关于Vector2...自问自答:是不是因为计算两向量的夹角时,都是从第一个向量顺时针走到第二个向量的角度?如果向量指向3点钟位置,与垂直向上的向量夹角就是270度。然后大炮原始角度也是垂直向上,转270度反而指向了9点钟方
假设你的2D方向是一个Vector2类型的变量direction,你可以使用以下代码将其转换为绕Z轴旋转的角度: float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg; 这个代码片段中,direction.y是方向的Y值,direction.x是方向的X值。Mathf.Rad2Deg用于将弧度转换为角度。

2.3.2 两种插件导入方式(项目中首次安装) 菜单式导入 在资源菜单Assets或者资源面板的Assets,右键import Package->customPackage,如下图所示。 (上图为从菜单导入) (上图为从资源面板导入) 以上的两种导入方式,任选一种点开后,选择之前下载好的LayaAir引擎unity插件(xx.unitypackage)打开,如下图所示。
