Space Adventure

I created this game where the player controls a spaceship to navigate through outer space. Points are collected for every planet collected, but the game is over when the player collides with an alien.

Spawn Manager Script:

using System.Collections;

using System.Collections.Generic;

using System.Numerics;

using UnityEngine;

public class spawnManager : MonoBehaviour

{

public GameObject[] enemies;

public GameObject[] stars;

//make private later

public float zSpawn = -0.9f;

public float xSpawnRange = 12.3f;

public float ylowSpawn = -3.8f;

public float yhighSpawn = 5.8f;

public float starSpawnTime = 3.0f;

public static float enemySpawnTime = 0.5f;

public static float startDelay = 1.0f;

// Start is called before the first frame update

public void Start()

{

InvokeRepeating("SpawnRandomEnemy", startDelay, enemySpawnTime);

InvokeRepeating("SpawnRandomStar", startDelay, enemySpawnTime);

}

// Update is called once per frame

void Update()

{

}

public void SpawnRandomEnemy()

{

float randomX = Random.Range(-xSpawnRange, xSpawnRange);

int randomIndex = Random.Range(0, enemies.Length);

UnityEngine.Vector3 spawnPos = new UnityEngine.Vector3(randomX, yhighSpawn, zSpawn);

Instantiate(enemies[randomIndex], spawnPos, enemies[randomIndex].gameObject.transform.rotation);

}

public void SpawnRandomStar()

{

float randomX = Random.Range(-xSpawnRange, xSpawnRange);

int randomIndex = Random.Range(0, stars.Length);

UnityEngine.Vector3 spawnPos = new UnityEngine.Vector3(randomX, yhighSpawn, zSpawn);

Instantiate(stars[randomIndex], spawnPos, stars[randomIndex].gameObject.transform.rotation);

}

}

Movement Scripts:

Move Left:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class moveLeft : MonoBehaviour

{

public float speed = 0.5f;

public float xDestroy = -12.0f;

// Start is called before the first frame update

void Start()

{

}

// Update is called once per frame

void Update()

{

//moves to the left

transform.Translate(Vector3.left * speed);

// destroys when out of bounds

if (transform.position.x < xDestroy)

{

Destroy(gameObject);

}

}

}

Move Right:

using System.Collections;

using System.Collections.Generic;

using System.Numerics;

using UnityEngine;

public class moveRight : MonoBehaviour

{

public float speed = 0.5f;

public float xDestroyright = 12.0f;

// Start is called before the first frame update

void Start()

{

}

// Update is called once per frame

void Update()

{

//moves to the right

transform.Translate(UnityEngine.Vector3.right * speed);

if (transform.position.x > xDestroyright)

{

Destroy(gameObject);

}

}

}

Move down:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class moveDown : MonoBehaviour

{

public float speed = 5.0f;

private float yDestroy = -3.7f;

// Start is called before the first frame update

void Start()

{

}

// Update is called once per frame

void Update()

{

//moves to the left

transform.Translate(Vector3.down * speed);

//destroys if out of bounds

if (transform.position.y < yDestroy)

{

Destroy(gameObject);

}

}

}

Player Controller:

using System.Collections;

using System.Collections.Generic;

using System.Numerics;

using System.Runtime.CompilerServices;

using UnityEngine;

using TMPro;

using UnityEngine.SocialPlatforms.Impl;

using UnityEngine.UI;

using UnityEngine.SceneManagement;

public class PlayerController : MonoBehaviour

{

public float speed = 5.0f; //clean up later, make all private

public float topBound = 6.0f;

public float lowerBound = -3.7f;

public float verticalBound = 12;

private Rigidbody playerRb;

private int score;

public TextMeshProUGUI scoreText;

public ParticleSystem pointParticle;

public ParticleSystem aliencollision;

public TextMeshProUGUI gameOverText;

public static bool GameActive;

public Button playAgain;

public Button startGame;

public GameObject titleScreen;

public Button Exit;

// Start is called before the first frame update

void Start()

{

GameActive = false;

UpdateScore(0);

playerRb = GetComponent<Rigidbody>();

}

// Update is called once per frame

void Update()

{

if (GameActive)

{

playerMovement();

boundaries();

}

}

// gets the movement of the player from arrow keys

void playerMovement()

{

float horizontalInput = Input.GetAxis("Horizontal");

float verticalInput = Input.GetAxis("Vertical");

// moves the player up and down

transform.Translate(UnityEngine.Vector3.up * Time.deltaTime * speed * verticalInput);

//moves the player left and right

transform.Translate(UnityEngine.Vector3.right * Time.deltaTime * speed * horizontalInput);

}

// sets the boundaries of the player

void boundaries()

{

if (transform.position.y < lowerBound)

{

transform.position = new UnityEngine.Vector3(transform.position.x, lowerBound, transform.position.z);

}

else if (transform.position.y > topBound)

{

transform.position = new UnityEngine.Vector3(transform.position.x, topBound, transform.position.z);

}

else if (transform.position.x < -verticalBound)

{

transform.position = new UnityEngine.Vector3(-verticalBound, transform.position.y, transform.position.z);

}

else if (transform.position.x > verticalBound)

{

transform.position = new UnityEngine.Vector3(verticalBound, transform.position.y, transform.position.z);

}

}

//finally fucking works after like 3hrs of debugging

//use chained conditionals in onTrigger, Oncollider doesn't work

private void OnTriggerEnter(Collider other)

{

if (GameActive)

{

if (other.gameObject.CompareTag("Star"))

{

Destroy(other.gameObject);

UpdateScore(5);

Instantiate(pointParticle, transform.position, pointParticle.transform.rotation);

}

if (other.gameObject.CompareTag("Enemy"))

{

if (GameActive)

{

Instantiate(aliencollision, transform.position, aliencollision.transform.rotation);

}

Destroy(other.gameObject);

Debug.Log("Player has collided with the enemy.");

gameOverText.gameObject.SetActive(true);

playAgain.gameObject.SetActive(true);

GameActive = false;

UpdateScore(0);

}

}

}

private void UpdateScore(int scoreToAdd)

{

score += scoreToAdd;

scoreText.text = "Score: " + score;

}

public void RestartGame()

{

SceneManager.LoadScene(SceneManager.GetActiveScene().name);

GameActive = true;

}

public void destroyButton()

{

GameActive = true;

titleScreen.gameObject.SetActive(false);

}

public void doExitGame()

{

Application.Quit();

Debug.Log("Game is closing");

}

}
