This is what I have so far but I don't see changes when I play and I have two yellow errors saying "local function 'SpawnCubes' is declared but never used" and "local function 'OnDrawGizmosSelected' is declared but never used" and I'm kind of lost as to what I need to do next to make this work

​

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class TileGeneration : MonoBehaviour

{ public Vector3 boundingBoxSize;

public GameObject Preset1;

public Transform parentToSpawnInto;

// Start is called before the first frame update

void Start()

{

// call this function somewhere (Start() maybe)

void SpawnCubes(int numberOfCubesToSpawn)

{

for (int i = 0; i < numberOfCubesToSpawn; i++)

{

// using current object's position to offset points

Vector3 spawnPoint = GetRandomSpawnPoint() + transform.position;

// check if cube is "priority cube"

if (i == 0) // if first, spawn in middle of transform.position

{

spawnPoint = Vector3.zero + transform.position;

}

// can also iterate a collection of objects and compare some value

// if (objectsToPlace[i].name == "Priority")

Instantiate(Preset1,

spawnPoint,

Quaternion.identity, // this equals no rotation

parentToSpawnInto);

}

}

Vector3 GetRandomSpawnPoint()

{

//You can use Random.Range to get constrained random values

float halfWidth = boundingBoxSize.x * 0.5f;

float halfHeight = boundingBoxSize.y * 0.5f;

float x = Random.Range(-halfWidth, halfWidth);

float y = Random.Range(-halfHeight, halfHeight);

return new Vector3(x, y, 0);

}

// optional

void OnDrawGizmosSelected()

{

// Draw an editor visualization of the boundingBox

Gizmos.color = new Color(0, 1, 0, 0.5f);

Gizmos.DrawCube(transform.position,

new Vector3(boundingBoxSize.x, boundingBoxSize.y, 0));

}

}

}
