平滑步行動畫統一（2D Unity在C＃中）

Question

所以我們要做的就是讓我們的玩家角色在走路時能夠平滑移動。步行由用戶通過箭頭鍵輸入口述。她有一個動畫課程和一個對撞機班，以保持她的步行週期，並讓她留在遊戲板上。問題在於，它只會一次移動一個猛擊動作，而不是在箭頭鍵向下幫助時繼續移動。有什麼建議麼？

你的代碼有可能被清理了幾個問題。但要解決您的代碼問題，您只需將更新循環更改爲以下內容即可。

void Update() 
{ 
    if(!isMoving) 
    { 
     CheckInput(); 

     if(isMoving) 
     { 
      input = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical")); 
      if(!allowDiagonals) 
      { 
       if(Mathf.Abs(input.x) > Mathf.Abs(input.y)) 
       { 
        input.y = 0; 
       } else 
       { 
        input.x = 0; 
       } 
      } 

      StartCoroutine(move(transform)); 
     } 
    } 
}
