Transform an object in other

=======

Hi, I’m creating a game, and some of the mechanics I want, is a power, a staff turns into a snake, how can I do this in C #? The snake must have animations, AI.

trigger it somehow and instantiate a prefab. like if the player gets close to the staff or if the player has a certain amount of points or whatever condition is required to turn the staff into a snake. The snake will be a prefab with animation and AI scripts on it. When the condition is met to make the staff change, destroy it and instantiate the snake. The code below is if the player gets close to the staff. The staff needs a trigger collider and this script.

using UnityEngine;
using System.Collections;

public class staffChange : MonoBehaviour {
public GameObject  snake;//this is where you drag the snake prefab

void OnTriggerEnter(Collider other) {
			if(other.tag == "player")
			{

Instantiate(snake, transform.position , transform.rotation);
Destroy(gameObject);
}
}
}

for a score requirement of 50 points:

 using UnityEngine;
 using System.Collections;
 
 public class staffChange : MonoBehaviour {
 public GameObject  snake;//this is where you drag the snake prefab
public GameObject PlayerScore;//this is where you drag the  gameobject with scoring script
 MonoBehaviour score;// this is the value in the scoring script of the players score
void start()
score =  PlayerScore.GetComponent<scoreScript>();
 }
if( scoreScript.score = 50)
{
 
 Instantiate(snake, transform.position , transform.rotation);
 Destroy(gameObject);
}
}
}

Just create a snake prefab with all the functions you need. Then create a script and attach it to the staff that will replace it with this new snake prefab. Something like this:

using UnityEngine;

public class StaffSwappingScript : MonoBehaviour
{
    public GameObject swapObject; // drag snake prefab onto this from the editor.

    // call this when you want to switch to the "swapObject" object.
    public void Swap()
    {
        // spawn replacement object with same position and rotation.
        var replacement = Instantiate(swapObject, transform.position, transform.rotation);

        // might want to also make sure it has the same parent?
        replacement.transform.parent = transform.parent;

        // destroy the old object we're replacing.
        Destroy(gameObject);
    }
}

This script could be attached to the staff itself for onetime switching or the player and expanded to allow for switching back and forth.

Note: “transform” and “gameObject” are helper functions to easily access the GameObject and Transform the script is attached to. If you attach the script to something else this code will need to be modified to make it work.
