unitattack issue

[Kurofly]

Hello rathena people !
I'm simply trying to make two monsters fight amongst themselves with the following script :

prontera,155,175,4 script test 46,{

mes "[test]";
mes "Je vais invoquer deux monstres et tenter de les faire combattre ."; //I'm gonna spawn 2 mobs and make them fight each other
if (select("ok:non") == 2) end;

@gid1 = monster ("prontera",153,170,"poring",1002,1);
@gid2 = monster ("prontera",155,170,"drops",1113,1);
unitattack @gid1 , @gid2 , 1;
unitattack @gid2 , @gid1 , 1;
}

When the monsters spawn, they run into each other. When they're on the same square they stop and turn into "I don't give a damn" mode, doing what they want again.

 

I already followed this guide to have the GID based functions working and so the unitattack command returns 1(success).

I also downloaded this patch as it seemed to be able to solve my problem but when I compiled my server I got errors (I'm running on rA 17706).

 

If anyone could help me, I'd really appreciate it

I solved my problem

 

If anyone ever wants to make monsters fight amongst themselves, here is what you need in order to do so:

 

 

-open your server folder trunk/src/map/script.c and look for the monster function : 

BUILDIN_FUNC(monster) {

look for this line :

int mobid = mob_once_spawn(sd, m, x, y, str, class_, 1, event, size, ai);

 

then replace it to these :

int mobid = mob_once_spawn(sd, m, x, y, str, class_, 1, event, size, ai);
script_pushint(st,mobid);

 

Now the monster command returns the GID of the monster created

 

-make two monster, one with an IA of 0 and the other with an IA of 1, and save their GID to use it later :

.gid1 = monster ("prontera",153,170,"poring",1002,1,"",0,0);
.gid2 = monster ("prontera",154,170,"drops",1113,1,"",0,1);

You can now use all of the GID based commands and make an epic fight between a poring and a drops

I was also unable to make units attack each other. I got unitwalk and setunitdata working just fine, so it wasn't the GID being messed up.

Monster command already return the gid in $@mobid array

mapreg_setreg(reference_uid(add_str("$@mobid"), i), mobid);

I guess it's simplier to get it directly from the monster command itself but thank you anyway, I'd have saved some time if I had known that .
