How to change a Player direction by colliding a Game Object
Hello Everyone , im not used to ask help but i'm getting stuck in my code so ...
The code below is applied to a Game Object "Player" : When i hit "Play" the Player is moving up until its collides with a "Reflector" ,( a gameobject with a collider2d component) then its change direction depending of which kind of "Reflector" its encounters ...
public class playerMove : MonoBehaviour
{
Vector3 myVector;
Rigidbody2D m_Rigidbody;
[SerializeField] float m_Speed = 2.0f;
void Start()
{
myVector = new Vector3(0.0f, 1.0f * m_Speed, 0.0f);
m_Rigidbody = GetComponent<Rigidbody2D>();
}
void OnTriggerEnter2D(Collider2D col)
{
if (col.gameObject.tag == "ReflectorLeft")
{
myVector = new Vector3(-1.0f * m_Speed, 0.0f, 0.0f); // if Player touch reflector its turns "Left"
}
if (col.gameObject.tag == "ReflectorRight")
{
myVector = new Vector3(1.0f * m_Speed, 0.0f, 0.0f);
}
}
Its working well , but i would like to apply the change of direction directly from a script stored in each kind of reflector and not in the PlayerMove only .
public class ReflectorLeft : MonoBehaviour
{
public GameObject selectPlayer; // Store Player prefab
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.tag == "Player")
{
selectPlayer. ** change direction to left**
}
}
What should i add in my ReflectorLeft.cs ? (sorry for my english) Thanks by advance Gwendoline

I would create a generic "Reflector" class and use an enum so you have a dropdown on each reflector to choose the type. Like this:
public class Reflector : MonoBehaviour
{
public enum ReflectorType
{
Left,
Right
}
public ReflectorType reflectorType; //Choose reflector type
public GameObject selectPlayer; // Store Player prefab
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.tag == "Player")
{
switch (reflectorType)
{
case ReflectorType.Left:
selectPlayer.SendMessage("ReflectTowards", new Vector3(-1.0f, 0.0f, 0.0f));
// In the ReflectTowards method, multiply the whole Vector3 by the m_Speed
break;
case ReflectorType.Right:
selectPlayer.SendMessage("ReflectTowards", new Vector3(1.0f, 0.0f, 0.0f));
// In the ReflectTowards method, multiply the whole Vector3 by the m_Speed
break;
}
}
}
}
On the player, you would handle the method like this:
public void ReflectTowards(Vector3 newVector)
{
myVector = newVector * m_Speed;
}
