地圖添加Tilemap Collider 2D

快速創建主角及動畫?

起個名字保存一下?

界面上已經有人物了，點擊運行，可以看到idle動畫，給人物idle添加Circle Collider 2d和Rigidbody 2D，然后將idle重命名為player,設置Rigidbody 2D的z軸鎖定，防止移動時翻跟頭

動畫拖不進去的解決辦法，不知道為什么，教程可以直接拖進去，我的就是不行，應該是沒找對方法，可以通過另種方法實現動畫制作

拖動所有素材到Hierarchy

起個名字

刪掉沒有的動畫等

修改playerAnimation動畫,run后期修改成了runing類型改成float了，方便動畫切換

把條件統統設置上去，并且動畫切換時間改為0

run->idle

idle->run

jump->idle

idle->jump

run->jump

jump->run

給主角添加腳本

安裝屏幕方向組件，assetstore搜索Joystick Pack添加到我的資源，導入到項目

添加Canvas并將Variable joystick拖動給Canvas

調整分辨率和Joystick位置

Cravity Scale重力修改為3方便快速下落

添加一個Background圖層

將地圖設置到Background圖層

將資源幅值給player中的腳本

代碼

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI;public class PlayerControler : MonoBehaviour {[SerializeField] private Rigidbody2D PlayerRd;[SerializeField] private Animator PlayerAnimator;public Collider2D PlayerCollider;public float Speed;public float Jumpforce;public LayerMask Ground;public VariableJoystick variableJoystick;// Start is called before the first frame updatevoid Start(){PlayerRd = GetComponent<Rigidbody2D>();PlayerAnimator = GetComponent<Animator>();}// Update is called once per framevoid Update(){Movement();SwithcAnim();}void Movement(){float horizontalMove = variableJoystick.Horizontal;float verticalMove = variableJoystick.Vertical;#region 設置PlayerRd.velocity = new Vector2(horizontalMove * Speed * Time.deltaTime, PlayerRd.velocity.y);PlayerAnimator.SetFloat("runing", Mathf.Abs(PlayerRd.velocity.x));//跳躍和落地if (verticalMove > 0.5f && ((PlayerCollider.IsTouchingLayers(Ground)))){PlayerRd.velocity = new Vector2(PlayerRd.velocity.x, Jumpforce);}if (horizontalMove > 0){transform.localScale = new Vector3(1, 1, 1);}else if (horizontalMove < 0){transform.localScale = new Vector3(-1, 1, 1);}#endregion}void SwithcAnim(){if (PlayerCollider.IsTouchingLayers(Ground)){PlayerAnimator.SetBool("jump", false);}else if(Mathf.Abs(PlayerRd.velocity.y) > 10){PlayerAnimator.SetBool("jump", true);}} }

最終效果

有時走動會發現忽快忽慢，是因為碰撞器產生了向上的力后地面的摩擦力就小了，有一種比較簡單的解決辦法，就是直接改變player的位置，修改后的代碼

void Movement(){float horizontalMove = variableJoystick.Horizontal;float verticalMove = variableJoystick.Vertical;#region 設置PlayerRd.transform.position = new Vector2(horizontalMove * Speed * Time.deltaTime + PlayerRd.transform.position.x, PlayerRd.transform.position.y);PlayerAnimator.SetFloat("runing", Mathf.Abs(horizontalMove));//跳躍和落地if (verticalMove > 0.5f && ((PlayerCollider.IsTouchingLayers(Ground)))){PlayerRd.velocity = new Vector2(PlayerRd.velocity.x, Jumpforce);}if (horizontalMove > 0){transform.localScale = new Vector3(1, 1, 1);}else if (horizontalMove < 0){transform.localScale = new Vector3(-1, 1, 1);}#endregion}

需要調整一下速度值
