Translate, Rotate & LookAt in C# for Unity

I learned about Translate, Rotate & LookAt in Unity…

11th Programs:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TestScript : MonoBehaviour
{
    float _moveSpeed = 7f;
    float _rotateSpeed = 200f;

    void Update()
    {
        if (Input.GetKey(KeyCode.UpArrow))
        {
            gameObject.transform.Translate(new Vector2(0f, _moveSpeed) * Time.deltaTime, Space.Self);

        else if (Input.GetKey(KeyCode.LeftArrow))
        {
            gameObject.transform.Rotate(new Vector3(0f, 0f, _rotateSpeed) * Time.deltaTime, Space.Self);
        }

        else if (Input.GetKey(KeyCode.RightArrow))
        {
            gameObject.transform.Rotate(new Vector3(0f, 0f, -_rotateSpeed) * Time.deltaTime, Space.Self);
        }
    }
}

From above program:

if (Input.GetKey(KeyCode.UpArrow))
{
gameObject.transform.Translate(new Vector2(0f, _moveSpeed) * Time.deltaTime, Space.Self);
}

• If we don’t use Time.deltaTime then the gameObject will move so fast because of higher framerate…
• If we don’t use Space.Self then as a default it is going to move around the local space of the gameObject…
• Space.Self → It will help gameObject to move all around in the space…

else if (Input.GetKey(KeyCode.LeftArrow))
{
gameObject.transform.Rotate(new Vector3(0f, 0f, _rotateSpeed) * Time.deltaTime, Space.Self);
}

• Rotate cuz now we need not to move the object…we need to rotate…

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TestScript2 : MonoBehaviour
{
    [SerializeField] Transform target;
    Vector2 lastRotation;

    void Update()
    {
        Vector2 direction = target.position - transform.position;

        if (lastRotation != direction)
        {

        transform.rotation = Quaternion.FromToRotation(Vector3.up, direction);
            Debug.Log("test");
        }
        lastRotation = direction;
    }
}

From above program:

Vector2 direction = target.position - transform.position;

• This will say the gameObject at which it is attached to to rotate at a certain direction based on the offset…

transform.rotation = Quaternion.FromToRotation(Vector3.up, direction);

• new Vector3(0, 1, 0) === Vector3.up/down/ left/right/ back/forward
• Rotates the gameObject from a certain location to a new location…

That’s all…Thank you for reading😉:)
