Shooting using C# Script

■ Create Empty Object “Launcher” Drag the Launcher object onto the Main Camera object that

belongs to the FPS Controller in the Hierarchy panel

■ Create Bullets Using Prefabs Create Bullets

• Game Object > Create Other > Sphere “bullet” scale 0.2 Attach a rigid body component to the “bullet”

• Component > Physics > RigidBody Create New folder “Prefabs”

• Create New Prefab “prefabBullet”• drag and drop the bullet game object from the Hierarchy

window onto the bullet prefab in the Project window Delete the bullet game object in the Hierarchy window.

Shooting using C# Script

Select “Launcher” Object Create C# Script “createBullet”

• Add Component > New script• Open MonoDevelop• “prefabBullet” is assigned to the prefab Bullet variable in

the scriptusing UnityEngine;using System.Collections;

public class createBullet : MonoBehaviour { public Rigidbody prefabBullet; public float bulletForce = 1000.0f; void Update() { if (Input.GetButtonDown("Fire1")) { // 총알 오브젝트 (InstanceBullet) 생성 Rigidbody instanceBullet = Instantiate(prefabBullet, transform.position, transform.rotation) as Rigidbody; instanceBullet.AddForce(transform.forward * bulletForce); // 총알 오브젝트 앞으로 발사하는 힘 추가 Physics.IgnoreCollision ( instanceBullet.collider,transform.root.collider ); // Player 와의 충돌 무시 } }}

Launcher 로부터 총알 (Bullet) 발사

Make Tagret Objects

Create Empty Object “Target Create Game Object Cube “box”

• Attach a rigid body component to the “box” Create Prefab “Box”

Duplicate “box” object

총알과의 충돌 오브젝트 (Target) 생성

Explosion

■ Add Explosion Effect Select perfabBullet Add C# Script “Projectile” & Open MonoDevelop Import Standard Assets Particles Select “explosion” prefab Drag & Drop “Explosion” variable

using UnityEngine;using System.Collections;public class Projectile : MonoBehaviour {

public GameObject explosion;

void OnCollisionEnter( Collision collision) { ContactPoint contact = collision.contacts[0]; // 총알과의 충돌지점 Quaternion rotation = Quaternion.FromToRotation( Vector3.up, contact.normal ); // 충돌지점의 방향 GameObject instantiatedExplosion = Instantiate(

explosion, contact.point, rotation ) as GameObject; // 충돌후 폭파 (instantiateExplosion) 오브젝트 생성 Destroy(gameObject); // 총알 오브젝트 제거 }}

충돌 파티클 생성

Explosion

■ Destroy explosion prefab Select “explosion” prefab Add C# Script “Explosion” & Open MonoDevelop

■ Select “Max” Enemy Attach a rigid body component to the “Max”

• Check Freeze Rotation X,Y,Z• Check Gravity

Attach Box Collider component Max 오브젝트에 “ Enemy” tag 달기

■ 총알과의 충돌 감지 : Projectile Script 변경public class Projectile : MonoBehaviour { // 중략 …… public int damage=10; void OnCollisionEnter( Collision collision) {// 중략 …… if(collision.gameObject.tag == "Enemy"){

// 총알과 Enemy 테그와 충돌감지시 “ TakeDamage 함수” 호출 collision.gameObject.SendMessage( "TakeDamage", damage, SendMessageOptions.DontRequireReceiver ); } Destroy(gameObject); // 총알 오브젝트 제거 }}

총알 충돌에 의한 적군 체력치 감소

Enemy Health

■ Displaying GUI Create Empty “DisplayGUI” & Reset Create GUI Text “EnemyHealthText”

• Making Child: Drag into “Display Text”• Change Transform : X1, Y1• Change GUIText

Pixel Offset X-10, Y-10

• Anchor: upper right

■ Select “Max” Enemy Add C# Script “ApplyDamage” Assign “EnemyhealthText”

using UnityEngine;using System.Collections;

public class ApplyDamage : MonoBehaviour { public int health =50; public GUIText enemyhealthText;

void Start() { enemyhealthText.text =""; } void TakeDamage (int damage) { health -= damage; enemyhealthText.text = "Enemy Health: “ + health.ToString(); if(health <= 0) Destroy(gameObject);}

Player Health

■ Select Player “Hero” Attach Box Collider component Add C# Script

“PlayerHealthControl”

using UnityEngine;using System.Collections;

public class PlayerHealthControl : MonoBehaviour { public int curHealth = 100; public int maxHealth = 100; public GUIText healthText; public GUIText gameoverText; public int damage=10; void Start() { gameoverText.text=""; } void OnCollisionEnter(Collision hit){ // 플레이어와 Enemy 충돌 감지 if(hit.gameObject.tag == "Enemy"){ curHealth -= 10; } } void Update () { healthText.text = "Health " + curHealth.ToString() + " / " + maxHealth.ToString(); if ( curHealth <= 0 ) { gameoverText.text = "Game Over"; // Destroy( gameObject ); } }}

적군과의 충돌에 의한 플레이어 체력치 감소

Player Health

Create GUI Text “GameOverText”• Change Transform : X0.5, Y0.5• Change GUIText

Anchor middle center Alignment center Font Size 50

■ Select “Hero” & Assign GUI Text

Game Over & Restart

using UnityEngine;using System.Collections;

public class PlayerHealthControl : MonoBehaviour { public int curHealth = 100; public int maxHealth = 100; public GUIText healthText; public GUIText gameoverText; public int damage=10; private bool gameOver; void Start() { gameoverText.text=""; gameOver = false; } void OnCollisionEnter(Collision hit){ if(hit.gameObject.tag == "Enemy“) curHealth -= 10;

}

void Update () { healthText.text = "Health " + curHealth.ToString() + " / " + maxHealth.ToString(); // ToString() if ( curHealth <= 0 ) { gameoverText.text = "Game Over"; healthText.text = "Press 'R' for Restart"; gameOver = true; if (gameOver) { if (Input.GetKeyDown (KeyCode.R)) { Application.LoadLevel (Application.loadedLevel); } } } }}

Enemy AI

■ Enemy AI Using Rain {indie}

1. Create it from the RAIN Menu

2. Locate it within the Hierarchy

3. Modify it using the Component or Element within the Inspector.

Enemy AI

■ Creating AI Create Capsule Game Object “NPC”

1. In the RAIN menu, select Create AI.

2. AI object on your GameObject in the hierarchy.

3. Selecting the AI object on your GameObject in the hierarchy will display the AIRig component in the Inspector.

4. Within the AIRig component, you will find the basic 6 elements, and an additional custom element.

Enemy AI

■ Creating Waypoints In the RAIN menu, select either Create Waypoint Network or

Create Waypoint Route. “NPCWayPoint”• This will add a Waypoint object in the hierarchy.

Selecting “NPCWayPoint” Waypoint Rig editor component in the Inspector.

Within the Waypoint Rig component:• You add waypoints.• Modify waypoint vector position.• Edit the color.• Drop waypoints• Edit their radius.

Enemy AI

■ Adding Waypoints Click the Add (Ctrl W) button in the Waypoint rig. This creates a waypoint at the center of your camera and

attempts to get it close to the ground. select Drop To Surface.

Enemy AI

■ Creating a Navigation Mesh1. In the RAIN menu, select Create Navigation Mesh.

Size and Mesh Color for starters. (“Plane” 과 같은 크기로 설정 )

5. Click Generate Navigation Mesh to create.

Navigation Mesh help with movement across small or large areas quickly while avoiding static obstacles.

Enemy AI

■ Creating Behavior Open the Behavior Tree Editor by selecting from the menu

RAIN » Behavior Tree Editor. You can also access a shortcut from the AI Mind.

Create a new behavior tree by selecting it from the drop down. This will create a basic tree with a sequencer container in it. “NPCBehavior”

Enemy AI

Select root & Right click Create Actions Choose Patrol Waypoints Set the property of Patrol Route

• Name “NPCPatrol” , Waypoint Route “NPCWaypoint”• Loop Type “Loop”• Move Target Variable “nextStop”

Enemy AI

Add Action move • Move Target “nextStop”• Move speed “2”

Add Action animate : Animation state “walk”
