Help! Scrags dont attack

Oddly, I've found a bug in my engine. I know its the engine cause I am using stock progs.dat.
plus ive tested with my november version. Which i forked and added protocol 666 to.
If i load up e1m3 the scrags just hover around me and never attack. Any ideas?
Edit: ogres dont attack niether, though the Hell Knight and the zombies do. :roll:
Edit2: Ok something is weird. If I load, -game ITSDEMO (for example havent tried the missionpaks) and then load up
map e1m3 all the monsters act like normal
maybe its a cfg problem....

monsters not attacking sounds like the tracelines to see if the player is actually visible are not impacting on the player. you'll see a similar effect with noclip. monsters will know to attack you but won't think they can hit you so they just run around and don't shoot.

ya thats what i was diggn thru. I only changed the dclipnodes to mclipnodes for sv_move in traceline.
Reverting back didnt help

I'd suggest to grab vanilla progs source and place a handful of dprint()'s in key points of ai.qc and combat.qc (specially FindTarget()). This may give some hint about what's wrong.

welll
Code: Select all
float (entity targ) visible =
{
local vector spot1, spot2;
spot1 = self.origin + self.view_ofs;
spot2 = targ.origin + targ.view_ofs;
traceline (spot1, spot2, TRUE, self); // see through other monsters
if (trace_inopen && trace_inwater)
{
return FALSE; // sight line crossed contents
}
if (trace_fraction == 1)
{
bprint("(trace_fraction == 1)\n");
return TRUE;
}
bprint("visible = FALSE\n");
return FALSE;
};
spams both
trace_fraction == 1
visible = false
over and over when the dog is running in my face
thought it was the clipnodes but reverting back to normal, still nothing. ARrrrggghhh!!

If trace_fraction == 1 when sitting in front a monster then you have something really f*cked up in the engine side.

I think i got it fixed, someting in world.c I just copied the world.c from the stable into the beta... but that doesnt help me understand!

world.c is indeed where the bulk of the traceline code is...

Since apparently you isolated the problem in one single source file, applying a diff between the broken code and the working one is the next logical step to nail the bug.

yes, i might be too pragmatic.
I used the november stable exe by accident.
copied over, without a total rebuild.
so i waaas getting a false positive, as th e nov exe was immune..
BUT
i have a MARCH version post 666 protocol that doesnt have the bug.
digging.
man i shouldnt drink when i work on this kinda shiznit
i'm just a laymen that like to swing the axe, and sometimes my axe gets stuck in a tree-stump

ok after copying 1 file at a time until the march version broke I tracked it down to the sv_cullentities code :/
Code: Select all
qboolean SV_InvisibleToClient(edict_t *viewer, edict_t *seen)
{
int i;
trace_t tr;
vec3_t start;
vec3_t end;
extern trace_t SV_ClipMoveToEntity (edict_t *ent, vec3_t start, vec3_t mins, vec3_t maxs, vec3_t end);
extern qboolean CL_Clip_Test(vec3_t org);
int it;
int vi;
vi = (int)viewer->v.colormap - 1;
if (seen->visibletime[vi] > sv.time)
return false;
Oddly the "player" was constantly becoming culled.
Now i have to clean up all this mess i made >:#
edit:
well im baffled aas if i set (sv_cullentities 0) i still get the BUG
well im just gonna dig a hole and let the topside deal with it,

ok, the world is sane again.
I had a 'culled' field in the edict_t struct, which was really not required.
REmoving it, fixed the bug, and kept my hair intact.
Sheez! Now i can go back and play Sock's new map again....
