move a gameobject unity 3d code example

Example 1: how to make an object move in unity

Vector3 input = new Vector3 (Input.GetAxis("Horizontal"), 0 , Input.GetAxis("Vertical");
Vector3 dir = input.normalized;
Vecotr3 vel = dir * speed * Time.deltaTime;

transform.Translate(vel);

Example 2: unity how to move a gameobject towards another gameobject

// the script has been edited a little but is still very similar to the original post
	public float speed;
	public GameObject object1; // The game object that moves.
	public GameObject object2; // the game object that Object 1 moves to.

	void FixedUpdate()
	{
		// Calculate direction vector.
		Vector3 dirction = object1.transform.position - object2.transform.position;

		// Normalize resultant vector to unit Vector.
		dirction = -dirction.normalized;

		// Move in the direction of the direction vector every frame.
		object1.transform.position += dirction * Time.deltaTime * speed;
	}

Example 3: translate gameobject unity c#

using UnityEngine;
using System.Collections;public class ExampleClass : MonoBehaviour
{
    void Update()
    {
        // Move the object forward along its z axis 1 unit/second.
        transform.Translate(Vector3.forward * Time.deltaTime);        // Move the object upward in world space 1 unit/second.
        transform.Translate(Vector3.up * Time.deltaTime, Space.World);
    }
}
