21. UI 만들기

Canvas 생성 후 텍스트, 버튼 생성하고 Anchor로 위치잡아주기

 

 

UI 접근 코드는 GameManager 스크립트에서 작성

소스코드

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI; //UI에 접근하기 위해 필요

public class GameManager : MonoBehaviour
{

    public int totaltemCount;
    public int stage;
    public Text stageCountText; //전체 Item 개수 
    public Text playerCountText; // 현재 플레이어가 먹은 Item 개수

    void Awake()
    {
        stageCountText.text = "/ " + totaltemCount;
    }

    public void getItem(int count) { //Player 스크립트에서 함수 호출
        if (count >= 10) {
            stageCountText.text = "  / " + totaltemCount;
        }
        playerCountText.text = count.ToString();
    }

    public void stageReset() { 
        SceneManager.LoadScene(stage);
    }

    public void goToStage0() {
        SceneManager.LoadScene(0);
    }

    public void exit() {
        Application.Quit();
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Player") {
            SceneManager.LoadScene(stage);
        }
    }


}

 

Player 소스코드 추가 (주석부분)

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

public class PlayerBall : MonoBehaviour
{
    Rigidbody rigid;
    AudioSource audio; 
    public GameManager gm;
    public float jumpPower;
    bool isJumping;
    public int itemCount;

    void Awake()
    {
        rigid = GetComponent<Rigidbody>();
        audio = GetComponent<AudioSource>(); 
        jumpPower = 30;
        isJumping = false;
        itemCount = 0;
    }

    void FixedUpdate()
    {
        float x = Input.GetAxisRaw("Horizontal");
        float z = Input.GetAxisRaw("Vertical");
        Vector3 move = new Vector3(x, 0, z);

        rigid.AddForce(move, ForceMode.Impulse);

    }

    void Update()
    {
        if (Input.GetButtonDown("Jump") && !isJumping)
        {
            isJumping = true;
            rigid.AddForce(new Vector3(0, jumpPower, 0), ForceMode.Impulse);
        }
    }

    void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Floor")
        {
            isJumping = false;
        }
    }
    void OnTriggerEnter(Collider other)
    {
        if (other.tag == "Item")
        {
            itemCount++;
            audio.Play();
            gm.getItem(itemCount); //플레이어가 Item을 먹을 때마다 GameManager 스크립트의 getItem 호출, itemCount를 매개변수로 줌
            other.gameObject.SetActive(false);
        }
        else if(other.tag == "Finish") //스테이지 이동 로직
        { 
            if (gm.totaltemCount == itemCount) {
                //Game Clear!
                if (gm.stage == 2)
                {
                    Debug.Log("You won! Stage Reset");
                    SceneManager.LoadScene(0);
                }
                else
                {
                    SceneManager.LoadScene(gm.stage + 1);
                }
            }
            else {
                SceneManager.LoadScene(gm.stage);
            }
        }

    }
}
