[游戏开发]Unity中location和rotation赋值和更改

Unity中location可以和Vector3向量相加减和 通过new Vector3更改位置。如：

public Vector3 cubeposition = new Vector3(0,0,0);

cubeposition = new Vector3(Xadjustposition, Yadjustposition, Zadjustposition);
?GameObject.Find("newcube").transform.position = cubeposition;

但rotation不行，要用Quaternion.Euler赋值的办法才能赋值或更改角度。如：

public Quaternion cuberotation = Quaternion.identity;//四元素初始化只能这样

cuberotation = Quaternion.Euler(Xadjustrotation, Yadjustrotation, Zadjustrotation);

GameObject.Find("newcube").transform.localRotation=cuberotation;

或者GameObject.Find("newcube").transform.localRotation=Quaternion.Euler(Xadjustrotation, Yadjustrotation, Zadjustrotation);

综合：

GameObject.Find("newcube").transform.localPosition = cuberotation * new Vector3(translation.y, translation.z, -translation.x) + cubeposition;

下面是更完整一点儿的摘抄：

float Xadjustposition, Yadjustposition, Zadjustposition, Xadjustrotation, Yadjustrotation, Zadjustrotation;
?public Vector3 cubeposition = new Vector3(0,0,0);
?public Quaternion cuberotation = Quaternion.identity;//四元素初始化只能这样

?Matrix4x4 matrix = new Matrix4x4();
? ? ? ? ? ? ? matrix.SetRow(0, new Vector4(m[3], m[6], m[9], m[12] / scaleMultiplier));//经过实际测试前三个都是0，从第四个开始才跟transform中的数据一样，跟openIGTLink官方的协议说明不同，按实际的来，所以从m[3]开始
? ? ? ? ? ? ? ? matrix.SetRow(1, new Vector4(m[4], m[7], m[10], m[13] / scaleMultiplier));
? ? ? ? ? ? ? ? matrix.SetRow(2, new Vector4(m[5], m[8], m[11], m[14] / scaleMultiplier));
? ? ? ? ? ? ? ? matrix.SetRow(3, new Vector4(0.0f, 0.0f, 0.0f, 1.0f));

Vector3 eulerAngles = matrix.rotation.eulerAngles;
?GameObject.Find("newcube").transform.localRotation = Quaternion.Euler(eulerAngles.x, -eulerAngles.y, -eulerAngles.z);

?Vector3 markerposition = GameObject.Find("ImageTarget2").transform.position;//ImageTarget2?
?Quaternion markerrotation = GameObject.Find("ImageTarget2").transform.rotation;

cubeposition = markerposition + markerrotation * new Vector3(0, -0.03f, -0.114f);

cubeposition = markerposition + markerrotation * (cubeposition - markerposition);//此句虽然是用的向量加旋转，但依然是眼镜获得的两个全局值再运算，跟上面一个效果，多一层误差。

?public void XpositionPlus()
? ? {
? ? ? ?
? ? ? ? float result = 0;
? ? ? ? string textValue = XpositionInput.GetComponent<InputField>().text;
? ? ? ? result = float.Parse(textValue);
? ? ? ? Xadjustposition = Xadjustposition + result / 1000;
? ? ? ? cubeposition = new Vector3(Xadjustposition, Yadjustposition, Zadjustposition);
? ? ? ? GameObject.Find("newcube").transform.position = cubeposition;
? ? }? ?

//以下是rotation
? ? public void XrotationPlus()
? ? {
? ? ? ??
? ? ? ? float result = 0;
? ? ? ? string textValue = XrotationInput.GetComponent<InputField>().text;
? ? ? ? result = float.Parse(textValue);
? ? ? ? Xadjustrotation = Xadjustrotation + result;
? ? ? ? cuberotation = Quaternion.Euler(Xadjustrotation, Yadjustrotation, Zadjustrotation);

? ? ? ? GameObject.Find("newcube").transform.localRotation=cuberotation;
