About AI detecting a sound
Hello! I'm trying to make AI detecting a sound. I kinda know how it works. But can't make it on C# Script.
My idea is I use Raycast and if the sound is made, it will caculate the distance between AI and the sound. If the distance is =<10f, the AI will follow the sound.
I'm not use to making script with Raycast and I really need help. Someone Please help me.
Why don't you use triggers instead? Put a sphere trigger around the sound source. When the sound is emitted, all the ennemies inside the trigger will be notified.
// Set up a list to keep track of targets
public List targets = new List();
// If a new enemy enters the trigger, add it to the list of targets
void OnTriggerEnter(Collider other){
if (other.CompareTag("Enemy")) {
GameObject go = other.gameObject;
if(!targets.Contains(go)){
targets.Add(go);
}
}
}
// When an enemy exits the trigger, remove it from the list
void OnTriggerExit(Collider other){
if (other.CompareTag("Enemy")) {
GameObject go = other.gameObject;
targets.Remove(go);
}
}
public void EmitSound()
{
// Play your sound
// ...
for( int i = 0 ; i < targets.Count ; ++i)
{
targets[i].GetComponent<EnemyScript>().FollowMe( transform ) ;
}
}
Thx. But with this idea, the sound will go through the wall.. I don't want the sound to go through the wall.
Then, simply cas a ray inside the loop when sound is emitted to check whether the ennemy is not behind an obstacle before calling the desired function.
