最近工作中的新需求,手指触摸屏幕选中物体跟随手指移动的任务,开发完成后便记录下来,大家共勉
public class TouchTest : MonoBehaviour
{
public Transform currTouchObj;
private Camera mainCamera;
private void Awake()
{
mainCamera = Camera.main;
}
public void CtrlTouchObjMove()
{
if (Input.touchCount == 1)
{
Touch firstTouch = Input.GetTouch(0);
if (firstTouch.phase == TouchPhase.Began)
{
Ray ray = mainCamera.ScreenPointToRay(firstTouch.position);
RaycastHit hit;
if (Physics.Raycast(ray, out hit))
{
//获取当前触摸到的物体
currTouchObj = hit.collider.transform;
}
}
if (Input.GetTouch(0).phase == TouchPhase.Moved)
{
if (currTouchObj)
{
Vector3 touchDeltaPos = Input.GetTouch(0).deltaPosition;
currTouchObj.Translate(touchDeltaPos.x * touchObjMoveSpeed, touchDeltaPos.y * touchObjMoveSpeed, 0, Space.World);
}
}
}
}
