Object not instantiating at the correct location

BeefCutlets · Jan 26, 2017

Hello,

I have searched everywhere on this site looking for similar problems but couldn't find any. After a couple days of trying to tinker with it I am coming to you guys for help because I can't figure it out for the life of me.

The problem is that the bullet object for my character is instantiating at a random, set location away from the desired spot. See this picture -> http://imgur.com/a/B76KP

My original thought was that it was spawning at world coordinates instead of local, but I couldn't get that to work. Next I figured my prefab have a wonky alignment, but after setting all of my prefab coordinates it still doesn't work. Even hard coding in the coords still gave me the same result. This is also happening when I instantiate the enemy's bullets, but I figure if I can get one fixed I can fix the other too

Here is the relevant code for my player controller...

public class fredController : MonoBehaviour
{

public float runSpeed, walkSpeed, dodgeSpeed;

public float xMin, xMax, yMin, yMax;

private GameObject outer, inner;
public GameObject bullet;
private float fireRate = 0.1f;
private float nextFire = 0.0F;

private Collider2D colOuter, colInner;
private SpriteRenderer outerSprRend, innerSprRend;
public Transform firePos;

void Start()
{

runSpeed = 5.0f;
dodgeSpeed = 2.0f;

xMin = -5.8f;
xMax = 5.8f;
yMin = -5.12f;
yMax = 5.12f;

outer = GameObject.FindGameObjectWithTag("OuterCollider");
inner = GameObject.FindGameObjectWithTag("InnerCollider");

outerSprRend = outer.GetComponent<SpriteRenderer>();
innerSprRend = inner.GetComponent<SpriteRenderer>();

}
// Update is called once per frame
void FixedUpdate()
{
Bounds();
Movement();
ControlHitBox();
}

void Update()
{
Shoot();
}
void Shoot()
{
if (Input.GetKey(KeyCode.Space) && Time.time > nextFire)
{
nextFire = Time.time + fireRate;
Instantiate(bullet, firePos.transform.position, transform.rotation);
}
}
}

And here is code for my bullet object

using UnityEngine;
using System.Collections;

public class Bullets : MonoBehaviour
{

private float speed = 20.0f;

public float xMin, xMax, yMin, yMax;

// Use this for initialization
void Start()
{
Debug.Log("BULLET: My starting positions are " + "X: " + this.transform.position.x + "Y: " + transform.position.y + "Z: " + transform.position.z);
GetComponent<Rigidbody2D>().velocity = transform.up * speed;
yMax = 17.0f;
}

// Update is called once per frame
void Update()
{
if (GetComponent<Rigidbody2D>().position.y >= yMax)
{
Destroy(this.gameObject);
}
}
}

Note the comment which still always pops up with the proper coords despite spawning in a different location.

If anyone had some ideas I would be very appreciative

Thanks!

is the firePos child from moving player ?

and if you are using "public Transform firePos;" then you have allready transform reference, so instead "firePos.transform.position" you can just use "firePos.position". Use "firePos.transform.position" for GameObject like
"public GameObject firePos;"

Yes, firePos is the child of the player. I also switched to just firePos.position but I still get the same result

I am sure, the solution is easy, but I cannot see it

Is the bullet builded from many object and the renderer is little offset ? Try place the bullet prefab in the scene and change its position to zero, then check if it is at zero point (place something other at zero, the camera as example, then it should be in middle of the camera). Or something is wrong with z-position and rotation.

where do you define the position of firepos? I don't see it in your code...

That was it! I knew that the objects that made up the "bullet" objects had an offset, but I thought it was just so that they were spaced properly. Apparently not though! Thank you

And unfortunately still necroing posts because of it. Please, hit the like button if you wish to show your appreication, rather than simply necroing threads.

This isn't even a 2D specific post. I'll move it to the scripting forum.

Thanks.
