I'm making a little game in Unity, with Stickybombs. I made it so that when you press Right Click, the stickybomb blows up, destroys itself, and instantiates a particle effect for explosions. Here is the following code:
void Update () {
if(Input.GetButtonDown("Fire2")) {
GetComponent<Rigidbody>().isKinematic = false;
GetComponent<Rigidbody>().AddExplosionForce(explosionForce, transform.position, explosionRadius, 3.0f);
Destroy(gameObject);
Instantiate (Explosion, transform.position, new Quaternion(0, 0, 0, 0));
}
}
However, the line GetComponent().AddExplosionForce(explosionForce, transform.position, explosionRadius, 3.0f); doesn't do anything. Am I doing something wrong?
Here is the variables. Thanks in advance :D
public GameObject Explosion;
private float explosionForce = 300;
private float explosionRadius = 15f;
My previous comment, converted into an answer:
Don't know if it can help, but you destroy the object as soon as AddExplosionForce is invoked. This way, you don't have the time to simulate the explosion effect, because the object is immediately destroied. Have you tried by removing the Destroy() call and see what happpens?
Side note: I suggest to call the Destroy() function at the end, and using a delay, as an example.

So I am trying to make a multiplayer game with abilities sort of like Overwatch/Paladins. All in all, one ability should be a sort of projectile that moves across the ground and allows that player to teleport to its position at any time while it is alive. I can't find the solution to teleporting only the player that shot it since thus far in my tests, when one player activated their ability, all players would teleport. How can I solve this?
My code:
void Update()
{
if (Input.GetKeyDown(KeyCode.E))
GetComponent<playerController>().heldAbility = "gateCrash";
if (GetComponent<playerController>().heldAbility == "gateCrash")
holding = true;
else
holding = false;
if (holding && Input.GetMouseButtonDown(0))
PhotonNetwork.Instantiate(Path.Combine("PhotonPrefabs", "GateCrashModel"), spawnPos, transform.rotation, 0);
}
This code is attached to the projectile:
public float speed = 10;
PhotonView pv;
private void Awake()
{
pv = transform.GetComponent<PhotonView>();
}
private void FixedUpdate()
{
transform.Translate(transform.forward * speed * Time.fixedDeltaTime);
}
I guess that I should make have something as instatntiation parameter but idk what.
A simple approach would be to add a shotOwner property to each of your projectiles. Every time a projectile is fired, update shotOwner to point to the player object that fired the shot. (This will also let you implement "Player_X killed Player_Y" functionality, among other things.)
When I retrieve an object from a list of created objects and reactivate it, it destroys itself, but only if I have force applied to start it moving. If I never apply force, everything works as intended and I can keep activating the object over and over.
I've tried putting a debug.log in the OnCollision and it isn't colliding with anything.
As said above, if I never initiate speed, the rest works fine.
When speed is applied, the first projectile works, the second destroys itself.
I've tried manually activating them instead of by code. Same result.
Exception: If I manually activate/deactivate objects myself through the inspector, they work if I only have 1 shot in the pool.
The one shot rule doesn't work if I do it through code. It breaks even if I only have one shot.
All the code worked when I wasn't using pooling.
Spawn code:
void CreateBullet(int GunID)
{
GameObject ShotFired = Guns[GunID].GetComponent<Weapon>().FireWeapon();
if (ShotFired == null)
{
ShotFired = Instantiate(Guns[GunID].GetComponent<Weapon>().Projectile,Guns[GunID].gameObject.transform);
Physics.IgnoreCollision(ShotFired.GetComponent<SphereCollider>(), Guns[GunID].GetComponentInParent<CapsuleCollider>());
Guns[GunID].GetComponent<Weapon>().AmmoPool.Add(ShotFired);
}
ShotFired.transform.position = Guns[GunID].transform.position;
ShotFired.transform.rotation = Guns[GunID].transform.rotation;
ShotFired.SetActive(true);
}
Projectile Code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Mirror;
public class Projectile : NetworkBehaviour
{
public float Speed;
public float LifeTime;
public float DamagePower;
public GameObject ExplosionFX;
// Start is called before the first frame update
void Start()
{
GetComponent<Rigidbody>().AddRelativeForce(Vector3.up * Speed, ForceMode.VelocityChange);
StartCoroutine(DeactivateSelf(5.0f));
}
private void OnDestroy()
{
Debug.Log("WHY!");
}
IEnumerator DeactivateSelf(float Sec)
{
yield return new WaitForSeconds(Sec);
Explode();
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.GetComponentInChildren<Vehicle>())
{
collision.gameObject.GetComponentInChildren<Vehicle>().CmdTakeDamage(DamagePower);
}
Explode();
}
void Explode()
{
GameObject ExplosionEvent = Instantiate(ExplosionFX, this.transform.position, Quaternion.identity);
NetworkServer.Spawn(ExplosionEvent);
GetComponent<Rigidbody>().AddRelativeForce(Vector3.zero);
gameObject.SetActive(false);
}
}
Any thoughts welcome. Thanks in advance!
In case anyone else stumbles across this, here's what happened and why assigning a movement speed to the object was what caused the issue.
My projectiles had a 'trailrenderer' on them.
By default 'Autodestruct' is true.
Autodestruct does not destruct the trail, but the game object when the trail disappears. So if you disable anything that had a trail, and activated it through movement, when the object stops moving (say to reposition in an object pool) it will destroy the parent object.
If the object never moves, it never generates a trail, and never needs to be destroyed.
To fix, just uncheck autodestruct.

so recently my friends and I are trying to make a game for fun. Currently, I hit a wall and not sure how to do this. I am trying to create a simple base script where I have the character move and attack with right click. If it hits the ground, it will move there and and if in range of a target, it will send a projectile. So the game is creating the projectile but its not actually moving. Can anyone tell me what I should probably do. At first, I thought to just make it all one script but now I am thinking it be best to make another script for the projectile.
void Update()
{
if (Input.GetMouseButtonDown(1))
{
RaycastHit hit;
if(Physics.Raycast (Camera.main.ScreenPointToRay(Input.mousePosition), out hit) && hit.transform.tag == "Minion")
{
if(Vector3.Distance(this.transform.position, hit.point) <= atkRange)
{
GameObject proj = Instantiate(bullet) as GameObject;
proj.transform.position = Vector3.MoveTowards(this.transform.position, target, atkSpd);
}
}
else if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hit, speed))
{
agent.destination = hit.point;
}
}
}
So this is what I originally had. I am pretty sure I did something wrong here. Also I am not sure if I should have another script for the projectile itself or if it is not necessary. Thank you for any help or tips on what to do.
For starters, I'd advize using a Rigidbody component and letting physics handle movement but if you'd like to use Vector3.MoveTowards, it'll be a bit of work:
Vector3.MoveTowards is something that needs to be called every frame. I'm guessing bullet is your prefab so you'll want to make a new script for the movement and place it on that prefab:
public class MoveToTarget : MonoBehaviour
{
private float _speed;
private Vector3 _target;
public void StartMovingTowards(Vector3 target, float speed)
{
_target = target;
_speed = speed;
}
public void FixedUpdate()
{
// Speed will be 0 before StartMovingTowards is called so this will do nothing
transform.position = Vector3.MoveTowards(transform.postion, _target, _speed);
}
}
After you've attached this to your prefab, make sure you grab a reference and get it started when you instantiate a copy of your prefab:
GameObject proj = Instantiate(bullet) as GameObject;
var movement = proj.GetComponent<MoveToTarget>();
movement.StartMovingTowards(target, atkSpd);
If you instead go the physics route, add a Rigidbody component to your bullet prefab, and get a reference to that instead of making the MoveToTarget script:
GameObject proj = Instantiate(bullet) as GameObject;
var body = proj.GetComponent<Rigidbody>();
Then you can just apply a force and let physics take over:
body.AddForce(target - transform.position, ForceMode.Impulse);
Don't set the position like you currently are
proj.transform.position = Vector3.MoveTowards(this.transform.position, target, atkSpd);
Instead, add either a characterController or a rigidbody and use rb.addVelocity.
I have coded up a simple raycast script that is attached to the hand of an Oculus Motion Controller. The idea is - the controller acts like a vacuum, it sucks up the prefabbed objects called "Eosinophil2(Clone)".
On a few tests outside of the motion controller this works.
The trouble I am experiencing is when I place the Raycast script into the motion controller. It only appear to work as anticipated when I am beside the Guardian Border.
I have turned on and off the border to see if that solved anything but it did not.
I've checked that the line raycast line goes in the right direction - and it is.
Any ideas?
void FixedUpdate()
{
// OVRInput.SetControllerVibration(.3f, 0.3f, OVRInput.Controller.RTouch);
var up = transform.TransformDirection(Vector3.forward);
//note the use of var as the type. This is because in c# you
// can have lamda functions which open up the use of untyped variables
//these variables can only live INSIDE a function.
RaycastHit hit;
Debug.DrawRay(transform.position, up * 20, Color.green,1);
if (Physics.Raycast(transform.position, up, out hit, 20))
{
if (hit.collider.gameObject.name == "Eosinophil2(Clone)")
{
OVRInput.SetControllerVibration(.3f, 0.3f, OVRInput.Controller.RTouch);
hit.collider.gameObject.transform.position = Vector3.MoveTowards(hit.collider.gameObject.transform.position, transform.position, 20 * Time.deltaTime);
}
else
{
//OVRInput.SetControllerVibration(0, 0, OVRInput.Controller.RTouch);
}
}
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject.transform.name == "Eosinophil2(Clone)")
{
this.gameObject.GetComponent<AudioSource>().Play(0);
Debug.Log("works");
Destroy(other.gameObject);
Debug.Log("HIT ONE!");
hitRate++;
}
}`enter code here`
Moral of the story - build your scene from scratch.
Use the OVRCameraRig prefab in said build scene.
Using prebuilt scenes from Oculus can be detrimental to ones health, time and code.
I hope this helps someone someday.
I am trying to make a 2D platformer but my player is not firing on both side I don't know what is wrong with my script.
using UnityEngine;
using System.Collections;
public class Bullet : MonoBehaviour
{
public float bulletSpeed;
public GameObject bullet;
public Transform bulletX;
GameObject clone;
void Update ()
{
if (Input.GetKeyUp ("space"))
{
clone = Instantiate(bullet,new Vector3(bulletX.position.x,bulletX.position.y+0.1f,0f),Quaternion.identity) as GameObject;
if (GameObject.Find ("Player").GetComponent<Player> ().left == true)
bulletSpeed = -30f;
else
bulletSpeed = 30f;
}
bullet.rigidbody2D.velocity = new Vector2(bulletSpeed * 0.5f, 0f);
Destroy (clone, 1f);
}
}
I tried to increase velocity inside the if condition but bullet was moving faster than I needed.
I think your question was very hard to understand what you want to accomplish, but I can see some errors in your code that will render the "clone" you are creating, useless.
The update loop is continuously executing, and you have placed the destroy outside your "Press space" code block. Unity tries to destroy it every frame. Place it inside the space.
I feel it should look more like this:
if (Input.GetKeyUp ("space"))
{
clone = Instantiate(bullet,new Vector3(bulletX.position.x,bulletX.position.y+0.1f,0f),Quaternion.identity) as GameObject;
if (GameObject.Find ("Player").GetComponent<Player> ().left == true)
bulletSpeed = -30f;
else
bulletSpeed = 30f;
bullet.rigidbody2D.velocity = new Vector2(bulletSpeed * 0.5f, 0f);
Destroy (clone, 1f);
}
This might not answer your question, but could you specify more what behaviour you are after? And what object is this script running on? (It is called Bullet with a field referance to another bullet ?)
Debug.Log your bulletSpeed * 0.5f
If I am correct. Even if your Player is Looking at the other way. It is returning
an ABS number meaning (bulletSpeed = -30f & 0.f is != -44954 something but == 44954).
Alternatively you can use AddForce instead of Velocity. It is easier to control.
QUESTION. Why not use Instantiate Vector2?
