I have been try for a while to stop the enemy rotate wen my player collide with it. I have insert a rigid body, and I have try to freeze position and also the freeze rotation but he keep doing the same, I can't find any were any info to learn about this problem.
I have google it a few times and could not find any thing, close to my problem.
This is the screenshot of the problem
https://imgur.com/fyryuqY
Also I have tried to set Angular drag to 0 but no success it keep doing the same.
It sounds like I am missing something, but I can't find any solution for it yet.
I have also tried to see all answers on unity forum but I can't find anywhere a solution or the way to learn about this problem.
I have edit to insert the enemy script
This is my enemy script
using UnityEngine;
using System.Collections;
public class target : MonoBehaviour {
public float health = 100f;
public Animator animx2;
public AudioSource audiovfx2;
public void TakeDamage (float amount)
{
health -= amount;
if (health <= 0f)
{
Die();
}
}
void Die()
{
animx2.SetBool("isdie",true);
audiovfx2.Play();
healthcontroller.score += 10;
health -= 10;
Destroy (gameObject, 1.5f);
}
void Update()
{
animx2 = GetComponent<Animator>();
GetComponent<AudioSource>().Play();
}
void OnTriggerEnter(Collider other) {
if (other.tag == "Player") {
Rigidbody rb = GetComponent<Rigidbody>();
rb.angularVelocity = Vector3.zero
//Stop Moving/Translating
//rbdy.velocity = Vector3.zero;
//Stop rotating
//rbdy.angularVelocity = Vector3.zero;
}
}
void OnTriggerExit(Collider other) {
if (other.tag == "Player") {
//here i want to return to normal
}
}
}
Thank you in advance
Did you try to nullify angularVelocity of the Rigidbody component, for example
rb.angularVelocity = Vector3.zero;

I am working on a small game for a school project, in which my player needs to attack enemies in a level. My plan is to have a collider that is enabled in an attached script, and then disabled when the attack is done. My current problem is that that the collider does not flip the way it is supposed to, it seems to flip directly on the overall x axis instead of flipping in the x axis related to the player. It is a child of the player so I am clueless as to why it is doing this. Any solutions or other approaches would be greatly appreciated. I will attach the current script that controls the collider below.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class VerticalSword : MonoBehaviour
{
//Variables use to active the colliders
Collider2D AttackColliderVertical;
//Variables for the location of the collider
Vector2 attackOffset;
private void Start()
{
AttackColliderVertical = GetComponent<Collider2D>();
attackOffset = transform.position;
AttackColliderVertical.enabled = false;
}
public void FixedUpdate()
{
attackOffset = transform.position;
}
public void AttackUp()
{
AttackColliderVertical.enabled = true;
if (attackOffset.y > 0)
{
transform.position = attackOffset;
}
else if (attackOffset.y < 0)
{
transform.position = new Vector2(attackOffset.x, (attackOffset.y * -1)); //I think the problem is somewhere in this if and else if statement
}
print("Attack up successful"); //Error checking (This works when run)
}
public void AttackDown()
{
AttackColliderVertical.enabled = true;
if (attackOffset.y > 0)
{
transform.position = new Vector2(attackOffset.x, (attackOffset.y * -1));
}
else if (attackOffset.y < 0)
{
transform.position = attackOffset; //I think the problem is somewhere in this if and else if statement
}
print("Attack down successful"); //Error checking (This works when run)
}
public void StopAttack()
{
AttackColliderVertical.enabled = false;
}
}
Use transform.localPosition, not transform.position (that's its world space position). You need to change it everywhere in this script; the Start() function and the two attack functions
so I been searching for hours on how to fix this problem but I couldn't find a solution so I wanted to ask here I have a walking particle VIDEO < ***as you can see in the video AFTER I walk 3 to 2 secs later the particles will
heres my code on my update I made it so it should check if we are moving to the right with the joystick then show it and if we are moving to the left with the joystick then it should show it as well but for some reason after that 2 to 3 secs the emittating wiill start[]
1
void Update()
{
if (joystick.Horizontal >= .2f)
{
hays.SetActive(true);
Instantiate(hays, particleposition.transform.position, hays.transform.rotation);
}
if (joystick.Horizontal <= -.2f)
{
hays.SetActive(true);
Instantiate(hays, particleposition.transform.position, hays.transform.rotation);
}
what I tried
I tried checking if its not doing the above code then it should just delete but it doesnt work at all it will still imitate I also tried checking the animation state but it still the same thing it wont stop imitating
if (joystick.Horizontal !>= .2f)
{
Destroy(gameObject, 1f);
}
if (joystick.Horizontal !<= -.2f)
{
Destroy(gameObject, 1f);
}
my full code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class partscript : MonoBehaviour
{
public Joystick joystick;
public GameObject hays;
public Rigidbody2D rb;
float horizontalMove = 0f;
public bool show = true;
public Animator animator2;
public Transform player;
public Transform particleposition;
// Start is called before the first frame update
void Start()
{
transform.position = particleposition.position;
animator2 = GetComponent<Animator>();
//Destroy(gameObject, 1f);
}
//destroy(hays);
// Update is called once per frame
void Update()
{
if (joystick.Horizontal >= .2f)
{
hays.SetActive(true);
Instantiate(hays, particleposition.transform.position, hays.transform.rotation);
}
if (joystick.Horizontal <= -.2f)
{
hays.SetActive(true);
Instantiate(hays, particleposition.transform.position, hays.transform.rotation);
}
if (joystick.Horizontal !>= .2f)
{
Destroy(gameObject, 1f);
}
if (joystick.Horizontal !<= -.2f)
{
Destroy(gameObject, 1f);
}
}
}
removed loop and changed the duration to 1 and it started to work
The problem is that I what to create an openable door. This door should open when the player enter the Box Collider which is connected to the door. But the problem is when the door begins to open and to rotate, Collider starts to rotate too which brings me a lot of problems with usind such an idea. I try to create EmptyObject with its Collider but I can't connect this Collider with script and OnTriggerEnter function itself. Maybe I don't understand something, who knows, I'm just a begginer. How knows how to help, please write an answer.
My code if somebody needs it:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class openDoor : MonoBehaviour {
public Vector3 Rotation_;
private int i;
public float speed;
bool opentheDoor;
bool closetheDoor;
// Use this for initialization
void Start () {
opentheDoor = false;
closetheDoor = false;
}
// Update is called once per frame
void Update () {
if (opentheDoor == true) {
this.transform.Rotate (Rotation_ * Time.deltaTime * speed);
i += 1;
if (i == 70) {
opentheDoor = false;
i = 0;
}
}
if (closetheDoor == true) {
this.transform.Rotate (-Rotation_ * Time.deltaTime * speed);
i += 1;
if (i == 70) {
closetheDoor = false;
i = 0;
}
}
}
void OnTriggerEnter (Collider other) {
if (other.gameObject.tag == "Player") { {
opentheDoor = true;
}
}
}
void OnTriggerExit (Collider other) {
if (other.gameObject.tag == "Player") {
closetheDoor = true;
}
}
}
This is how i would handle the scenerio
Take
DoorHandler.cs
public class DoorHandler : MonoBehaviour {
public Door door;
private void OnTriggerEnter(Collider other)
{
if (other.CompareTag("Player"))
{
door.OpenDoor();
}
}
}
This should be attached to Parent of the door.
Next Take
Door.cs
public class Door : MonoBehaviour {
public bool isOpened = false;
public void OpenDoor()
{
if (!isOpened)
{
isOpened = true;
Debug.Log("OPEN");
//OPEN DOOR CODE!
}
}
}
Attach this to the Door GameObject
NOTE
The hierarchy would be like DoorHandler->Door->DoorModel (where Door is just an empty gameobject pivot of the Door)
In DoorHandler GameObject attach BoxCollider and Check Mark IsTrigger.
Also Player SHOULD HAVE A RIGIDBODY (preferably Kinametic) and obviously a collider
So When Player enters the DoorHandler's Collider -> The DoorHandler's OnTriggerEnter will be triggered and finally Call the Door to OpenDoor()
Add another check in OnTriggerEnter that checks if the door is currently opening or not.
void OnTriggerEnter (Collider other) {
if (other.gameObject.tag == "Player" && !opentheDoor) {
opentheDoor = true;
}
}
attach the door to an empty object. put the trigger on the empty object. then make the ontrigger entry rotate the door, not the paent object, and the collider will remain in place.
Parent
-child(door)
-child(collider)
i'm new to unity and i'm trying to make an endless runner. When my player (a ball) hits one of the walls the game needs to go the scene: LostMenu. My problem is that the collision doesn't work. Nothing happens when they collide... Here are the inspectors on both the player and the walls: Walls http://prntscr.com/a2pgzm Player http://prntscr.com/a2ph66 .
The collision script on the walls:
using UnityEngine;
using System.Collections;
public class LostByWallCSR : MonoBehaviour
{
void OnCollisionEnter (Collision col)
{
if(col.gameObject.name == "Player")
{
Application.LoadLevel("LostMenu");
Debug.Log ("WORKS!");
}
}
}
The movement script on the player:
using UnityEngine;
using System.Collections;
public class CharacterControllerz : MonoBehaviour {
public float speed = 5f;
public float gravity = 20f;
private Vector3 moveDirections = new Vector3();
private Vector3 inputs = new Vector3();
void FixedUpdate()
{
CharacterController cc = GetComponent<CharacterController>();
if (cc.isGrounded)
{
if (Input.GetKey("left"))
inputs.z = 3;
else if (Input.GetKey("right"))
inputs.z = -3;
else
inputs.z = 0;
moveDirections = transform.TransformDirection(inputs.x, 0, inputs.z) * speed;
}
inputs.x = 5;
moveDirections.y = inputs.y - gravity;
cc.Move(moveDirections * Time.deltaTime);
}
}
Any idea on how to setup the collision properly? Attaching a rigibody is not helping it. Unless i'm missing something ofcourse.
Make sure both objects have a collider component.
You need to attach a rigidbody component to one of the objects.(if you don't attach rigid body it will not work)
your Sphere collider is Trigger , remove that or change your function to
public void OnTriggerEnter(Collider other)
{
}
You need to use OnControllerColliderHit method
private void OnControllerColliderHit(ControllerColliderHit hit)
{
if (hit.gameObject.CompareTag("Trap"))
{
Debug.Log("colisiono with trap");
playerDentro = true;
}
else
{
if (!hit.gameObject.CompareTag("Trap"))
{
Debug.Log("player salio de la trampa");
playerDentro = false;
}
}
}e
i have a turret,as a game object when a enemy enters it's collison box,the turret starts firing towards it,the logic is when the enemy exits the collider,it should stop its firing ,and other problem is that when again an enemy enters the collison box i.e the second enemy,it gives me an exception ,"MissingReferenceException :the object of type 'transform' has been destroyed but you are still trying to access it.Your script should eihter be check if it is null or you should not destroy it",but i am checking if the list in not null in my code.here is my code
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class TurretScript : MonoBehaviour {
public float shotInterval = 0.2f; // interval between shots
public GameObject bulletPrefab; // drag the bullet prefab here
public float bulletSpeed;
private float shootTime = 0.0f;
private List<Transform> targets;
private Transform selectedTarget;
private Transform myTransform;
private Transform bulletSpawn;
void Start(){
targets = new List<Transform>();
selectedTarget = null;
myTransform = transform;
bulletSpawn = transform.Find ("bulletSpawn"); // only works if bulletSpawn is a turret child!
}
void OnTriggerEnter2D(Collider2D other){
if (other.tag == "enemy"){ // only enemies are added to the target list!
targets.Add(other.transform);
}
}
void OnTriggerExit2D(Collider2D other){
if (other.tag == "enemy"){
targets.Remove(other.transform);
Debug.Log("gone out");
}
}
void TargetEnemy(){
if (selectedTarget == null){ // if target destroyed or not selected yet...
SortTargetsByDistance(); // select the closest one
if (targets.Count > 0) selectedTarget = targets[0];
}
}
void SortTargetsByDistance(){
targets.Sort(delegate(Transform t1, Transform t2){
return Vector3.Distance(t1.position, myTransform.position).CompareTo(Vector3.Distance(t2.position, myTransform.position));
});
}
void Update(){
TargetEnemy(); // update the selected target and look at it
if (selectedTarget)
{
// if there's any target in the range...
Vector3 dir = selectedTarget.position - transform.position;
float angle = Mathf.Atan2(dir.y,dir.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);// aim at it
if (Time.time >= shootTime){// if it's time to shoot...
// shoot in the target direction
Vector3 lookPos = new Vector3(bulletSpawn.position.x,bulletSpawn.position.y,0);
lookPos = lookPos - transform.position;
float ang = Mathf.Atan2(lookPos.y,lookPos.x)*Mathf.Rad2Deg;
GameObject b1 = Instantiate(bulletPrefab,new Vector3(transform.position.x,transform.position.y,5),transform.rotation)as GameObject;
b1.rigidbody2D.velocity = new Vector3(Mathf.Cos(ang*Mathf.Deg2Rad),Mathf.Sin(ang*Mathf.Deg2Rad),0)*bulletSpeed;
shootTime = Time.time + shotInterval; // set time for next shot
}
}
}
}
here is my enemy script
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class EnemyScript : MonoBehaviour {
public Transform target;
public float speed = 2f;
public int Health;
public float GetHealth()
{
return Health;
}
void Update ()
{
transform.position = Vector2.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
}
void TakeDamage(int damage){
Health -= damage;
if (Health <= 0)
Destroy(gameObject);
}
void OnTriggerEnter2D(Collider2D otherCollider)
{
PlayerControl shot = otherCollider.gameObject.GetComponent<PlayerControl>();
if (shot != null)
{
SpecialEffectsHelper.Instance.Explosion(transform.position);
Destroy(shot.gameObject);
}
}
}
you need to check if the selected target is the target leaving the collider. You remove the target from the targets list but the selectedTarget var is still populated.
For the null ref exception. Are you using Destroy() to kill the target? Destroy() doesn't cause an OnTriggerExit() or OnCollisionExit() event call, the object is just gone.
edit: you can get around the lack of a call by adding an OnDestroy() function to the dying object that sets it's position to something well outside the level/view of the player. This way the target leaves the collider and then disappears rather than just disappearing in place.
