I am trying to make it so that if the player hits a certain section of an NPC, like say the head, something will happen. Otherwise, nothing will happen. I know that cTrace can be used to detect whether the player hits the NPC model anywhere on its body. Is there a way to specify this for only one specific body part of the NPC, like say, the head, rather than the whole body?
For example, if I want to detect whether the player hits a sword on the model, this is what I have done so far:
action NPC_action()
{
...
me = npcPerson;
my.ENEMY_CODE = 7;
...
while(1)
{
...
sword_ctrace();
...
wait(1);
}
...
}
void NPC_Create()
{
npcPerson = ent_create("npcModel.mdl", vector(-64,146,-111),
NPC_action );
...
}
action sword_ctrace()
{
var tip_sword;
var hilt_sword;
...
vec_for_vertex (tip_sword, sword, 54);
vec_for_vertex (hilt_sword, sword, 50);
...
if (c_trace (tip_sword, hilt_sword, IGNORE_ME | IGNORE_PASSABLE) >
0)
{
...
if(you.ENEMY_CODE == 7) // Detects entire NPC model, but not
// specific body part like head.
{
NPC_health -= sword_damage * time_step;
}
...
}
Does anyone know how I can have the sword only detect the head of the NPC, or any other specific bodypart like the arm or leg, rather than the whole body?
