How to get position of instantiated object before it is destroyed
So I have a line that shoots out from the player and rotates around them when the mouse button is held down. When I let up on the mouse the line disappears. I have a gameobject attached to the end of the line furthest from my player and I would like the player to teleport/move towards it when the line is gone. However, I cannot seem to figure out how to send the coordinates of the gameobject to another script so that I can do that. Does anyone know how to do this?
Sounds like some sort of grapple system? Interesting.
If the object is a prefab that is instantiated and you have a trigger to detect collision:
//Make a variable on your player called last hit.
public Vector3 lastHit;
//Then from the game object script:
GameObject.FindObjectOfType<YourPlayerMonoBehaviorClass>().lastHit = transform.position;
This of course has a lot of room for error, and relies on collision detection from the GameObject.
A workaround here would be to instead just have the object always a child of the player, and set its script component as a variable and grab last hit from that script, and then SetActive when you want it.
public hitGameObject;
//In your player update function:
if (Input.GetKey(KeyCode.Space)){
hitGameObject.transform.SetActive(true);
if (hitGameObject.lastHit != null){
//move player twords last hit.
}
}else{
hitGameObject.lastHit = null;
hitGameObject.transform.SetActive(false);
}
//On your hitGameobject:
public class hitGameObject{
public Vector3 lastHit;
void OnTriggerStay(other collider){
lastHit = transform.position;
}
}
Alternatively, if it is a first person game, perhaps a raycast would suit you better?
RaycastHit hit;
float distance = 50.0f;
// Does the ray intersect any objects excluding the player layer
if (Physics.Raycast(transform.position, transform.forward, out hit, distance))
{
Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * hit.distance, Color.yellow);
Vector3 gameobjectPosition = hit.point;
}
Thank you so much! Unfortunately, I was not able to make the object a child as is does a weird flip whenever the player turns, so I just made it follow the player and set it as a separate gameobject. After working around a bit I ended up using your idea of activating/deactivating the scripts when the trigger was activated and just used GetComponent to find the position of the end target. Thank you for your help!
