Trouble coding monsters like Insane in BAND using Q2 Engine

[Ace]

I am trying to get this rat to work, but there is one small issue, using this command in the code: walkmonster_start (self);  CRASHES the game.  I have everythign setup right, only thing is there are only 2 animation modes, walk, and stand!  Is there something I am doing wrong with this code?

OH and there is an H file with the proper animation frame names!

and everythign else seems to be set right in the fgd using worldcraft, and its not teh game, becuase I tested Insane and he worked perfectly, besides missin ghte model, becuase our game don't have that model.  but it was acting and moveing like normal!

Can someone tell me whats wrong... and here is the identifiers as well in spawn.c

{"misc_rat", SP_misc_rat},

void SP_misc_rat (edict_t *self);

and in the fgd file for worldcraft it looks like this...

@PointClass base(Appearflags, Targetname, Target) size(-4 -14 -6, 4

14 6) = misc_rat : "rat1"
[
   spawnflags(Flags) =
   [
      1 : "Ambush" : 0
      2 : "Trigger Spawn" : 0
   ]
   deathtarget(string) : "Entity to trigger at death"
   killtarget(string) : "Entity to remove at death"
   item(string) : "Item to spawn at death"
]

Everything seems to look right, but it crashes the game always on map load...

any ideas without adding new frames, or animations to the rat??

Anyways thsi si driving me nuts!                   

Thanks ahead of the time....

Look in g_monster.c

The walkmonsterstart is what actually spawns that monster. What you are probably doing is either creating an infinite recursive loop or somehow deleting that entity and using it's null reference.


What you want to do is call the actual walking function rat_walk

Although this may also cause an issue. walkmonsterstart is supposed to place the monster into it's walking frames by default.

and how am I supposed to fix this loop?

The walkmonsterstart is what actually spawns that monster.

not really about this walkmonsterstart.... it does not start the spawn process its starts the ai process, becuase when I take it out, he is visable just not animating or moving....

it also drops the character/model to ground if in air, and also removes it from the map if its inside walls or floors, and not in the map itself...

[Ace]

I guess there is not enough coders in the pool of questionary subjects.... so I take no one has a clue as to why this is happening?
