Hi i have below cod for my android project and when i look Up and Down and shoot a bullet the bullet shooting direction be wrong where is the problem?
here is a vidoe of my project.

Judging by the video, the problem is that your bullets are fired based on the position and orientation of the camera, not the gun. This is normally preferable in most first person shooter games (eg. Counter-Strike and similar), but maybe not in your case (since you're using mobile joystick controls).
This behavior is caused by the following code:
var b:Rigidbody=Instantiate(bullet,this.transform.position,this.transform.rotation);
b.AddForce(this.transform.forward*Speed);
Since you're using the position and rotation of this.transform, the script refers to the transform of the camera you attached the script to.
If you wish your game to behave differently, you should consider referring to the transform component of the gun instead (conveniently, in your cased stored in the variable gun):
var b:Rigidbody=Instantiate(bullet,gun.transform.position,gun.transform.rotation);
b.AddForce(gun.transform.forward*Speed);
Note that this might not work if your gun's anchor isn't at the muzzle and its forward vector doesn't point in the direction you want the bullet to come out. In that case, you might want to add to the gun an empty child GameObject that's properly positioned and oriented.

I'm having troubles with my enemy NavMeshAgent AI, First it searches for GameObjects tagged with "Defenses", then I set the first destination based in how close the defense is by my enemy, when the defense is destroyed, the array value is increased by one and it changes the destination to the next defense.
My problem is, my player can create (Instance) new defenses during the game, when all my defenses are destroyed, my enemy turns crazy, so, i need a way to add those new defenses to my array, below is my enemy script.
public class NavMeshEnemy : MonoBehaviour
{
[Header("References", order = 0)]
[SerializeField] NavMeshAgent enemyAgent;
[Space(10)]
[SerializeField] GameObject[] destinations;
[Space(10)]
[SerializeField] float distanceObjects;
[SerializeField] int arrayElements = 0;
void Awake()
{
enemyAgent = GetComponent<NavMeshAgent>();
destinations = GameObject.FindGameObjectsWithTag("Defenses");
}
void Start()
{
destinations = destinations.OrderBy((d) => (d.transform.position - this.transform.position).sqrMagnitude).ToArray();
}
void Update()
{
distanceObjects = Vector3.Distance(this.transform.position, destinations[arrayElements].transform.position);
enemyAgent.destination = destinations[arrayElements].transform.position;
CheckArray();
}
void CheckArray()
{
if (destinations[arrayElements].gameObject.activeInHierarchy == false)
{
if (arrayElements < destinations.Length - 1)
{
arrayElements++;
enemyAgent.destination = destinations[arrayElements].transform.position;
}
else
{
arrayElements = 0;
}
}
}
}
Thank you for reading! :)
I would rather implement a component on your prefab with a static list like e.g.
public class NavMeshDestination : MonoBehaviour
{
public static HashSet<Transform> existingDestinations = new HashSet<Transform>();
private void Awake()
{
if(!existingDestinations.Contains(this)) existingDestinations.Add(this);
}
private void OnDestroy()
{
if(existingDestinations.Contains(this)) existingDestinations.Remove(this);
}
}
And then don't even go by tag but simply do
public class NavMeshEnemy : MonoBehaviour
{
[Header("References", order = 0)]
[SerializeField] NavMeshAgent enemyAgent;
[Space(10)]
[SerializeField] float distanceObjects;
[SerializeField] int arrayElements = 0;
void Awake()
{
if(!enemyAgent) enemyAgent = GetComponent<NavMeshAgent>();
}
void Update()
{
destinations = NavMeshDestination.existingDestinations.OrderBy(d => (d.transform.position - this.transform.position).sqrMagnitude).ToArray();
distanceObjects = Vector3.Distance(this.transform.position, destinations[arrayElements].transform.position);
enemyAgent.destination = destinations[arrayElements].transform.position;
CheckArray();
}
void CheckArray()
{
if (destinations[arrayElements].gameObject.activeInHierarchy == false)
{
if (arrayElements < destinations.Length - 1)
{
arrayElements++;
enemyAgent.destination = destinos[arrayElements].transform.position;
}
else
{
arrayElements = 0;
}
}
}
}
Note however that this still won't fix your issues with no available destination. So you probably should stop the execution if the array is empty like
if(NavMeshDestination.existingDestinations.Count == 0)
{
// Stop the enemyAgent
return;
}
Trying to run a raycast from my camera to Z = 0 that will hit objects on the TransparentFX layer and temporarily make them transparent as they are likely blocking the view of the player. But the raycast never hits anything.

Figured it out. I was using RaycastHit2D and Physics2D.RaycastAll, which uses Vector2 parameters so the Z forward variable was being taken out of the equation. Switched up to Box Collider and Physics.RaycastAll and it works great.
I was trying to achieve this kind of player ball movement:
Catch Up (Ketchapp)
From my side I have tried and record a video of my current implementation:
CatchUpBallMovementDemo
Two kinds of problem, I was facing:
ball making so much jerk while moving on the plain track that I hope you have clearly noticed in my recorded video
when ball reach left or right edge and you try to swipe its making jerk again rather than remain restricted because clamping related code already added
I have just created a demo project so here I am providing the link for it so personally you can check and provide me a suggestion for making ball movement perfect.
Demo Project Source Link: CatchUpBallDemo
Demo Project SIZE 20MB
What at present making jerk in ball movement that I can't able to decide, whether its following camera jerk, whether ball not moving properly though I have created a plain track for checking purpose.

Complete code added within the working demo project. Share your suggestions with me to solve this.

I could solve the second problem by simply adding this to BallController.ClampingBallMovement():
private void ClampingBallMovement ()
{
Vector3 currRigidbodyPos = myRigidBody.position;
if (currRigidbodyPos.x <= -ballHorzRange || currRigidbodyPos.x >= ballHorzRange) {
currRigidbodyPos.x = Mathf.Clamp (currRigidbodyPos.x, -ballHorzRange, ballHorzRange);
myRigidBody.position = currRigidbodyPos;
}
// I ADDED THIS
// Clamp the velocity as well
if (currRigidbodyPos.x <= -ballHorzRange && myRigidBody.velocity.x < 0 || currRigidbodyPos.x >= ballHorzRange && myRigidBody.velocity.x > 0)
{
myRigidBody.velocity = new Vector3(0, myRigidBody.velocity.y, myRigidBody.velocity.z);
}
}
you clamped the position but did not clamp the velocity as well.
I could not reproduce the first jerking arround on my PC.

For a quick explanation of my code: I have an array of size 5. It holds the obstacles that I have created. When deciding what to put inside the array, I generated a random number (1 or 2). If it's a 1, I put in a column. If it's a 2, I put in a ball. These obstacles are spawned off-screen. Then, I move them in the actual scene after using random number to determine the X position.
This part in particular is where I try to implement it:
if (obstacles[currentObstacle].transform.tag == "Ball")
{
spawnXPosition = Random.Range(9f, 10f);
obstacles[currentObstacle].transform.position = new Vector2(spawnXPosition, -1.84f);
ballPrefab.GetComponent<Rigidbody2D>().AddForce(new Vector2(-100f, 0) * 5);
beforeBall = true;
}
I may have some remnants of stuff that I have been testing out, so some of the code may seem redundant and messy.
I also tried using Translate and Velocity with no success. I also have a ScrollingObject code and a RepeatingBackground code. I placed the ScrollingObject code in the Ball prefab too. (Also, tried taking it out -> ball rolls to the right). These codes come from the Unity tutorial.
RepeatingBackground:
public class RepeatingBackground : MonoBehaviour {
private BoxCollider2D groundCollider;
private float groundHorizontalLength;
// Use this for initialization
private void Awake () {
groundCollider = GetComponent<BoxCollider2D>();
groundHorizontalLength = groundCollider.size.x;
}
// Update is called once per frame
private void Update () {
if (transform.position.x < -groundHorizontalLength)
{
RepositionBackground();
}
}
private void RepositionBackground()
{
Vector2 groundOffSet = new Vector2(groundHorizontalLength * 2f, 0);
transform.position = (Vector2)transform.position + groundOffSet;
}
}
ScrollingObjects:
public class ScrollingObject : MonoBehaviour {
private Rigidbody2D rb2d;
// Use this for initialization
void Start () {
rb2d = GetComponent<Rigidbody2D>();
rb2d.velocity = new Vector2(GameControl.instance.scrollSpeed, 0);
}
// Update is called once per frame
void Update () {
if (GameControl.instance.gameOver == true)
{
rb2d.velocity = Vector2.zero;
}
}
}
It looks like you simply named the wrong object in your first example.
if (obstacles[currentObstacle].transform.tag == "Ball")
{
spawnXPosition = Random.Range(9f, 10f);
obstacles[currentObstacle].transform.position = new Vector2(spawnXPosition, -1.84f);
ballPrefab.GetComponent<Rigidbody2D>().AddForce(new Vector2(-100f, 0) * 5);
beforeBall = true;
}
Notice how here you added the force to the prefab, not an instantiated version of the prefab.
I played around a bit more and got it to work. I just wrote another script that added force to the object. I still do not understand why my original way did not work though.
I am currently building my first multiplayer game in unity and having a little bit of an issue changing/transmitting the players direction over the network.
My current player controls class is this:
using UnityEngine;
using System.Collections;
public class playerControls : MonoBehaviour {
#region
//Vars
//Movements Vars
public float runSpeed;
Rigidbody mybody;
Animator myAnimator;
bool playerDirectionE;
#endregion
// Use this for initialization
void Start () {
mybody = GetComponent<Rigidbody>();
myAnimator = GetComponent<Animator>();
playerDirectionE = true;
mybody.transform.eulerAngles = new Vector3(0, 90, 0);
}
// Update is called once per frame
void Update () {
}
void FixedUpdate()
{
float move = Input.GetAxis("Horizontal");
myAnimator.SetFloat("speed", Mathf.Abs(move)); //To intiate the charecter transition(move)
mybody.velocity = new Vector3(move * runSpeed, mybody.velocity.y, 0); //move charecter along the x axis, and keep y on gravity, not touching the z axis
if(move>0 && !playerDirectionE)
{
Flip();
}
else if(move<0 && playerDirectionE)
{
Flip();
}
}
void Flip()
{
playerDirectionE = !playerDirectionE;
Vector3 theScale = transform.localScale;
theScale.z *= -1;
transform.localScale = theScale;
}
}
I am using the following client information to send commands over the network:
using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
using System.Collections.Generic;
public class PlayerSyncRotation : NetworkBehaviour {
[SyncVar(hook ="OnPlayerRotSynced")]
private float syncPlayerRotation;
[SerializeField]
private Transform playerTransform;
private float lerpRate = 15;
private float lastPlayerRot;
private float threshold = 1;
private List<float> syncPlayerRotList = new List<float>();
private float closeEneough = 0.3f;
[SerializeField]
private bool userHistoricalInterpolation;
[Client]
void OnPlayerRotSynced(float latestPlayerRotation)
{
syncPlayerRotation = latestPlayerRotation;
syncPlayerRotList.Add(syncPlayerRotation);
}
[Command]
void CmdProvideRotationsToServer(float playerRot)
{
syncPlayerRotation = playerRot;
}
[Client]
void transmitRotations()
{
if (isLocalPlayer)
{
if(CheckIfBeyondThreshold(playerTransform.localScale.z, lastPlayerRot)){
lastPlayerRot = playerTransform.localScale.z;
CmdProvideRotationsToServer(lastPlayerRot);
}
}
}
bool CheckIfBeyondThreshold(float rot1, float rot2)
{
if (Mathf.Abs(rot1 - rot2) > threshold)
{
return true;
}
else
{
return false;
}
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
lerpRotation();
}
void FixedUpdate()
{
transmitRotations();
}
void lerpRotation()
{
if (!isLocalPlayer)
{
HistoricalInterpolation();
}
}
void HistoricalInterpolation(){
if (syncPlayerRotList.Count > 0)
{
LerpPlayerRotation(syncPlayerRotList[0]);
if(Mathf.Abs(playerTransform.localEulerAngles.z - syncPlayerRotList[0]) < closeEneough)
{
syncPlayerRotList.RemoveAt(0);
}
Debug.Log(syncPlayerRotList.Count.ToString() + "syncPlayerRotList Count");
}
}
void LerpPlayerRotation(float rotAngle)
{
Vector3 playerNewRot = new Vector3(0, 0, rotAngle);
playerTransform.rotation = Quaternion.Lerp(playerTransform.rotation, Quaternion.Euler(playerNewRot),lerpRate*Time.deltaTime);
}
}
My rotation looks fine on the client, but over the network on the second client, the rotation is broken and looks very wrong.
I have attached a link to a Webm where you can see the short video snippet of my problem HERE.
Would anyone here have any input as to what I could be doing wrong or how I could fix this issue? any suggestions would be appreciated.
Instead Using your custom code, i will like to say you that use Unet NetworkTransform. It is Unet high level API with different option of customization.
A component to synchronize the position and rotation of networked
objects(more).
Unet HLAPI are open source so you can also get the coding of the networkTransform at bitbucket.
