Question by Pixzle · Jan 17, 2015 at 08:15 PM · c#collisionraycast

Raycasting not hitting and not working in collision and movement script

EDIT: Found the solution. I didn´t know you couldn´t have coordinates as direction. Works just fine now!

Hello guys! I´m currently working on a top down rpg and i just finished the collision script that´s using ray casting in all four directions you can walk in, before translating the player position in that direction. The problem is that it seems like the only ray that´s hitting anything is the one that is checking if there´s a object in front of the player. The one for the left, right and back are not working at all. I hope I´ve given you enough information for you to help me with this problem! Thank you very much!

 using UnityEngine;
 using System.Collections;
 
 public class playerMoveScript : MonoBehaviour {
     int rMove = 0;
     int lMove = 0;
     int fMove = 0;
     int bMove = 0;
     int zMove = 0;
     int xMove = 0;
     float moveSpeed = 7.5f;
 
     void Update () {
         int zMove = rMove + lMove;
         int xMove = fMove + bMove;
         if (xMove != 0 && zMove != 0) {
             transform.Translate(Vector3.forward * Time.deltaTime * xMove * moveSpeed / 1.4f);
             transform.Translate(Vector3.left * Time.deltaTime * zMove * moveSpeed / 1.4f);
         } else {
             transform.Translate(Vector3.forward * Time.deltaTime * xMove * moveSpeed);
             transform.Translate(Vector3.left * Time.deltaTime * zMove * moveSpeed);
         }
         if (Input.GetKey(KeyCode.W)) {
             if (!Physics.Raycast(transform.position,  new Vector3(transform.position.x, transform.position.y, transform.position.z + 2), 2)) {
                 fMove = 1;
             } else {
                 fMove = 0;
             }
         } else {
             fMove = 0;
         }
         if (Input.GetKey(KeyCode.S)) {
             if (!Physics.Raycast(new Vector3(transform.position.x, transform.position.y, transform.position.z - 0.1f),  new Vector3(transform.position.x, transform.position.y, transform.position.z - 2), 2)) {
                 bMove = -1;
             } else {
                 bMove = 0;
             }
         } else {
             bMove = 0;
         }
         if (Input.GetKey(KeyCode.A)) {
             if (!Physics.Raycast(transform.position,  new Vector3(transform.position.x +2, transform.position.y, transform.position.z), 2)) {
                 lMove = 1;
             } else {
                 lMove = 0;
             }
         } else {
             lMove = 0;
         }
         if (Input.GetKey(KeyCode.D)) {
             if (!Physics.Raycast(transform.position,  new Vector3(transform.position.x -2, transform.position.y, transform.position.z), 2)) {
                 rMove = -1;
             } else {
                 rMove = 0;
             }
         } else {
             rMove = 0;
         }
     }
 }

I used coordinates instead of directions. Problem solved.
