCAL.PY = <EVAL <P.Y> + <LOCAL.Y>> IF (<CANSEELOSFLAG <LOCAL.FLAGS>, <dLOCAL.PX>,<dLOCAL.PY>,<P.Z>,<P.MAP>>) LOCAL.HUE = 02 LOCAL.CANSEE += 1 ELSE LOCAL.HUE = 022 ENDIF SERV.NEWITEM i_rune_alchem_4 REF1 = <NEW.UID> REF1.COLOR = <LOCAL.HUE> REF1.TYPE = t_normal REF1.ATTR = attr_decay REF1.TIMER = <LOCAL.TIME> REF1.P <dLOCAL.PX>,<dLOCAL.PY>,<P.Z>,<P.MAP> LOCAL.COUNT += 1 ENDFOR ENDFOR SYSMESSAGE Can see <dLOCAL.CANSEE>/<dLOCAL.COUNT> tiles. RETURN

(0000855) MrSugarCube (administrator) 22-01-11 03:07	When AdvancedLos is enabled the height of objects is taken into consideration, therefore I would expect CANSEELOS/CANSEELOSFLAG to return 1 for the Troll-Rock-Player example. In the default script pack the player (height=16) can see over the rock (height=2) to view the troll (height=23).
