I can't understand why my cube won't to translate in the fineMovimento (endMovement) vector3 position along Z.
Here the script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MovimentoPorta : MonoBehaviour {
public Transform target;
Vector3 fineMovimento = new Vector3(221.04f, -8.98f,329);
void Update () {
if (Input.GetKeyDown(KeyCode.P))
{
while (target.position != fineMovimento)
{
target.Translate (Vector3.forward*10.0f*Time.deltaTime); //il cubo si doverbbe muovere lungo l'asse Z +
}
}
}
}
Don't use while(...) in void Update() for translate (Because Unity hangs when you press P in play mode). If you want to move to fineMovimento smoothly, one way is to use Vector3.Lerp().
Try this:
public Transform target;
Vector3 fineMovimento;
float smoothTime = 0.125f;
void Start()
{
fineMovimento = target.position; // Initialize
}
void Update ()
{
target.position = Vector3.Lerp(target.position, fineMovimento, smoothTime);
if (Input.GetKeyDown(KeyCode.P))
{
fineMovimento = new Vector3(221.04f, -8.98f,329); // Set end position
}
}
Hope this what you want.

Your problem is likely in the script that translates your bullet.
As the code you shared does exactly what you want. Assuming we are in a front view.
I have verified this by using your script and a copy of the enemy script in place of a bullet that moves them in Vector3.Up direction.
Edit:
You are creating a new vector with the transforms x and 0,5f that gets added every frame.
You either set transform.position or use Translate but with a direction only.
Moves the transform in the direction and distance of translation.
transform.Translate(Vector3 translation)
The following line would work instead.
private void LateUpdate()
{
transform.Translate(Vector3.up * projectile_speed* Time.deltaTime);
}
This is my code does anyone know or can anyone spot why my projectile remains stationary once it's spawned in? the projectile is the prefab shell thanks for your help in advance.

Rigidbody shellRB = shellInstance.GetComponent<Rigidbody>();
shellRB.velocity = 15.0f * fireTransform.forward;
Debug.Log("velocity");
}
}
}
It is also generally discouraged to set the velocity of a rigidbody, but you can use the Rigidbody.AddForce() method to add force to a rigidbody. When you just want add force at the start, you can set the force mode in the function to impulse, like this rb.AddForce(Vector3.forward, ForceMode2D.Impulse);
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TankBehaviour : MonoBehaviour
{
public GameObject shellPrefab;
public Transform fireTransform;
private bool isFired = false;
public float bulletSpeed;
void Update()
{
float x = Input.GetAxis("Horizontal");
float y = Input.GetAxis("Vertical");
transform.position += transform.forward * y;
transform.Rotate(0, x, 0);
if (Input.GetKeyUp(KeyCode.Space) && !isFired)
{
Debug.Log("fire!");
Fire();
}
}
void Fire()
{
//isFired = true;
GameObject shellInstance = Instantiate(shellPrefab, fireTransform.position, fireTransform.rotation) as GameObject;
if (shellInstance)
{
shellInstance.tag = "Shell";
Rigidbody shellRB = shellInstance.GetComponent<Rigidbody>();
shellRB.AddForce(15f * transform.forward, ForceMode.Impulse);
Debug.Log("velocity");
}
}
}
Hope this helps!
The function IncreaseRadius in OrbitFireball script attached to CircleMovementTarget GameObject when called from editProperties Script attached to Radius (+) GameObject does not return the change in values in editor or the original script i.e. OrbitFireball (see on the right in the script OribtFireball, OrbitDistance = 0.1) even when the Console returns the changes just fine (see the console the values increase on hitting the Radius (+) icon).

I'm trying to switch one camera to another to follow the sphere. What's happening in my script is, at first the main camera focuses the ball and as soon as it is grabbed and thrown, the main camera is switched off or disabled and the second camera is enabled to follow the ball when it is in motion. But the second camera doesn't follow in the direction of the ball. Below is the scripts that i implemented.
Note:- I'm attaching the second camera script at run time to second camera.

I am trying to make my enemy object turn and start moving towards my player object when the player comes within a certain vicinity.
For the turning I have been testing the transform.LookAt() function although it isn't returning the desired results as when the player is too close to the enemy object the enemy starts to tilt backwards and I only want my enemy to be able to rotate along the y axis, thanks in advance.
using UnityEngine;
using System.Collections;
public class EnemyController : MonoBehaviour {
public Transform visionPoint;
private PlayerController player;
public Transform Player;
public float visionAngle = 30f;
public float visionDistance = 10f;
public float moveSpeed = 2f;
public float chaseDistance = 3f;
private Vector3? lastKnownPlayerPosition;
// Use this for initialization
void Start () {
player = GameObject.FindObjectOfType<PlayerController> ();
}
// Update is called once per frame
void Update () {
// Not giving the desired results
transform.LookAt(Player);
}
void FixedUpdate () {
}
void Look () {
Vector3 deltaToPlayer = player.transform.position - visionPoint.position;
Vector3 directionToPlayer = deltaToPlayer.normalized;
float dot = Vector3.Dot (transform.forward, directionToPlayer);
if (dot < 0) {
return;
}
float distanceToPlayer = directionToPlayer.magnitude;
if (distanceToPlayer > visionDistance)
{
return;
}
float angle = Vector3.Angle (transform.forward, directionToPlayer);
if(angle > visionAngle)
{
return;
}
RaycastHit hit;
if(Physics.Raycast(transform.position, directionToPlayer, out hit, visionDistance))
{
if (hit.collider.gameObject == player.gameObject)
{
lastKnownPlayerPosition = player.transform.position;
}
}
}
}
change the look at target:
void Update () {
Vector3 lookAt = Player.position;
lookAt.y = transform.position.y;
transform.LookAt(lookAt);
}
this way the look at target will be on the same height as your object.
