On input left click (Fire1), the projectile spawns from the projectileSpawn position. On right click(Fire2), I want to have the projectile shoot "in reverse" and start from the projectileSpawnTwo position and back to the initial projectileSpawn location. It currently shoots forward but I want the projectile to spawn back to an exact position.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerWeapon : MonoBehaviour
{
public GameObject projectilePrefab;
public GameObject projectileTwoPrefab;
public Transform projectileSpawn;
public Transform projectileSpawnTwo;
public float projectileSpeed = 30;
void Update ()
{
if (Input.GetButtonDown("Fire1"))
{
Fire();
}
if (Input.GetButtonDown("Fire2"))
{
Fire2();
}
}
private void Fire()
{
GameObject projectile = Instantiate(projectilePrefab);
Physics.IgnoreCollision(projectile.GetComponent<Collider>(),
projectileSpawn.parent.GetComponent<Collider>());
projectile.transform.position = projectileSpawn.position;
var rot = projectile.transform.rotation.eulerAngles;
projectile.transform.rotation = Quaternion.Euler(rot.x, transform.eulerAngles.y, rot.z);
projectile.GetComponent<Rigidbody>().AddForce(projectileSpawn.forward * projectileSpeed, ForceMode.Impulse);
}
private void Fire2()
{
GameObject projectile = Instantiate(projectileTwoPrefab);
Physics.IgnoreCollision(projectile.GetComponent<Collider>(),
projectileSpawnTwo.parent.GetComponent<Collider>());
projectile.transform.position = projectileSpawnTwo.position;
var rot = projectile.transform.rotation.eulerAngles;
projectile.transform.rotation = Quaternion.Euler(rot.x, transform.eulerAngles.y, rot.z);
projectile.GetComponent<Rigidbody>().AddForce(projectileSpawnTwo.forward * projectileSpeed, ForceMode.Impulse);
}
}
Since both methods are very similar to generalize your method a bit you could do
private Collider projectileSpawnParentCollider;
privtae enum FireType
{
One,
Two
}
private void Awake()
{
// this hould probably done only once to be more efficient
projectileSpawnParentCollider = projectileSpawn.parent.GetComponent<Collider>();
}
private void Update()
{
if (Input.GetButtonDown("Fire1"))
{
Fire(FireType.One);
}
if (Input.GetButtonDown("Fire2"))
{
Fire(FireType.Two);
}
}
private void Fire(FireType fireType)
{
var position = fireType == FireType.One ? projectileSpawn.position : projectileSpawnTwo.position;
var rot = projectile.transform.rotation.eulerAngles;
var rotation = Quaternion.Euler(rot.x, transform.eulerAngles.y, rot.z);
// pass the position and rotation alraedy
GameObject projectile = Instantiate(projectilePrefab, position, rotation);
Physics.IgnoreCollision(projectile.GetComponent<Collider>(), projectileSpawnParentCollider);
var forceDirection = fireType == FireType.One ? projectileSpawn.forward : (projectileSpawn.position - projectileSpawnTwo.position).normalized;
projectile.GetComponent<Rigidbody>().AddForce(forceDirection * projectileSpeed, ForceMode.Impulse);
}
The
projectileSpawn.position - projectileSpawnTwo.position
returns a Vector pointing from projectileSpawnTwo.position towards projectileSpawn.position. Using normalized returns a vector with the same direction but with magnitude = 1.
However, note that this only works ofcourse if the player is not moving after the second shoot. If the player can move you should probably rather implement another component for making the bullet object actually follow the player position.
You could use Quaternion.LookRotation and Rigidbody.MoveRotation to write a separate component like e.g.
public class FollowPlayer : MonoBehaviour
{
public Transform PlayerTransform;
public RigidBody rigiBody;
public speed;
private void Awake()
{
rigidBody = GetComponent<RigidBody>();
}
private void LateUpdate()
{
if(!PlayerTrasnform) return;
var rotation = Quaternion.LookRotation(PlayerTransform.position - transform.position, Vector3.up);
rigidBody.MoveRotation(rotation);
rigidBody.velocity = (PlayerTransform.position - transform.position).normalized * speed;
}
}
and in your script add the component in case two like
private void Fire(FireType fireType)
{
var position = fireType == FireType.One ? projectileSpawn.position : projectileSpawnTwo.position;
var rot = projectile.transform.rotation.eulerAngles;
var rotation = Quaternion.Euler(rot.x, transform.eulerAngles.y, rot.z);
// pass the position and rotation alraedy
GameObject projectile = Instantiate(projectilePrefab, position, rotation);
Physics.IgnoreCollision(projectile.GetComponent<Collider>(), projectileSpawnParentCollider);
if(fireType == FireType.One)
{
projectile.GetComponent<Rigidbody>().AddForce(projectileSpawn.forward * projectileSpeed, ForceMode.Impulse);
}
else
{
var follow = projectile.AddComponent<FollowPlayer>();
follow.speed = projectileSpeed;
follow.PlayerTransform = YourPlayerTransform; // or probably projectileSpawn
}
}
Note: Typed on smartphone so no warrenty but I hope the idea gets clear.

So I'm making a clone of Crossy Roads where the camera follows the player. It does some linear interpolation (Lerp) after moving, and the camera starts moving away from the player in the positive direction (x-axis until camera reaches to a certain range where player is not visible enough). Things I have tried is by flagging it, but I think I'm doing it wrong.
Problem
I have done my camera movements accordingly, but I am having an issue where the conditions are not properly met. I'm get the offset camera after not moving, but it does not the Lerp, and vice-versa. I want both to happen after a certain condition after the game starts. When the player moves, the camera follows it in Lerp. However, once the player is "Idle", its still Lerping. I want the camera to continue by itself and at the same time focus at the player's object.
Example
Camera with Lerp, but not moving away from the player
Camera moving away, but not following player with lerp

Some help would be appreciate it. I feel I have been staring at this problem and I bet it is something minimal and small from just thinking it.
Let me know if you need clarifications. I'm happy to edit and answer them for everyone
If player in your game does not change, you don't have to find the player reference in each LateUpdate().
I notice that once stillIdle is set true, it never goes back to false, is this your intention to do that?
You call Lerp when playerControlScript.GetfirstInput() is true, so maybe we need to look at its implementation. Maybe it turns true in some conditions you do not intend it to.
Maybe Try this
public class PlayerControl : MonoBehaviour
{
private bool _hasFireFirstInput = false;
private bool _isIdle = true;
public bool IsIdle => _isIdle;
public bool HasFireFirstInput => _hasFireFirstInput;
private void Update()
{
if (Input.GetButton("Horizontal") || Input.GetButton("Vertical"))
{
_hasFireFirstInput = true;
_isIdle = false;
Vector3 pos = transform.position;
pos = new Vector3(pos.x, pos.y, pos.z + .2f * Time.deltaTime);
transform.position = pos;
}
else
{
_isIdle = true;
}
}
}
I use Input.GetButton() rather than Input.GetButtonDown(), since the later only return true at the frame the button is pressed, meaning that if i long-press the button, it will return false after the next frame.
public class CameraController : MonoBehaviour
{
[SerializeField] PlayerControl _playerControlScript;
[SerializeField] Vector3 _offset;
[SerializeField] float _lerpSpeed;
bool _iskeepLerping = false;
float _lerpVal = 0f;
private void LateUpdate()
{
if (!_playerControlScript.HasFireFirstInput)
{
return;
}
if (_playerControlScript.IsIdle)
{
MoveAway();
}
else
{
Lerp();
}
}
private void MoveAway()
{
_iskeepLerping = false;
transform.position = new Vector3(transform.position.x + 0.69f * Time.deltaTime, transform.position.y, transform.position.z);
}
private void Lerp()
{
if (!_iskeepLerping)
{
_lerpVal = 0f;
}
Vector3 newCameraPos = Vector3.Lerp(transform.position, _playerControlScript.transform.position + _offset, _lerpVal);
transform.position = newCameraPos;
_lerpVal += _lerpSpeed * Time.deltaTime;
_iskeepLerping = true;
}
}
I made a Gun Script (using YT videos) and a Bullethole GameObject should Instantiate at the Position the RayCast hits an Object. But it is always at 0 0 0. I tried many thing but non work.

You're not hitting anything. You check to see if you hit something, and then spawn a bullet hole even if you didn't hit anything.
If you didn't hit anything, there isn't anywhere to put a bullet hole.
The problem is that you're using the raycast hit as a local variable, which allows you to use it outside of the scope where it's actually valid.
Delete rayHit from your class and define it in the raycast instead, like
out RaycastHit rayHit
then it should only be scoped for the if statement and you'll get a compiler error anywhere it's not valid.
This brings up a larger question about what do you do if it misses an enemy, or which layers you should be raycasting against. Personally I think you'd want to raycast against everything, then you can try to determine what you hit and what that means later. Only other really good alternative would be to raycast against enemies, then repeat that against objects if that misses, but it's a lot of overhead to keep spinning up the raycasting engine. You'd be better off firing against multiple layers and getting the layer off the collider.
PS too your spread is probably way, way too big. For values of spread, 0.01 is half a degree, 0.1 is five degrees, 1 is 45 degrees.
I found the Problem. Just tell the Gun that the Layer "Ground" is also an Enemy. Now it works. Thanks
Basically you need to Transform Direction e.g camTrans.TransformDirection. You can try this way
public class Raytest : MonoBehaviour
{
public Camera fpsCam;
public float maxDistance = 200f;
public bool update = true;
public GameObject objectToSpawn;
private void Update()
{
if(!update) return;
var camTrans = fpsCam.transform;
if (Physics.Raycast(camTrans.position, camTrans.TransformDirection(Vector3.forward), out var hit, maxDistance))
{
Debug.DrawRay(camTrans.position, camTrans.TransformDirection(Vector3.forward) * hit.distance, Color.red);
Debug.Log("Did Hit");
var clone = Instantiate(objectToSpawn, hit.point, Quaternion.Euler(0, 180, 0));
update = false;
}
else
{
Debug.DrawRay(camTrans.position, camTrans.TransformDirection(Vector3.forward) * 1000, Color.white);
Debug.Log("Did not Hit");
}
}
}
After hitting raycast
Hello everyone and thanks in advance for your answers!
I am a beginner in unity, coding my second game after i finshed a couple of tutorials.
Since today, i noticed that suddenly all my "GameObjects" have a "UnityEngine." in front of them.
I have no idea how that happened, and it is also not just in one script, but all of them. Heres an example of it:
UnityEngine.GameObject item = (UnityEngine.GameObject)Instantiate(itemGOList[i], spawnTransform, spawnRotation);
This worked fine before without the "UnityEngine.", but now it only works when its written this way.
Do you know how this could have happened and how to revert it?
This is one of the scripts:
using UnityEngine;
using UnityEngine.EventSystems;

The problem was that i had a script called "GameObject" in my Unity Project.
I was also able to rename all "UnityEngine.GameObject" to "Gameobject" by using the Quick Action in Visual Studio.
Hey I am making a top down game in unity. The problem I ma having is making npc players change the way they are facing while following the player. So if the player turns left the npc follows them but doesn't turn to face the direction the npc is going. I can get the npc to look like its walking just not change the direction it is looking. This is a 2d top down game please any help will be nice. here is my npc code.
using UnityEngine;
using System.Collections;
public class SlimeController : MonoBehaviour
{
public Transform Character; // Target Object to follow
public float speed = 0.1F; // Enemy speed
public float maxDist = 10.0f;
public float attackdistance = 3;
public float farenough;
private Vector3 directionOfCharacter;
private bool challenged = false;// If the enemy is Challenged to follow by the player
public Transform StartMarker;
private Vector3 goback;
public Transform EndMarker;
public Rigidbody2D rb;
Animator anim;
float oldx;
bool left;
bool right;
private void Start()
{
rb = GetComponent<Rigidbody2D>();
anim= GetComponent<Animator>();
oldx = transform.position.x;
}
void Update()
{
anim.SetBool("left", false);
anim.SetBool("right", false);
var distanceFromPlayer = Vector3.Distance(Character.position, transform.position);
if(oldx>transform.position.x)
{
left = false;
right = true;
}
if(oldx<transform.position.x)
{
left = true;
right = false;
}
if (oldx == transform.position.x)
{
left = false;
right = false;
}
if (challenged)
{
directionOfCharacter = Character.transform.position - transform.position;
directionOfCharacter = directionOfCharacter.normalized; // Get Direction to Move Towardsss
transform.Translate(directionOfCharacter * speed, Space.World);
enabled = true;
if (distanceFromPlayer < attackdistance)
{
attack();
}
if (distanceFromPlayer > attackdistance)
{
speed = 0.03f;
}
}
if (!challenged)
{
goback = StartMarker.transform.position - transform.position;
goback = goback.normalized;
transform.Translate(goback * speed, Space.World);
}
}
// Will be triggered as soon as player would touch the Enemy Object
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.name == ("Player"))
{
challenged = true;
}
}
private void OnTriggerExit2D(Collider2D other)
{
if (other.gameObject.name == ("Player"))
{
speed = 0.03f;
challenged = false;
}
}
void attack()
{
speed = 0;
transform.Translate(directionOfCharacter * speed, Space.World);
}
}
This is because you are just moving the object towards your target. But to have it look at your target you need to also rotate it in the direction of your target.
The Transform Component has a function called LookAt. You supply it with your Target and the Axis your object should rotate around. So in your case:
this.transform.LookAt(Character, Vector3.up);
See here for more info on LookAt.
I am messing around in Unity and wanted to make a mechanic where a box would touch another object and then that object would follow the Player.
I have Cube set up like this:
And a Sphere with a Box Collider with same options.
My Player script is thus:
public class Player : MonoBehaviour {
public float speed = 0.0f;
public float moveX = 0.0f;
public float moveY = 0.0f;
public GameObject player;
public GameObject obj;
//public float force = 0.0f;
private bool collided = false;
// Use this for initialization
void Start () {
player = GameObject.FindWithTag ("Player");
}
// Update is called once per frame
void FixedUpdate () {
moveX = Input.GetAxis ("Horizontal");
moveY = Input.GetAxis ("Vertical");
player.GetComponent<Rigidbody> ().velocity = new Vector2 (moveX * speed, moveY * speed);
}
void OnCollisionEnter (Collision col) {
if (col.gameObject == obj) {
collided = true;
}
}
void OnCollisionExit (Collision col) {
if (col.gameObject == obj) {
collided = false;
}
}
void Update () {
if(collided) {
obj.transform.position = (player.transform.position - obj.transform.position)*speed;
}
}
}
What have I yet to do? Hoping someone can nudge me in the right direction.
I will provide you two scripts.
1st Script is FollowTarget. This will follow your target forcely.
2nd Script is SmoothFollow which will follow your target in a smooth movement.
FollowTarget.cs
using System;
using UnityEngine;
public class FollowTarget : MonoBehaviour
{
public Transform target;
public Vector3 offset = new Vector3(0f, 7.5f, 0f);
private void LateUpdate()
{
transform.position = target.position + offset;
}
}
SmoothFollow.cs
using UnityEngine;
public class SmoothFollow : MonoBehaviour
{
// The target we are following
[SerializeField]
private Transform target;
// The distance in the x-z plane to the target
[SerializeField]
private float distance = 10.0f;
// the height we want the camera to be above the target
[SerializeField]
private float height = 5.0f;
[SerializeField]
private float rotationDamping;
[SerializeField]
private float heightDamping;
// Use this for initialization
void Start() { }
// Update is called once per frame
void LateUpdate()
{
// Early out if we don't have a target
if (!target)
return;
// Calculate the current rotation angles
var wantedRotationAngle = target.eulerAngles.y;
var wantedHeight = target.position.y + height;
var currentRotationAngle = transform.eulerAngles.y;
var currentHeight = transform.position.y;
// Damp the rotation around the y-axis
currentRotationAngle = Mathf.LerpAngle(currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
// Damp the height
currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);
// Convert the angle into a rotation
var currentRotation = Quaternion.Euler(0, currentRotationAngle, 0);
// Set the position of the camera on the x-z plane to:
// distance meters behind the target
transform.position = target.position;
transform.position -= currentRotation * Vector3.forward * distance;
// Set the height of the camera
transform.position = new Vector3(transform.position.x ,currentHeight , transform.position.z);
// Always look at the target
transform.LookAt(target);
}
}
Just choose one of them and then attach it to the gameObject. Like another box that is suppose to follow.
Remove your Update() function in your script as you don't need it anymore.
Also Remove your OnCollisionExit()
void OnCollisionEnter (Collision col) {
if (col.gameObject == obj) {
// If you choose to use SmoothFollow Uncomment this.
//col.GetComponent<SmoothFollow>().target = this.transform;
// If you choose to use FollowTarget Uncomment this
//col.GetComponent<FollowTarget>().target = this.transform;
}
}
