Question

我是团结的新手，我试图建立一种方法，通过2个手指触摸沿着x和z轴移动场景中的游戏对象。我想出了一个代码，我相信它在逻辑上是正确的，但不符合要求。请指出我的错误并告诉我最好的方法这是我提出的代码

if (Input.touchCount == 2) {
            // Two fingers
            Touch touch_1 = Input.GetTouch (0);
            Touch touch_2 = Input.GetTouch (1);

            mFingerPosition_1 = touch_1.position;
            mFingerPosition_2 = touch_2.position;
            mMidValue = (mFingerPosition_1 + mFingerPosition_2) / 2;



            //is moving

            if ((touch_1.phase == TouchPhase.Began)&&(touch_2.phase==TouchPhase.Began)) 
            {
                move = true;
            }
            else if ((touch_1.phase == TouchPhase.Ended)||(touch_2.phase==TouchPhase.Ended)) 
            {
                move = false;
            }

            //if moving

            if(move==true)
            {
                Vector2 Axis = touch_1.position - mFingerPosition_1;
                float yAxis = speed * touch_1.deltaPosition.y;
                float xAxis = speed * touch_1.deltaPosition.x;

                //moving on z axis
                if ((Axis.y > 0)||(Axis.y<0))
                {
                    float x = mARObject.transform.position.x;
                    float y = mARObject.transform.position.y;
                    float z = mARObject.transform.position.z;
                    mARObject.transform.position.Set (x,y,yAxis+z);
                }

                //moving on x axis
                else if((Axis.x>0)||(Axis.x<0))
                {
                    float x = mARObject.transform.position.x;
                    float y = mARObject.transform.position.y;
                    float z = mARObject.transform.position.z;
                    mARObject.transform.position.Set (xAxis+x,y,z);
                }
            }

            }

提前谢谢

Answer 1

Vector2 Axis = touch_1.position - mFingerPosition_1;将始终生成（0,0）delta矢量作为touch_1.position = mFingerPosition_1。而是尝试使用Touch.deltaPosition

用两根手指触摸并移动游戏对象
