Witam,
ostatnio mam problem z bytami, mianowicie kod crashuje serwer:

/* Plugin generated by AMXX-Studio */

#include <amxmodx>
#include <amxmisc>

	}

stock bool:fm_is_ent_visible(index, entity, ignoremonsters = 0) {
	new Float:start[3], Float:dest[3];
	pev(index, pev_origin, start);
	pev(index, pev_view_ofs, dest);
	
	xs_vec_add(start, dest, start);

	pev(entity, pev_origin, dest);
	
	engfunc(EngFunc_TraceLine, start, dest, ignoremonsters, index, 0);

	new Float:fraction;
	get_tr2(0, TR_flFraction, fraction);
	
	if(fraction == 1.0 || get_tr2(0, TR_pHit) == entity)
		return true;

	return false;
} 

Skąd wiem że to wina tego pluginu? Długa i żmudna analiza pluginów wskazała na tego słodziaka.

 

A teraz kilka pytań:
1. Czy w tworzeniu bytów istotna jest kolejność przypisywania mu właściwości (classname, origin, wartości int/float/byte itd.)
2. Czy w powyższym kodzie wykonałem coś nie tak, i czemu.

Po pierwsze error logi z debuga daj.

stock StworzEnta(szClassname[] = "info_target", Float:origin[3], Float:takedamage, Float:health, ent_classname[]="", model[]="", solid = SOLID_NOT, Float:mins[3], Float:maxs[3])
{
	new ent = create_entity(szClassname)
	entity_set_origin(ent, origin)
	entity_set_float(ent, EV_FL_takedamage, takedamage)
	entity_set_float(ent, EV_FL_health, health)
	entity_set_string(ent, EV_SZ_classname, ent_classname)
	entity_set_model(ent, model)
	entity_set_int(ent, EV_INT_solid, solid)
	entity_set_size(ent, mins, maxs)
	
	return ent
}

Ta funkcja tworzy enta. Możliwe, że Twój crash nie jest spowodowany tworzeniem enta w sposób nieodpowiedni.
