Unity堆栈游戏c#

Question

I am trying to recreate the Stack game where you stack square slices on top of each other and get it higher and higher. What's supposed to happen is the when the screen is clicked the square piece should stop at its current position and then a new square piece should spawn on top of it. Like so:

Optimal Output

However, this is what the game is doing on my end.

Current Output

Current Output2

The square piece spawns and is placeable. However, the next square piece spawns on the same Y-axis as the previous piece instead of spawning on top of the previous piece. From there it overlaps the previous pieces. Heres the scripts that have been written so far. Does anyone have an idea of how to fix this? Specifically how to get the script to get the optimal output as pictured above?

CubeSpawner.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CubeSpawner : MonoBehaviour
{
    [SerializeField]     
    private MovingCube cubePrefab;

    public void SpawnCube()
    {
        var cube = Instantiate(cubePrefab);

        if (MovingCube.LastCube != null && MovingCube.LastCube.gameObject != GameObject.Find("Start"))
        {
        cube.transform.position = new Vector3(transform.position.x,
            MovingCube.LastCube.transform.position.y + cubePrefab.transform.localScale.y,
            transform.position.z);
        }
        else
        {
            cube.transform.position = transform.position;
        }
    }

    private void OnDrawGizmos()
    {
        Gizmos.color = Color.green;
        Gizmos.DrawWireCube(transform.position, cubePrefab.transform.localScale);
    }
}

GameManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GameManager : MonoBehaviour

{
    private void Update()
    {
        if (Input.GetButtonDown("Fire1")) //if play presses left-click, control, tap a screen etc
        {
            if (MovingCube.CurrentCube != null)
                MovingCube.CurrentCube.Stop();

            FindObjectOfType<CubeSpawner>().SpawnCube();
        }
    }
}

MovingCube.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MovingCube : MonoBehaviour
{
    public static MovingCube CurrentCube { get; private set; }
    public static MovingCube LastCube { get; private set; }

    [SerializeField] //allows variable to be adjustable during runtime
    private float MoveSpeed = 1f;

    private void OnEnable()
    {
        if (LastCube == null)
            LastCube = GameObject.Find("Start").GetComponent<MovingCube>(); 

        CurrentCube = this;
        GetComponent<Renderer>().material.color = GetComponentRandomColor();

        transform.localScale = new Vector3(LastCube.transform.localScale.x, transform.localScale.y, LastCube.transform.localScale.z);

    }

    private Color GetComponentRandomColor()
    {
        return new Color(UnityEngine.Random.Range(0, 1f), UnityEngine.Random.Range(0, 1f), UnityEngine.Random.Range(0, 1f));
    }

    internal void Stop()
    {
        MoveSpeed = 0;
        float hangover = transform.position.z - LastCube.transform.position.z;

        float direction = hangover > 0 ? 1f : -1f;
        SplitCubeOnZ(hangover, direction);
    }

    private void SplitCubeOnZ(float hangover, float direction)
    { 
        float newZSize = LastCube.transform.localScale.z - Mathf.Abs(hangover);
        float fallingBlockSize = transform.localScale.z - newZSize;

        float newZPosition = LastCube.transform.position.z + (hangover / 2);
        transform.localScale = new Vector3(transform.localScale.x, transform.localScale.y, newZSize);
        transform.position = new Vector3(transform.position.x, transform.position.y, newZPosition);

        float cubeEdge = transform.position.z + (newZSize / 2f * direction);
        float fallingBlockZPosition = cubeEdge + fallingBlockSize / 2f * direction;

        SpawnDropCube(fallingBlockZPosition, fallingBlockSize);
    }

    private void SpawnDropCube(float fallingBlockZPosition, float fallingBlockSize)
    {
        var cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
        cube.transform.localScale = new Vector3(transform.localScale.x, transform.localScale.y, fallingBlockSize);
        cube.transform.position = new Vector3(transform.position.x, transform.position.y, fallingBlockZPosition);

        cube.AddComponent<Rigidbody>();
        cube.GetComponent<Renderer>().material.color = GetComponent<Renderer>().material.color;
        Destroy(cube.gameObject, 1f);
    }

    private void Update()
    {
        transform.position += transform.forward * Time.deltaTime * MoveSpeed; //moves the square piece
    }
}

Answer 1

I don't see any code changes the last cube after stop, so you may add it.

internal void Stop()
{
    ...

    MovingCube.LastCube = MovingCube.CurrentCube;
}
