Unity3D各種獲取鼠標各種位置的小方法

Vector3 screenPosition; //將物體從世界坐標轉換為屏幕坐標

 

Vector3 mousePositionOnScreen; //獲取到點擊屏幕的屏幕坐標

 

Vector3 mousePositionInWorld; //將點擊屏幕的屏幕坐標轉換為世界坐標

 

void Update()

 

{

 

MouseFollow();

 

}

 

void MouseFollow()

 

{

 

//獲取鼠標在相機中（世界中）的位置，轉換為屏幕坐標；

 

screenPosition = Camera.main.WorldToScreenPoint(transform.position);

 

//獲取鼠標在場景中坐標

 

mousePositionOnScreen = Input.mousePosition;

 

//讓場景中的Z=鼠標坐標的Z

 

mousePositionOnScreen.z = screenPosition.z;

 

//將相機中的坐標轉化為世界坐標

 

mousePositionInWorld = Camera.main.ScreenToWorldPoint(mousePositionOnScreen);

 

//物體跟隨鼠標移動

 

//transform.position = mousePositionInWorld;

 

//物體跟隨鼠標X軸移動

 

transform.position = new Vector3(mousePositionInWorld.x,transform.position.y,transform.position.z);
