Question by PS3_and_PC_Geek · Oct 14, 2013 at 12:38 AM · c#ai

AI in unity, need help

I need some help with my AI I was working on, my code below

 using UnityEngine;
 using System.Collections;
 
 public class NewAITest : MonoBehaviour
 {
     public float motionSpeed = 1f;
     
     void Update()
     {
         // Rays
         Vector3 upRay = transform.TransformDirection(Vector3.forward);
         Vector3 downRay = transform.TransformDirection(Vector3.down);
         
         // Up and down motion
         if(Physics.Raycast(transform.position,upRay,2))
         {
             transform.Translate(Vector3.back *  * Time.deltaTime);
         }
         
         else if(Physics.Raycast(transform.position,downRay,2))
         {
             transform.Translate(Vector3.forward * 1 * Time.deltaTime);
         }
     }
 }

Ask a question!

Also

 Vector3 upRay = transform.TransformDirection(Vector3.forward);

Is it Up or is it Forward?

 Vector3 upRay = transform.TransformDirection(Vector3.forward);

uh, its an orthographic game, it jus looks like its moving up, because the camera is on top of veiw

You mean -Vector3.forward?

forward, up, right etc are all verbal ways of expressing a numerical vector.

0,0,1 = forward (z axis) 0,0,-1 = backward

0,1,0 = up (y axis) 0,-1,0 = down
