Jump Game

本文探讨如何通过数组元素表示跳跃长度,解决从第一个位置到达最后一个位置的路径问题。通过实例演示,读者可以掌握如何判断是否能成功完成跳跃游戏。

Given an array of non-negative integers, you are initially positioned at the first index of the array.

Each element in the array represents your maximum jump length at that position.

Determine if you are able to reach the last index.

For example:
A = [2,3,1,1,4], return true.

A = [3,2,1,0,4], return false.

class Solution {
public:
    bool canJump(int A[], int n) {
        // Start typing your C/C++ solution below
        // DO NOT write int main() function
        if (A[0] == 0 && n > 1) {
            return false;
        }
        for (int i = 1; i < n; ++i) {
            A[i] = A[i] + i > A[i-1] ? A[i] + i : A[i-1];
            if (A[i] == i && i != n-1) {
                return false;
            }
        }
        return true;
    }
};


以下是C#跳跃游戏的源代码: using System.Collections; using System.Collections.Generic; using UnityEngine; public class PlayerController : MonoBehaviour { public float jumpForce = 10f; public float moveSpeed = 5f; public Transform groundCheck; public LayerMask groundLayer; public GameObject gameOverPanel; private Rigidbody2D rb; private Animator anim; private bool isJumping = false; private bool isGrounded = false; void Start() { rb = GetComponent<Rigidbody2D>(); anim = GetComponent<Animator>(); } void Update() { if (Input.GetKeyDown(KeyCode.Space) && isGrounded) { isJumping = true; rb.velocity = Vector2.up * jumpForce; } anim.SetBool("isJumping", isJumping); anim.SetFloat("yVelocity", rb.velocity.y); float horizontalInput = Input.GetAxisRaw("Horizontal"); rb.velocity = new Vector2(horizontalInput * moveSpeed, rb.velocity.y); if (rb.velocity.x > 0) { transform.localScale = new Vector3(1, 1, 1); } else if (rb.velocity.x < 0) { transform.localScale = new Vector3(-1, 1, 1); } isGrounded = Physics2D.OverlapCircle(groundCheck.position, 0.1f, groundLayer); if (!isGrounded) { gameOverPanel.SetActive(true); Time.timeScale = 0f; } } private void OnTriggerEnter2D(Collider2D collision) { if (collision.CompareTag("Coin")) { Destroy(collision.gameObject); } } } 在此代码中,我们定义了玩家控制器的变量和属性。我们还定义了开始和更新函数,以便在游戏中实现跳跃和移动。我们还在代码中添加了碰撞检测和游戏结束的逻辑。
