Hello everyone,
As the title says, I want to know how can an enemy with NavMesh AI follow ONLY if it sees the player?
Here is the script for the AI:
var speed : float = 10.0;
var player : Transform;
private var dir : Vector3;
private var dirFull : Vector3;
function FixedUpdate()
{
dir = (player.position - transform.position).normalized;
var hit : RaycastHit;
if (Physics.Raycast(transform.position, transform.forward, hit, 1)) // 20 is raycast distance
{
if (hit.transform != this.transform)
{
Debug.DrawLine (transform.position, hit.point, Color.white);
dir += hit.normal * 20; // 20 is force to repel by
}
}
// more raycasts
var leftRay = transform.position + Vector3(-0.125, 0, 0);
var rightRay = transform.position + Vector3(0.125, 0, 0);
if (Physics.Raycast(leftRay, transform.forward, hit, 1)) // 20 is raycast distance
{
if (hit.transform != this.transform)
{
Debug.DrawLine (leftRay, hit.point, Color.red);
dir += hit.normal * 20; // 20 is force to repel by
}
}
// check for rightRay raycast
if (Physics.Raycast(rightRay, transform.forward, hit, 1)) // 20 is raycast distance
{
if (hit.transform != this.transform)
{
Debug.DrawLine (rightRay, hit.point, Color.green);
dir += hit.normal * 20; // 20 is force to repel by
}
}
var rot = Quaternion.LookRotation (dir);
transform.rotation = Quaternion.Slerp (transform.rotation, rot, Time.deltaTime);
transform.position += transform.forward * (2 * Time.deltaTime); // 20 is speed
}
