Problem Vector3.transform (C#)

It is unclear where your problem is. The code above looks fine. It will move the object towards positive 'z' at the rate of 1 unit per second as long as the key is held down. A single click will only move it a small (and perhaps unnoticeable) distance . So maybe your scale is too big and 1 unit per second is doesn't show, or maybe you are using an orthographic camera, or maybe you are expecting a click to move it, or maybe the script is disabled, or....

If you are rotating this object, you can cause it to move in the direction of rotation by replacing Vector3.forward with transform.forward.

Now i have the problem whereby my character keeps falling through the floor and i have lost the functionality of the left and back keys as there is only: transform.forward/right. No left or back?

By fall, i mean there is no sense of gravity so if i look upwards my character will move upwards and start floating, and if i look downwards my character will go through the floor.

Assu$$anonymous$$g you are walking on the XZ plane, it sounds like you need to remove the 'y' component from your movement vector. Something like:

 Vector3 dir = transform.forward;
 dir.y = 0.0;
 dir.Normalize();
 transform.position += dir * Time.deltaTime * speed;

Note I've added 'speed' here which you don't need if you are happy with your current speed. 'speed' is a variable you define or can be replaced by a constant.

I see, where exactly do i put that code? This is what i have so far.

 using UnityEngine;
 using System.Collections;
 
 public class character$$anonymous$$ovement : $$anonymous$$onoBehaviour {
     
     // Update is called once per frame
     void Update () {
 
         if(Input.Get$$anonymous$$ey($$anonymous$$eyCode.W)){
             gameObject.transform.position += transform.forward * Time.deltaTime;
         }
 
         Vector3 dir = transform.forward;
         dir.y = 0.0;
         dir.Normalize();
         transform.position += dir * Time.deltaTime;
 
     }
 }

But i keep getting errors when i try to play it, Do i create a new C# script? Also, If my terrain has slopes and stuff or if i want my character to Jump, do i not need the Y axis enabled?

See that this is C#, not Javascript/Unityscript, you need to add an 'f' to the end of 0.0:

  dir.y = 0.0f;

For any future posts, it is really helpful if you include a copy of the error you are getting in the console for any compile-time errors.

Ah damn yeah, i failed to see that. Thanks for the help.
