Unityで2DRPGを作ってみる 3日目
昨日までのところで、キャラクターの見た目のところは出来たので、今日はインプット関連のスクリプトを書いていきます。
それだけだとすぐ終わってしまうので、適当に歩き回る村人も作ります。
CharacterControlの作成
プレイヤーと村人で共通の処理があるので、CharacterControlというクラスを作り、プレイヤーと村人はそれを継承する形にします。
CharacterControl.cs

using UnityEngine;
public class CharacterControl : MonoBehaviour {
public float m_speed;
protected Animator m_animator;
protected float m_directionX = 0;
protected float m_directionY = 0;
protected bool m_walking = false;
protected void Awake() {
this.m_animator = GetComponent();
}
protected void Update () {
if(this.m_animator){
if(this.m_walking){
transform.Translate(new Vector3(this.m_directionX, this.m_directionY, 0) * Time.deltaTime * m_speed);
transform.position = new Vector3(transform.position.x,transform.position.y,transform.position.y / 1000f);
}
this.m_animator.SetFloat("DirectionX", this.m_directionX);
this.m_animator.SetFloat("DirectionY", this.m_directionY);
this.m_animator.SetBool("Walking", this.m_walking);
}
}
}
PlayerControlの作成
Unityには、Inputクラスというのがあり、これを使うとインプット関係のコーディングが非常に楽です。
Input.GetAxisに、"Horizontal"を入れるとX軸の入力が、"Vertical"を入れるとY軸の入力が分かります。
この値を利用するPlayerControlクラスを作成します。
PlayerControl.cs

using UnityEngine;
public class PlayerControl : CharacterControl {
new void Update () {
if(this.m_animator){
// 入力の取得
float horizontal = Input.GetAxis("Horizontal");
float vertical = Input.GetAxis("Vertical");
this.m_walking = true;
if(horizontal==0 && vertical==0){
this.m_walking = false;
}else{
this.m_directionX = horizontal;
this.m_directionY = vertical;
}
}
base.Update();
}
}
VillagerControlの作成
次に村人を作りますが、その前に昨日作成したGameObjectの名前をCharacterBaseに変更し、Prefabとして保存します。
それから、HierarchyのCharacterBaseの名前をPlayerに変更し、CharacterBaseをPrefabからHierarchyにD&Dします。
新しく出来たCharacterBaseの名前をVillager01にします。キャラクタの画像はデフォルトでpipo-charachip001になっているので、Villager01のCharacterスクリプトのImageを、pipo-charachip002などに変更します。
この村人に設定するスクリプトを作成します。
VillagerControl.cs

using UnityEngine;
using System.Collections;
public class VillagerControl : CharacterControl {
private float m_defaultSpeed;
void Start () {
this.m_defaultSpeed = this.m_speed;
StartCoroutine("Walk");
}
private IEnumerator Walk(){
for(;;){
this.m_walking = true;
this.m_speed = this.m_defaultSpeed * Random.Range (0.5f,1f);
this.m_directionX = Random.Range (-1f,1f);
this.m_directionY = Random.Range (-1f,1f);
yield return new WaitForSeconds(Random.Range(0f,5f));
this.Wait();
yield return new WaitForSeconds(Random.Range(0f,5f));
}
}
private void Wait(){
this.m_walking = false;
}
}
村人の動きとしては、ランダムに移動量と移動方向を決めて、0～5秒間でランダムに移動し、0～5秒間をランダムに停止すると言うのを繰り返します。
こういう動作はイテレータを使用したコルーチンを使うことで実現できます。
作成したスクリプトの割り当て
作成したスクリプトを割り当てます。PlayerオブジェクトにPlayerControl.csを
Villager01オブジェクトにVillager01オブジェクトを割り当てます。
割り当てたら、PlayerのSpeedを128、Villager01のSpeedを32にします。
ここまで出来ましたら、再生ボタンを押すと、村人が自動的に歩き出すと思います。カーソルキーを押すことで、Playerを操作できます。
今は当たり判定を付けていないので、お互いにすり抜けることが出来ます。
次回はフィールドマップの作成をする予定です。(行き詰まっているので、公開まで時間がかかるかも…)
