现在记忆力越来越差，写过很多遍的内容，都有可能需要慢慢才能想起来，这里就记录下在unity开发过程中一些小的知识点
一、获取unity层级和layerMask
int ground = LayerMask.NameToLayer("Ground");
int groundMask = 1<<ground;
二、获取鼠标拾取位置
public static class ULayerMask
{
public static int Ground = LayerMask.NameToLayer("Ground");
public static int GroundMask = 1<<LayerMask.NameToLayer("Ground");public static int Wall = LayerMask.NameToLayer("Wall");
public static int WallMask = 1 << Wall;
public static int CollisionMask = 1<< Ground | 1<< Wall;
}
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit,1000f,ULayerMask.CollisionMask))
{
ULog.Error("astar");
foreach (var actor in charactors.GetActors())
{
actor.Astar?.BeginPath(hit.point);
}
}
三、获取触摸输入的位置
for (var i = 0; i < Input.touchCount; ++i)
{if (Input.GetTouch(i).phase == TouchPhase.Began){// Construct a ray from the current touch coordinatesRay ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);// Create a particle if hitif (Physics.Raycast(ray)){//ULog.Info(ray.ToString());}}
}
四、FariyGui 判断鼠标等输入设备是否在UI之上
Stage.isTouchOnUI
五、fairyGui动态创建UIPanel
GameObject uiObject = new GameObject();
uiObject.layer = ULayerMask.UI;
UIPanel uiPanel = uiObject.AddComponent<UIPanel>();uiPanel.packageName = package;
uiPanel.componentName = componentName;uiPanel.CreateUI();
六、fairyGui为控件添加Touch事件
GObject _touchArea;
_touchArea.onTouchBegin.Add(this.OnTouchBegin);
_touchArea.onTouchMove.Add(this.OnTouchMove);
_touchArea.onTouchEnd.Add(this.OnTouchEnd);
七 C#中??的使用
a??b;
当a不为空时返回a,否则返回b
八、C#中 ?. 的使用
a?.name
如果a为空返回空，否则返回a.name
string name = a?.name;
九、如何对泛型进行约束
约束为T必须继承BaseComponent，并且带默认构造函数
public void RemoveComponent<T>() where T : BaseComponent,new()
{
RemoveComponent(typeof(T));}
十、绕y轴选旋转一定角度
public void RotationY(float angle)
{transform.rotation = Quaternion.Euler(Vector3.up * (angle % 360));
}
