transform.position reads 0 but the actual position is different
Hi,
I'm trying to read the position of a gameobject where a script placed on, but the reading always stays (0.0,0.0,0.0), While the actual position of the object is different
This is the Pattern script that is reading the position
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public struct ShotVariables
{
public float Speed;
public int Direction;
}
public class PatternPoint
{
public List<ShotVariables> Shots = new List<ShotVariables>();
public int Time;
public PatternPoint(int time)
{
Time = time;
}
public void NewShot(int direction, float speed)
{
ShotVariables _shot_variables = new ShotVariables();
_shot_variables.Direction = direction;
_shot_variables.Speed = speed;
Shots.Add(_shot_variables);
}
}
public class Pattern : MonoBehaviour
{
[SerializeField]
public List<PatternPoint> PatternPoints = new List<PatternPoint>();
public GameObject Shot;
public Vector3 Position;
private int ShotIndex;
private int Counter;
public void Wake()
{
ShotIndex = 0;
Counter = 0;
Debug.Log(this.transform.position);
InvokeRepeating("Shoot", 1.0f, 0.1f);
}
public PatternPoint NewPatternPoint(int Time)
{
PatternPoint _patternPoint = new PatternPoint(Time);
return _patternPoint;
}
private void Shoot()
{
Position = this.transform.position;
Debug.Log(Position);
if (ShotIndex < PatternPoints.Count)
{
if (PatternPoints[ShotIndex].Time == Counter)
{
for (int i = 0; i < PatternPoints[ShotIndex].Shots.Count; i++)
{
Debug.Log(Position);
GameObject _Shot = Instantiate(Shot, Position, Quaternion.identity) as GameObject;
Shot _shot_script = _Shot.GetComponent<Shot>();
_shot_script.SetDirection(PatternPoints[ShotIndex].Shots[i].Direction);
_shot_script.Speed = PatternPoints[ShotIndex].Shots[i].Speed;
}
ShotIndex++;
}
Counter++;
}
else
{
CancelInvoke();
}
}
}
The Debug.Log statement on line 69 is reading (0.0,0.0,0.0), which should be (2.0, 1.0, 0.0) which is the actual position in the inspector
This object is instantiated in another script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TimingPoint
{
public int Time;
public GameObject Enemy;
public Enemy enemyScript;
public float StartX;
public Vector2 StallMarker;
public float ApproachSpeed;
public TimingPoint(int newTime, GameObject newEnemy, float startX, Vector2 endMarker, float approachSpeed)
{
StartX = startX;
StallMarker = endMarker;
ApproachSpeed = approachSpeed;
Time = newTime;
Enemy = newEnemy;
}
}
public class MapPlay : MonoBehaviour
{
public List<TimingPoint> TimingPoints = new List<TimingPoint>();
public GameObject Enemy;
public int MapLength;
private int enemyIndex;
private int Counter;
private void Awake ()
{
enemyIndex = 0;
Counter = 0;
TimingPoint TP1 = new TimingPoint(10, Enemy, 2f, new Vector2(2f, 1f), 7f);
Pattern P1 = TP1.Enemy.GetComponent<Pattern>();
PatternPoint PP1 = P1.NewPatternPoint(1);
PP1.NewShot(180, 0.01f);
PP1.NewShot(170, 0.01f);
PP1.NewShot(190, 0.01f);
P1.PatternPoints.Add(PP1);
TimingPoints.Add(TP1);
InvokeRepeating("PlaceEnemies", 3.0f, 0.1f);
}
private void PlaceEnemies()
{
if ((enemyIndex <= TimingPoints.Count - 1))
{
if (TimingPoints[enemyIndex].Time == Counter)
{
GameObject _enemy = Instantiate(TimingPoints[enemyIndex].Enemy, transform.position, Quaternion.identity) as GameObject;
Enemy _enemy_script = _enemy.GetComponent<Enemy>();
_enemy_script.StartX = TimingPoints[enemyIndex].StartX;
_enemy_script.StallMarker = TimingPoints[enemyIndex].StallMarker;
_enemy_script.ApproachSpeed = TimingPoints[enemyIndex].ApproachSpeed;
TimingPoints[enemyIndex].Enemy.GetComponent<Pattern>().Wake();
enemyIndex++;
}
}
else
{
CancelInvoke();
}
Counter++;
}
}
The objects with a Pattern script attached are instantiated on line 61
The Wake() method in the Pattern script is called from the MapPlay class. But strange thing is, that if I try to read the position in an Update() method in the Pattern class, the readings are accurate.
I'm sure I am doing something wrong here which I can't seem to figure out.
I hope someone can see the obvious mistake I made. I know the code is not good, but I'm trying to make this work somehow.
If i'm not clear enough, i'm sorry, I tried my best to explain the issue.
Thank you in advance!
In MapPlay's PlaceEnemies() function you are calling the Wake() of the original prefab not the instantiated instance. You should replace this line
TimingPoints[enemyIndex].Enemy.GetComponent<Pattern>().Wake();
with
_enemy.GetComponent<Pattern>().Wake();
