我有一個 3D 對象，我想用鼠標/手指滑動來旋轉它，所以我制作了下面的腳本。對象的旋轉在編輯器上看起來很流暢，但是在真實設備（android）上玩游戲時，旋轉并沒有立即跟隨手指移動，跟隨手指需要幾毫秒，它不流暢并且控制變得困難并且令人沮喪！float sensitivity = 0.8f;Vector2 firstPressPos;Vector2 secondPressPos;void Update(){ if (Input.GetMouseButtonDown(0)) { //save began touch 2d point firstPressPos = new Vector3(Input.mousePosition.x, Input.mousePosition.y); } if (Input.GetMouseButton(0)) { //save ended touch 2d point secondPressPos = new Vector3(Input.mousePosition.x, Input.mousePosition.y); if (firstPressPos != secondPressPos) { float RotX = Input.GetAxis("Mouse X") * sensitivity * Time.deltaTime; float RotY = Input.GetAxis("Mouse Y") * sensitivity * Time.deltaTime; transform.RotateAround(Vector3.up, RotX); transform.RotateAround(Vector3.right, -RotY); } }}

試試這個代碼
// Screen Touches
Vector2?[] oldTouchPositions = {
null,
null
};
// Rotation Speed
public float rotSpeed = 0.5f;
public void Update()
{
if (Input.touchCount == 0)
{
oldTouchPositions[0] = null;
oldTouchPositions[1] = null;
}
else if (Input.touchCount == 1)
{
if (oldTouchPositions[0] == null || oldTouchPositions[1] != null)
{
oldTouchPositions[0] = Input.GetTouch(0).position;
oldTouchPositions[1] = null;
}
else
{
Vector2 newTouchPosition = Input.GetTouch(0).position;
float distanceX = (oldTouchPositions[0] - newTouchPosition).Value.x;
float distanceY = (oldTouchPositions[0] - newTouchPosition).Value.y;
float rotX = distanceX * rotSpeed * Mathf.Deg2Rad;
float rotY = distanceY * rotSpeed * Mathf.Deg2Rad;
transform.Rotate(Vector3.up, rotX * 5, Space.Self);
transform.Rotate(Vector3.left, rotY * 5, Space.Self);
oldTouchPositions[0] = newTouchPosition;
}
}
else
{
if (oldTouchPositions[1] == null)
{
oldTouchPositions[0] = Input.GetTouch(0).position;
oldTouchPositions[1] = Input.GetTouch(1).position;
}
else
{
}
}
}

這是我幾年前發現的一個腳本，它使用鼠標或觸摸操作 X 軸旋轉。它似乎適用于觸摸，但不適用于鼠標。嘗試一下，讓我知道它是否表現更好。這個應該動態調整旋轉速度：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class SpinDrag : MonoBehaviour {
float f_lastX = 0.0f;
float f_difX = 0.5f;
float f_steps = 0.0f;
int i_direction = 1;
// Use this for initialization
void Start()
{
}
// Update is called once per frame
void Update()
{
if (Input.GetMouseButtonDown(0))
{
f_difX = 0.0f;
}
else if (Input.GetMouseButton(0))
{
f_difX = Mathf.Abs(f_lastX - Input.GetAxis("Mouse X"));
if (f_lastX < Input.GetAxis("Mouse X"))
{
i_direction = -1;
transform.Rotate(Vector3.up, -f_difX);
}
if (f_lastX > Input.GetAxis("Mouse X"))
{
i_direction = 1;
transform.Rotate(Vector3.up, f_difX);
}
f_lastX = -Input.GetAxis("Mouse X");
}
else
{
if (f_difX > 0.5f) f_difX -= 0.05f;
if (f_difX < 0.5f) f_difX += 0.05f;
transform.Rotate(Vector3.up, f_difX * i_direction);
}
}
}
