Hello I’ve been working on a freelancer or freespace style game and I’ve programmed a basic Ai movement script but I don’t know if it’s the right way to do it… It’s my first time programming something like that…
Here is what I’ve got so far : https://sites.google.com/site/dimitrijejankov/3d-space-shooter The movement script uses a modified version of the boids algorithm…
Here is the source :
using UnityEngine;
using System.Collections;
[RequireComponent(typeof (Rigidbody))]
public class EnemyMovement : MonoBehaviour {
public Transform target;
Vector3 acceleration;
Vector3 velocty;
float speed = 5.0f;
GameObject[] boids;
// Use this for initialization
void Start () {
boids = GameObject.FindGameObjectsWithTag("Enemy");
//velocty = (target.position - transform.position).normalized * speed;
}
// Update is called once per frame
void Update () {
Vector3 r1 = Rule_1();
Vector3 r2 = Rule_2();
Vector3 r3 = Rule_3();
acceleration = r1 + r2 + r3;
velocty += 2 * acceleration * Time.deltaTime;
if(velocty.magnitude > speed)
velocty = velocty.normalized * speed;
rigidbody.velocity = velocty;
Quaternion desiredRotation = Quaternion.LookRotation(velocty);
transform.rotation = Quaternion.Slerp(transform.rotation,desiredRotation,Time.deltaTime * 3);
}
Vector3 Rule_1(){
Vector3 distance = target.position - transform.position;
if(distance.magnitude < 3)
return distance.normalized * -12;
else
return distance.normalized * 2;
}
Vector3 Rule_2(){
if(!Physics.Raycast(transform.position,transform.forward,2.0f)){
return -transform.up ;
}
return Vector3.zero;
}
Vector3 Rule_3(){
Vector3 c = Vector3.zero;
foreach (GameObject g in boids){
if(g.transform.position != transform.position){
if((g.transform.position - transform.position).magnitude < 1.0f)
{
c -= (g.transform.position - transform.position);
}
}
}
return c * 3.0f;
}
}
Any kind of help would be great
