Im missing something here, more eyes might help

so i made this code, from a tutorial, but it wont work

im getting these errors:
error CS0103: The name `explosionRadius' does not exist in the current context
error CS0103: The name `explosionForce' does not exist in the current context
error CS0103: The name `explosionRadius' does not exist in the current context
error CS0103: The name `explosionUpward' does not exist in the current context





using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Explosion : MonoBehaviour {
public float cubeSize = 0.2f;
public int cubesInRow = 5;
float cubesPivotDistance;
Vector3 cubesPivot;

// Use this for initialization
void Start () {
//calculate pivot distance
cubesPivotDistance = cubeSize * cubesInRow / 2;
//use this value to create pivot vector
cubesPivot = new Vector3(cubesPivotDistance, cubesPivotDistance, cubesPivotDistance);

}
// Update is called once per frame
void Update() { }

private void OnTriggerEnter(Collider other){
if (other.gameObject.name == "Wall")
{
explode();
}

}
public void explode()
{
//make object disapper
gameObject.SetActive(false);

//loop 3 times to create 5x5x5 pieces in x,y,z coordinates
for (int x = 0; x < cubesInRow; x++)
{ for (int y = 0; y < cubesInRow; y++)
{ for (int z = 0; z < cubesInRow; z++)
{
createPiece(x, y, z);
}
}

}

//get expolosion position
Vector3 explosionPos = transform.position;
//get colliders in that position and radius
Collider[] colliders = Physics.OverlapSphere(explosionPos, explosionRadius);
//add explosion force to all colliders in that overlap sphere
foreach (Collider hit in colliders)
{
//get rigidbody from collider object
Rigidbody rb = hit.GetComponent<Rigidbody>();
if (rb != null)
{
//add explosion force to this body with given parameters
rb.AddExplosionForce(explosionForce, transform.position, explosionRadius, explosionUpward);
}
}
}
void createPiece(int x, int y, int z) {
//create piece
GameObject piece;
piece = GameObject.CreatePrimitive(PrimitiveType.Cube);
//create piece position and scale
piece.transform.position = transform.position + new Vector3(cubeSize * x, cubeSize * y, cubeSize * z) - cubesPivot;
piece.transform.localScale = new Vector3(cubeSize, cubeSize, cubeSize);
//add rigidbody and set mass
piece.AddComponent<Rigidbody>();
piece.GetComponent<Rigidbody>().mass = cubeSize;

}

Your script is incomprehensible if you do not use code tags; it needs indentation.

 

Please put your code in proper brackets ([.code])

Well, you did not initialize any of these variables, thus the error.

 

Well ... The first thing you're missing is a descriptive title for your post.

The second thing you're missing is code tags to make your post readable.

That seems to be about it... You can go ahead and mark this as "SOLVED"

 

You need to takes those functions like e.g. explode() out of your main Update() function.

 

Copy this Code Because you just not writte float and,
Not you see on video because they are cut video on edited, this
is youtuber mistake
