Hello!
i am having a problem with my 2D topdown game, i want to make a slime knockback the player, and i can´t do it work like i want to, i want it to knockfrom right to the left, up to down ETC.
but it only knocks from right to left and left to right, i have tried many things i will add the playermovement and the hurtplayer script, also the AI script.
AI:
using UnityEngine;
using System.Collections;
public class AI : MonoBehaviour {
private bool attacking;
public float attackTime;
private float attackTimeCounter;
private Vector3 Player;
private Vector2 Playerdirection;
private float Xdif;
private float Ydif;
private float speed;
private int Wall;
private float distance;
private float distanceFromPlayer;
Rigidbody2D rb;
public float Range = 5;
public float Speed;
Animator anim;
// Use this for initialization
void Start () {
rb = GetComponent ();
Wall = 1 << 8;
speed = Speed;
anim = GetComponent ();
}
// Update is called once per frame
void Update () {
distance = Vector2.Distance (Player, transform.position);
Player = GameObject.Find ("Player").transform.position;
if (distance < Range) {
Xdif = Player.x - transform.position.x;
Ydif = Player.y - transform.position.y;
Playerdirection = new Vector2 (Xdif, Ydif);
if (!Physics2D.Raycast (transform.position, Playerdirection, 5, Wall))
{
rb.AddForce (Playerdirection.normalized * speed);
}
}
}
}
