Destroy one prefab clone of set of clones.
To be more specific, is there a way to destroy a certain clone from a list of clones? My problem is that I have 5 HousePrefab(Clone)s in my scene, I placed them using raycast, say I only wanted 4 and I built too many. Using this code deletes the first once built which is not what I want, I'd like to delete the one my mouse is over.
if (Input.GetButtonDown ("Fire1") && collider.Raycast (ray, out hitInfo, Mathf.Infinity) && KeepingScore1.Selected == 4) {
Destroy(GameObject.Find("House(Clone)"));
}
// KeepingScore.Selected == 4 is a reference to my 'remove' button being active.
I'm a bit stuck because I'm not sure if I can use Raycast to solve my issue. Or whether I need to make an array of gameObjects or if attaching a script to the HousePrefab would do it. Any advice on the way forward would be greatly helpful.
public Transform HousePreFab = (Transform)Resources.Load("House", typeof(Transform));
public class Tile : MonoBehaviour {
void Update () {
ClicktoChangeWeight ();
}
void ClicktoChangeWeight(){
int a = Weight;
Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
RaycastHit hitInfo;
if (collider.Raycast (ray, out hitInfo, Mathf.Infinity)) {
if (Physics.Raycast (ray, out hitInfo)){
if (Input.GetButtonDown("Fire1") && hitInfo.transform.gameObject.tag == "House" && KeepingScore1.Selected == 4) {
//Destroy(GameObject.Find("House(Clone)")); // Destroys House(clone) at the top of the list.
//Destroy(GameObject.FindWithTag ("House")); // Destroys House(clone) at the top of the list.
Debug.Log("House Hit"); // Works fine
}
}
}
}}
So this is my code. Sorry for the syntax. I have tried verious versions of Destroy(); as shown with the comments. Each time the House(Clone) that gets destroyed is the first one created. I am trying to identify the House(Clone) prefab that is at the cursor position.
Thanks a lot! That works! $$anonymous$$uch gratitude to you.
It seems what you're saying is that, if they have placed 4 houses down, then when they place the fifth, destroy that fifth. The solution to this: Before the code that involves placing the house, have an if statement that checks the number of houses and only executes if there are only <4 houses; i.e.
if(houses <4)
{
if(Mouse1)
{
if(raycast)
{
}
}
}
The Amount of clones isn't the issue here I'm afraid. I already have code that stops a prefab from being placed in the same location using if(houses <4) type of code.
Previously I used GameObject HousePrefab; but this time I am using Transform HousePrefab. Using raycast this is the only difference I can see in my code, I may have to just use GameObject when I initialize.
