C# 统一RTS全面战争风格点击和拖动部队编队
我一直在unity工作，试图通过点击和拖动来实现单位队形宽度/深度创建的全面战争风格，如本视频中15秒左右所示： 我已经写了一些代码，但我正在摆脱索引错误。到目前为止：C# 统一RTS全面战争风格点击和拖动部队编队,c#,unity3d,C#,Unity3d,我一直在unity工作，试图通过点击和拖动来实现单位队形宽度/深度创建的全面战争风格，如本视频中15秒左右所示： 我已经写了一些代码，但我正在摆脱索引错误。到目前为止： using System.Collections; using System.Collections.Generic; using UnityEngine; public class Formation : MonoBehaviour { // Use this for initialization voi
