bombCrate -> crate, parachute

FloatDown 애니(떨어질때 흔들흔들하는모션) 와 BombLanding(떨어지고 나서 낙하산이 없어지는모션) 애니로 구성되있음

using UnityEngine;
using System.Collections;

public class BombPickup : MonoBehaviour
{
	public AudioClip pickupClip;		// Sound for when the bomb crate is picked up.

private Animator anim;				// Reference to the animator component.
	private bool landed = false;		// Whether or not the crate has landed yet.

void Awake()
	{
		// Setting up the reference.
		anim = transform.root.GetComponent<Animator>();
	}

void OnTriggerEnter2D (Collider2D other)
	{
		// If the player enters the trigger zone...
		if(other.tag == "Player")
		{
			// ... play the pickup sound effect.
			AudioSource.PlayClipAtPoint(pickupClip, transform.position);

// Increase the number of bombs the player has.
			other.GetComponent<LayBombs>().bombCount++;

// Destroy the crate.
			Destroy(transform.root.gameObject);
		}
		// Otherwise if the crate lands on the ground...
		else if(other.tag == "ground" && !landed)
		{
			// ... set the animator trigger parameter Land.
			anim.SetTrigger("Land");
			transform.parent = null;
			gameObject.AddComponent<Rigidbody2D>();
			landed = true;		
		}
	}
}

landed -> 현재 땅인지 체크

폭탄은 서클 콜라이더와 박스 콜라이더로 구성되있고 서클콜라이더는 is Trigger 체크 되있음

그래서 OnTriggerEnter 함수를 호출할수잇음. 박스콜라이더는 땅과 부딪히게 할려고 부착한 상태인듯. isTrigger 시 충돌 무시해버리고 통과되기때문.

Player 와 부딪힐 경우에는 플레이어의 폭탄 개수를 늘려주고 삭제해버림.

그리고 땅과 부딪힐경우에는 else if(other.tag == "ground" && !landed)

Ladn 애니메이션을 실행시키고

Create 폭탄의 부모 오브젝트를 null값으로 만들어준다.

그리고 리지드바디를 추가시킴(추가가 안될시 플레이어와 물리효과를 집어널수없기때문,.)

explosionParticle -> 은 히어라이키에 한개만 존재함 이함수를 재활요해서 계속 사용함

using UnityEngine;
using System.Collections;

public class Bomb : MonoBehaviour
{
	public float bombRadius = 10f;			// Radius within which enemies are killed.
	public float bombForce = 100f;			// Force that enemies are thrown from the blast.
	public AudioClip boom;					// Audioclip of explosion.
	public AudioClip fuse;					// Audioclip of fuse.
	public float fuseTime = 1.5f;
	public GameObject explosion;			// Prefab of explosion effect.

private LayBombs layBombs;				// Reference to the player's LayBombs script.
	private PickupSpawner pickupSpawner;	// Reference to the PickupSpawner script.
	private ParticleSystem explosionFX;		// Reference to the particle system of the explosion effect.

void Awake ()
	{
		// Setting up references.
		explosionFX = GameObject.FindGameObjectWithTag("ExplosionFX").GetComponent<ParticleSystem>();
		pickupSpawner = GameObject.Find("pickupManager").GetComponent<PickupSpawner>();
		if(GameObject.FindGameObjectWithTag("Player"))
			layBombs = GameObject.FindGameObjectWithTag("Player").GetComponent<LayBombs>();
	}

void Start ()
	{
		
		// If the bomb has no parent, it has been laid by the player and should detonate.
		if(transform.root == transform)
			StartCoroutine(BombDetonation());
	}

IEnumerator BombDetonation()
	{
		// Play the fuse audioclip.
		AudioSource.PlayClipAtPoint(fuse, transform.position);

// Wait for 2 seconds.
		yield return new WaitForSeconds(fuseTime);

// Explode the bomb.
		Explode();
	}

public void Explode()
	{
		
		// The player is now free to lay bombs when he has them.
		layBombs.bombLaid = false;

// Make the pickup spawner start to deliver a new pickup.
		pickupSpawner.StartCoroutine(pickupSpawner.DeliverPickup());

// Find all the colliders on the Enemies layer within the bombRadius.
		Collider2D[] enemies = Physics2D.OverlapCircleAll(transform.position, bombRadius, 1 << LayerMask.NameToLayer("Enemies"));

// For each collider...
		foreach(Collider2D en in enemies)
		{
			// Check if it has a rigidbody (since there is only one per enemy, on the parent).
			Rigidbody2D rb = en.rigidbody2D;
			if(rb != null && rb.tag == "Enemy")
			{
				// Find the Enemy script and set the enemy's health to zero.
				rb.gameObject.GetComponent<Enemy>().HP = 0;

// Find a vector from the bomb to the enemy.
				Vector3 deltaPos = rb.transform.position - transform.position;

// Apply a force in this direction with a magnitude of bombForce.
				Vector3 force = deltaPos.normalized * bombForce;
				rb.AddForce(force);
			}
		}

// Set the explosion effect's position to the bomb's position and play the particle system.
		explosionFX.transform.position = transform.position;
		explosionFX.Play();

// Instantiate the explosion prefab.
		Instantiate(explosion,transform.position, Quaternion.identity);

// Play the explosion sound effect.
		AudioSource.PlayClipAtPoint(boom, transform.position);

// Destroy the bomb.
		Destroy (gameObject);
	}
}

폭탄관련함수

if(transform.root == transform)

StartCoroutine(BombDetonation());

플레이어가 알트 버튼을 눌러서 폭파 시킬때 실행됨 최상위 오브젝트가 없을때(Create일때) -> LayBombs 스크립트에서 실행

Explode() -> 외부에서 실행됨 폭탄이 내려오는데 플레이어가 총으로 맞춘다던가

bombLaid 를 false로 만들어줌.

pickupSpawner -> 픽업매니저 스크립트 -> PickupSpawner 구급상자와 폭탄 생성

pickupSpawner.StartCoroutine(pickupSpawner.DeliverPickup()); -> 아이템 재생성

Collider2D[] enemies = Physics2D.OverlapCircleAll(transform.position, bombRadius, 1 << LayerMask.NameToLayer("Enemies"));

반경 원안에 있는 적들 배열에 집어넣기

foreach(Collider2D en in enemies)

{

// Check if it has a rigidbody (since there is only one per enemy, on the parent).

Rigidbody2D rb = en.rigidbody2D;

if(rb != null && rb.tag == "Enemy")

{

// Find the Enemy script and set the enemy's health to zero.

rb.gameObject.GetComponent<Enemy>().HP = 0;

// Find a vector from the bomb to the enemy.

Vector3 deltaPos = rb.transform.position - transform.position;

// Apply a force in this direction with a magnitude of bombForce.

Vector3 force = deltaPos.normalized * bombForce;

rb.AddForce(force);

}

적들의 체력을 0으로 만들고 적들을 튕겨내버림

explosionFX.transform.position = transform.position;

explosionFX.Play();

이펙트 위치 설정 및 실행

using UnityEngine;
using System.Collections;

public class LayBombs : MonoBehaviour
{
	[HideInInspector]
	public bool bombLaid = false;		// Whether or not a bomb has currently been laid.
	public int bombCount = 0;			// How many bombs the player has.
	public AudioClip bombsAway;			// Sound for when the player lays a bomb.
	public GameObject bomb;				// Prefab of the bomb.

private GUITexture bombHUD;			// Heads up display of whether the player has a bomb or not.

void Awake ()
	{
		// Setting up the reference.
		bombHUD = GameObject.Find("ui_bombHUD").guiTexture;
	}

void Update ()
	{
		// If the bomb laying button is pressed, the bomb hasn't been laid and there's a bomb to lay...
		if(Input.GetButtonDown("Fire2") && !bombLaid && bombCount > 0)
		{
			// Decrement the number of bombs.
			bombCount--;

// Set bombLaid to true.
			bombLaid = true;

// Play the bomb laying sound.
			AudioSource.PlayClipAtPoint(bombsAway,transform.position);

// Instantiate the bomb prefab.
			Instantiate(bomb, transform.position, transform.rotation);
		}

// The bomb heads up display should be enabled if the player has bombs, other it should be disabled.
		bombHUD.enabled = bombCount > 0;
	}
}

플레이어에 붙어있는 스크립트

bombLaid -> 폭탄 발사여부 - > Explode 함수가 실행되야 false로 변함

bombCount -> 폭탄 개수

알트 버튼 누르면 발사
